Belgium Peppol accountant handover checklist for SMEs: access, VAT data, supplier invoices, approvals, archive, software demos and 2026 B2B readiness.
Belgium’s structured B2B e-invoicing move makes the accounting process more data-driven. The practical risk for SMEs is not only choosing a Peppol-enabled tool; it is choosing a workflow that the accountant can actually access, book, correct and audit without manual PDF workarounds.
Use this page if you are asking ‘what should I ask my accountant about Peppol?’, ‘how do I prepare my bookkeeping for Belgian e-invoicing?’, ‘can my accountant receive Peppol invoices?’ or ‘what should a software demo prove before 2026 B2B e-invoicing?’
Name an owner for outgoing invoices, incoming supplier invoices, VAT master data, Peppol registration, rejected documents, accounting export, archive evidence and month-end cut-off. A small company can use one person for several roles, but each role still needs a named owner.
Clean Belgian VAT numbers, legal names, KBO/BCE company identifiers, billing addresses, customer/supplier categories, purchase order references, VAT rates, exemption reasons, payment terms and credit note links. Structured invoices expose weak master data faster than PDF email workflows.
Ask the provider to show Peppol send and receive, Peppol BIS Billing 3.0 / EN 16931 validation, status responses, rejection messages, supplier invoice approval, accountant permissions, searchable archive, export to bookkeeping, user rights and price changes for invoice volume.
Test one normal B2B sales invoice, one supplier invoice received through Peppol, one credit note, one invoice with a wrong VAT or company identifier, one approval before booking, one archive search and one export into the accountant’s system. Use the same pack for every shortlisted tool.
Do not assume that a PDF copy sent by email keeps the accountant covered. Do not let software registration happen without deciding who monitors incoming invoices. Do not forget supplier invoices, approval rights, rejections, accountant access, pricing and archive retrieval.
Prefer a workflow that gives the accountant controlled access, clear status evidence, readable error messages, data correction rules, reliable archive/search, support in your working language and a documented fallback if an invoice is rejected or sent to the wrong Peppol recipient.
Book a 30-minute Peppol handover call with your accountant. Bring your current invoicing tool, invoice volume, supplier process, VAT data quality issues, preferred software shortlist and two real anonymised invoice examples. Capture decisions in a one-page readiness register.

Ask whether the accountant can access your sent and received invoices, which software or export they prefer, how supplier invoices will be approved, who fixes rejections, and what evidence they need for VAT review and archive checks.
No. Sending is only one part. Receiving supplier invoices, approval, booking, corrections, archive, VAT data quality and accountant access are often where day-to-day problems appear.
Sometimes, but the company still needs clear ownership for invoice creation, customer data, approvals and error correction. A fully accountant-led setup should still be tested with real examples.
Start with Belgian VAT numbers, legal names, KBO/BCE identifiers, addresses, customer and supplier records, VAT rates, exemption reasons and contact owners for invoice issues.
A useful demo should show a sent B2B invoice, a received supplier invoice, a credit note, an invalid data case, a rejection message, archive search and an export or booking handoff for the accountant.
Yes. Even a simple setup needs someone to receive supplier invoices, check VAT data, store evidence and handle rejected or misrouted documents.
A PDF may help humans read the invoice, but Belgian structured e-invoicing readiness should be based on structured invoice data, Peppol routing, validation status and archive evidence.
No. This is practical readiness guidance. Confirm exact obligations, VAT treatment and retention requirements with official sources and qualified advisers for your situation.
