# Create invoice draft

> Save an invoice draft for a customer. Nothing is booked and nothing is sent. Input schema, a tools/call example and an example result.

Source: https://cotlet.dev/docs/mcp/fiken/create_invoice_draft

Docs sections: [Get started](https://cotlet.dev/docs.md) · [REST API](https://cotlet.dev/docs/api.md) · [MCP](https://cotlet.dev/docs/mcp.md) · [SDKs & CLI](https://cotlet.dev/docs/sdks.md) · [Integrations](https://cotlet.dev/docs/integrations.md)

Save an invoice draft for a customer. Nothing is booked and nothing is sent.

Fiken MCP tools: https://cotlet.dev/docs/mcp/fiken.md

MCP tool: `fiken_write → create_invoice_draft`

Access: write.

Saves a draft like Lagre utkast in Fiken and returns its draft_id. The draft shows under Utkast at the top of Salg → Faktura-/salgsoversikt, where you can open and change it. Nothing is booked, no invoice number is used and the customer hears nothing, so create_invoice_draft runs without asking first. Pass the draft_id to create_invoice to issue it.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `customer_id` | integer | yes | Contact ID from list_contacts or create_contact. |
| `issue_date` | date | no | Invoice date. Default: today. |
| `days_until_due` | integer | yes | Days from the invoice date to the due date. |
| `lines` | array | yes | Objects with description, quantity, unit_price (net per unit, excluding VAT), vat_type (for example HIGH, MEDIUM, LOW or NONE), optional discount_percent and income_account. A line without a product needs an income account. |
| `invoice_text` | string | no | Comment printed above the invoice lines. |
| `your_reference` | string | no | Your reference, printed on the invoice. |
| `currency` | string | no | ISO 4217 code. Default: NOK. |

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.
