For the Business The Customer
[Name and role] [Name]
[Date] [Date]Example with figures
A digital agency in Lagos is owed ₦1,200,000 for three months of work. The client asks for four months to pay.
| Installment | Due date | Amount (₦) | Balance after (₦) |
|---|---|---|---|
| 1 | 5 Nov 2026 | 300,000 | 900,000 |
| 2 | 5 Dec 2026 | 300,000 | 600,000 |
| 3 | 5 Jan 2027 | 300,000 | 300,000 |
| 4 | 5 Feb 2027 | 300,000 | 0 |
Both sides sign the letter. The agency sends a reminder before each 5th and a receipt after each payment.
What goes in each part
- Balance. List the invoices it covers. The customer accepts a figure they can trace.
- Payment plan. One line per installment with the exact date. Avoid lines like monthly from November.
- How to pay. Give the account details or say a payment link arrives before each date.
- Interest and charges. Say plainly if the plan adds interest or not. Silence here causes disputes.
- Missed payments. Set a grace period and a written notice before the full balance becomes due.
- Completion. Promise a written confirmation when the balance reaches zero.
- Signatures. Both parties sign and keep a copy. A scanned copy by WhatsApp or email works for most cases.
When a payment agreement makes sense
- The customer wants to pay but cannot clear the balance at once.
- The balance is a few months old and the relationship is worth keeping.
- You want a clear record before thinking about a final demand letter.
- A customer has made partial payments with no fixed schedule.
Common mistakes
- Agreeing on the phone and never writing it down. The schedule changes in each call.
- Installments that do not add up to the total. Check the sum before signing.
- No grace period. A plan that breaks for one day late ends faster than it should.
- Forgetting to remind before each date. Most missed installments are forgotten, not refused.
- Not confirming the last payment. Close the plan in writing.
How to propose a payment plan
Most customers accept a plan when it comes before the account turns hostile. Offer it in a message first, then confirm it with the letter.
- Ask what amount the customer can pay each month. Their number is the one they will keep.
- Propose dates that follow their income, such as the day after payday.
- Keep the plan short. Three to six installments are easier to follow than twelve.
- Send the letter the same day, with the dates and amounts you agreed.
- Remind each installment a few days before its date.
A plan agreed by message and confirmed in writing avoids most later disputes about what was promised.
