Create an invoice for a client, with lines, VAT and a due date.

Fatture in Cloud API: https://cotlet.dev/docs/api/fatture-in-cloud.md

`POST https://cotlet.dev/api/v1/fatture-in-cloud/clients/{client_id}/invoices`

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

Creates an invoice, auto-numbered when no number is given, and returns its ID, totals and e-invoice status. Totals are net, VAT and gross, and the due date becomes the payment due date. Creating the invoice does not send it to SDI; use send_einvoice for that. By default you confirm each call; you can switch that off for this tool.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `company_id` | integer | no | Company ID. Optional when your account has one company. |
| `client_id` | integer | yes | Client ID from list_clients or create_client. |
| `date` | string | yes | Invoice date, ISO. |
| `subject` | string | no | Subject shown on the invoice. |
| `e_invoice` | boolean | no | true issues it as an electronic invoice. Default: false. |
| `lines` | array | yes | Objects with description, quantity, net_price and vat_percent. |
| `due_date` | string | no | Payment due date, ISO. |

## 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.
