Record a supplier bill as a purchase, as a draft or approved.

Holded API: https://cotlet.dev/docs/api/holded.md

`POST https://cotlet.dev/api/v1/holded/contacts/{contact_id}/purchases`

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

Creates one purchase for a supplier with the number printed on the supplier's bill. Each line needs an expense account, because Holded needs one for the ledger. With approve false, the default, the purchase is saved as a draft. Approving makes Holded create the accounting entry. Optionally attach the bill by link. By default you confirm each call; you can switch that off for this tool.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `contact_id` | string | yes | Supplier contact ID from list_contacts. |
| `document_number` | string | yes | The supplier's own document number. |
| `items` | array | yes | Lines of the document. Each line has name, description, units, price and tax (the tax as named in Holded). Optional discount in percent per line. Use a product from list_products or a new name. |
| `date` | date | no | Bill date. Default: today. |
| `due_date` | date | no | Due date. |
| `deduction_date` | date | no | Controls the tax period for the deduction. |
| `attachment_url` | string | no | HTTPS link to the bill file to attach. |
| `approve` | boolean | no | true approves the purchase, false saves a draft. Default: false. |

## For AI agents: sign your user up

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.
