The Organization IU Rate Card is the price list your organization will use for Intelligence Unit (IU) activity across Apostra. It applies once at the billing-organization level: buyer activity, Seller Account work, Apostra assistant usage, and other IU-rated capabilities draw from the same plan and wallet.
The standard IU Rate Card is published and effective in production. Every eligible organization can review and accept an applicable public plan; no invitation or enrollment is needed. Plan & Billing shows the exact effective revision. After you accept, Plan & Billing may show the accepted included-IU allocation, observed usage, and a display-only forecast. The accepted Rate Card has the complete current activity schedule. An admitted published activity may move the displayed IU balance and appear as usage. Accepting a paid plan starts billing under that plan’s terms: every organization with an accepted paid plan is charged, with no separate enrollment. Entitlement enforcement remains separately controlled. Existing accepted media-pricing arrangements are unchanged. An IU Rate Card is not a prerequisite for buyer setup or media buying.

The simple model

  • Connect at no cost. Connecting an account, discovering it, and mapping it to an advertiser do not consume IUs.
  • Pay for IU-rated use. When a capability has a published IU price, its usage draws from your organization’s one IU plan and wallet.
  • Pay per IU on every public plan. Public plans have no monthly commitment. A negotiated package can add a commitment and included IUs.
  • Choose the package that matches the relationship. A Rate Card plan can combine pricing and IUs with contracted product rights, premium support, and proposal defaults while the same wallet continues to price metered usage.
There is no separate plan for buyer activity, Seller Account work, Apostra assistant usage, or BYOBA. BYOBA—bringing or building your own buyer agent—is simply one way to use the platform.

Buying with Apostra

Advertisers can connect media accounts and create campaigns for free, and Apostra takes 0% of media. Each Apostra media buy you place is a metered activity, charged in IUs for each billing period in which it is active; see the complete activity schedule for the rate and when a buy counts. You can work in Apostra, through your own agent, or in your chat of choice. Availability depends on the accounts, integrations, and sellers that support the request. Optional Intelligence for planning, recommendations, and enhanced reporting is currently in beta. The activity catalog sets Enhanced Reporting at 4 IUs per connected account per billing period, and no plan in the current template waives it. Customer-facing plan pricing for other buy-side Intelligence activities is coming soon. Apostra shows the resolved price before you opt in, and eligible activity draws from one IU wallet shared across your organization. Enterprise is a contact-us offer. A scoped agreement can include the Apostra team operating Apostra for you, custom integrations, cooperative agent development with forward-deployed engineers, dedicated human support, and enterprise governance controls. The proposal or statement of work defines the services, responsibilities, support commitments, and price. Ordinary product support through Apostra remains part of the product. Connect & Buy covers Buyer Accounts. Business Manager is for agencies and teams that run many brands: it covers Buyer Accounts under one organization, on one IU bill. It is a public plan at the same price as Connect & Buy, so any buyer organization can choose it. These are buy-side choices, not Seller Account plans. The Effective Rate Card governs any IU activity your organization accepts, while a separate Enterprise agreement governs contracted services.

Before you choose a plan

Nobody is placed on a plan. An organization with no accepted plan in force, because nobody has accepted one yet or the accepted plan ended, has not chosen a plan yet:
  • Its next action in Plan & Billing is Select an IU plan. Seller administrators are also asked to choose at every sign-in.
  • It cannot add accounts until it has chosen a plan, because a plan’s account limit is what allows another account. The refusal says to choose a plan in Plan & Billing.
  • A Seller’s brief responses are refused with the same next step only where Apostra has turned that enforcement on for the Seller. It is not on for everyone yet, and buyer activity is not refused. Reading, setting up, and work that is always free stay open.
Choosing the pay-as-you-go plan with no monthly commitment counts as choosing. The chooser puts first the plan that fits what your organization holds today:
  • Connect & Buy for Buyer Accounts.
  • Listing for Listing-only storefronts.
  • Storefront agent for Agentic Media Company storefronts, with or without Buyer Accounts.
  • Developer for an organization whose accounts are all Developer accounts.
That plan is only a suggestion. Your organization is not on it, nothing is billed under it, and it does not decide which accounts you can add. Accepting it makes it your organization’s plan. The v4 IU Rate Card read reports the suggestion as suggestedPlan and the next step as nextAction: SELECT_IU_PLAN. suggestedPlan is null while an accepted plan is in force, and for an organization no such plan covers, such as one holding Buyer Accounts beside a Listing-only storefront. That organization uses Get in touch. The earlier defaultPlan field is deprecated and always null: nothing governs an organization by default any more.

