OASIS UBL

Convert GOBL to the OASIS UBL format.

Description

OASIS UBL

Developer	Invopop
Category	Format

OASIS UBL (Universal Business Language) is a royalty-free OASIS standard defining XML business documents such as purchase orders, invoices, and waybills. This app converts GOBL documents to and from UBL XML.

Key features

Output different UBL syntaxes:

• Peppol BIS v3 UBL invoice and credit note
• XRechnung UBL invoice V2.0
• EN 16931 UBL invoice and credit note

File access: by default Invopop will generate public URLs with a secure hash that can be shared with customers. If this is not desired, you can configure the action to make the file private, so it is only accessible via the API.

Actions

Generate UBL document

Import UBL document

Documents

Sample invoices demonstrating various OASIS UBL implementations across different countries and use cases.
