Start with your accountant
For many Belgian SMEs, the accountant will shape the practical software path. Confirm whether your current tools will support structured invoice exchange.

What you need to know
Test both send and receive
Readiness is not just issuing invoices. Receiving, approving, archiving and booking supplier invoices also matters.
Prepare customer data
Structured invoicing depends on accurate VAT numbers, legal names, addresses and routing identifiers.
SME preparation order
Start with the accountant, then the software provider, then customer/supplier data cleanup. This order reduces the risk of choosing a workflow the accountant cannot support.
What to test
Test outgoing invoices, incoming supplier invoices, VAT data, archive/search and user permissions. Include the person who actually books invoices every month.
Search-intent summary
Belgian SMEs usually ask what Peppol is, whether their accounting software supports it, whether freelancers are affected, how to receive supplier invoices, what their accountant recommends and which VAT/customer data needs cleaning.
Decision framework for SMEs
A good Belgian e-invoicing setup should support both sending and receiving, fit the accountant’s workflow, handle customer and supplier master data, offer clear pricing and make archive/search simple for everyday bookkeeping.
Implementation plan for small teams
Assign one person to coordinate the accountant, software provider and internal invoice users. Prepare customer and supplier records, test one outgoing invoice and one incoming supplier invoice, then document the final workflow so replacements or new staff can follow it without improvising.
Checklist