Building your own agents

An organization whose accounts are all Developer accounts, where its agents live, can accept the public Developer plan. It has no monthly commitment. It covers registering, testing and certifying the organization’s own agents, and the Agent page. IU-rated activity, if any, uses the standard overage rate of $5, €4.50 or £4 per IU. Developer does not include buyer or seller tools. Operating agents for other companies needs the Certified Agent Partner Program, and adding a Buyer or Seller Account needs a plan that covers it. Developer accounts are in a closed preview.

One Effective Rate Card

The Rate Card shown for acceptance is the complete commercial result for your organization. Each plan on an exact published Rate Card revision is a complete commercial package: its pricing and IU allowance, entitlements, support, and proposal defaults travel together. It can incorporate one authorized adjustment source:
  • a corporate percentage adjustment;
  • a promotion or referral code;
  • a negotiated private package, such as 500 IUs for $500; or
  • an explicitly customized version of one published plan.
These are not separate terms scattered across the product. A Commercial Offer or code distributes the terms; the resulting Effective Rate Card is what you review, accept, and later see in Plan & Billing. It is versioned and snapshotted with the acceptance record so a later edit cannot rewrite what you accepted. Entitlements are enforced separately from billing, but the access bundle and support included in a plan appear beside its price. A new Offer selects one exact Rate Card revision and plan. It either uses the standard plan terms or records an explicit customization with its reason and exact differences. The Offer snapshots the resolved bundle revision, every canonical feature key it contains, any premium-support package, and the resolved proposal. A later plan or bundle revision cannot change an Offer already issued or a term already accepted. Draft revisions also preserve their commercial lineage. A successor identifies the published revision it carries forward; a deliberate fresh start records why no predecessor terms apply. If an operator abandons an unpublished draft, Apostra retains its terms, lineage, actor, timestamp, and reason as immutable audit history. An abandoned draft is never published, offered for acceptance, or used to price activity, and it does not alter any revision your organization accepted.

Choosing a seller plan

The plan chooser groups seller plans under Listing and Merchandising. Listing choices include Listing and Listing + Distribution. Merchandising choices are the Agentic Media Company plans: Storefront agent and Storefront agent + Distribution. The displayed price and included access always come from the published revision offered to your organization. A plan name does not set a price or change your accepted terms. The available choices follow your organization’s active products. A seller that only lists its Sales Agent sees Listing choices. A seller whose storefronts are all on Agentic Media Company can see both groups, because a Listing plan also covers an Agentic Media Company storefront. A public plan for an organization with several products must cover all of them, so an organization that also holds Buyer Accounts or a sales agent offering sees only Merchandising choices. If no public plan fits, the chooser offers Get in touch. Your plan also decides which accounts the organization can hold: No plan limits how many Buyer or Seller Accounts an organization holds; the plan decides only which kinds of account it may hold. A plan’s terms can still record an account count from an earlier Rate Card revision, and it does not limit anything. An organization holds one Developer account, on every plan. See Accounts in an organization. Adding a Buyer Account to a Seller organization on a Listing plan would make it both buy and sell. It needs an Agentic Media Company plan, and the change is refused until the organization has one. Global Market Maker is the one exception: a private seller plan that also covers Buyer Accounts and a sales agent offering, even when the storefront is Listing only. See Which plan holds which accounts. Enterprise — Listing and Enterprise — Storefront agent are contact choices for the applicable Listing or Merchandising group. They have no public price and cannot be accepted as a zero-priced plan. Any private Commercial Offer prepared for your organization returns to this same chooser for review and acceptance.

