Rechnungskit vs. Taxdoo

Taxdoo alternative for online sellers after the end of the VAT service

By · Published · Updated

Rechnungskit carries on what many used Taxdoo for: OSS data preparation, monitoring of the €10,000 threshold, EU tax rates and DATEV handover, plus something Taxdoo never was: compliant ZUGFeRD invoices straight from your shop. The actual filings are done by your tax advisor or a compliance provider.

The short version

Rechnungskit fits if …

after the end of the Taxdoo VAT services you need a lasting solution for OSS data, EU tax rates and DATEV, and want to automate invoicing at the same time.

Taxdoo fits if …

you want complete, up-to-the-day multichannel financial accounting: the new TAXDOO Accounting is a bookkeeping product. Rechnungskit does not replace bookkeeping.

For context: according to its own announcement, Taxdoo discontinued its VAT compliance services (OSS filings, registrations) on 30.04.2026 and referred customers to Marosa; today's product is AI-driven accounting. Rechnungskit is not accounting software. It automates invoices and delivers OSS data and DATEV bookings. Either way, you need a tax advisor or compliance provider to file the returns.

When is Taxdoo the better choice?

Rechnungskit doesn't do everything. In these cases, Taxdoo is the more honest recommendation.

You want complete bookkeeping

TAXDOO Accounting is up-to-the-day multichannel financial accounting with AI account assignment and expert review. Rechnungskit does not replace accounting.

Booking incoming documents automatically

Invoice fetching and AI account assignment for incoming invoices are part of Taxdoo; at Rechnungskit they are out of scope.

Lots of channels on the accounting side

Taxdoo connects shops, banks, credit cards and payment systems on the accounting side; actual capacity depends on the plan.

What Rechnungskit does differently

Invoicing

Invoicing on the correct date of supply

Shipped goods are invoiced on the shipping date, not the payment date. It sounds like a detail, but it decides which period the revenue lands in.

Date of supply (Leistungsdatum) from the shop's shipping event
Small-amount invoices automatically under §33 UStDV
Handover to DATEV in the right period
Tax compliance

VAT ID check with evidence archive

Qualified check with the BZSt (Federal Central Tax Office) including company name, city, postcode and street. The response is archived unchanged for eight years and linked to the individual invoice.

Qualified BZSt check instead of a simple format check
Response linked to the invoice and delivery date
No tax-exempt invoice without a usable check
Accounting

DATEV bookings with linked documents

Your tax advisor gets finished EXTF booking records, not just a folder of PDFs. Revenue, payments, fees and payouts are already matched, and every invoice booking carries a Beleglink to its document image in the "Belegtransfer" package for Unternehmen online.

EXTF bookings for SKR03 and SKR04
Document image attached to the booking via Beleglink
Fees and payouts already matched
Your tax advisor downloads them directly

Switching in three steps

1
Bring your data over

Orders and payments from your connected sources are pulled in, and your invoice number sequence continues. Old documents stay available in your previous system; Rechnungskit doesn't import invoices created elsewhere.

2
Test in parallel

Both systems run side by side for one billing period. You compare documents and bookings before anything goes live.

3
Switch over

Sending is switched over and your tax advisor gets the new export access. The old system stays in place as an archive.

FAQ

No. Rechnungskit creates legally compliant invoices from your transactions and hands finished bookings to DATEV. Full accounting with cash-basis accounts (EÜR) and VAT returns (UStVA) stays with your accounting tool or your tax advisor.

Yes, and that's the usual way to switch. You run both systems in parallel for one billing period and compare documents and bookings before you switch over.

They stay where they are. Rechnungskit doesn't import or archive invoices created elsewhere; you keep meeting your retention duty for old documents (eight years under § 14b (1) UStG and § 147 (3) AO) in your previous system. What Rechnungskit can pull in are past orders and payments from your connected shops and payment providers, which then become new, validated invoices. For the number sequence, you set the number Rechnungskit continues from, so nothing overlaps with your old documents.

Documents are stored tamper-proof and unchangeable for eight years for as long as your account exists (WORM archive with checksums). Eight years is the retention period for invoices and accounting records (§ 14b (1) UStG, § 147 (3) AO); the requirements for the archive are set out in the GoBD. You can export them at any time, and for 90 days free of charge after you cancel. The final assessment of your process documentation (Verfahrensdokumentation) is up to your tax advisor.

No. Rechnungskit prepares the OSS data (destination-country rates, quarterly export, monitoring of the €10,000 threshold); filing the return is done by your tax advisor or a compliance provider. Taxdoo itself has not offered the filings since 30.04.2026 either.

From the providers' publicly available sources, checked on July 28, 2026, with footnotes for each row. Where we found no reliable source, the table says "Not documented". If you spot a mistake, write to support@rechnungskit.de and we'll correct it and re-date the page.

More comparisons

Rechnungskit is not a tax advisory or law firm. This article explains general principles and does not replace advice from a tax advisor (Steuerberater, § 5 StBerG) or a lawyer (§ 3 RDG). Rechnungskit is built for businesses based in Germany and prepares documents, tax rates and bookings automatically. How your specific case is treated remains your decision, ideally together with your tax advisor or a lawyer.
