Core payment terms
A clear invoice should not leave the client guessing. If payment is due immediately, say so. If it is due in seven, fourteen or thirty days, state the exact date as well as the term.
For project work, milestone terms can prevent disputes: deposit before work starts, second payment after draft, final payment before delivery or launch.

Currency and exchange-rate terms
If the client will pay in naira for a quote originally discussed in USD, GBP or EUR, state the conversion rule. Use a clear rate source or an agreed fixed conversion.
This is especially important for long projects where rates can change before final payment.
Dispute prevention
Add enough service description for the client to know what is included. If revisions, delivery files, taxes, expenses or support are separate, write that clearly.
Keep the invoice, payment confirmation and project approval messages together.

Good invoice terms reduce the awkward back-and-forth after delivery
Invoice payment terms should make the agreement easy to act on. State the invoice number, issue date, due date, currency, amount, payment account, tax treatment where applicable, what the charge covers and the person or team that should confirm payment. ‘Pay promptly’ is not a useful due date. Use a clear term such as payment due on receipt, seven days, fourteen days or thirty days only when it reflects the agreement you made with the client.
For Nigerian businesses working with local or international clients, write the currency in words and figures and say whether bank, platform or transfer charges are paid by the client or deducted from the amount. If the price can change because of exchange rates, define the reference rate or the date used. A foreign-currency invoice does not remove the need to comply with the client's procurement rules, tax documentation or your own record-keeping obligations.
Agree the terms before work starts and put them in the quotation or contract as well as the invoice. For a deposit, say whether it is refundable, when the balance is due and whether work pauses after an overdue date. Keep a delivery proof and send one polite reminder before escalation. Avoid threats, public shaming or adding an interest charge that was never agreed. If the client disputes the invoice, ask which line or milestone is disputed and separate that issue from the undisputed amount.
Quick decision helper
What payment term does this invoice need?
Before you finish
A good reminder includes the invoice number, amount outstanding, original due date, payment link or account details and a simple question such as when payment is expected. Send it privately to the client contact and keep a record. If the due date was never agreed, ask for a date first instead of presenting a new penalty as if it already formed part of the contract.
Make the next step easier
For recurring clients, agree whether one monthly invoice, milestone invoices or a deposit-plus-balance arrangement fits the work. Include the person who approves the invoice, the purchase order or project reference and the email address for billing questions. When a client pays only part of the amount, update the balance and send a receipt so both sides have the same record. A payment reminder should be firm and factual; it should not expose the client's debt to other people or threaten action that you are not prepared to take.