Getting help with a plan

Select Get in touch in plan selection, including when public plans are available. You can also open the chooser from Plan & Billing. A billing administrator must send the request from their own account. Staff impersonation and service tokens cannot send it on your behalf. Add an optional message of up to 1,000 characters and select Send request. Replies stay in the app. Your request is tied to the plans you were shown and the plan choice you asked about. It does not accept a plan, change pricing or access, or promise a response deadline. Retries of the same current request are attached to the same commercial request. After Request received, follow progress in Your requests, under Help in Apostra, when tracking is available. If tracking is temporarily unavailable, keep the reference when asking for an update. Back to plans reloads the current offer. If the available plans changed, no request is sent. Review the current plans, then send again. During signup, Get in touch explains how to continue after account creation. Nothing is sent anonymously. Finish creating your account, then send the request from Plan & Billing. Seller signup does not ask for your seller product separately. It shows every public plan that applies to a Listing-only Seller or to an Agentic Media Company, and the plan you accept sets your starting product. A Listing plan, or no paid plan, starts you as Listing only. A Storefront agent plan starts you as an Agentic Media Company, because Merchandising comes with the Merchandising plan. After signup, the product follows your plan: change it in Settings → Plan & Billing. A paid plan you choose while creating a Seller account is accepted as part of that signup, once your email address is verified, even though your Seller Storefront is created a moment later in the same signup. The plan takes effect when signup completes. Only an accepted plan sets your starting product. If your email is not yet verified, or the plan you picked is no longer offered when you finish (for example because the Rate Card changed while you were signing up), signup finishes on the free pass-through terms as Listing only and asks you to choose a plan again. To choose a Storefront agent plan after that, open Settings → Selling mode and choose Compare plans, which records your intent to merchandise so the Merchandising plans are offered.

Rate Card plans

Rate Card revisions can contain public plans and private negotiated packages. The seller templates use Listing, Listing + Distribution, Storefront agent, and Storefront agent + Distribution. A template is an unpublished starting point: an operator must approve and publish an exact revision before it can be offered. Buyer and other product plans may also appear when they cover your organization’s products. Saving, enabling, and evaluating AI Business Rules is not an IU-rated activity. No plan in the current template waives Enhanced Reporting; it carries the catalog default of 4 IUs. Listing paths waive brief responses and qualifying media buys. Merchandising paths—the Storefront agent plans—keep the catalog’s 1-IU defaults for brief responses and qualifying media buys. The current production Rate Card publishes Listing and Storefront agent for sellers, Connect & Buy and Business Manager for buyers, and Developer for organizations that build their own agents. Existing accepted plans remain readable and enforceable. The commitment, included quantity, overage rate, activity terms, product rights, support, and proposal defaults belong to the selected plan. None of the public plans has a monthly commitment or included IUs. The standard price per IU in each currency, with worked examples, is on How IU billing works. That page is the standard list; this page is about the exact revision and plan that govern your organization. A plan with no commitment has no included monthly IU allocation, and its usage is billed after each monthly period. When a negotiated package carries a commitment, the commitment is billed at the start of each monthly period and usage beyond its included IUs is billed after the period. The standard plans are published in production. Your confirmation always shows the exact version, term, list price, and effective price that apply to you. The same Rate Card includes the complete activity schedule; several rows remain under calibration and are marked non-billable below. Whatever the standard list says, your Effective Rate Card is the authority. An authorized corporate discount, a promotion or referral code, a negotiated private package, or a customized Offer replaces the standard figures, and Plan & Billing shows the list price and the effective price side by side before you confirm. If your organization has been quoted something else, that quote — once it is an Effective Rate Card you accept — is what governs your charges. Prices are also published per currency rather than converted, so a card in EUR, GBP, or AUD carries its own published numbers.

