What Taxdoo does
Taxdoo is a Hamburg-based TaxTech company founded in 2016 that provides AI-powered, real-time accounting software for e-commerce merchants and their tax advisors, primarily in Germany and across the EU. Its platform connects to 50+ marketplaces (Amazon, eBay, Kaufland), shop systems (Shopify, JTL, Afterbuy, Billbee, PlentyOne), payment providers (PayPal, Stripe, Klarna, Mollie, Amazon Pay) and banks to automatically capture every sale, fee, payment, invoice, and contract, and convert that data into GoBD-compliant bookkeeping entries, EU VAT compliance (OSS, IOSS, UStVA), and DATEV-compatible exports for German tax consultants. The company has processed approximately EUR 14.5 billion in sales across roughly 3,000 merchants.
The core product, TAXDOO Accounting, is delivered on a subscription SaaS basis with a product-led growth motion (self-serve product tour and online signup) combined with sales-assisted onboarding for mid-market and enterprise merchants. A Steuerberater (tax advisor) channel program embeds Taxdoo into the DATEV workflow of German tax consultancy firms. A TAXDOO Payroll add-on — bundled exclusively with Accounting — extends the platform into payroll processing, statutory reporting, and HR software, with Taxdoo assuming liability for payroll calculations. The product architecture follows a "Service as a Software" model in which AI generates bookings autonomously and former tax auditors review the output, with corrections feeding back into the platform.
In 2025–2026, Taxdoo executed a deliberate business-model pivot: it acquired a majority stake in KI-accounting provider accountDigital (June 2025), launched TAXDOO Payroll (April 2026), and discontinued its classic VAT compliance services and DATEV export add-on by April 30, 2026, reorienting the company around AI-powered accounting automation in anticipation of the EU VAT in the Digital Age (ViDA) directive taking effect in 2028. Reported revenue is in the EUR 10–20 million range as of March 2026, and the company has raised $84 million in total funding, including a $64 million Series B led by Tiger Global in December 2021.

Company assessmentDirect peers
- BuchhaltungsButler: German AI-automated bookkeeping SaaS for SMBs with banking integration and Steuerberater data export. Closely comparable proposition to TAXDOO Accounting.
