How freelancers and consultants in Nigeria should invoice
When you sell your time and skill, the invoice is the product's receipt. It needs to show what was done, how it was priced, and when you expect payment, especially with companies that pay through an accounts team.
What to put on the invoice
- The project and the period it covers.
- How you price: per hour, per day, per deliverable or a monthly retainer.
- A clear description of each deliverable, not just "services".
- Expenses as separate lines, with receipts if they ask.
- The client's company name and any purchase order number, because accounts teams often need it to pay.
- Payment terms: due in 7, 14 or 30 days, and your late fee if you have one.

Deposit and payment terms
For project work, split payment into milestones: for example 40% to start, 30% at the first draft and 30% on delivery. For retainers, invoice on the same date each month and say what the retainer covers. Companies often pay on 14 to 30 day terms, so state it and send the invoice the same day the work is accepted. Late payment is easier to chase when the terms are on the invoice. See our payment reminder messages.
Problems a clear invoice prevents
- Scope creep. The invoice lists what was agreed, so extra work is a new line.
- Slow company payments. The PO number, terms and a clear contact help their accounts team process it.
- "We did not agree on that price." A quotation first, then an invoice that matches it.
Questions people ask
Should I charge hourly or per project?
Per project or per deliverable is easier for clients to approve. Hourly suits open-ended or unpredictable work.
How do I invoice a retainer?
Invoice on the same date each month, describe what the retainer covers, and keep one running invoice number sequence.
Do I need a client's PO number?
Many companies require it before they can pay. Ask for it when you take the job.
