URL: /business/nouns/quote/supersede · Id: `verb:Quote.supersede` · Call: `await $.Quote.supersede({ … })` (SDK) or the `do` tool at `https://api.sb/mcp`. Inputs says what to pass, Outputs what returns, When it waits who approves.

> Supersede replaces a sent Quote with a newer one on the same Deal; only the newest Quote can be accepted.

Supersede replaces a sent [Quote](/business/nouns/quote) with a newer one on the same [Deal](/business/nouns/deal); only the newest Quote can be accepted.

## Inputs
| Input | Type | Required | Description |
| --- | --- | --- | --- |
| `quote` | [Quote](/business/nouns/quote) | Yes | The Quote being replaced. |
| `by` | [Quote](/business/nouns/quote) | Yes | The newer Quote that replaces it. |

## Outputs
| Output | Type | Required | Description |
| --- | --- | --- | --- |
| `quote` | [Quote](/business/nouns/quote) | Yes | The superseded Quote, kept on record. |

## Effects
- Emits [`Quote.superseded`](/business/events/Quote.superseded).
- Performed by the [Sales Engineer](/agents/sales/sales-engineer).
- Two-way: it runs at once, in the `try`, `send` and `do` modes.

## 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. | [Quote.supersede](/business/nouns/quote/supersede) |

## 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`. |
