Saves a draft sales invoice with item lines, dates and a tax template.

ERPNext API: https://cotlet.dev/docs/api/erpnext.md

`POST https://cotlet.dev/api/v1/erpnext/sales-invoices`

Access: write.

Saves a Sales Invoice as a draft and returns its ID and totals. A draft has no ledger effect and nothing is sent to the customer, and you can delete it in ERPNext, so this call does not ask for confirmation. The customer supplies the address, currency and price list defaults. Net total is the sum of the line amounts. To make the invoice final, call submit_sales_invoice.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `customer` | string | yes | Customer ID from list_customers. |
| `items` | array | yes | Lines as objects: item_code (from list_items), qty and rate. |
| `posting_date` | string | no | YYYY-MM-DD. Default: today. |
| `due_date` | string | no | Payment Due Date, YYYY-MM-DD. Decides when the invoice becomes Overdue. |
| `company` | string | no | Company name. Default: the default company of the signed-in user. |
| `taxes_template` | string | no | Name of a Sales Taxes and Charges template from your site. |
