Quick answer: Common invoice payment terms in Nigeria include "due on receipt" for one-off or small jobs, and "net 7" or "net 14" for ongoing corporate clients. To get paid faster: state the due date clearly on every invoice, request a deposit upfront for larger jobs, send the invoice immediately after delivery, and follow up with a polite reminder as soon as the due date passes rather than waiting weeks.
Common Invoice Payment Terms Used in Nigeria
| Term | Meaning | Typical Use Case |
|---|---|---|
| Due on receipt | Payment expected immediately upon delivery of the invoice | Small jobs, one-off sales, walk-in customers |
| Net 7 | Payment due within 7 days of the invoice date | Regular clients with an established relationship |
| Net 14 / Net 30 | Payment due within 14 or 30 days | Corporate clients with formal procurement/finance processes |
| 50% deposit, balance on completion | Half paid upfront, remainder on delivery or handover | Construction, custom orders, large one-off projects |
| Staged/milestone payments | Payment released as agreed project stages are completed | Construction and long-duration projects |
Why Clear Payment Terms Matter
Ambiguous or missing payment terms are one of the most common reasons Nigerian small businesses experience cash flow problems. If your invoice doesn't state a due date, a client has no obligation — real or perceived — to prioritise your payment over anyone else's. Setting a clear term upfront, ideally agreed before work even begins, gives you a legitimate basis to follow up firmly once the deadline passes.
Strategies to Get Paid Faster
- Request a deposit for larger jobs. A 30–50% upfront deposit before starting work protects your cash flow and filters out clients who were never serious about paying.
- Invoice immediately, not days later. Send the invoice the same day you deliver goods or complete a milestone, while the value of the work is still fresh in the client's mind.
- State the due date explicitly. "Payment due within 7 days of invoice date" is unambiguous. "Please pay soon" is not.
- Make payment easy. Include your bank account details directly on the invoice, and consider a shareable payment link so the client doesn't need to ask you for details separately.
- Offer a small early-payment incentive for large invoices — for example, a 2% discount for payment within 3 days — which can meaningfully improve how quickly corporate clients release funds.
- Apply a late payment clause. Stating a modest late fee (e.g. 1–2% per week overdue) on the invoice, even if rarely enforced, signals that you take your payment terms seriously.
How to Follow Up on an Unpaid Invoice
Most late payments are not malicious — they are the result of a client's own cash flow timing, an invoice that got buried in an inbox, or an internal approval process taking longer than expected. A structured follow-up approach gets better results than either silence or an aggressive first message:
- 1–2 days after due date: Send a polite reminder — "Just following up on Invoice #INV-2026-014, due on [date]. Kindly confirm when payment will be made." Attach the invoice again in case it was misplaced.
- 1 week overdue: Follow up by phone call in addition to a message. A direct conversation often surfaces the real reason for delay — and gives you a verbal commitment to a new date.
- 2+ weeks overdue: Send a firmer written reminder referencing your payment terms and any late fee clause. Propose a specific new payment date rather than leaving it open-ended.
- Persistent non-payment: For significant amounts, consider a formal demand letter (a lawyer can draft one cheaply for a straightforward debt) before escalating to legal action or a dispute resolution process, especially for registered business-to-business contracts.
Preventing Late Payment Before It Happens
The most effective fix for late payment is prevention rather than collection. Agree payment terms in writing before starting any work — even a simple confirmed quotation or signed contract counts. For new or unfamiliar clients, especially on larger jobs, always request a deposit. For construction and long-duration projects, use staged/milestone invoicing (see our guide on invoicing for construction work) rather than waiting until full completion to bill, which concentrates all your payment risk into a single, large, delayed invoice.
Tracking Payment Status
As your client list grows, tracking who has paid, who is overdue, and by how many days becomes difficult to manage from memory or a notebook. A dedicated invoicing tool that tracks invoice status (draft, sent, paid, overdue) removes this guesswork and makes it immediately obvious which clients need a follow-up today.
The Real Cost of Late Payment on Cash Flow
Late payment doesn't just delay when you receive money — it actively constrains your ability to run your business day-to-day. A contractor waiting on a delayed ₦2 million interim payment may be unable to buy the next batch of materials, pay labourers on time, or take on a new job that requires upfront mobilisation cost. This ripple effect is why experienced Nigerian business owners treat payment terms as seriously as the price itself: a slightly lower price with guaranteed prompt payment is often more valuable than a higher price paid unpredictably late. When negotiating with new clients, it is entirely reasonable to factor payment reliability into how you price and structure a job, not just the raw cost of materials and labour.
Setting Expectations With New vs Repeat Clients
Payment terms don't need to be identical for every client. With a new or unfamiliar client, it is reasonable to request a larger upfront deposit and shorter payment terms (e.g. "due on receipt" rather than "net 14") until a track record of reliable payment is established. Long-standing clients who have consistently paid on time can reasonably be extended more flexible terms, since the relationship itself carries lower risk. Reassess these terms periodically — a client who was reliable a year ago but has recently started paying late is a signal to tighten terms again, not a pattern to simply tolerate indefinitely. Document any change in terms clearly on the next invoice you send, rather than changing them silently, so the client understands why the arrangement has shifted.
Frequently Asked Questions
Is charging a late payment fee legal in Nigeria?
Yes, provided the fee is reasonable and was clearly stated as a term on the original invoice or contract before the work was carried out. Retroactively adding a late fee to an already-issued invoice is not enforceable.
What should I do if a client refuses to pay entirely?
Start with documented, written follow-up (email or messages, not just phone calls, so there is a record). For significant amounts, a lawyer's demand letter is often enough to prompt payment before any court action becomes necessary.
Should I stop work if a client misses a staged payment?
For construction and long-duration projects, yes — many standard contracts explicitly allow work to pause if an agreed milestone payment is not received, and continuing to invest labour and materials without payment significantly increases your financial risk.
How do I know if my payment terms are too generous?
If you regularly find yourself short on cash for materials or labour while waiting on client payments, your terms — or your deposit requirements — are likely too lenient for your current cash flow needs and should be tightened for new jobs.
Can I offer an early-payment discount instead of a late-payment penalty?
Yes, and many Nigerian businesses find a positive incentive easier to enforce and better received than a penalty — a small discount for payment within a few days often achieves the same faster-payment goal with less friction.
