Number masking is billed from a prepaid INR wallet at Rs 1.50 per masked minute, in 60-second pulses with a 1-minute minimum, plus the monthly rental of each virtual number (Rs 499 for a mobile number, Rs 449 for a landline). There is no per-seat licensing. Top up with Razorpay, get a GST invoice for each top-up, add your GSTIN for Input Tax Credit, and track your balance from the dashboard or the billing API. When the balance is too low, calls are blocked cleanly instead of running up an overage. All prices exclude 18% GST.
