The verdict in three sentences
In 2026, e-invoicing reform requires B2B e-commerce merchants to issue and receive invoices through an accredited platform (PDP/Peppol access point). Compliance costs EUR 5,000-20,000 over 4-8 weeks depending on ERP and flow complexity. The critical point is not the Factur-X format but the integration between store, ERP and platform, plus transaction-data e-reporting.
Timeline and scope of the obligation
The obligation rolls out in stages by company size. 2026 timeline orders of magnitude:
| Stage | Who | Indicative deadline | What is mandatory |
|---|---|---|---|
| Reception | All companies | Already in force | Receive e-invoices |
| Issuance | Large + mid-cap | 2026 | Issue via platform |
| Issuance | SMEs + micro | 2027 | Issue via platform |
| E-reporting | All (B2C, cross-border) | By size | Transmit transaction data |
| Formats | All | Ongoing | Factur-X, UBL, CII/Peppol |
Preparing ahead of the deadline avoids a rush and lets you negotiate integration costs.
Per-flow cost and compliance line items
Budget depends on the number of flows (issuance, reception, e-reporting) and systems to connect.
| Item | 2026 cost | Recurrence |
|---|---|---|
| Platform subscription | EUR 0.20-0.80/invoice or flat | Recurring |
| ERP/e-commerce integration | EUR 5,000-15,000 | One-off |
| Factur-X format mapping | EUR 1,500-4,000 | One-off |
| E-reporting flow | EUR 2,000-6,000 | One-off |
| Testing and acceptance | EUR 1,000-3,000 | One-off |
| Non-compliance penalty | EUR 15/invoice (capped) | Per breach |
Penalties apply per invoice with an annual cap: anticipate rather than absorb them.

Mini case study
Thomas, CFO of a B2B wholesaler issuing 3,500 invoices/month, must comply. Platform + ERP integration: EUR 12,000, plus EUR 0.35/invoice. By automating issuance and reconciliation he removes 3 days/month of manual entry, i.e. about EUR 9,600/year saved. Payback in about 15 months, before avoiding any penalty.
FAQ
Do I need an accredited platform or is a directory enough? You must use an accredited platform to issue and receive. The choice conditions the connectors available with your ERP and CMS.
Is Factur-X the only format? No: Factur-X (hybrid PDF + XML), UBL and CII/Peppol are accepted. A good platform converts between formats for your partners.
Does e-reporting cover my B2C e-commerce? Yes: B2C and cross-border transactions fall under e-reporting even without mandatory e-invoicing. Aggregated data must be transmitted.
How much lead time before the deadline? Budget 4-8 weeks of project plus a testing period with your main customers/suppliers. Starting 3-6 months ahead is prudent.
What is the risk of delay? Per-invoice penalties and operational risk: large customers may reject non-compliant invoices, blocking your collections.
