Nigeria FIRS e-Invoice
Nigeria FIRS e-invoicing for Odoo: build the FIRSMBS document (UBL/BIS 3.0), validate it, and submit for pre-clearance with your own credentials (BYOK) to obtain the IRN and CSID.
Build the FIRSMBS document (UBL / Peppol BIS 3.0) from your customer invoices, validate it, and submit for pre-clearance with your own credentials (BYOK) to obtain the IRN and CSID. Built on account, no Enterprise dependency.
Key Features
FIRS Document on the Invoice
Build the FIRSMBS document from any customer invoice; review the JSON, the content hash, and the assigned IRN / CSID after clearance.
BYOK FIRSMBS Credentials
Configure your TIN, business ID, Service ID and your own FIRSMBS base URL, client ID and secret — nothing is shared or hard-coded.
IRN in the FIRS Format
Builds the Invoice Reference Number in the documented FIRS/NRS format InvoiceNumber-ServiceID-YYYYMMDD, provisionally on your side and confirmed by the platform on clearance.
Scannable QR Code
Generates a real, scannable QR carrying the invoice verification payload — IRN, supplier TIN, invoice number, date, currency, VAT, total and the SHA-256 content hash.
Dynamic Currency
The document currency follows the invoice currency (NGN by default), so foreign-currency invoices report the correct currency code.
Query & Cancel
Query the clearance status of a submitted invoice by IRN, and request cancellation of a cleared invoice with a reason — all with your own credentials.
Batch Pre-clearance
Group customer invoices into a batch, build them all and submit them together, tracking the assigned IRN per invoice.

Why Choose This Module
Nigeria's national e-invoicing platform (the FIRS Merchant-Buyer Solution / Electronic Fiscal System) is being mandated in phases: large taxpayers (turnover above NGN 5bn) went live in November 2025 with enforcement from April 2026, medium taxpayers (NGN 1bn–5bn) from 1 July 2026, and emerging taxpayers from 1 July 2027. This module turns Odoo customer invoices into the platform document (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 credentials — returning the assigned IRN and CSID. It also supports batch pre-clearance and B2C reporting.
