What it means for your cash
The mandate changes how invoices travel, not when your customers pay. Payment terms and late payment stay as they are.
Between companies in Belgium, a customer who pays late owes 10.50% a year from 1 July to 31 December 2026 (Law of 2 August 2002, art. 5). Calculate what a late customer owes you
An invoice that arrives as a structured file is faster to check, and checking is what a funder needs before it pays an invoice early.
