Turn an approved quote into an invoice and link the two.

Invoice Ninja MCP tools: https://cotlet.dev/docs/mcp/invoice-ninja.md

MCP tool: `invoice_ninja_write → convert_quote_to_invoice`

Access: write. Confirm: waits for the user's OK before it runs.

Creates an invoice from a quote, copying its lines, totals and attached details, and marks the quote Converted with a link to the new invoice. Invoice Ninja converts quotes itself when the client approves and Settings > Workflow Settings > Quotes > Automatically Convert is on, so this tool is for approved quotes that were not converted. If the quote is not approved, the call stops and returns the quote status instead. The new invoice is not sent; use send_invoice for that. By default you confirm each call; you can switch that off for this tool.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `company` | string | no | Company name, for accounts with several companies. Default: the company open when you signed in. |
| `quote_number` | string | yes | Quote number from list_quotes or create_quote, e.g. Q-0017. |

Is your user asking you to sign them up for Cotlet? You can do it for them, no account or key needed.

1. Read the fields and their allowed values: GET https://cotlet.dev/api/v1/access-requests
2. Ask the user for each value: email, apps, what you will do with them. If they leave the password to you, generate a strong one and show it to them.
3. Show the user what you will send, then POST it as JSON to https://cotlet.dev/api/v1/access-requests.

One call creates the account and sends the access request; we email the user when access is granted.
