Frequently Asked Questions

Nvono is an e-invoicing and tax compliance platform built for Nigerian businesses. It helps you create, manage, and submit invoices to the FIRS MBS (Merchant Buyer Solution) system. We are a FIRS-accredited Access Point Provider (APP) and System Integrator (SI).

Any Nigerian business that needs to issue e-invoices or comply with FIRS e-invoicing requirements. This includes sole traders, SMEs, and large enterprises across all industries.

Not at all. Our web interface is designed to be intuitive. You can create and submit invoices with just a few clicks. For businesses that want to automate, we also offer a REST API.

The Merchant Buyer Solution (MBS) is the FIRS e-invoicing system that requires businesses to submit electronic invoices for tax compliance. It assigns an Invoice Reference Number (IRN) and QR code to each valid invoice.

When you finalize an invoice, Nvono generates the required UBL 2.1 XML document, validates it against FIRS rules, signs it, and submits it to the MBS system. You receive the IRN and QR code back automatically.

We support invoices, credit notes, debit notes, and bills. Each follows the correct FIRS UBL 2.1 schema. Transaction types include B2B (Business-to-Business), B2G (Business-to-Government), and B2C (Business-to-Consumer).
