Billing software that reminds your customers on WhatsApp before the due date

Reviewed in October 2026

Makatea is billing software for the part after the invoice. It sends each customer a WhatsApp and email reminder before the due date, follows up when the date passes and records every payment. Upload your customer list from Excel and the first reminders go out the same day. Start free for 14 days with no card.

Reminders on WhatsApp and email

Each customer gets a message with their name, amount and due date. You pick the day, the time and the tone.

A payment link in every message

Connect your payment processor and every reminder carries a link. The money goes straight to your account.

Partial payments

Each payment lowers the balance. The next reminder shows what is left, not the original amount.

Promises to pay

When a customer replies with a date, Makatea pauses and reminds them on that date.

One inbox for every reply

Customer replies from WhatsApp and email land in one place. Your team answers from there.

The Monday summary

Every Monday Makatea emails who paid, who promised and who to follow up first.

How it works

  1. Upload your customer list. Excel or CSV in the format you already use.
  2. Set the reminders. Choose the days before and after the due date and the channel.
  3. Collect and record. Payments by link are recorded on their own. Others are marked in one tap.

The messages your customers get

WhenWhatsApp message
3 days beforeHi Priya, your October fee of ₹4,500 is due on the 25th. Pay here when it suits you. [link]
Due dateHi Priya, today is the due date for ₹4,500. You can pay by UPI or with this link. [link]
3 days afterHi Priya, the ₹4,500 for October has not arrived yet. If you already paid, reply with the reference.
7 days afterPriya, your ₹4,500 is still open. Can you tell me the date you will pay?

You write each message once. Makatea sends it on every date for every customer.

Billing software and collections software

Billing software creates the invoice. Collections software makes sure it gets paid. Most small businesses have the first and run the second by hand.

Makatea covers the second part. It works with the invoices from your current system, your accountant or a spreadsheet.

Payments your customers already use

Customers keep paying the way they already do. UPI, bank transfer, mobile money or card all work with the link of the processor you connect. Makatea never holds your money.

What to look for in billing software

Most billing tools stop when the invoice is sent. These are the points that decide whether the invoice gets paid on time.

  • Reminders on the channel your customers read. In India, Nigeria or the Philippines that is WhatsApp before email.
  • A payment link inside the reminder. Every extra step between the message and the payment costs days.
  • Partial payments that lower the balance. A customer who paid half should never get the full amount again.
  • Promises to pay that pause the sequence. A customer who gave a date should not get the next reminder.
  • Your own number and your own name. Customers answer a business they know, not an unknown sender.
  • A weekly list of who to call. The owner should see the five accounts that matter, not three hundred rows.

Makatea covers all six. Your billing or accounting system keeps doing the invoice and the tax side.

A billing month with figures

A coaching centre bills 180 students a monthly fee of ₹4,500. The fee is due on the 25th of each month.

DayWhat Makatea doesWhat the owner does
22ndSends 180 reminders on WhatsApp with the payment linkNothing
25thSends the due date message to those who have not paidNothing
28thFollows up the rest and records each payment that comes inAnswers the few replies in one inbox
MondayEmails the list of who paid, who promised and who is silentCalls the short list

Before Makatea the owner copied 180 messages by hand each month. Now the owner reads one list on Monday.

Moving from manual reminders to Makatea

Most businesses start with reminders typed by hand from a phone. The move takes one afternoon.

  1. Export the list of open invoices from your billing system or spreadsheet.
  2. Upload it to Makatea and check that names, amounts and due dates read correctly.
  3. Copy the messages you already send into the sequence, or start from the examples.
  4. Connect the WhatsApp line your customers already know.
  5. Turn the sequence on and stop sending reminders by hand that same day.

Customers see no change in the sender. They just get the reminder on time, every month, with a link to pay.

What changes for your customers

Customers get the reminder from the number they already have saved. The message shows their name, the amount and the date.

They pay with one tap on the link, or reply if they need more time. Nobody has to call them to ask.

Customers who always pay on time get one short reminder and nothing else. Only late accounts get the follow-up.
