Book a supplier invoice as a purchase entry with its lines.

Exact Online API: https://cotlet.dev/docs/api/exact-online.md

`POST https://cotlet.dev/api/v1/exact-online/invoices/{invoice_number}/purchase-entries`

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

Creates a purchase entry for a supplier with its lines, in one call. It returns the entry number and total. Attaching the invoice PDF is not part of this tool. It writes to the ledger. By default you confirm each call; you can switch that off for this tool.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `division` | integer | no | Division (company) code from list_divisions. Default: the account's current division. |
| `supplier` | string | yes | Relation name or account_id from search_relations. |
| `invoice_number` | string | yes | The supplier's invoice number. |
| `entry_date` | date | yes | Invoice date. |
| `lines` | array | yes | Objects with gl_account, description, amount and vat_code. |

## 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.
