Invoxo is the invoicing platform for service businesses that sell across EU borders. Most invoicing tools leave you to figure out VAT rules yourself. Invoxo automatically determines the correct treatment for every invoice — reverse charge, OSS, domestic — with VIES validation built in. Free tools available with no signup: VIES VAT Number Checker and VAT Decision Tool at invoxo.eu.

Hey! I built Invoxo because I was tired of Googling VAT rules every time I sent a cross-border invoice.

If you're a freelancer or run a service business in the EU, you know the pain: Is this reverse charge? Do I need to check their VAT number? What rate applies for digital services to consumers?

Invoxo answers all of that automatically. Select your client, and the VAT treatment is determined for you — with VIES validation, audit-ready records, and exports your accountant will actually appreciate.

I also built two free tools anyone can use without signing up:

VIES Checker (validate any EU VAT number)
VAT Decision Tool (figure out your tax treatment in 3 questions)

Happy to answer any questions about EU VAT — it's unfortunately my area of expertise now 😄
