Updated on October 25, 2026<\/em><\/p>\n\n\n\n

A WhatsApp billing reminder sequence (in Brazil, a r\u00e9gua de cobran\u00e7a<\/em>) is a series of reminders sent before, on and after an invoice’s due date, using utility templates approved by Meta. To avoid getting blocked, every message must be about the customer’s own account only, with no promotional tone and no threats, short sending intervals and a clear stop point. WhatsApp’s policy lists “debt collection” among prohibited services, so a sequence is for a business reminding its own customers about their own invoices, not for running collections on behalf of third parties.<\/p>\n\n\n\n

This guide shows where Meta draws the line, the steps of a sequence, how to write the templates, how to add Pix and boleto payment buttons, and what Brazil’s Consumer Protection Code says about how to collect. (Quick context: Pix<\/strong> is Brazil’s instant payment system; a boleto<\/strong> is a bank payment slip with a due date and a numeric “digitable line”.)<\/p>\n\n\n\n

What Meta allows and what it prohibits<\/h2>\n\n\n\n

Two Meta rules define the space for billing reminders.<\/p>\n\n\n\n

The first is in the template categorization guidelines<\/a>. Among utility examples, under “account alerts or updates”, Meta lists a payment reminder: “Reminder: Your monthly payment for {{service}} will be billed on {{date}} to the {{card}} you have saved on file.” Reminding customers about their own bill is an expected use.<\/p>\n\n\n\n

The second is section 4 of the WhatsApp Business Messaging Policy<\/a> (updated September 23, 2026), which prohibits using WhatsApp for Business to buy, sell, promote or facilitate certain goods and services. The list includes “payday loans, paycheck advances, peer-to-peer lending, debt collection, and bail bonds”, and the ban applies “irrespective of the global or local licenses, registrations, or other approvals your business may hold”.<\/p>\n\n\n\n

In practice:<\/p>\n\n\n\n

Scenario<\/th>Reading<\/th><\/tr><\/thead>
School, gym, SaaS or internet provider reminding its own customer of a monthly fee<\/td>Account reminder, a listed utility use<\/td><\/tr>
Store warning about the boleto due date for an order<\/td>Notice about the customer’s transaction<\/td><\/tr>
Collection agency hired to recover third-party debts<\/td>Fits “debt collection”, a prohibited service<\/td><\/tr>
Company that buys debt portfolios and contacts debtors<\/td>Fits “debt collection”, a prohibited service<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Meta decides cases at its own discretion. If collections are your business, read the whole policy before investing in the integration.<\/p>\n\n\n\n

Steps of a reminder sequence<\/h2>\n\n\n\n

There is no official sequence. The table below is a model to adapt to your terms and payment history:<\/p>\n\n\n\n

Step<\/th>Timing<\/th>Goal<\/th>Button<\/th><\/tr><\/thead>
Invoice available<\/td>At issuance<\/td>Send amount, due date and payment method<\/td>Pix, boleto or link<\/td><\/tr>
Reminder<\/td>2 to 3 days before<\/td>Remind those who have not paid<\/td>Pix or boleto<\/td><\/tr>
Due date<\/td>On the day, in the morning<\/td>Last notice within the deadline<\/td>Pix or boleto<\/td><\/tr>
Early overdue<\/td>1 to 3 days after<\/td>Report the delay and the new way to pay<\/td>New Pix or updated boleto<\/td><\/tr>
Persistent overdue<\/td>About a week after<\/td>Offer contact with a person<\/td>“Talk to an agent” quick reply<\/td><\/tr>
Closing<\/td>Per company policy<\/td>State the next step set out in the contract<\/td>None or support<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Three operating rules prevent most problems:<\/p>\n\n\n\n

    \n
  1. Stop the sequence on payment.<\/strong> Check with the bank or payment service provider (PSP) right before each send. An overdue notice to someone who already paid is the most common complaint.<\/li>\n\n\n
  2. One message per step.<\/strong> Do not resend the same template on the same day, or when the previous message was not read.<\/li>\n\n\n
  3. Long delays go to people.<\/strong> After a few attempts with no reply, the automated sequence stops and the case moves to human support or another channel.<\/li>\n\n<\/ol>\n\n\n\n

    Writing utility templates<\/h2>\n\n\n\n

    Utility requires non-promotional, user-specific text. For billing, that means concrete invoice data and no incentive:<\/p>\n\n\n\n

