How to collect from a client who is not paying you
By Equipo Prestafolio
The four-stage collection ladder, 20 ready-to-copy WhatsApp messages, and the mistakes that turn a late payment into a loss.
A client who is not paying is not (yet) a client who will not pay: most late payments get resolved with the right message at the right time. The most expensive mistake is not lending to someone you shouldn't have, it is collecting badly from someone who was going to pay: an aggressive message on day 2 can turn a simple oversight into a broken relationship, and three weeks of silence can turn a collectible late payment into a loss.
First, understand why they are not paying
Not all late payments are the same, and treating them the same is the first mistake:
Type | Signal | How to collect it |
|---|---|---|
They forgot | Answers fast, apologises, pays within hours | A reminder is enough |
No cash this week | Answers, explains, asks for a few days | Short payment plan, no scolding |
Avoiding the subject | Leaves you on read, excuses keep changing | Firmness and presence, without harassing |
Not planning to pay | Does not answer, changes number, moves away | Escalate fast: guarantor, promissory note, or the legal route |
The first two are 80% of your late payments and get solved in this guide. The last two need more than a message: if you have a signed promissory note, it is your safety net (see Promissory notes and loan contracts); if you do not have one, take this as the lesson for the next loan.
The collection ladder: four stages, not one
Collecting well means climbing one step at a time, not jumping from "hello" to a threat:
Stage | When | Tone | Goal |
|---|---|---|---|
1. Reminder | Due date and +1, +2 | Friendly, assumes good faith | Get them to pay today without feeling accused |
2. Firm follow-up | Day +3 to +7 | Direct, no scolding | A concrete payment date |
3. Negotiation | Week 2 | Firm but flexible | A payment plan they can actually keep |
4. Final notice | Week 3+ | Serious, no empty threats | Leave a record before escalating |
Climbing the ladder too fast burns the relationship with someone who was going to pay. Staying stuck on stage 1 for a month teaches the client that being late has no consequence.
20 WhatsApp messages ready to copy
Copy them and swap in the name and amount. Each one corresponds to a stage of the ladder above.
Stage 1: reminder (5 messages)
# | Message |
|---|---|
1 | Hi [name], just a reminder that your instalment of [amount] is due today. Do you have it ready? |
2 | Hi [name]. Just a heads up that your payment of [amount] was due yesterday. Let me know if anything comes up. |
3 | Hi [name], everything okay? Just checking whether you already made the payment of [amount] or have it scheduled for today. |
4 | [name], I have not received this week's payment of [amount] yet. Let me know if there is any issue. |
5 | Hi [name], sharing the payment details again for [amount] in case you misplaced them: [payment detail]. |
Stage 2: firm follow-up (5 messages)
# | Message |
|---|---|
6 | [name], your instalment of [amount] is now [n] days late. I need you to confirm when you can pay. |
7 | Hi [name]. I have not heard back from my earlier messages. Can we talk today about your outstanding payment? |
8 | [name], I understand things get complicated sometimes, but I need a concrete date for your [amount] payment. When can you? |
9 | Hi [name]. Your instalment of [amount] has been outstanding since [date]. Let me know if you would rather talk by phone. |
10 | [name], if there is some difficulty paying the full instalment, let me know and we will work something out. But I need you to answer me. |
Stage 3: negotiation (5 messages)
# | Message |
|---|---|
11 | [name], here is my proposal: [partial amount] this week and the rest on [date]. Does that work for you? |
12 | Hi [name]. We can split the [amount] instalment into two parts if that helps you catch up. Let me know what you think. |
13 | [name], so the arrears do not keep piling up, how about you pay [partial amount] today and we agree on a date for the rest? |
14 | Hi [name]. I would rather set up a plan you can actually keep than have you keep falling behind. How much can you pay this week? |
15 | [name], we agreed you would pay [amount] on [date] and it did not come through. Do we keep that plan or do you need to adjust it? |
Stage 4: final notice (5 messages)
# | Message |
|---|---|
16 | [name], your instalment of [amount] is now [n] days overdue with no response from you. I need you to get in touch today. |
17 | Hi [name]. This is my third attempt to reach you about the outstanding payment of [amount]. Please answer me before [date]. |
18 | [name], if I do not hear from you by [date], I will have to take the next step on your case, as agreed in what we signed. |
19 | Hi [name]. I value the relationship we have, but you have gone [n] weeks without paying or answering. I need a solution this week. |
20 | [name], leaving you this message as a final reminder before moving forward with the steps that apply for the arrears. I would rather sort this out by talking to you. |
What not to do, even when you feel like it
Mistake | Why it costs you |
|---|---|
Threatening something you will not follow through on | The client notices, stops fearing you and stops answering you |
Messaging their family, their boss, or posting about it online | In most countries that is harassment: you are the one exposed, not just them |
Showing up at their home unannounced, at night | It escalates the conflict and puts you at physical and legal risk |
Raising the rate or the arrears charge "as punishment" without it being agreed | If it was not in the contract, it is your word against theirs |
Letting weeks pass without a single message | Silence pressures nobody: it only makes it harder to pick the contact back up |
The line between collecting firmly and harassing is real, and crossing it can land you, not just the client, in legal trouble. Everything you ask for has to be backed by what you both signed: that is why the promissory note matters more at collection time than at lending time.
When to offer a payment plan and when to escalate
Offer a payment plan when the client answers, explains and proposes something concrete: that is the sign they want to pay. Escalate (guarantor, promissory note, or whatever route you have defined) when the client stops answering, changes their excuse every time, or promises and fails to deliver more than twice in a row. The difference is not how much they owe, it is whether they are still communicating with you.
Frequently asked questions
How many days should I wait before escalating to the next stage? There is no universal number, but the ladder above (reminder for the first 2-3 days, firmness through the week, negotiation in week 2, final notice in week 3) works for most short-term informal loans. If your collection frequency is daily, compress the timing: a 3-day delay on a daily loan already weighs as much as 2-3 weeks on a monthly one.
Should I still charge arrears if the client promises to pay tomorrow? If arrears are agreed in the contract, yes: not charging it "just this once" teaches every client that being late costs nothing. You can negotiate the amount of the overdue instalment, but arrears are a rule, not a favour (see How to calculate arrears on a loan).
Does it help to warn them they will be flagged for future loans? Yes, and it is one of the most effective messages there is because it is not an empty threat: it is a real consequence. A client who knows their payment history is on record (with you and, if you use a system with a shared history, with other lenders too) has a real incentive not to fall behind.
Summary
- Most late payments are from someone who is going to pay: do not treat them as if they were not.
- Climb the collection ladder one step at a time: reminder, firmness, negotiation, final notice.
- Use the 20 messages above as a base, not a fixed script: match the tone to the real relationship.
- Threatening, harassing or showing up unannounced exposes you legally more than the client.
- The signed promissory note is what backs up every message you send: without it, collecting is just asking.
Prestafolio calculates arrears automatically based on the rate and the days late you configure, and keeps every client's history so you know right away who pays well and who does not: see Arrears, Setting the arrears rate and Trust and credit history.
