What countX does
countX GmbH is a Berlin-based SaaS provider of automated VAT compliance software for e-commerce merchants selling across the European Union, the United Kingdom, and Switzerland. Founded in 2020, the company operates a platform-plus-modules architecture anchored on the countX Core Platform (app.countx.com), which reads client sales and transaction data via API from connected marketplaces (Amazon, eBay, AliExpress) and ERP/invoicing systems (JTL, Billbee, easybill, JERA), standardizes and enriches the data with applicable VAT rates, and produces compliant VAT filings including document-based (belegbasierte) returns. Service modules cover One-Stop-Shop (OSS) and Import One-Stop-Shop filings, local VAT returns across all EU countries, VAT ID registration in up to 16 European countries (including PAN-EU and CEE), Intrastat reporting, pro forma invoices for stock transfers, and DATEV export for German accounting integration. Free top-of-funnel tools (Amazon FBA Calculator, VAT ID Checker, Setup Check) feed a conversion funnel into paid plans.
The company sells through three pricing tiers — Free (€0/month), Core (from €39/month), and Professional (from €89/month, scaling up to €379/month at 25,000+ transactions) — plus per-country VAT filings at €89/month and one-time VAT ID registration at €499/country (included free in Professional). Go-to-market combines direct sales with personalized consultation, self-serve PLG via the free plan, and an extensive partner ecosystem spanning JTL (flagship ERP partner), tax advisors (Steuerberater) with a dedicated certification program, and fulfillment/invoicing integrations (Monta, Zenfulfillment, Chargecloud, FulfillmentPlus, SMARTLA, Billbee, easybill). Each Professional customer is assigned a dedicated personal VAT expert, with access to an EU tax advisor network. The company reports 600+ merchants served, operations in 16 European countries, secondary offices in Bochum (Germany) and Kyiv (Ukraine), and recognition including the K5 Commerce Award 2024 and OMR Reviews Leader (VAT Compliance Q4/25). Funding history shows a single April 2022 seed round with D4 Ventures, FJ Labs, and Inovexus; no follow-on or revenue figures are disclosed.

countX competitors and assessment
Company assessmentRegional players
- Marosa: Marosa is a Belgium-based VAT compliance and filing specialist focused on European e-commerce and cross-border merchants. It competes with countX in the same multi-country VAT filing niche with a comparable SMB/mid-market profile.
Direct peers
- Avalara: Avalara is a global tax compliance automation platform covering VAT, sales tax, and related filings. countX customers explicitly cite prior use of Avalara before migrating, making it a direct competitor in European VAT compliance for e-commerce.
- TaxJar: TaxJar (now part of Stripe) is an SMB-focused sales tax and VAT automation SaaS for online sellers. It targets a similar merchant profile to countX (Amazon, Shopify, eBay sellers) and competes for cross-border tax filings.
- Taxdoo: Taxdoo is a Hamburg-based VAT compliance SaaS for e-commerce merchants selling across the EU. A countX customer (Dirk Hemming) explicitly references migrating from Taxdoo, making it one of the closest direct competitors in the DACH e-commerce VAT space.
- Quaderno: Quaderno (acquired by Avalara) provides automated tax calculation and compliance for digital and e-commerce businesses, including VAT. It serves a similar SMB and SaaS merchant base with comparable product surface area to countX.
- Taxamo: Taxamo is a cross-border VAT and digital tax compliance platform serving marketplaces, SaaS, and e-commerce merchants. It overlaps with countX on EU VAT registration, OSS, and filing services for online sellers.
Broad incumbents
- Sovos: Sovos provides global indirect tax compliance software, including VAT filings and e-invoicing. It serves multinational and mid-market customers and overlaps with countX's VAT filing and registration capabilities, albeit at a much larger enterprise scale.
- Vertex: Vertex is a large, established tax technology provider with VAT and indirect tax compliance offerings. While broader in scope (enterprise and global), it competes for the same VAT compliance wallet of cross-border merchants countX serves.
- Stripe Tax: Stripe Tax is a tax compliance add-on within Stripe's payments platform, calculating and filing sales tax and VAT for online sellers. It targets the same SMB e-commerce merchant base as countX but bundles tax into a payments platform, posing a competitive threat via distribution scale.
Emerging players
- Fonoa: Fonoa is an API-first tax compliance platform offering VAT registration, calculation, and filing for digital businesses and marketplaces. It targets a similar cross-border e-commerce use case as countX but with a developer-focused, integration-first product posture.

Does countX have an API?
Yes. countX reads client sales data from systems or accounts via API connections to automate VAT compliance. Clients provide API Access Credentials (uniquely identifying credentials) for the company to retrieve transaction data, invoice data, and other information from the client's connected Marketplaces. The company uses obtained API data in the same manner as data directly provided by the client. For non-marketplace transactions, clients provide data through the website or as countX template files. The company states it has no obligation to verify data completeness or accuracy — the client is solely responsible for providing accurate data. No public developer portal or REST/GraphQL API documentation was identified; integration is described as a data-read mechanism controlled by countX, not a customer-facing API.
