Payment Reminder Templates That Actually Get Paid in India

Indian B2B works on credit. Your customer got goods in March, said “30 days payment terms”, and now it’s June. You’ve sent 2 polite reminders on WhatsApp. Nothing. Your cash flow is drying up and you don’t want to burn the relationship.

The problem isn’t usually that customers refuse to pay — it’s that your reminder ended up at message #247 in their WhatsApp scroll, got buried, and nobody in their accounts team has seen it in 40 days.

This post is a copy-paste template library for the four moments you’ll typically send a reminder: at due date, 7 days overdue, 30 days overdue, and 60+ days overdue. Each has one WhatsApp version and one email version. Tone escalates correctly for Indian business norms — polite gets you through Week 1, firm through Week 4, and legal-language after 60 days.

The four-stage escalation

Before templates, the logic:

Stage	When	Tone	Action expected
Stage 1	On due date	Friendly nudge	Wait 7 days
Stage 2	7 days overdue	Polite, specific	Wait 14 more days
Stage 3	30 days overdue	Firm, referenced	Direct call + escalation warning
Stage 4	60+ days overdue	Formal, written	Legal notice or small-claims action

Skip a stage and you’ll either look aggressive (jumping to Stage 3 on Day 8) or pushover-ish (still sending Stage 1 politeness on Day 45). Calibrate to the day count.

Stage 1 — On the due date (or Day +1)

WhatsApp

Hi [Name], hope you are well.

Just a friendly reminder — invoice [INV/2026-27/00147] dated 15 April for ₹1,23,000 is due today. Payment can go to the details on the invoice or the UPI ID [business-name@hdfc] for quick transfer.

Let me know if anything is pending from our side. Thanks!

Why this works: Short. Specific invoice number. Payment method repeated (they’ll lose the invoice, not the WhatsApp). Ends with an out (“if anything is pending”) in case they genuinely have a question.

Email

Subject: Payment reminder — Invoice INV/2026-27/00147 (₹1,23,000)

Hi [Name],

Just a quick reminder that invoice INV/2026-27/00147 for ₹1,23,000, dated 15 April, is due today (15 May).

For your convenience:

• NEFT/RTGS to our HDFC account (details on the invoice)
• UPI: business-name@hdfc

Please let me know if you need anything from our side — a copy of the invoice, GSTIN verification, or a PO reference.

Regards, [Your name]

Stage 2 — 7 days overdue

WhatsApp

Hi [Name], checking in on invoice [INV/2026-27/00147]

This was due on 15 May. It’s been a week — I wanted to make sure it hadn’t slipped through.

The amount is ₹1,23,000. UPI: business-name@hdfc, or the bank details on the original invoice.

If there’s a delay from your end or something I can help unblock, just let me know. Thanks!

Why this works: The word “slipped” is forgiving — it doesn’t accuse. “Unblock” invites them to share the real reason if there is one (awaiting GRN / PO approval / cheque signing).

Email

Subject: Overdue — Invoice INV/2026-27/00147 (₹1,23,000)

Hi [Name],

I wanted to follow up on invoice INV/2026-27/00147 for ₹1,23,000. The payment due date was 15 May — it’s now 7 days past.

Could you let me know when we can expect payment? If there’s anything blocking the processing on your side (additional documents, PO updates, TDS confirmation), happy to assist.

Attached the invoice PDF again for reference.

Regards, [Your name]

Pro tip: Attach the PDF again. They’ll claim they can’t find the original when they reply.

Stage 3 — 30 days overdue

This is the “friendly firmness” moment. Shift tone. Reference the original due date explicitly. Invoke a specific next action.

WhatsApp

Hi [Name], I need to follow up seriously on this one.

Invoice [INV/2026-27/00147] for ₹1,23,000 was due on 15 May — that’s 30 days ago.

I’ve sent 2 earlier reminders. I understand things get busy, but at this point I need to either:

1. Receive payment this week, or
2. Understand specifically what’s pending and a firm new date.

Could we get this resolved by [date — 5 days out]? A call would also work if easier — I’m on [your number] anytime.

Thanks.

Why this works: Shifts from “when possible” to “this week”. Numbered options force a reply. Offers a call — much harder to ignore than text. Doesn’t threaten yet.

