What is Peppol?
Peppol (Pan-European Public Procurement Online) is an international network for electronic invoicing and document exchange. From January 1, 2026, B2B e-invoicing via Peppol becomes mandatory in Belgium.
Why does this matter for your business?
Businesses that sell time and expertise often send hundreds of invoices per month to various clients. The shift to Peppol means:
Standardized invoicing: All invoices must comply with the UBL format
Automatic validation: Invoices are automatically checked for correctness
Faster processing: Clients receive and process invoices faster
Compliance required: Non-compliance can lead to fines and client issues
Why generic tools fall short
Many resource-driven businesses still use Excel or generic ERP systems. These tools aren't built for that complexity:
Multiple rates per person: Hourly rate, overtime, expense reimbursements
Variable invoicing: Per hour, per day, per project
Complex time registration: Approval flows, corrections, split billing
