Brev

What it does

JVM library that writes and reads Peppol BIS Billing 3.0 invoices and credit notes as UBL 2.1 XML from a typed model, with Norwegian supplier identifiers, six VAT categories and attachments. It needs JDK 27, with no third-party dependencies; SMP lookup and access-point messages are types only. The README warns to keep official PHIVE validation on the send path until its own rules match.
