In Cameroon, an invoice is not just a receipt. It is a tax document: it justifies a sale, opens (or not) a VAT deduction right for your customer, and serves as evidence during an audit by the tax authority (DGI). An incomplete invoice means a risk of tax adjustment for you and an unhappy customer. Here is how to issue clean, compliant invoices that are ready for the standardized-invoicing reform.

What the law expects from an invoice

Whatever your sector, an invoice issued by a business must unambiguously identify the seller, the buyer and the transaction. In practice, it contains:

The seller's identity: business name, address, NIU (Unique Identification Number issued by the DGI) and RCCM registration number.
The customer's identity: name or business name, and their NIU when they are a professional.
A unique, sequential invoice number and the issue date.
A breakdown of goods or services: description, quantity, unit price excluding tax.
The amount excluding tax, the VAT rate and amount, then the total including tax.
The currency (FCFA/XAF) and, where relevant, the payment terms.

The NIU is the linchpin: it is mandatory on every invoice and every filing. Without it, your document has no tax value.

VAT: only charge it if you are entitled to

Only businesses under the real regime collect VAT at 19.25%. Below the corresponding turnover threshold, you do not charge VAT and you cannot deduct it on your purchases. Showing VAT on an invoice when you are not liable exposes you to having to remit it in full, with no deduction right.

The standardized-invoicing reform

The DGI is progressively rolling out a standardized invoicing system (a secured invoice, often carrying a QR code or a verifiable identifier). The goal is clear: improve transaction traceability, secure VAT and broaden the tax base. The rollout happens in waves — large companies first, then a gradual extension to SMEs — and the technical details (formats, transmission) are published as they are finalized.

The message for an SME is simple: get ahead of it. A business that already issues digital, numbered invoices with every mandatory field and a verifiable identifier will have almost nothing to change the day the obligation reaches it. The one still writing carbon-copy invoices by hand will have to rebuild everything under pressure.

The mistakes that cost you

Inconsistent numbering: repeated or skipped numbers draw attention during an audit.
Missing NIU (yours or your professional customer's).
VAT charged wrongly by a non-liable business.
Invoices you can't find: a lost book or an overwritten file and you can no longer justify a sale.
No copy kept: you must retain a copy of every invoice issued.

Invoice correctly, without thinking about it

That is exactly what NexaCore automates. The software issues compliant invoices in FCFA, carries your NIU and RCCM, computes 19.25% VAT line by line, numbers each document automatically and archives it durably. Every invoice already carries a verifiable standardized-invoice QR code, and payment tracking (cash, transfer, MTN Mobile Money, Orange Money) is tied to the matching invoice — your SYSCOHADA accounting updates itself.

In short: get your mandatory fields right, only charge VAT if you are liable, and adopt a digital invoicing tool now. The day standardized invoicing becomes mandatory for your SME, you will already be ready.
