Win closes a [Deal](/business/nouns/deal) as won, which places its [Order](/business/nouns/order) and makes the buyer a [Customer](/business/nouns/customer).

## Inputs
| Input | Type | Required | Description |
| --- | --- | --- | --- |
| `deal` | [Deal](/business/nouns/deal) | Yes | The proposed Deal. |

## Outputs
| Output | Type | Required | Description |
| --- | --- | --- | --- |
| `order` | [Order](/business/nouns/order) | Yes | The placed Order. |
| `deal` | [Deal](/business/nouns/deal) | Yes | The Deal, now won. |

## Effects
- Emits [`Deal.won`](/business/events/Deal.won).
- Performed by the [Sales Lead](/agents/sales/sales-lead).

## Refuses when
| Check | Error | Fix | Then call |
| --- | --- | --- | --- |
| The key is valid, but its scopes do not allow this operation. | [`forbidden`](/code/api/errors/forbidden) | Use a key whose scopes cover the operation, or ask an owner of the namespace to grant them. | [Deal.win](/business/nouns/deal/win) |
| The record is not in a state that allows this Verb, so the call is refused. | [`refused`](/code/api/errors/refused) | Read the record, run the Verb that moves it to an allowed state, then retry. | [Deal.win](/business/nouns/deal/win) |

## When it waits
| Gate | Default |
| --- | --- |
| Decision class | Low: two-way, nothing at stake |
| [Delay window](/systems/trust-and-governance/controls/one-way-windows) | None: it runs once review passes. |
| Limit | The call [Limit](/business/nouns/limit) of the [Permission](/business/nouns/permission) it runs under. |
| Over the Limit | It waits `pending` for an [Approval](/business/nouns/approval) from the [Founder](/agents/founding/founder). Approved, it runs; refused, it ends `refused` with [`limit-exceeded`](/code/api/errors/limit-exceeded); unanswered by its deadline, it ends `canceled`. |
