Frequently asked questions
What is a simplified invoice?
Most EU countries allow a simplified invoice for sales up to €100 (or €400 in some countries) without the customer's details and with less detail about VAT.
How long must I keep invoices?
Retention periods are set nationally — commonly 6 to 10 years (for example 10 years in Germany and 6 in the UK).
When is e-invoicing mandatory?
It's rolling out: Belgium (B2B from January 2026), Poland (KSeF from February 2026), Croatia (January 2026), France (receiving from September 2026, issuing by size 2026–2027) and Germany (receiving since 2025, issuing from 2027–2028). The EU ViDA package makes e-invoicing standard for cross-border B2B from July 2030.
