Each jurisdiction applies their own flavors of PINT rules, code lists, and mandatory fields. Exchange-channel rejection is costly, and invoice data often cannot go to a vendor cloud without proper anonymization.

e31-MFA provides pre-flight invoice and credit note checks with remediating error codes, parsing to canonical JSON files, which can further be used to generate report-ready files, all running locally on your infrastructure.

Parse

Read and produce EN 16931-aligned, neutral JSON-files from prepared XML-files validated against JSON schemas.

Validate

Pass/fail with 301+ codes mapped to a common Verification Codes Reference (VCR) before submission.

Generate

Produce submission-ready, profile-specific XML-files from canonical JSON with a post-generate validation gate.

100% on-premises. Invoice data never leaves your environment. e31-MFA does not transmit files or hold exchange credentials.

Transport, participant registration, and ASP/FTA reporting remain with your exchange channel provider.

Who e31-MFA Serves

ERP / billing teams producing structured invoice XML or canonical JSON who need deterministic, on-premises validation, parsing, and generation before exchange-channel submission.

e31-MFA is a multi-country, multi-format adapter working off of one canonical model with licensed profiles per country.
