Automatic Service Reminder for Service-Based Businesses

I've been using MyBillBook for the last 2 years for BroMotive Garage, and I have a feature suggestion.

Currently, we can manually enter the Next Service Date/Km while creating an invoice. However, customers usually don't reopen their old invoices to check when their next service is due.

It would be great if MyBillBook could automatically send a WhatsApp or SMS reminder to the customer on the Next Service Date that we have already entered.

For example:

1-We manually set the next service date while creating the invoice.

2-On that date, MyBillBook automatically sends a reminder like:

Dear Customer,
Your vehicle is due for its scheduled service. Please visit Bromotive Garage for your next service. Thank you!

This would work just like the existing Payment Due Reminder, but for service reminders.

It would help garages and other service-based businesses increase repeat customers, improve customer retention, and eliminate the need to manually call or message every customer.

I hope the MyBillBook team considers adding this feature. It would be a valuable addition for all service-based businesses.
