Reminders that get paid
Name the bill, the exact amount and the due date; say how to pay; keep it short. Move from polite to firm to final as the bill gets older, and send it where the party actually reads — WhatsApp.
With Cashflow OS your overdue parties, their bills and statements come straight from TallyPrime, and the reminder goes out with the party's statement from the app. Read our collection guides.
Questions people ask
Which tone should I use?
Start polite a few days after the due date, go firm after two or three weeks, and keep the final notice for long-overdue bills. Most parties pay after a clear, friendly reminder with the exact amount and invoice number.
Can I send it from my business WhatsApp?
Yes. The button opens WhatsApp with the message ready; pick the party's chat (or enter their number) and send it from your phone or WhatsApp Business.
Can reminders go out automatically?
In Cashflow OS, yes: outstanding comes from your Tally, and reminders with the party's statement go out on WhatsApp from the app.
