How it works
Invoice numbering must be sequential and non-repeating within the business, and the required fields depend partly on the transaction type, such as domestic, cross-border or reverse-charge supplies. Electronic invoicing requirements are being phased in for business-to-business transactions under a defined timetable set in law.
Commonly mixed up with
Simplified receipts for small amounts are sometimes assumed to meet full invoice requirements. Small-value receipts follow a reduced set of rules that do not apply automatically to larger invoices.