Pricing adjustments and private offers

If Apostra has authorized a corporate discount for your organization, it applies once across the plan—not separately to buyer and Seller Account activity. Before you confirm, Plan & Billing shows the list price, discount, and effective price. Discounts do not stack. A negotiated package is shown as its own private Effective Rate Card, not as a second hidden discount. For example, an Offer for 500 IUs at $500 shows that commitment, included quantity, and overage price directly. It also shows the selected plan’s entitlement bundle, support, and activities that are included rather than IU-rated. The package price is the complete subscription economics; there is no second “platform access” fee. Only one complete Offer is effective for acceptance at a time. A later discount or Rate Card change never rewrites an accepted term. Changes apply through a new offer or successor term that you can review.

Product access and premium support

When a plan includes product access, the Offer shows an immutable bundle identity and revision plus the exact feature keys included. Apostra validates those keys against its canonical feature registry before issuing the offer. An unregistered feature, an alias in place of its canonical key, or a feature that is not contract-gated cannot be issued as an authoritative entitlement bundle. A plan can also include premium support. The Offer preserves one of two simple forms: unlimited premium support, or a monthly premium package with included hours. Additional support follows the Enterprise agreement or statement of work; it is not an automatically metered IU activity. Coverage windows, severity targets, onboarding allowances, and escalation policies are not separate commercial fields. The proposal’s Included scope and the structured premium-support package are separate terms. The customer view shows every included-scope line exactly as the server-authored proposal records it, while it shows a named support package only when the Offer carries one. A scope line must not be silently converted into a support package, or vice versa. If its meaning is unclear, the issuer and customer must resolve it in the audited Offer preview before acceptance; a Task does not infer a support commitment from ambiguous wording. Acceptance preserves these exact product and service terms in the acceptance record and creates each contracted product right against that same record atomically. Runtime-gated rights become usable only while the accepted terms and governing contract are in force. The paid right to operate agents for clients is one such runtime right; sales-agent registration access, registration, deterministic certification, and certification evidence are free and cannot be sold in an entitlement bundle. Setup rights remain explicit fulfillment obligations; acceptance does not silently assign a support owner or bypass payment standing for chargeable operations. Each plan also declares the default feature profile that presents those rights as one coherent product experience. The profile is not a second plan or an independent grant of access: Apostra validates that every entitlement the profile requires is included and active. When you accept a plan, its entitlements and default profile are provisioned together; if they are incompatible, neither change is applied. An approved beta or operator-assisted profile transition follows the same rule and cannot add a commercial right that the organization does not already hold. Renewals preserve the accepted profile revision with the successor term rather than silently adopting a later profile definition.

Rollover

Rollover applies only to a plan with included IUs, which today means a negotiated package; the public plans have none to roll over. On such a plan, unused included IUs can carry into the next monthly period, up to 50% of that next period’s included quantity. A package with 250 included IUs can carry at most 125. Carried IUs expire after that one successor period and cannot accumulate again. Setup and promotional credits never roll over.

Enhanced Reporting

Connecting and mapping an account costs nothing. The catalog default for Enhanced Reporting is 4 IUs per connected account per billing period after its account-level control is enabled and that exact account’s existing reporting subscription completes a successful sync. The control is set for one exact connected account; it does not enable sibling accounts or change ordinary connection and campaign features. An enabled account without a reporting subscription or successful sync draws no IUs. Enhanced Reporting is a required term on every new Rate Card, and no plan in the current template waives it. A Rate Card that does not mention Enhanced Reporting carries the catalog default. Ordinary connection, synchronization, and campaign actions are included. This is an activity term, not a buyer plan. The selected plan resolves the catalog default before acceptance. For example, five eligible accounts would have a 20-IU total per billing period at the catalog default. A Rate Card or plan that sets another price, or waives Enhanced Reporting, changes that total.
The catalog default of 4 IUs applies unless your accepted Rate Card or plan sets another price or waives the activity. Usage & credits applies the resolved terms from your accepted Rate Card. A future customized Offer would have to show any different activity term before acceptance. Accepting a paid plan is what starts billing—see Billing cycle and fee invoices.
The 4-IU count is the current standard, not a final one. Your accepted version is what applies to you: a change reaches you only through a successor Rate Card that you accept, and it never reprices a period already metered.

