What it does

German merchants hand their bookkeeping to a tax adviser who works with DATEV. This add-on turns your CS-Cart or Multi-Vendor orders into the file the adviser imports: a booking batch in the DATEV format and a debtor master data file. It is an export file for your tax adviser: not DATEV-certified, no connection to DATEV online services. DATEV is a trademark of DATEV eG.

How it works

Enter the consultant and client numbers of your adviser, choose SKR03 or SKR04 and confirm the preset accounts. Under Orders > DATEV export choose the period and order statuses, press Validate, then download the booking batch. Customers can be booked on one collective debtor or on their own debtor numbers, with a master data file. Credit notes are booked Haben. Vendors in Multi-Vendor export their own orders.

Is this DATEV-certified? Does it connect to DATEV?

No. It creates an export file for your tax adviser, following the DATEV format description published on the DATEV developer portal. It is not DATEV-certified and does not use DATEV online services or APIs. DATEV is a trademark of DATEV eG; this product is independent of DATEV eG.

Will my tax adviser's DATEV accept the file?

The file follows the published layout (header, 125 booking columns, Windows-1252, decimal comma). The add-on is tested against the official DATEV sample data. Account numbers, tax keys and fiscal-year rules are specific to each client, so send the first file to your adviser as a test before you rely on it.

Which VAT cases are covered?

Domestic 19 % / 7 % / 0 %, intra-community supplies (reverse charge) for EU orders without VAT, tax-free exports, OSS per delivery country, shipping and payment fees. Not covered in 1.0: foreign currencies, fixed-amount taxes, margin schemes, partial payments over several bookings, cost centres, document images (Beleglink).

Why is my order not in the file?

Only orders in the selected statuses are exported, once (see "Only documents that were not exported before"). Parent orders of Multi-Vendor are not exported, their vendor orders are. Open the validation report: orders with errors are listed there.

Which invoice number is used?

Belegfeld 1 is the invoice number of our Invoices & Credit Notes add-on when it is installed and used; otherwise the order number with your optional prefix.

Does it work with Multi-Vendor and Ultimate?

Yes. Vendors (Multi-Vendor) and storefronts (Ultimate) can have their own settings. See Configuration.

Which CS-Cart versions are supported?

4.17.2 to 4.21.x, PHP 7.4 to 8.3.

Will it slow down my store?

No storefront output at all: the add-on only runs in the admin panel and from the cron command. A large export reads the orders of the period once.

How do I get updates?

Install the new package over the old one. See Installation.
