How validation works

VIES validation as part of your workflow

VIES isn't always available. Invoxo handles three states clearly: valid, invalid, and service unavailable—with easy re-checking when needed.

When VIES responds

Result saved with timestamp

Available for all future invoices.

When VIES is down

Keep last known status

Re-check later without blocking your work.

Validation evidence you can show your accountant

When questions come up—from your accountant or tax authority—you'll have proof of when the VAT number was validated and what the result was.

How it works

Client VAT ID → VIES check → Save result → Apply VAT treatment

Key benefit

VIES downtime won't block your invoicing.

Automatic, not manual

No more copying VAT numbers into the EU VIES website. Add a client and Invoxo validates their VAT ID automatically.

Works even when VIES is down

VIES isn't always available. If it's down, you can continue working and Invoxo will re-check when the service returns.

Evidence for your records

Every validation is saved with a timestamp. Show your accountant or tax authority exactly when the check was done.

How it works

Add your client once. Invoxo validates their VAT ID automatically and keeps the result for all future invoices.

1) Add your client

Enter their country and EU VAT number. Invoxo formats it correctly and stores it for future invoices.

  • ✅ Automatic formatting
  • ✅ Saved for all future invoices

2) Automatic VIES validation

Invoxo checks the VAT number against the official EU VIES service automatically. If VIES is down, you can continue and re-check later.

Every validation is saved with a timestamp. When questions come up later, you'll have proof of what was checked and when.

Why VIES validation is always included

Too important to lock behind upgrades

VAT number validation is fundamental to correct EU invoicing. That's why it's included on every plan, not reserved for premium tiers.

Handles real-world VIES downtime

VIES isn't always available. Invoxo lets you continue working and automatically re-checks when the service returns.

Evidence your accountant will appreciate

When your accountant asks "did you check this VAT number?", you'll have timestamped proof that you did.

Professional invoicing, not accounting software

Focused on what you need: compliant invoices and clean exports. Bookkeeping stays with your accountant.

VIES – Common questions

What is VIES? ⌄
VIES (VAT Information Exchange System) is the official EU service for verifying whether a VAT number is valid. It's what you'd use to check a client's VAT number before invoicing them.
Do I need to validate VAT numbers manually? ⌄
Not with Invoxo. When you add a client with an EU VAT number, Invoxo validates it automatically via VIES. No copying and pasting into the EU website.
What if VIES is down when I need to validate? ⌄
You can continue working. Invoxo will show that VIES is unavailable and let you re-check later. The last known validation result is preserved.
Does a valid VAT number mean I should use reverse charge? ⌄
Usually, yes—for cross-border EU B2B services. When a client has a valid EU VAT ID in another country, Invoxo auto-suggests reverse charge.
Why does Invoxo save validation results? ⌄
So you have evidence for your records. If your accountant or tax authority asks when you validated a VAT number, you'll have proof with a timestamp.

Disclaimer: Invoxo supports common EU VAT workflows. For complex scenarios, confirm requirements with your accountant.
