Does your business handle recurring purchases? Does it offer subscriptions? Or do you simply need to remind your customers about their bill payment?
This is a common problem for many businesses: the end of the month arrives, you send your billing statement, and the customer simply ignores it or forgets to pay. The debt snowballs into a headache for both the customer and your business.
The truth is that, according to research, Most defaulting customers want to pay, but they don't do so because they don't know how to pay or don't pay attention to the due date. – a natural forgetfulness, in the highly accelerated time we are living in.
The solution? Payment reminders!
Those who believe this feature is a nuisance to users are mistaken. On the contrary, while paying customers may ignore the message, forgetful and indebted customers welcome it—an effective service provided by your business.
On the other hand, the advantages of such a resource for your company are noticeable: Payment reminders drastically reduce defaults and the need to take other more radical measures to receive (such as inclusion in a list of debtors and legal actions).
However, you can't keep sending reminders manually! Even with someone managing the collections department, it's practically unfeasible (in terms of growth and scalability) to do it manually. Furthermore, there's no reason to complicate something that Artificial Intelligence can do it masterfully.

Payment Reminders on WhatsApp
You can use whatever communication channels you prefer and make sense for your business; chances are, WhatsApp is one of them. That's because 99% of Brazilians have the application installed on their smartphones; and 97% open the app every day (data from the Panorama Mobile Time/Opinion Box Survey – Feb/2025).
It is also possible just forward an automated reminder message to the user via WhatsApp – this short text alone is already a great help to remind the user of the financial commitment and proceed with the payment. Remember that To automate the sending of messages via WhatsApp, you must have the API version of the application., hired via Official Partner of Meta, like the Matrix Go.
But for the sake of example, let's go further! How about not just sending a payment reminder, but provide the selection of the plan, payment method and more, offer payment – all within WhatsApp?!
With the WhatsApp Flows, you can provide automated services within the application – the billing model being one of them. It allows companies achieve better performance by creating more integrated and personalized experiences on WhatsApp.
Along with him, the WhatsApp Payments allows users make payments without leaving the app; and the best part, you can track the status of each payment in real time on your digital communication platform, in our case, in Chatbots & AI from the Matrix Go.

WhatsApp Flows and Payment Reminders
Initially, it is important to say that the WhatsApp Flows is also an exclusive feature of WhatsApp Business., accessible on your WhatsApp Manager. It is necessary to follow the commercial messaging policies from WhatsApp and enable business-initiated messaging in the Business account.
It also has three forms of editing:
– Message Template Editor: The message template is the simplest way to build flows in WhatsApp Flows, as it doesn't require code or dynamic data. Using a drag-and-drop tool, you can create simple flows.

– Flow Builder: A more advanced tool for editing, previewing, and managing flows. More technical, it requires some programming knowledge, as it allows direct editing of Flows' JSON.

– Flows API: Even more flexible and technical, you can use the Flows API to manage flows programmatically, creating custom tools and integrating Flows into your system.

It is important to say that, if you do not master the last two editing models and wish to create a more complex journey, it is always possible to count on the support of Meta's Official Partners – here at Matrix Go, our team is always available to help and we count on dedicated consulting packages for your business.
