Somewhere in your customer base, a business is about to get a compliance letter.
Their government is telling them they must send and receive invoices in a structured electronic format: not PDFs, not emails, not exports from accounting software. Structured data, machine-readable, transmitted over a certified network.
That network is called Peppol. And if your product touches invoicing for European B2B customers, it's about to become your problem too.
So What is Peppol?
Peppol (Pan-European Public Procurement On-Line) is a set of open standards and a global network that allows businesses to exchange electronic documents.primarily invoices.in a standardised, interoperable way.
Think of it like email, but for invoices. Any business connected to the Peppol network can send a structured invoice to any other connected business, regardless of what accounting software they use, what country they're in, or which service provider they connect through.
The Document Standard
Invoices follow the UBL 2.1 format, structured according to the EN 16931 European norm.
The Network
A four-corner model where sender and receiver each connect through their own Access Point provider.
The Directory
A lookup system (SMP/SML) that lets Access Points find each other by participant ID.
Why is It Becoming Mandatory?
The EU has been pushing e-invoicing for years through public procurement. Now that's expanding to B2B. Germany made receiving structured e-invoices mandatory for all businesses from January 2025. Belgium follows in 2026. Poland is rolling out KSeF. More countries are confirming mandates through 2027 and beyond.
Key Deadlines by Country
- 🇩🇪Germany: January 2025, mandatory for receiving B2B e-invoices
- 🇧🇪Belgium: January 2026
- 🇫🇷France: September 2026
- 🇵🇱Poland: KSeF rollout in progress
What Does This Mean for SaaS and Hosting Companies?
If your platform generates invoices for customers, or if your customers use your platform to invoice their own clients, you're in the chain. The question isn't whether Peppol affects your business. It's whether you're going to handle it proactively or wait for customers to start asking why you're not compliant.
The good news: you don't need to become a Peppol expert or build your own Access Point. Connectivity to the Peppol network is available via API.
What's an Access Point?
An Access Point (AP) is a certified gateway into the Peppol network. Building and certifying your own takes months and significant ongoing operational overhead. For most SaaS and hosting companies, connecting to an existing certified AP via API is the practical path.
