# Sell your media on Apostra

> What Apostra does for a publisher or sales house, the two ways to sell, what each costs, and how to sign up.

Apostra is where brands, agencies and the agents that work for them find and buy media. As a publisher
or a sales house, you list what you sell in a storefront: your sites and apps, formats, audiences,
packages and prices. A buyer on Apostra can find your storefront, buy a product outright, or send you a
brief and get a plan back. You set the prices and the rules.

## What listing gets you

* **Buyers who can only buy from listed sellers.** A buyer on Apostra buys from sellers that have a
  storefront. If a buyer wants your inventory and you are not listed, they cannot buy it here.
* **Sales that land in your ad server.** Connect Google Ad Manager, or another
  [supported ad server](https://docs.apostra.com/v3/seller-connect-ad-server.md), and Apostra books each sale in it as an order with
  its line items. Your ad server still serves the ads and keeps your delivery numbers.
* **No cut of your media.** Apostra takes 0% of what a buyer spends with you, whichever way you sell.

## Two ways to sell

| | Listing | Storefront |
| - | - | - |
| Who answers buyers | Your own sales agent, or a third party's | A storefront agent Apostra hosts for you |
| Monthly charge | None | None |
| What Apostra charges | Nothing | \$5 per Intelligence Unit (IU), or €4.50 or £4 |
| What uses an IU | Nothing | Each completed brief response: 1 IU. Each media buy, in each month it is active: 1 IU |
| Share of your media | 0% | 0% |

**If you do not run a sales agent of your own, you sell with a Storefront.** The agent Apostra hosts answers
buyers for you, inside the prices and rules you set, and you pay only for the brief responses and media buys
it handles.

These are the list prices on the current Rate Card. The plan your organization accepts decides what you are
charged, and the live [Rate Card](https://app.apostra.com/rate-card) is the authority. The buyer pays Apostra
separately on its own plan, and nothing comes out of your media. The detail is in
[What you pay as a seller](https://docs.apostra.com/v3/plan-and-billing.md#what-you-pay-as-a-seller).

## Sign up

1. Sign up with your work email at
   [app.apostra.com/signup?intent=storefront](https://app.apostra.com/signup?intent=storefront).
   A personal address, such as a free webmail account, is not accepted.
2. Follow [From signup to your first booking](https://docs.apostra.com/v3/seller-first-booking.md). It walks a publisher on Google Ad
   Manager through every step: currency and markets, connecting the ad server, and the products buyers see.

You can do every step yourself in the Apostra web app, or hand the steps to your own agent.

## If a buyer sent you here

A buyer that wants to buy your inventory through Apostra may have sent you this page. Signing up and listing
your storefront is how they can buy from you. Once your storefront is live, other buyers on Apostra can find
it too.