Complete activity schedule

Every Rate Card shows the same complete activity list. Each row starts with the catalog unit and price. The selected plan then applies its activity terms, and a Commercial Offer can apply an authorized customer-specific adjustment after that. Either layer can set a custom IU price or waive the activity; an activity without an override keeps the preceding value. Acceptance freezes the resolved result, so later catalog, plan, or Offer changes cannot rewrite it. The row status is part of the Rate Card. Published means an admitted meter may debit the accepted IU balance. The v4 catalog contains exactly the three published rows below. The accepted Rate Card freezes its catalog version and resolved rows, so later catalog changes do not rewrite the agreement. Existing accepted v0-v3 Rate Cards keep their earlier catalog and terms. Historical agreements that predate the complete schedule retain only the activity charges they explicitly contained. Showing the newer catalog does not add a charge to one of those agreements; an activity absent from that immutable snapshot stays absent until a successor Offer is accepted. An Apostra media buy is charged to each side whose plan prices it, so the buyer and the seller can each be charged 1 IU for the same buy and billing period. An organization buying its own inventory is charged once: for a non-social buy that is the seller’s charge, which needs positive impressions or spend in the period, so a buy of your own inventory that has not delivered in a period is not charged for it; a social buy of your own inventory is charged once, as the buyer’s charge. For the buyer, a media buy counts once it has left draft and the seller has accepted it: it is confirmed, active, paused, ending, or completed. It does not count while it is a draft or waiting for approval, if the seller rejects it, or if it is canceled before its flight starts. A buy counts in each billing period in which it is active, so a buy running across a period boundary counts in each period. Billing periods follow your organization’s IU billing cycle and are measured in UTC. A buy that was already running is not charged for a new period it only spills into for less than 24 hours (a flight ending at 7 PM London time on the first day of a period does not count for that period); the first period a buy is active always counts. A buy that carries a percentage-of-media fee above 0% is not charged to the buyer as an IU; a buy created at 0% is charged normally. For the seller, qualification uses the latest authoritative delivery totals for that buy and billing period, and social buys are not charged. If a correction leaves both impressions and spend at zero before invoicing, the provisional IU is removed. The buyer’s unit is instead removed before invoicing if the seller rejects the buy or it is canceled before its flight started. If the correction arrives after invoicing, it is handled through the normal auditable one-IU credit or reversal process against the original period. A later positive correction can reinstate the same unit once, but cannot create an additional unit for that buy and period. For what a plan with no monthly commitment charges for, by buyer and seller, see how IU billing works. Customer approval actions, retries, routing, caching, and internal model calls never create additional charges. Human expert support and Apostra-operated modular-source fulfillment are contracted managed services, not metered IU activities. Custom modular-source composition is included with Premium and Enterprise through the Merchandising profile, not a per-source usage charge or separate entitlement.

New Seller Account setup credit

A Rate Card may or may not carry a setup credit. Plan & Billing shows the credit, if there is one, before you accept, and a Rate Card that carries none grants none. The current plans carry no setup credit. A credit belongs to the Rate Card revision it was published with, so a later revision can drop it without affecting a credit an organization already holds: that credit stays until it expires. A signup code works whether or not the Rate Card carries a setup credit: its price or access adjustment and its attribution apply either way, and with no credit it grants no IUs. When the effective Rate Card carries a setup credit, a seller billing organization receives the amount of IUs the Rate Card states on its first IU plan acceptance. You do not need to be a new customer: if your organization has been with us for a while and is accepting an IU plan for the first time, the credit is yours too. The credit is valid for the number of days the Rate Card states, and it can be spent on any IU-priced activity — it is not limited to setup work. Those days run from your signup commit as a fixed window, not a number of billing periods, so it does not move with your billing cycle. Usage & credits shows the exact expiry date rather than asking you to derive it. Seller Account provisioning may complete asynchronously without moving that window. One credit per billing organization: later Seller Accounts do not create additional credits. It does not roll over, has no cash value, and does not stack. A valid promotion or referral code can attribute the same credit and may carry an authorized pricing or access adjustment, but it cannot add a second credit or change the program’s value or expiration. A code that is limited to a number of redemptions counts every organization that used it, whether or not that organization received a setup credit. The preview is recomputed after the code is entered, and the adjusted Effective Rate Card—not the code itself—is the accepted record. The setup credit is part of the published Rate Card and does not create billable usage.

