E-Invoicing

E-Invoicing turns InvoiceShelf invoices into EN 16931 e-invoices. With it switched on, an invoice PDF becomes a ZUGFeRD / Factur-X hybrid: a PDF/A-3b document people read as usual, carrying the structured XML that accounting software reads as factur-x.xml.

The XML follows the EN 16931 profile, which German businesses accept as an e-invoice and which is one of the formats France's e-invoicing reform allows. The same XML can be downloaded on its own from every invoice.

Settings live under Company Settings, E-Invoicing: switch it on, give the IBAN and BIC the e-invoice asks to be paid to, and payment terms. A checklist shows what the company details still lack, such as a VAT ID or a postal address.

Every invoice shows a panel that says whether its PDF carries the XML and, if not, exactly what is missing. Tax types carry their EN 16931 category (standard, zero rated, exempt with a reason, export, reverse charge and intra-community supply) and units their UN/ECE code, both set in InvoiceShelf itself. Credit notes are written as credit notes that name the invoice they correct.

Every way an invoice leaves InvoiceShelf carries the same file: download, public link, customer portal, email attachment and the PDF archive. Nothing gets in the way of billing: an invoice that does not meet the requirements, or a PDF service that cannot embed the XML, gets the ordinary PDF.

The module creates and embeds the e-invoice; it does not send it anywhere. Embedding needs InvoiceShelf's Gotenberg PDF driver with Gotenberg 8.34 or newer (the full image, with LibreOffice). Downloading the XML works with any PDF driver.
