Vatify

EU VAT validation, rates, and calculation in 3 endpoints.

Open

EU VAT is a tax trap that turns simple checkout code into a compliance mess. Vatify gives developers a tiny API surface to validate VAT IDs, pull the right country rates, and calculate VAT correctly. You ship faster, charge the right tax, and stop guessing when finance asks “why is this invoice wrong?”

VAT bugs don’t show up in staging. They show up in chargebacks.

Most SaaS teams treat EU VAT like a “later” problem.

Then the first B2B customer asks for a VAT invoice, your checkout collects the wrong tax, and you’re stuck hand-auditing orders in a spreadsheet at 1 a.m. Brutal.

Vatifytax.app goes after the boring parts that break revenue: VAT ID checks, current VAT rates, and VAT math.

The product: three endpoints, no drama

Vatify keeps the surface area small:

  • /v1/validate-vat: validate a VAT ID against official sources, with stable JSON responses you can trust in backend code.
  • /v1/rates/{country}: fetch standard and reduced rates with date reference so you don’t hardcode rates that go stale.
  • /v1/calculate: compute VAT for an order using a standard rate or a category hint.

That’s it. No “platform”. No maze of services.

Developer experience that respects your time

You authenticate with a simple Bearer token.

Responses come back as JSON by default, with clear error messages and sensible status codes. The docs lean on copy-paste snippets (cURL and fetch), so you can get a working request into your app fast instead of spending a day “integrating”.

And if you live in Python, there’s an official SDK on PyPI. Install, set your key, call validate. Done.

Speed + pricing that won’t surprise you

Vatifytax.app claims typical response times under 200ms in the EU region. That matters when validation sits in the checkout path and every extra hop costs you conversions.

Pricing stays simple:

  • Free tier: 30 requests/month for testing.
  • Pro: €9/month for 1,000 requests with higher limits and email support.

Cancel anytime. No call. No procurement theater.

Who it’s for

If you sell to EU customers, run B2B invoices, or need to decide when to charge VAT, this fits.

Especially if you’re a small team and you want tax logic to stop hijacking your roadmap.

Ship the feature. Charge the right tax. Sleep.

Frequently Asked Questions

How to validate an EU VAT number during checkout without slowing down payments?
Use api.vatifytax.app to validate the VAT ID with a single call to the /v1/validate-vat endpoint, then cache the result on the customer record so you don’t re-check on every payment. Keep the request server-side, set a short timeout, and fail gracefully (collect VAT) if the validation service can’t respond.
