How to Ask a Client for Payment Without Losing Them (Scripts Inside)
Most late payments aren't refusals. They're a busy client, an unclear invoice or a hard way to pay. Here is the 3-7-14 follow-up method and the exact WhatsApp and email messages to send at each step.

Tolu runs an events decor business in Surulere. Last month she dressed a 40th birthday in Lekki for ₦850,000. The client paid 60% upfront and promised the balance of ₦340,000 "next week."
Six weeks later, Tolu has typed "Good afternoon ma, please remember the balance" four times. She deleted it every time. She didn't want to sound rude, and the client had promised to refer her sister's wedding.
(Tolu is a composite example, built from stories Nigerian business owners tell us every week.)
If this sounds like you, you aren't bad at business. You're missing a system. Asking for money feels personal only when you make it up as you go. When the same polite messages go out on the same days to every client, it becomes routine, for you and for them.

Why clients pay late (it's rarely personal)
When money is late, we assume the worst: the client is dodging us. Sometimes that's true. Far more often, the reason is boring:
They forgot. You are one of 40 things on their mind.
The request was unclear. The amount, account number and due date are scattered across a chat from three weeks ago.
Paying is a hassle. They're on their phone, your account details aren't in front of them, and the bank app wants a token.
Someone else approves it. In a company, the person you worked with may not be the person who pays. Finance needs an invoice, maybe a purchase order (PO) number.
Cash is tight. They want to pay, but not this week.
They're unhappy and haven't said so. Something about the job bothered them, so they're quietly holding back.
Only the last two are hard. The first four are solved by a clear invoice, an easy way to pay and reminders that arrive on time. That covers most late payers.
Why this matters more than another sale
At Next Mile we use a simple equation for small businesses:
Revenue kept = Conversations × Close rate × Average job × Paid-on-time rate
Every term multiplies the others. Say you bill ₦2,000,000 a month and 80% arrives on time. You keep ₦1,600,000 to work with. Lift that to 95% and you keep ₦1,900,000: an extra ₦300,000 a month, or ₦3.6 million a year, without one new customer.
Chasing payment isn't admin. It's one of the cheapest ways to grow.
Before you ask: make paying easy
The best reminder is an invoice that leaves no questions. Before the due date, check that every invoice has:
An invoice number and issue date, so the client's finance team can find it
A due date in words ("Due: Friday 14 March"), not "payable on receipt"
Clear line items that match what you quoted
The total in naira, with VAT on its own line if you're registered (see our VAT guide for small businesses)
Your account name, bank and number, written out in full
A payment link, so they can pay by card, transfer or USSD in one tap
A payment link removes the biggest excuse. Paystack, for example, charges 1.5% + ₦100 on local payments, waives the ₦100 under ₦2,500, and caps fees at ₦2,000 per transaction (Paystack pricing). On Tolu's ₦340,000 balance, 1.5% + ₦100 would be ₦5,200, so the cap applies: she pays ₦2,000 to get ₦340,000 today instead of "next week." That is a good trade.
Agree the due date before the job starts. "Balance due on delivery day" written on your quote is far easier to enforce than a promise made at the party. (Our guide on writing a quotation that wins shows where to put it.)
The 3-7-14 follow-up method
Here is the schedule. It starts before the due date, because a friendly heads-up prevents half of all late payments.
When | Channel | Tone |
|---|---|---|
3 days before due | Warm heads-up | |
Due date | WhatsApp + email | Friendly, clear |
3 days late | Light check-in | |
7 days late | Phone call, then WhatsApp | Direct: ask for a date |
14 days late | Formal: statement of account | |
30 days late | Email + letter | Final notice |
Three rules make it work:
Send on schedule, every time. Consistency is what makes it feel normal, not personal.
Every message has one ask and the link or account details in it. Never make them scroll up.
Change channel as it gets later. A WhatsApp nudge is light. A call is serious. An email with a statement is formal.
The scripts
Copy these, then change the names and amounts. Keep the respect Nigerian clients expect ("Good morning sir/ma") and keep it short.
3 days before the due date (WhatsApp)
Good morning Mrs Adeyemi 😊 I hope the family enjoyed Saturday. Just a quick heads-up that the balance of ₦340,000 is due this Friday. Here's the link to pay in one tap: [link]. Thank you!
