EU VAT Automation
for Shopify & Stripe
sellers.

QANTIV is a VAT compliance automation platform built for e-commerce sellers who trade across EU borders. It connects to your Shopify store and Stripe account, automatically calculates the correct VAT rate for each of the 27 EU member states plus the UK, monitors One-Stop Shop (OSS) registration thresholds in real time, and files VAT returns directly to HMRC through the Making Tax Digital (MTD) API. Instead of managing spreadsheets or hiring tax consultants for each jurisdiction, sellers get a single dashboard that handles everything from transaction sync to government filing.

When you connect your Shopify and Stripe accounts, QANTIV pulls every transaction — orders, refunds, and payments — and determines the applicable VAT rate based on the customer's country, the product type, and current EU VAT directives. Exchange rates are fetched daily from the European Central Bank (ECB) for EUR and the Bank of England (BoE) for GBP, ensuring multi-currency accuracy. VAT reports are generated automatically without manual data entry, and rates update every 24 hours to reflect any regulatory changes.

QANTIV supports all 27 EU member states — including Germany, France, Spain, Italy, the Netherlands, and every other EU country — for VAT calculation and OSS threshold monitoring under the EU's One-Stop Shop scheme (EU Council Directive 2017/2455). The UK is fully supported for HMRC Making Tax Digital (MTD) VAT filing. Currently, QANTIV focuses on EU and UK jurisdictions; US sales tax, Brazil, and other non-EU regions are planned for a future release.

The One-Stop Shop (OSS) is an EU VAT scheme that allows e-commerce sellers to file a single VAT return for all cross-border B2C sales within the EU, rather than registering in each country individually. However, sellers must register for OSS once their cross-border sales exceed €10,000 per year. QANTIV tracks your sales to every EU country in real time and sends alerts before you breach any threshold, so you never miss a registration deadline or face penalties for late compliance.

HMRC's Making Tax Digital (MTD) programme requires UK VAT-registered businesses to keep digital records and submit VAT returns through MTD-compatible software. QANTIV connects to the HMRC MTD API directly: after your transactions sync and VAT obligations are calculated, QANTIV generates the VAT return for your review. You check the figures, click approve, and the return is submitted electronically to HMRC. Every step — from data sync to filing — is logged in a tamper-proof audit trail for your records.

Security is built into every layer of QANTIV. All connections use TLS 1.3 encryption. Each tenant's data is isolated in a separate database schema — your data is never mixed with other users. We never store your Shopify or Stripe passwords; authentication uses OAuth 2.0, and the resulting tokens are encrypted at rest using AES-256. All API endpoints are rate-limited to prevent abuse, containers run with read-only filesystems and no privilege escalation, and automated backups are encrypted with GPG before storage.

QANTIV is free during the beta period with full access to every feature — VAT calculation, OSS monitoring, HMRC filing, multi-platform sync, and anomaly detection. After the beta, pricing starts at €49/month for a single plan that includes everything. No credit card is required to start your 14-day trial, and you can cancel at any time with no lock-in or hidden fees.
