Sole Trader Invoice Nigeria: Guide and Free Template

If you work for yourself as a designer, consultant, tailor, photographer, contractor or other independent business owner, your invoice should make you look reliable. You do not need a complicated accounting system to get the basics right.

A sole trader invoice is simply a request for payment that identifies you, the customer, the work and the amount due.

What to put on a sole trader invoice

Use your trading name if you have one. If you trade under your own name, use that consistently. Include:

• your name or registered business name and contact details
• the customer’s name and contact details
• an invoice number, date and due date
• a short description of the work or goods supplied
• quantity, rate and total
• payment instructions
• your Tax ID or registration information where relevant

Avoid sending a message that only says, “Please pay ₦50,000.” It gives a customer’s accounts team very little to approve or retain.

Example: freelance designer invoice

If the customer paid a 50% deposit, add a separate line showing the deposit date and amount. Do not alter the quoted price without explaining the change. You can find more examples in our sample invoice guide.

Use clear payment terms

“Payment due on receipt” is suitable where the customer has agreed to pay immediately. For project work, a specific date is usually better. You may state “50% before work starts and 50% on delivery” or “Payment due within seven days of invoice date”.

If the work is linked to an LPO, add the buyer’s reference to the invoice. It helps their accounts team match your bill. Our guide to how LPO payment works explains why this matters.

VAT and withholding tax

Do not add a VAT line just because you have seen one on another person’s invoice. VAT treatment depends on the supply and your tax position. If a client deducts withholding tax, retain the documentation and make sure the invoice amount, payment received and deduction are all clear. Read our withholding tax guide before agreeing figures with a client.

Make invoices easy to check

Give each invoice its own number. A simple format such as PS-2026-001 is enough if it is unique and sequential. Use the same business details on every invoice and make sure your bank account name is not confusingly different from the business named at the top.

You can create a free invoice online, keep a copy for your records and share the PDF with your customer. When payment arrives, issue a receipt and keep the payment reference with the invoice.

Common mistakes

The most common problems are missing due dates, vague descriptions, reused invoice numbers and totals that do not match the quotation. A clear document is easier to pay and easier to defend if there is a later question about the work.