On the due date (WhatsApp + email)
Good morning ma. Today's the due date for invoice #0142 (₦340,000). You can pay here: [link], or by transfer to Tolu Events, GTBank, 0123456789. Please send me a quick message once it's done so I can mark it paid. Thank you!
For a company, send the email to the person who approves payment and copy your contact:
Subject: Invoice #0142 due today: ₦340,000
Dear Accounts team, Please find attached invoice #0142 for the decor at the Lekki event, PO 7781, due today. Payment details and a payment link are on the invoice. Let me know if you need anything else to process it.
3 days late (WhatsApp)
Hi Mrs Adeyemi, just checking the payment for invoice #0142 came through on your side? I haven't seen it yet. Here's the link again in case it's easier: [link] 🙏
This wording is deliberate. "Came through on your side?" gives them an easy way to save face (maybe the transfer failed) while making clear it hasn't arrived.
7 days late (call first, then WhatsApp)
Call. A voice is harder to ignore and lets you hear whether something is wrong. Ask one question: "When can I expect it?" Then confirm in writing:
Thank you for taking my call, ma. As we agreed, I'll expect the ₦340,000 by Wednesday. I'll send the link that morning.
14 days late (email)
Subject: Overdue: invoice #0142, 14 days past due
Dear Mrs Adeyemi, Our records show ₦340,000 on invoice #0142 is now 14 days overdue. I've attached a statement of your account. Please arrange payment by Friday. If there is a problem with the work or the invoice, please tell me so we can sort it out.
Notice the last line. At 14 days, ask directly if something is wrong. It brings a silent complaint into the open, where you can fix it.
30 days late (final notice)
Dear Mrs Adeyemi, Invoice #0142 (₦340,000) is now 30 days overdue, despite our reminders on [dates]. Please pay by [date, 7 days away]. After that date we'll need to pass this to our lawyer for recovery, which I would much rather avoid
Only say what you will actually do. An empty threat teaches a client your deadlines don't mean anything.
When they say "I'll pay next week"
"Next week" is not a date. Your job is to turn it into one, kindly:
No problem at all, ma. Shall I put you down for Tuesday the 18th? I'll send the link that morning so it's easy
If cash is the real issue, offer a split:
If it helps, you could pay ₦170,000 now and ₦170,000 on the 30th. Would that work?
Half now beats all of it never. Write down whatever you agree, and send it back to them in the chat.
The hard cases
The client who disputes the work. Listen first. Separate the part they're unhappy with from the rest: "I hear you about the flowers. Can we settle the ₦290,000 for everything else today while I sort out the flowers?" Most disputes are about one item, not the whole job.
The ghost. No replies to WhatsApp? Call from another line, email, or, for a company, contact the finance or admin office directly. Silence usually means embarrassment, not refusal.
Bigger companies. Mid-size and large firms often pay in fixed payment runs. Ask on day one: Who approves invoices? Do you need a PO number? Which day do you pay suppliers? Getting your invoice in two days before the payment run can save you a month.
The last resort. If someone simply won't pay, a lawyer's letter of demand often works. Lagos State also runs small claims courts for smaller debts; ask a lawyer about the current limit and process. Keep every invoice, message and call note, because they are your evidence.
Stop late payment before the job starts
The easiest debt to collect is the one you never allow to build up.
Take a deposit. 50% to 70% upfront is normal for events, creative work and custom orders. For a new client, consider asking for more.
Bill in milestones on long jobs: a third at start, a third midway, a third on delivery.
Put payment terms on the quote, and get the client to accept it in writing ("I accept" on WhatsApp counts as a record).
Agree what happens when payment is late, such as pausing work, before it happens.
Track who owes what. If you can't see your total overdue in one number, you can't manage it
Set it up once, then stop typing awkward messages
The 3-7-14 method works on paper. It works far better when nobody has to remember it.
In Next Mile, you send the invoice in naira, with VAT if you need it and a Paystack link, straight to the client's WhatsApp or email. Reminders then go out on your schedule, in your words, and you see everyone who owes you on one screen. When a client pays, the invoice marks itself paid and the reminders stop. Tolu wouldn't have needed to type that message at all.
If you don't use any software, the method still works. Put the schedule in your phone calendar and save the scripts as quick replies in WhatsApp Business.
