Why Choose This Module
Nigeria's FIRS Merchant-Buyer Solution (FIRSMBS) e-invoicing is mandatory for large taxpayers from November 2025 and for all VAT-registered businesses from January 2026. This module turns Odoo customer invoices into FIRSMBS documents (aligned with Peppol BIS Billing 3.0 / UBL): supplier and buyer parties with their TINs, invoice lines with quantity, discount and VAT 7.5%, the tax summary and legal monetary totals. It validates the mandatory fields and the line/tax/total math, produces both a JSON document and a UBL XML representation with a SHA-256 content hash, and submits for B2B/B2G pre-clearance using your own FIRSMBS credentials â returning the assigned IRN and CSID. It also supports batch pre-clearance and B2C reporting.
