Frequently asked questions
When should I use the "firm" tone?
Use it once an invoice is significantly overdue and polite/friendly reminders haven't worked — but keep it professional, never threatening.
Can I add a UPI link so they can pay directly?
Yes — enter your UPI ID and it gets included in the message so the customer can pay immediately from WhatsApp.
