The short version:
- Watsio’s collections assistant reminds customers of the amount due, sends a payment link, offers an installment plan, and hands the chat to a team member if the customer disputes it.
- Customers pay with mada, Apple Pay or STC Pay through Tap, PayTabs or Paymob, and the e-invoice is created from the same chat.
- A utility reminder message costs about SAR 0.04 at Meta’s rate, and Watsio adds no markup.
Collecting money is one of the heaviest jobs for any business owner. Phone calls are awkward, messages from an employee’s own phone go untracked, and small amounts pile up until they become big ones. In most cases the customer is not avoiding you. They forgot, or did not have an easy way to pay at the time. This is where WhatsApp helps: a polite reminder at the right time, a ready payment link inside the message, and an installment option for those who need it. This guide explains how to build a collections process on WhatsApp, how to write reminders that do not upset customers, and which rules to follow.
Why WhatsApp works for collections
- Your customer is already there: most of your conversations with them already happen on WhatsApp, so the reminder arrives in the place where they know you.
- One-tap payment: the link is inside the message, with no account number to copy and no app to open.
- Less awkward: a friendly written message is easier for both sides than a phone call asking for money.
- Everything is on record: the invoice, the reminder and the customer’s reply sit in one chat your team can see, not on someone’s personal phone.
How the collections assistant works in Watsio
The collections cycle on WhatsApp
- The amount dueYou set the customer and amount, or start from an invoice already in their profile.
- The reminderA WhatsApp message reminds them of the amount due, politely.
- The payment linkThe customer pays with mada, Apple Pay or STC Pay inside the chat.
- An installment planIf the customer cannot pay in full, the assistant offers an installment plan.
- A disputeIf the customer says the amount is wrong, the chat goes to a team member with a summary.
The assistant never sends a payment link or invoice without confirming with the customer first, because that is a fixed rule for any action involving money. There is also a ready collections assistant among the assistant templates for 11 business types, so you do not start from scratch.
How to write a reminder that does not upset the customer
The goal is to get paid and keep the customer. So tone matters as much as timing. Here are examples you can build your templates on, with variables such as the customer name and amount:
- Before the due date: “Hi {name}, a quick reminder that your invoice of SAR {amount} is due on {date}. You can pay from the link here.”
- On the due date: “Hi {name}, today is the due date for SAR {amount}. If you have any question about the invoice, just reply here.”
- After a delay: “Hi {name}, we noticed SAR {amount} is still unpaid. If you would prefer to split it into payments, let us know and we will arrange it with you.”
You can set the assistant’s tone (formal, friendly or casual) and reply length, and list things it must never say, such as anything that sounds like a threat. The assistant also picks up complaints and urgency in what the customer writes and adjusts its tone. For more on templates, read the WhatsApp message templates guide.
Annoying reminders hurt you. If many customers block or report your number, the template’s quality drops. Watsio pauses a campaign automatically when template quality drops to protect your number, but it is better never to get there.
Installments: when and how to offer them
Some customers want to pay but the amount is too large for one payment. An installment plan turns an overdue amount into clear payments. Before you turn it on:
- Decide who qualifies: for example, amounts above a certain level, or customers with a payment history.
- Decide the number and timing of payments: this is your call, based on your business.
- Write the terms in your policy file: the assistant learns from your uploaded files, so it answers using your terms.
- Each payment gets its own reminder and link: so you do not slip back into manual follow-up.
Sensitive cases go to your team. In the team inbox you see the daily follow-up queue and follow-up tasks, so a customer who disputed an amount or asked for details is not forgotten. See the team inbox. And if you run a call centre on Maqsam, you can call the customer with one click from their profile when a call is needed.
For schools and institutes: tuition fees
Schools are a special case: hundreds of parents and amounts on fixed dates. In Watsio you can:
- Create tuition fees in bulk by class.
- Send parents reminders with a payment link.
- Pull a list of late payers to follow up.
- Send attendance and absence messages from the same number.
Important rules before you start
- Official WhatsApp only: Watsio is built on Meta’s official WhatsApp Business Platform, not a QR code tool. This matters because collection messages go out on approved templates under your business name. Read how to send without getting your number banned.
- Data protection: your data is stored on servers in Riyadh, with tools to export or erase a customer’s data and handle opt-out requests under the Personal Data Protection Law. Read the PDPL and WhatsApp guide.
- Collections are not marketing: do not mix a payment reminder with offers and discounts in the same message.
- Invoice first: customers pay faster when the invoice is clear in front of them. Watsio creates ZATCA Phase 2 invoices from the chat through Wafeq, Qoyod, Odoo or Alostaz. Read ZATCA e-invoices from a WhatsApp chat.
What does collecting on WhatsApp cost?
Cost before VAT
You pay Meta’s fees directly to Meta at Meta’s rates. They are approximate and change quarterly. Marketing messages cost about SAR 0.22 each, which is one more reason to keep reminders separate from offers. Estimate your monthly reminder cost with the WhatsApp cost calculator, see the plans on the pricing page and every feature on the features page.

Common questions
Does the assistant send a payment link without the customer agreeing?
No. The assistant confirms with the customer before any money action, such as sending a payment link or invoice.
What happens if the customer disputes the amount?
The assistant hands the chat to someone on your team with a summary, so they can check the invoice and reply themselves.
Can I offer the customer installments?
Yes. The collections assistant offers an installment plan, and it is best to write your installment terms in the policy file the assistant learns from.
How much does a payment reminder message cost?
About SAR 0.04 per utility message at Meta’s rates for Saudi Arabia, before VAT. You pay Meta directly, and Watsio adds no markup.
Can I send a ZATCA invoice with the reminder?
Yes. If you connect Wafeq, Qoyod, Odoo or Alostaz, the e-invoice is created from the chat and reaches the customer with the payment link.
