Send the bill as a PDF on WhatsApp straight from the billing screen, and switch on automatic reminders that go before and after each credit bill’s due date and stop the moment the customer pays.
Why WhatsApp works for shops
Your customers read WhatsApp within minutes. A paper bill gets lost; a WhatsApp bill stays on their phone, which means fewer "please send the bill again" calls and fewer disputes about what was bought.
Sending the bill
The best setup sends the same designed bill you print — logo, GST details and all — as a PDF or image, with one tap after saving the sale.
Payment reminders that do not annoy
- A gentle note a few days before the due date.
- A reminder on the due date, with the amount and bill number.
- A follow-up a few days after — then stop.
- Stop at once when the customer pays, so nobody gets chased for a paid bill.
Example: Murugan Stores owes ₹12,450 on bill INV/0412, due 20 Nov. They get a note on 17 Nov, on 20 Nov, and — only if still unpaid — on 25 Nov.
Respect customers who ask you to stop. Good software skips numbers that have opted out.
In Billman
Billman sends your designed invoice on WhatsApp as a PDF or image. For dues you can send a one-off reminder from the bill, a bulk reminder to all debtors, or switch on Automatic payment reminders — WhatsApp, SMS or email around each due date, stopping once the bill is paid and skipping opted-out numbers.
