How does WhatsApp invoice dispatch work?

NexPay connects to official WhatsApp Cloud API endpoints. When you create an invoice, you can dispatch it in one click with your company branding, a formatted PDF document, and a direct clickable portal link with LankaQR and card payment options.

Can my customers pay directly using LankaQR?

Yes! NexPay generates standardized EMVCo dynamic LankaQR codes compliant with LankaPay standards. Customers can scan the code using ANY Sri Lankan mobile banking app (BOC, Commercial Bank Q+, Sampath Vishwa, FriMi, Flash, Genie, iPay) to complete instant bank settlements.

Does NexPay include a physical Point of Sale (POS) counter terminal?

Yes! NexPay Enterprise includes a dedicated browser-based POS terminal mode engineered for retail shops, supermarkets, and wholesale counters with barcode scanning and thermal receipt printing.
