All businesses must be able to receive electronic invoices as of September 1, 2026. The requirement to issue electronic invoices will be phased in based on the businesses’ size.

Calendar. Effective September 1, 2026, all affected companies must be able to receive electronic invoices. Large companies and mid-sized companies must also begin issuing electronic invoices by that date; small and medium-sized enterprises (SMEs) and microenterprises will transition to issuing electronic invoices on September 1, 2027.

Eligibility: All affected companies starting in September 2026

Don't reduce the project to a choice of software

The reform affects billing, accounts receivable, accounts payable, VAT, controls, and data management. It should be treated as a process-oriented project rather than a simple technical implementation.

Checkpoints

  • completeness of the invoices received;
  • rejection and status management;
  • consistency between the invoice, the order, and the payment;
  • processing of credits and down payments;
  • archiving and access to documents;
  • Reconciliation with accounting records and tax returns.

FAQ

Is a PDF invoice sent by email sufficient?

The reform calls for data exchange through the designated system and platforms, using structured data formats. A simple PDF sent by email does not, on its own, constitute the target process.

Will small businesses be affected starting in 2026?

Yes, regarding receipt. The obligation to issue it generally takes effect on September 1, 2027.

When Should You Choose a Platform?

The decision must be made early enough to configure the system, ensure data reliability, test data flows, and train users before the deadline.
