Cross-Border EU Service Invoicing Complete Guide

For B2B services across EU borders, VAT is due in the client's country and the reverse-charge mechanism applies: you don't charge VAT on the invoice; the client self-accounts. Required invoice content: your VAT number, the client's VAT number, and the statement "Reverse charge — VAT to be accounted for by the recipient." Submit EC Sales List (VIES) reporting periodically. B2C digital services to EU consumers require OSS registration once cross-border B2C sales exceed €10,000. Use the ECB reference rate for currency conversion on cross-border invoices. Get country-specific tax advice for significant cross-border engagements. Track all cross-border revenue separately in your financial dashboard.
