This is a practical setup library that helps you understand what data, workflows, and channel settings are required to send compliant invoices through DDD. Use this page when setting up DDD for a new country or troubleshooting why an invoice did not process correctly.

Start with the country you are working on, then choose the section based on what you need to solve:

(DDD Steps) What should DDD do with the invoices? → Steps / workflows

What data (About the company, buyer…) do I need before we start processing compliant invoices? → Specific data points

Where should the invoice be sent? → Delivery channel setup

What does this local term or rule mean? → Local tax questions

Untitled

Use this section when you need to know which fields must be added in Stripe, Bitrix, API payload, or another source system.

This can include: VAT number, buyer registration number, product tax code, exemption code, metadata key/value, customer data, product data or required value formats.

Tip: Start here if an invoice failed because required data was missing or entered in the wrong format.

Specific data points for countries

Use this section when you need to know what DDD should do with the invoices and when.

Examples: process on invoice issue, process after payment, generate XML, fiscalize, archive, report, use customer-specific flow…

Tip: Start here if the invoice data is correct, but the invoice is stuck, processed at the wrong time, or follows the wrong flow.
