# One storefront. Every buyer. Every channel.

> How selling works on Semicola: a storefront, a storefront agent, and rules you write.

Buyers are sending their briefs to agents now. A media company that wants those briefs needs to be
reachable by an agent, answer in a form an agent can act on, and still sell the way its own team
would. A Semicola **storefront** does that. It publishes your listing to every buyer on the
platform, and its **storefront agent** reads each brief, composes a priced proposal from your
products in your voice, and hands the transaction to your ad server or sales agent once your rules
allow it.

## What a storefront is

| Part                  | What it holds                                                                             |
| --------------------- | ----------------------------------------------------------------------------------------- |
| **Listing**           | How buyers see you: description, channels, countries, logo and links.                     |
| **Inventory sources** | Where the inventory really lives: an AdCP sales agent you already run, or your ad server. |
| **Products**          | What you sell, with channels, formats, delivery type and priced options with floors.      |
| **Playbook**          | How your agent pitches, packages and prices: anchors, hard floors and discount caps.      |
| **Library**           | Media kits, rate cards, decks and past RFPs the agent learns selling points from.         |
| **AI Business Rules** | The written acceptance policy plus the two approval gates.                                |
| **Storefront agent**  | The hosted agent that answers briefs using all of the above.                              |

A storefront can also run as a plain **listing** without a hosted agent. In that mode briefs pass
straight to your connected sales agent, after a policy screen.

## How a brief becomes revenue

<Steps>
  <Step title="A brief arrives">
    A buyer's agent calls AdCP `get_products` on your storefront. Semicola records it as an RFP and
    opens a turn for your agent.
  </Step>

  <Step title="Your rules screen it">
    If the brief clearly conflicts with your written policy, no products are returned and the buyer
    gets a neutral reason. If the check is inconclusive, discovery stays open.
  </Step>

  <Step title="Your agent composes a proposal">
    A deterministic planner picks products that fit the channels, formats, budget and currency. The
    agent then writes the pitch: a name, why it fits, how the budget splits, and what it cannot do,
    never pricing below your floors.
  </Step>

  <Step title="The buyer selects and launches">
    When the buyer launches, an AdCP media buy arrives. With media-buy review on, it waits in
    **Approvals & operations** with an advisory verdict.
  </Step>

  <Step title="You approve and it forwards">
    On approval, the buy goes to your inventory source. The buyer's side flips to active and
    delivery starts to flow into both dashboards.
  </Step>
</Steps>

## Getting ready to sell

The **Get ready to sell** checklist (`open_seller_setup`) tracks what stands between you and your
first transaction: company identity, a listing with description, channels and countries, a healthy
inventory source, at least one complete product, a confirmed currency, an active acceptance policy,
reviewed approval settings, and a first practice brief. Each check says what to do next.

<Tip>
  In the app, switch to your storefront account and say "Let's set up rules for my agent." Semi
  opens AI Business Rules and walks you through a first policy.
</Tip>

## Billing in one line

Listing your own storefront is free. When your hosted storefront agent finishes a brief response, that
merchandising cycle costs one IU. Connecting, discovering and mapping never cost IUs, and Semicola
takes no share of media.
