How to Create an Invoice in Nigeria

Creating an invoice isn't complicated once you know what goes into one and in what order. Here's the practical process, whether you're billing a client for freelance work, selling a product, or invoicing a business customer.

1. Gather your business details

Before you write anything, have these ready: your business (or trading) name, address, phone number, and email. If your business is registered, you can also include your RC number and Tax ID (TIN) — this is optional, but it signals a properly registered business, which matters more the larger or more formal your customer is.

2. Confirm the customer's details

At minimum, you need the customer's name. If you're invoicing a company, get the registered business name and an address — this is what should appear under "Billed to," not just a contact person's name.

3. Assign an invoice number

Every invoice needs a unique number. A simple sequential system works fine (INV-001, INV-002...), or a date-based one (INV-2026-08-001). What matters is that you never reuse a number — it's how you and your customer both keep track of which invoice is which, especially once you have more than a handful.

4. List what you're billing for

Each line item should have:

• A clear description (not just "services" — say what the service or product actually was)
• Quantity (or hours, for time-based work)
• Unit price

The line total and the invoice total should follow automatically from these.

5. Decide your due date and payment terms

Common options are "due on receipt" (payment expected immediately), or a set number of days like 7, 14, or 30 (often written as "Net 7," "Net 14," etc.). Whatever you choose, state it clearly on the invoice — an invoice with no due date gives the customer no reason to pay promptly.

6. Add your payment details

Bank name, account number, and account name. This is the single most common thing people forget, and it's the one detail that directly delays getting paid — the customer has to come back and ask you for it before they can pay at all.

7. Generate the PDF and send it

Once everything above is filled in, you want a clean PDF — not a screenshot of a spreadsheet — that you can email or share directly with the customer. This is the part a tool genuinely speeds up: type the details in once, get a properly laid-out PDF back immediately.

After you've sent it

The job isn't done once the invoice is sent — you still need to know whether it's been paid, partially paid, or is now overdue. That's the part a plain template can't help with, since a document doesn't track its own status. If you're sending more than the occasional invoice, it's worth having somewhere that shows you, at a glance, who still owes you money.