    Text<\/th>Likely category<\/th>Why<\/th><\/tr><\/thead>
    “Your {{1}} invoice of {{2}} is due on {{3}}. Use the button below to copy the Pix code.”<\/td>Utility<\/td>Account alert with specific data<\/td><\/tr>
    “We have not identified payment for invoice {{1}}, due on {{2}}. If you already paid, please disregard this message.”<\/td>Utility<\/td>Account update, no persuasion<\/td><\/tr>
    “Settle today with 30% off!”<\/td>Marketing<\/td>Offer with a financial incentive<\/td><\/tr>
    “Your subscription expires on {{1}}. Renew today at a discount.”<\/td>Marketing<\/td>Meta cites discounted renewal attempts as marketing<\/td><\/tr>
    “Final notice before legal action!!!”<\/td>Rejection or blocks<\/td>Threatening tone, triggers reports and conflicts with consumer law<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

    Since April 2025, a template submitted as UTILITY<\/code> that Meta considers marketing is approved as MARKETING<\/code>, and approved templates keep being reassessed. Watch the template_category_update<\/code> webhook. Our article on marketing, utility or authentication<\/a> lists the criteria, and rejected templates<\/a> covers the most common rejection reasons.<\/p>\n\n\n\n

    A renegotiation offer with a discount tends to be marketing because it carries an incentive. If your sequence has that step, create a separate marketing template and send it only to people who opted in to offers.<\/p>\n\n\n\n

    Pix and boleto inside the message<\/h2>\n\n\n\n

    In Brazil, Meta lets you add up to three PAYMENT_REQUEST<\/code> buttons to a utility template, with a dynamic Pix code, a boleto digitable line, a payment link or one-click card payment (payment request CTA templates<\/a>). The header can be a document, so you can attach the invoice PDF.<\/p>\n\n\n\n

    Sending an invoice with the PDF in the header and two buttons (boleto and Pix):<\/p>\n\n\n\n

    {\n  \"messaging_product\": \"whatsapp\",\n  \"to\": \"5584999999999\",\n  \"type\": \"template\",\n  \"template\": {\n    \"name\": \"fatura_disponivel\",\n    \"language\": { \"code\": \"pt_BR\" },\n    \"components\": [\n      { \"type\": \"header\", \"parameters\": [\n        { \"type\": \"document\", \"document\": { \"link\": \"https:\/\/example.com\/invoices\/2026-10-4471.pdf\", \"filename\": \"invoice-october.pdf\" } } ] },\n      { \"type\": \"body\", \"parameters\": [\n        { \"type\": \"text\", \"text\": \"outubro\" },\n        { \"type\": \"text\", \"text\": \"R$ 249,00\" },\n        { \"type\": \"text\", \"text\": \"10\/11\/2026\" } ] },\n      { \"type\": \"button\", \"sub_type\": \"payment_request\", \"index\": \"0\", \"parameters\": [\n        { \"type\": \"action\", \"action\": { \"payment_request\": { \"payment_setting\": {\n          \"type\": \"boleto\", \"boleto\": { \"digitable_line\": \"INVOICE_DIGITABLE_LINE\" } } } } } ] },\n      { \"type\": \"button\", \"sub_type\": \"payment_request\", \"index\": \"1\", \"parameters\": [\n        { \"type\": \"action\", \"action\": { \"payment_request\": { \"payment_setting\": {\n          \"type\": \"pix_dynamic_code\", \"pix_dynamic_code\": { \"code\": \"INVOICE_PIX_CODE\" } } } } } ] }\n    ]\n  }\n}<\/code><\/pre>\n\n\n\n
    At creation, each button label must be one of the fixed values in the documentation (Copy Boleto code<\/code>, Copy Pix code<\/code>, Open payment link<\/code>). Meta notes two caveats: WhatsApp does not disable the button when the code expires, and it does not reconcile payments. Generate a fresh Pix code at each overdue step and confirm payment through your PSP.<\/p>\n\n\n\n
    Frequency and number quality<\/h2>\n\n\n\n
    The sequence runs every month, for many people at once, so it weighs on your number’s quality. Meta calculates quality from blocks, reports and other recent signals and, when quality drops, pauses templates and can limit the account (policy enforcement<\/a>). Our article on number quality<\/a> explains the ratings and their effects.<\/p>\n\n\n\n