Acceptance and renewal

When an effective Rate Card is available, Settings → Plan & Billing shows:
  • the exact Rate Card version and effective date;
  • every eligible plan size;
  • your complete Effective Rate Card, including any corporate adjustment, promotion, referral, or explicitly customized package;
  • the exact entitlement-bundle revision, included feature keys, and premium-support package when the offer carries them;
  • a frozen customer proposal, when assigned, containing the scope, initial term, renewal and notice terms, and the exact monthly and/or term-prepayment choices;
  • included IUs, rollover, overage, billing timing, and term; and
  • the governing agreement and renewal posture.
The online proposal and its downloadable PDF come from the same immutable Offer snapshot. The PDF is labeled Draft — not yet accepted until the Offer has been accepted. An accepted PDF records the canonical Offer version, acceptance date, and selected payment choice; alternatives remain visible as not selected. If the negotiated terms change, Apostra revokes or supersedes the Offer and issues a new version; it does not edit the version you were sent. The organization name on the proposal comes from the organization account, not from a separate sales profile. If it is incorrect, Apostra updates the organization record and issues a new Offer. Billing contacts, payer name, tax information, and billing address likewise remain in the organization’s Billing information. When an Offer contains multiple payment choices, the administrator selects one before accepting. The client submits only that option’s key; Apostra resolves and stores the complete frozen option as immutable acceptance evidence. A full-term prepayment is one exact price in the Offer currency for the complete service term; it is not a partial-term payment or a rounded number of monthly payments. After acceptance, Set up payment opens the organization’s payment setup. Automated term-prepayment collection is not yet self-service, so Apostra coordinates its invoice or ACH funding separately and does not run monthly base charges for that schedule. After acceptance, you may also see the exact included allocation, remaining balance, overage rate, rollover policy, observed usage, and projected month-end usage on Usage & credits. These figures do not create charges or enforce entitlements. Only a verified organization administrator can accept a plan. An agent, API credential, service account, or impersonated support session cannot make that financial commitment. If the offer changes while you are reviewing it, the confirmation reloads and asks you to review the new version. Signup may present the current Terms of Service and IU Rate Card in one flow, but the acceptances remain distinct: the record preserves the exact agreement, Rate Card version, selected plan, complete adjustments, prices, actor, and time. An existing organization without an accepted plan will receive the same Choose an IU plan action after a Rate Card becomes effective. Apostra never silently accepts a paid plan on its behalf. The plan task also lets an administrator Continue without a paid plan or Decide later. Continuing without a plan dismisses automatic login prompts for only the exact Rate Card revision reviewed; a successor revision may be shown again. Deciding later allows Apostra to show the task on the next login. In either case, Settings → Plan & Billing keeps the manual Choose an IU plan action available while the offer remains current, so you can return without waiting for another prompt. One acceptance applies to the billing organization. If you accepted from a Seller Account task, the buyer view shows the same plan; if you accepted from a buyer task, the Seller Account view does too. The Standard plan renews onto the newest IU Rate Card revision whose written notice went out at least 30 days before the new term starts, and keeps any discount or code adjustment it already has. With no such revision it renews on its current terms. Other public plans and private offers marked pin exact renew through immutable monthly terms at the accepted price. An offer marked review required stops before automatic renewal and requires a new explicit commercial decision. A later Rate Card or adjustment never silently reprices the current term. Ending the IU plan at term is an organization-wide decision: it prevents the next shared plan term from starting, rather than ending only one buyer or Seller Account capability. Individual capabilities are enabled or disabled separately.

