WhatsApp Collection Message: 12 Polite Templates That Work

Charging via WhatsApp works because the message is read in minutes — but it requires the right tone: firm without embarrassing, clear without threatening. These 12 billing message templates cover everything from preventive reminders to renegotiation agreements, what the law allows and how to automate so you never charge again.

The 3 golden rules of charging on WhatsApp

1. Cover in private, never expose. Billing in groups or with third parties is prohibited by the Consumer Protection Code (art. 42: the consumer cannot be exposed to ridicule or embarrassment).
2. Start by assuming good faith. Most delays are forgetfulness. First message = friendly reminder, not ultimatum.
3. Always offer the payment method. Billing message without link/key Pix is halfway there — make it easy to resolve in the conversation itself.

Before expiration (preventive)

1. D-3 Reminder: "Hi [name]! Just stopping by to remind you that your invoice for R$[amount] is due on [date]. Follow the link/Pix to make it easier: [link]. If you have any questions, just call!"
2. Reminder on the day: "Good morning, [name]! Today is the due date for your invoice of R$[amount]. Follow the Pix: [key]. If you have already paid, please disregard and thank you!"

Preventive is the charge that doesn't look like a charge — and eliminates most delays before they happen. Scheduled once, sends messages on its own: see how to schedule messages.

Recent delay (1 to 7 days)

3. D+1, take: "Hi [name], how are you? I noticed that the invoice for R$[value] was due yesterday. It probably went unnoticed — follow the link to regularize it: [link] 🙂"
4. D+3, direct: "Hello [name]! Your invoice for R$[value] has been outstanding since [date]. Can you settle it today? Follow Pix: [key]. If there is anything unforeseen, let me know and we can resolve it together."
5. D+7, with question: "Hi [name]. The invoice for [date] is still open and I want to avoid any charges for you. Did something happen? Can I help you with a payment condition?"

Extended delay (15 to 30+ days)

6. D+15, formal: "[Name], the invoice for R$[value], due on [date], remains open. To avoid suspension of service, I need it regularized by [deadline]. Link: [link]. I am available to talk about options."
7. D+30, proposed agreement: "[Name], I want to resolve this in the best way for you. I can split the outstanding amount in [N]x or give [X]% discount for payment in cash by [date]. Which option works best?"
8. Pre-closing: "[Name], this is my last attempt to contact you before we forward the case to the measures provided for in the contract. I much prefer to resolve it with you here. Will you answer me by [date]?"

Specific situations

9. Customer who promised and didn’t pay: "Hi [name]! We agreed the payment for [arranged date] and I didn't identify the amount. Was there anything unforeseen? Follow the link again to make things easier: [link]."
10. Payment confirmation: "Received, [name]! Payment confirmed and everything is fine here. Thank you for your partnership! 🙌"
11. Deal closed: "Perfect, [name]! It's agreed: [N]x of R$[amount], every day [day]. I'll send you the reminder before each installment to make it easier. Thank you for your trust!"
12. Post Broken Deal Reactivation: "[Name], the [date] portion of our agreement has not been identified. To maintain the conditions we agreed on, I need payment by [deadline]. Can you do it?"

What the law allows (and what brings you down)

• You can: charge via WhatsApp, remember due date, propose agreement, inform real contractual consequences.
• You cannot: expose the debtor to third parties, threaten, use a harassing tone, charge outside of reasonable hours or insist after a formal request for contact through another channel.
• LGPD: customer data used in billing follows the same rules as any processing — legitimate purpose and storage security^[1].

Automate the billing rule

Efficient collection is a process, not improvisation — and polite persistence pays off: the rule D-3 → D+1 → D+7 → D+15 follows the same logic as sales follow-up, in which most results come out after the fifth contact^[2]. In Zapext, mount it like this:

1. Save the 12 models as quick answers with shortcuts (/d3, /due, /agreement).
2. Apply the "in-charge" label and follow the Kanban — column by delay stage.
3. Schedule preventive reminders when the sale is closed.
