Frequently asked questions

These answers are also published as structured data for search and answer engines.

What is Peppol BIS 3.0? +
Peppol BIS (Business Interoperability Specifications) 3.0 is the standard that defines how business documents like invoices and credit notes are structured and exchanged on the Peppol network. It uses UBL 2.1 XML syntax with EN16931 as the underlying semantic model.
What format does GoRoute use for e-invoices? +
GoRoute uses UBL 2.1 (Universal Business Language) XML format as specified by Peppol BIS 3.0. This is the standard syntax for invoices, credit notes, orders, and catalogues exchanged on the Peppol network and mandated across the EU.
What is the AS4 transport protocol? +
AS4 (Applicability Statement 4) is the secure messaging protocol used by Peppol for document transport between Access Points. It provides reliable delivery with digital signatures, encryption, message receipts, and non-repudiation built into the protocol.
What is PINT and how is it different from BIS? +
PINT (Peppol International) is the next-generation invoice specification designed for non-European markets. While BIS 3.0 is based on EU standards (EN16931), PINT extends support for Asia-Pacific (A-NZ, JP, MY, SG) and other regions with country-specific extensions.
Where can I find UBL XML sample files? +
Sample UBL XML files for invoices, credit notes, and other document types are available in the Peppol BIS 3.0 release package on OpenPeppol's GitHub repository. GoRoute's API documentation at docs.goroute.ai also includes working examples.
