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.
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.
- 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.
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.
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.
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.
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.Related
