Source: https://cotlet.dev/docs/mcp/e-conomic/create_draft_invoice

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)

Create a draft invoice for a customer with lines. The draft is not booked.

e-conomic MCP tools: https://cotlet.dev/docs/mcp/e-conomic.md

MCP tool: `e_conomic_write → create_draft_invoice`

Access: write.

Creates a draft with the customer, date, currency, payment terms, layout and lines. The recipient name and VAT zone are copied from the customer. The draft stays editable and is not booked, so it reaches no one and runs without asking first. Lines take a product number or a free text with quantity and unit price. Returns the draft number and net, VAT and gross totals.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `customer_number` | integer | yes | Customer number from list_customers or create_customer. |
| `date` | date | yes | Invoice date, YYYY-MM-DD. |
| `currency` | string | yes | Currency code, e.g. DKK. |
| `payment_terms_number` | integer | yes | Payment terms number from the customer. |
| `layout_number` | integer | yes | Layout number for the invoice. |
| `lines` | array | yes | Lines: product_number (optional), description, quantity, unit_price. |
