GoodVat

Global e-commerce has a fundamental compliance problem. If you sell anything cross-border, you are immediately thrust into a labyrinth of more than 14,000 perpetually changing tax jurisdictions. From shifting digital goods VAT thresholds in Europe to incredibly complex sales tax layers in the United States, keeping up with global tax law is an operational nightmare that distracts merchants from their core business.

GoodVat is a modern, developer-first global tax calculation engine built to solve this exact problem. Designed specifically for cross-border merchants, Merchant of Record (MoR) systems, and Payment Service Providers (PSPs), GoodVat completely abstracts away the friction and fear of international tax compliance.

Historically, this critical infrastructure has been dominated by two extremes: ancient legacy incumbents running on outdated architecture, or overhyped VC-backed startups that price out the independent businesses that need them most. The result is a market full of unhappy customers forced to overpay for fragile software or risk severe audit liabilities. GoodVat was built to be the clear alternative - highly accurate, effortlessly composable, and fairly priced.

The underlying difficulty in tax calculation isn’t just looking up a rate in a database; it is a hyper-local geographic problem. In the US alone, a single street address can sit inside overlapping layers of state tax, county tax, municipal tax, and special-purpose districts like transit, school, or fire departments. A standard ZIP-code-based lookup is dangerously inaccurate, frequently returning the same tax rate for two houses that sit in entirely different tax zones.
