PEPPOL (Pan-European Public Procurement OnLine) is a European standard and network for exchanging structured electronic business documents — primarily invoices — between companies and public authorities.

When is it mandatory in Bulgaria?

As of 2026: voluntary for B2B; necessary for B2G, since public authorities must accept e-invoices under EU Directive 2014/55. A staged obligation for state suppliers is expected in 2027-2028.

What is the difference between PEPPOL and a regular email PDF invoice?

A PDF is a visual document — it requires manual entry. A PEPPOL invoice is a structured UBL 2.1 XML document, processed automatically by the recipient's ERP through the 4-corner network.

How much does PEPPOL integration cost?

Prices range from ~50 BGN (25.57 EUR) per month for SME packages to corporate solutions with per-document pricing. Through Fakturka.bg, PEPPOL is included in Pro / Business plans with no extra fees.

Can a small business use PEPPOL?

Yes — through invoicing platforms like Fakturka.bg that provide PEPPOL as an add-on. You don't need your own Access Point.

What is an Access Point?

A software service certified by OpenPeppol that accepts, validates and delivers PEPPOL documents. Each network participant has its own AP — sender and recipient only need to know their own.

Is the format XML or PDF?

PEPPOL is XML in UBL 2.1 with the PEPPOL BIS Billing 3.0 profile. A PDF can be attached as an annex but does not replace the structured XML.

Which EU countries are leading?

Italy (mandatory since 2019), Poland (KSeF from 2026), Germany (staged 2025-2027), Belgium (2026), the Nordics (Norway, Denmark, Sweden — for years already).

How does Fakturka.bg send PEPPOL invoices?

Through a certified European Access Point partnership. From the dashboard: open the invoice → "Send via PEPPOL" → automatic UBL 2.1 generation → routing through the recipient's AP.

What are the penalties for non-compliance (B2G)?

Currently no direct penalties for the sender in Bulgaria — there is no supplier mandate. Penalties exist for public authorities that fail to accept e-invoices under EU Directive 2014/55. After the upcoming B2G mandate, supplier penalties will be defined.
