Frequently Asked Questions

Got Questions? We've Got Answers.

Is the 7-Day Free Trial truly free without credit card? ▼

Yes, 100%! When you sign up, you get instant unrestricted access to all Pro features—including 4 PDF themes, WhatsApp dispatch, GSTR-1 exports, and unlimited bills for 7 full days. No credit card or upfront payment is needed.

How does the WhatsApp QR feature send messages for ₹0? ▼

OpenBill Pro uses modern QR-session technology (OpenWA). You simply scan your WhatsApp web QR code once from your phone. Invoices are dispatched directly from your own WhatsApp number, completely bypassing Meta official API conversation fees!

Will I be charged 2% MDR on customer UPI payments? ▼

Never! OpenBill Pro embeds dynamic NPCI compliant UPI deep links directly into your invoices. When customers scan with Google Pay, PhonePe, or Paytm, the money settles directly into your own bank account with 0% gateway deductions.
