ShipVAT vs Vatstack

ShipVAT provides an API for calculating VAT, sales tax, and GST across 93 jurisdictions. The maker lists the EU, UK, US, Canada, and Australia among supported regions, and describes economic nexus threshold intelligence for all 50 US states and beyond. API functions include tax calculations, rate and threshold lookup, transaction and customer management, VAT validation, compliance reports, webhooks, and address validation. ShipVAT says rates include a source URL, verification timestamp, and effective dates, with tax data curated from official sources. Developers can use a TypeScript SDK, OpenAPI 3.0, Swagger UI, and curl examples. Endpoints use Bearer-token authentication with test and live key formats. The API is described as working with Paddle, LemonSqueezy, PayPal, or any payment stack. The Free plan costs nothing and allows 100 API calls per month. Pro costs $49 a month for 50,000 calls; Enterprise pricing is custom and its listed call limit is unlimited.

Vatstack is a VAT API for businesses selling telecommunications, broadcasting and electronic services to customers around the world. It provides rates for domestic and cross-border sales, updating them when government changes take effect. The API can calculate VAT-inclusive or VAT-exclusive prices, determine customer location from an IP address or billing address, verify VAT numbers for exemption, and adjust rates for some digital products such as ebooks. Real-time VAT and GST checks cover the 27 EU member states, Australia, Norway, Singapore, Switzerland and the United Kingdom. EU and UK checks include a consultation number, and validation records are stored in the cloud and replicated between EU data centers on AWS. Users can import a CSV for bulk checks. Vatstack compiles VAT OSS and EC Sales List reports using European Central Bank exchange rates, and integrates with Stripe to sync invoices, location evidence and tax IDs and to adjust reports after refunds. A free plan is available; paid plans start at $15/mo.
