This is what an extension card looks like above the page you're working on. A demo, not real data.

What are you doing manually today

Delivering to another EU country without VAT depends on the buyer’s valid VAT number. If the number is invalid and you don’t detect it, you’ll have to pay the VAT yourself. VIES verifies it but doesn’t store anything, so during an audit, you must prove you checked it on the invoice date.

What the extension can do

  • Highlight the VAT number on an invoice, order, or email, and the extension verifies it in VIES.
  • Proof storage: date, time, and verification ID from the European Commission, recognised by tax authorities.
  • Buyer monitoring: We check VAT numbers you add weekly and email you if they’re cancelled.
  • Bulk checks from a spreadsheet before month-end.
  • Supports all 27 EU countries, plus Switzerland and Norway (via their registries).
  • If VIES is down (common for some countries), the extension alerts you and retries automatically.

Frequently asked questions

How is it different from free VIES?

VIES verifies but doesn’t store anything, lacks bulk checks or monitoring. We add memory, monitoring, and speed—you can verify without leaving the invoice.

Does the tax office accept your proof?

We store the official verification ID (consultation number) issued by the European Commission—that’s exactly what authorities require.

When will it launch and what if the date changes?

We're planning October 2026. We build in order of interest, so the launch date can shift by a month either way. Those who leave their email get a message on launch day.
