The 2026 PEPPOL mandate applies to every Belgian VAT-registered business, regardless of size. That's a good thing in principle — a single standard, less paperwork, faster payments. In practice, the transition can feel heavier than it needs to be, especially for a small team already juggling operations, accounting, and clients.
This guide is for Belgian SMEs — 1 to 20 employees — that want the shortest path from "we don't do e-invoicing" to "PEPPOL works, we forget about it".
What matters most in April 2026
Two obligations, both non-negotiable:
- You must be able to receive PEPPOL e-invoices from your suppliers.
- You must be able to send PEPPOL e-invoices to Belgian B2B customers who request them (which, in practice, will be most of them).
Everything else (structured formats, retention, VAT calculation) already exists in Belgian law. PEPPOL is the transport layer being made mandatory.
Three real-world SME situations
Situation A: Family bakery, 4 employees
They issue 15–25 invoices monthly, mostly B2B (Horeca clients, event caterers). They already use accounting software but no e-invoicing. What they need: switch on PEPPOL sending, keep their existing accountant workflow, don't retrain staff. DEMFACT slot: Essentials subscription (€19.99/month), integrated with their accountant via the accountant portal.
Situation B: Solo consultant, 0 employees
They issue 3–8 invoices monthly, high value, mostly to large Belgian clients. They don't need a full accounting suite. What they need: send PEPPOL cleanly, get paid faster, spend zero time on invoicing admin. DEMFACT slot: Pay As You Go (€2 per invoice, no subscription).
Situation C: Construction company, 12 employees
They issue 60+ invoices monthly, mostly with reverse-charge VAT (art. 20). Delivery must be reliable — a missed invoice means a missed payment cycle. What they need: bulk sending, reverse-charge auto-applied, reliable PEPPOL delivery, real-time visibility for the office manager. DEMFACT slot: Professional subscription.
What "simple" actually means for an SME
Simple isn't the same as few features. For an SME, simple means:
- Setup once, works forever — no reconfiguration each month
- VAT rules that fit Belgium — no need to manually flag reverse-charge
- Support that answers in your language (NL or FR) within a reasonable time
- Clear pricing — you know exactly what a month costs before it starts
- An accountant portal — so your bookkeeper works directly on your data, without emailing PDFs back and forth
How DEMFACT is built for this
DEMFACT was designed for Belgian VAT-registered businesses, not adapted from a generic international tool. That shows in five concrete places:
- VAT logic — 21/12/6/0%, art. 20 construction reverse-charge, B2B EU reverse-charge, all applied automatically based on client and product.
- PEPPOL identifier auto-generation — the format 0208:BE + VAT is generated correctly the first time.
- KBO/VIES integration — client data auto-filled from the Belgian company registry and EU VIES.
- Structured Communication — Belgian +++/+++ payment references generated on request, valid modulo 97.
- Accountant portal — your bookkeeper gets real-time access to your invoices, no export/import loop.
The 30-day test
The best way to know if PEPPOL invoicing software works for your SME is to send real invoices through it for 30 days. On DEMFACT, that costs €6–€30 total on Pay As You Go — you send actual invoices to actual clients, in production, no sandbox theatre. If it works, you keep going. If it doesn't, you paid less than one restaurant lunch to find out.
