What is the Sales Register?

The Sales Register records sales and sales adjustment documents for VAT and accounting. You submit document register requests with entry_type SALES or SALES_ADJUSTMENT and document_type INVOICE or CREDIT_NOTE.

When to use this API

Use the Sales Register API when:

• You need to register a standard sales invoice

• You need to register a sales credit note

• You need to record a sales adjustment (for example background adjustments or corrections)

How the Sales Register API works

When a sales register entry is created through the API:

1. The request is validated (mandatory fields, dates, amounts)

2. Supplier and customer party data is stored

3. The entry is recorded in the document register

4. The document is available for VAT and accounting reporting
