VAT & reverse charge

BookSyncer works out the correct VAT treatment for each customer automatically and applies the matching e-conomic VAT codes — so cross-border invoices are right from the start.

VAT zones

For every customer, BookSyncer resolves a VAT zone from their country and VAT number:

• Zone 1 — home country. Domestic sales, standard VAT (25% in Denmark).
• Zone 2 — EU with a valid VAT number. Reverse charge applies; VAT is 0% and the customer accounts for it in their own country.
• Zone 3 — outside the EU. No EU VAT is charged.

Each zone maps to the VAT codes in your e-conomic agreement. Zones and codes are configurable per pipeline, and you can set overrides for the cases that don't fit the default rules.

VAT number validation

Reverse charge only applies when the customer has a valid EU VAT number. BookSyncer validates the number before applying zone 2 treatment. If the number is missing or invalid, the sale is treated as standard-rated rather than silently applying reverse charge — the safe default.

How it appears in e-conomic

The resolved VAT code is set on the invoice lines when BookSyncer creates the invoice, so the VAT reporting in e-conomic reflects the correct zone without any manual adjustment. For reverse-charge invoices, the appropriate e-conomic reverse-charge VAT code is applied.

Overrides

Real businesses have exceptions. You can override zone resolution and VAT codes per pipeline — for example to handle a specific customer group or a product that carries a reduced rate. The defaults cover the common cases; the overrides handle the rest.

This page describes the default behavior. VAT rules are your responsibility to confirm with your accountant; BookSyncer applies the configuration you set.
