peppol_idsAbout
EU E-Invoice Builder turns plain invoice data (parties, lines, VAT categories, payment means) into a Peppol BIS Billing 3.0 UBL Invoice or Credit Note XML draft. build_ubl_invoice and build_ubl_credit_note compute the totals and the VAT breakdown with the EN 16931 rounding rules, insert the CustomizationID and ProfileID, refuse input that breaks a business rule (rule ids such as BR-CO-15 or BR-AE-02 are quoted) and return the XML with a structural check. compute_totals returns line, tax and payable totals with the rounding policy stated. pick_vat_category lists what EN 16931 requires for each VAT category code (standard, zero, exempt, reverse charge, intra-community supply, export, not subject to VAT), with the exemption reason (VATEX) codes it takes, and list_vatex_codes searches the VATEX list of the May 2026 Peppol release. invoice_input_guide shows the JSON shape with a worked example and business-term numbers, and peppol_ids returns the identifiers to insert. The output is a draft for review: nothing is sent, signed or stored, national CIUS (XRechnung, Factur-X, FatturaPA) differ, and the category choice is the issuer's decision to confirm with an adviser.