Billing cycle and fee invoices

Once you accept a paid plan, your IU plan bills on the calendar month, measured in UTC. Every accepted paid plan is billed this way, whether you pay by card or by invoice, and whatever day you accepted it. There is no separate enrollment:
  • Commitment at cycle start. The plan’s monthly commitment is charged at the start of each calendar month, at the price fixed in your accepted terms.
  • Overage during the cycle. Usage beyond your included and rolled-over IUs accrues as overage at your plan’s per-IU rate. For organizations paying by card, accrued overage is charged automatically once it crosses a threshold, so month-end never brings one large surprise; any remainder settles when the cycle closes.
  • A fee invoice at cycle close. Every charged month produces a numbered fee invoice — plan commitment, overage (IUs × rate), and payments applied — on Settings → Plan & Billing → Payment & invoices. Invoice numbers are sequential with no gaps, and an issued invoice’s charges never change; payments are appended as they settle.
  • Nothing from before your plan. Usage before the moment you accepted your plan is never billed. A billing period that ended before you accepted is not charged or invoiced, and in the period in which you accepted, only usage from acceptance onward counts, at your plan’s rates and with its included IUs and credits.
Your first month is prorated. The month you accept the plan is billed as a partial cycle: the plan commitment and the included IUs are both scaled by the days remaining in that month, counting the day you accepted as a full day. Your usage for the whole month is still rated, and no later month is prorated. A plan accepted on 15 July, for example, owes 17 of July’s 31 days. Moving to calendar months. Before 1 November 2026, an organization paying by card was billed on cycles that began on its acceptance day. Such an organization keeps those cycles until 1 November 2026. A cycle that would run past that date ends on 1 November instead, so it closes with one invoice for the shortened period. If an organization’s usual renewal date falls in October, its cycle closes on that date as before, and a short final cycle from that date to 1 November closes with its own invoice. Calendar months start on 1 November. An organization paying by card that accepts its plan before 1 November has a first cycle that runs from acceptance to 1 November, prorated by days like any first month. Nothing already charged or invoiced changes, and nothing is charged twice for a shortened cycle. A cycle already closed keeps the dates it was closed with. Apostra can pause IU charging for every organization at once. While it is paused, no new commitment or overage charge is made, overage still accrues and stays visible on Usage & credits, and no overage line is added to a fee invoice, so a month in which you used more than your included and rolled-over IUs can invoice as the commitment alone. Payments already collected are still applied and their cycle still closes with an invoice. Overage that a closed month did not bill is not collected later: issued invoices never change. When charging resumes during a period, overage already accrued in that same open period becomes chargeable. Organizations paying by card are charged automatically against the saved card. Invoiced organizations receive the fee invoice only and pay on their existing terms — no card charge is made. If a card charge fails, the standard payment recovery ladder applies: retries on a published schedule, email notices, and a self-serve pay now action on Plan & Billing that clears the failed-payment status once it succeeds. Plan & Billing also reports unresolved dunning-backed holds, while reaching the account’s cap records an internal hold. In the current alpha, neither hold is consulted by a production authorization path, so it does not automatically block new paid platform activity. Viewing, reporting, exporting, and fixing your payment method remain available.

For agents and API clients

GET /api/v2/billing/iu-rate-card is the canonical organization offer read. GET /api/v2/billing/fee-invoices lists the organization’s fee invoices, and GET /api/v2/billing/fee-invoices/{invoiceNumber} returns one invoice with its line items. Agents should use the typed open_iu_plan_task tool to open the same portable plan-selection task rather than reconstructing it from a generic API call. Its model-visible receipt is deliberately bounded; the authenticated app receives the exact commercial state. get_iu_rate_card_offer remains available only as a compatibility read for deployed clients. Acceptance and renewal changes are direct human commitments. The task invokes app-only operations to append the displayed, declined, deferred, or accepted outcome and to schedule or reinstate renewal. Every response is idempotent and tied to the exact Rate Card revision; an accepted outcome links to the immutable acceptance record. These commit operations are not model-visible. The older storefront-rate-card REST paths and storefront-named tools remain deprecated compatibility aliases; new clients should use the organization IU names.

Separate from media pricing

IUs price platform activity. Existing media-pricing arrangements cover media spend and their accepted contract fee terms. This Organization IU Rate Card does not replace, amend, or silently remove those terms. Plan & Billing can show both because an organization may owe both platform/IU charges and media charges, but each is a separate commercial stream.
