vatnode is an EU VAT validation API built for developers, SaaS platforms, fintech products, e-commerce, and ERP integrators selling B2B across Europe.
Basic VAT APIs usually return only valid: true. vatnode returns a richer audit-ready validation record: VIES consultation number for qualified checks, checkId, verifiedAt, source authority, company data, and country VAT rate details in one REST response.
Use it at checkout, before invoice generation, during B2B onboarding, or as part of recurring customer VAT monitoring.
checkId + verifiedAt audit trail fieldsBuilt for teams that need more than a boolean VAT result โ they need validation evidence they can store with invoices and customer records.
Getwebstack is for development teams that implement a lot of different projects. It can help outsourcing companies, accelerators, freelancers, or dev studios to develop fast. It is also for individuals that want to test a technology or an idea for a startup with a quick setup and deployment. Getwebstack provides a complete solution that covers all the technical aspects of a web app. It has an affordable monthly subscription instead of an expensive one-time payment.

vatnode returns the official VIES consultation number for qualified checks โ a piece of evidence most commercial VAT validation APIs don't surface. Combined with checkId and verifiedAt fields in every response, it gives finance and engineering teams a defensible record they can store with each invoice. When VIES is unavailable, vatnode falls back to national tax authority APIs across multiple EU countries instead of just failing the check.

Secondary audience: accountants and tax advisors who want a reliable API behind their workflows.
VATnode.dev's answer
vatnode was built by a Finland-based former CTO with 25+ years of experience shipping B2B software, VAT-aware e-commerce, invoicing systems, and payment integrations across European markets. The recurring pattern in those projects was the same: every commercial VAT validation tool returned a boolean, but finance teams needed an actual paper trail โ the kind tax authorities expect when reviewing reverse-charge invoices. vatnode is the API that should have existed years ago: VIES consultation number, structured audit fields, national fallback, EU-hosted, developer-friendly.
