In ApnaComplex, you can send email/SMS reminders to defaulters. You can send a reminder “on demand” whenever you want to send OR you can automate the process of sending a reminder to defaulters.
For on demand reminders, you can go to Reports->Defaulters Report. Filter on the defaulters based on your criteria. Then click the checkbox in first column to select the defaulter to whom you want to send reminders. Then click on the “Send Message” icon in the footer of the table to send the reminder instantly.
You can also go to Income->Member Income->Setup Reminders->Add Reminder. Fill the data and click ‘Send Reminder Now’ button which will send a reminder in next 15 minutes to the defaulters meeting the criteria.
