Chasing payments is the job nobody wants. The owner feels awkward, the accountant is busy, and so the reminder goes out late, sounds annoyed, or doesn’t go out at all. Meanwhile ₹40,000 of fees, invoices or instalments sit unpaid past the due date.
Most late payers aren’t refusing to pay. They forgot, the invoice got buried, or they’re waiting for their own money to come in. A calm, consistent reminder sequence fixes most of that without damaging the relationship.
This guide is for coaching centres, schools, agencies, wholesalers, clinics, landlords and service businesses. If you are a bank, NBFC or other regulated lender, RBI’s rules on recovery go much further than this article and take priority.
The sequence that works
The idea is simple: start friendly and early, become clearer as time passes, and move to a person well before anything turns unpleasant.
Three days before the due date: a heads-up. A short WhatsApp message with the amount, the date and a payment link. This is a service to the customer, and it prevents most late payments.
Hi Ritu, a quick reminder that the October fee of ₹6,500 for Aarav is due on 5 November. You can pay here: [link]. Thank you!
On the due date: the reminder. Same details, same tone, one line saying the payment is due today.
Three to five days late: the nudge. Mention that the payment is overdue, offer help (“let us know if you need the invoice again or want to discuss a different date”), and include the link again.
Ten days late: a call. A short call, from a person or a carefully set up AI assistant, to ask whether there’s a problem and agree a date. Record the promised date.
After the promised date passes: a person takes over. Owner or accounts lead, not automation. This is where judgement, relationships and sometimes a payment plan matter.
Keep every message factual: amount, invoice or account number, due date, how to pay, who to contact. Leave out anything that sounds like a threat.
The rules that apply
WhatsApp templates. If you use the WhatsApp Business Platform, reminders sent outside an open 24-hour customer service window go out as approved templates. Payment and fee reminders are usually utility templates, which cost far less than marketing templates. Keep them free of offers and promotions, or Meta may classify them as marketing. Our explainer on WhatsApp API charges from October 2026 has the current India rates.
Automated calls. TRAI’s 2026 amendment requires calls placed by software, including AI voice agents and pre-recorded reminders, to be declared to the operator and made from declared numbers. Undeclared automated calls are treated as spam. Our guide to the new calling rules explains what to set up.
Calling hours. For regulated lenders, RBI has barred recovery agents from calling borrowers before 8 am or after 7 pm, as reported when the instruction was issued in 2022. Even if those rules don’t bind your business, it’s a sensible standard. Nobody pays faster because you called at 9:30 at night.
Personal data. Reminders should go only to the person responsible for the payment. Never discuss someone’s dues with their family, employer or neighbours, and never post names of defaulters in groups. Apart from being unkind, it creates privacy and defamation problems.
Lines you should never cross
- No threats of legal action you don’t intend to take, police, or “visits”.
- No shaming, insults, or contacting people other than the customer.
- No repeated calls in a day. One attempt, and a message if unanswered.
- No pretending to be a lawyer, court or government office.
- No adding late fees that weren’t in the original terms.
If a customer disputes the amount, stop the automated sequence immediately and have a person respond.
Make paying easy
The best reminder includes a way to pay in one tap. A UPI payment link or a payment page with the invoice number already filled in removes the most common excuse. Accept part payments where your terms allow it, and confirm every payment with a receipt so customers don’t get reminders for money they’ve already paid. Few things annoy a customer more.
Where automation helps, and where it doesn’t
Automation is good at the first three steps: on time, every time, with the right amount and link. It’s also good at recording promises to pay and updating your accounts sheet. It should not negotiate settlements or handle disputes, hardship or angry customers on its own.
That is how we build an AI collections employee: polite reminders by WhatsApp and call on your schedule, promises to pay recorded, and anything sensitive escalated to your team, with the tone and timing approved by you. For the WhatsApp side alone, our WhatsApp Business API setup covers templates and sending.
Consistency gets you paid. Courtesy gets you paid again next month.