Email

Subject: URGENT — Invoice INV/2026-27/00147 overdue 30 days

Hi [Name] (and CC: [their accounts team if you have it]),

This is a firm follow-up on invoice INV/2026-27/00147 for ₹1,23,000. It was due on 15 May — today is 14 June, making this 30 days overdue.

Previous reminders sent on 15 May and 22 May have gone unanswered. I’d like to request either:

1. Confirmation of payment transfer this week, or
2. A written response outlining the specific reason for the delay and a firm new payment date.

If I don’t hear back by 20 June, I’ll need to pause new orders on your account and discuss further steps with my accounts team.

I’d prefer to resolve this cleanly — please reply or call me at [number].

Regards, [Your name]

Pro tip: CC the accounts team when you get to Stage 3. Their own internal queue will surface the payment.

Stage 4 — 60+ days overdue

At 60 days you’re in formal territory. The message is short, firm, and references next steps (legal, reporting, halt supply) explicitly. Tone should be cold — warm tones here read as weakness.

WhatsApp

[Name], please treat this as a final reminder.

Invoice INV/2026-27/00147 of ₹1,23,000 is now 60 days overdue.

If payment or a specific, written repayment schedule is not received by [date — 5 days], I will:

1. Issue a formal legal notice via my advocate
2. Report the default to [relevant credit bureau or industry body]
3. Add this to the GST scrutiny/complaints mechanism if GSTIN was provided

I strongly prefer to close this without going there. Please call me on [number] today.

Email (this one should be BCC’d to your own inbox + cc’d to their finance head if you have the contact)

Subject: Final notice before legal action — INV/2026-27/00147 — ₹1,23,000

[Name] / [Finance Head CC],

This serves as formal written notice that invoice INV/2026-27/00147 for ₹1,23,000 (dated 15 April 2026) remains unpaid 60+ days past its due date of 15 May 2026.

Despite multiple reminders on 15 May, 22 May, and 14 June 2026, no payment or written response has been received.

Unless full payment (or a specific, written repayment plan) is received by 20 July 2026, I will be compelled to:

1. Issue a formal demand notice via my advocate under Section 138 of the Negotiable Instruments Act (if any cheque was dishonoured) or under the Commercial Courts Act / Section 9 of the Arbitration & Conciliation Act.
2. File a summary suit for recovery under Order XXXVII of the Code of Civil Procedure.
3. Report the non-payment to relevant industry associations and credit reference bureaus.
4. Raise the matter on the GST portal’s complaint mechanism, noting the GSTIN provided at the time of invoice.

Please find the invoice and reminder trail attached.

I continue to be open to a commercial resolution and can be reached at [number] or [email].

[Your name] [Your company] [Date] [Your GSTIN]

Send this one via email (not WhatsApp) — it’s a formal document. Use a read-receipt if your email tool supports it.

The tone rules for Indian B2B

• Never insult. The Indian business world is small. Today’s defaulter is tomorrow’s referral source.
• Never public-shame. No LinkedIn posts, no industry-group complaints unless you’re truly at Stage 4.
• Always give an out. “Let me know what’s blocking this” leaves a face-saving path for the customer to come clean about cash flow or PO issues.
• Escalate clearly. Don’t drift from Stage 2 to Stage 3 with no visible change of tone — the customer stops reading.
• Own your own invoice quality first. If your invoice was ambiguous (wrong GSTIN, missing PO reference, wrong bank account), you’ve lost the moral high ground before you send Reminder #1.

What 21bill automates

• Email reminders on a schedule: the tool sends overdue-invoice email reminders at preset day-counts (today: 3 days before due, 3 days after) without you lifting a finger. Per-org configurable day-counts + WhatsApp reminders are on the 2026 roadmap.
• Customer-level aging dashboard: see at a glance who owes you what at 30 / 60 / 90+ day buckets.
• Payment status on each invoice: marking “paid” or “partially paid” auto-stops future reminders.
• Built-in email template: our default reminder copy is a clean, friendly version of Stage 1 above. Customising the email template body is on the roadmap.

We don’t do legal notices for you (that’s your CA or advocate). But we take the repetitive chasing off your plate so you can focus on the 60+ day ones that actually need a phone call.
