ISP Billing Software for Indian Broadband Operators
XIMS is a complete ISP billing and OSS/BSS platform built for the realities of Indian broadband — GST-compliant invoicing, UPI-first payments, native MikroTik integration, GPON/EPON OLT control, and cable TV / MSO support on a single subscriber record. Over 2 million subscribers are managed on XIMS across India, the Middle East, Southeast Asia, Africa and the United States.
Why Indian ISPs choose XIMS over Iconwave, H8 and Splynx
India runs broadband differently. GST rules, UPI dominance, mixed FTTH-and-wireless deployments, MSO billing alongside data, and a regulatory environment that demands audit trails — most global ISP billing software is adapted to these realities; XIMS was built for them. The platform's 408+ dedicated controllers across 289 database tables model the complete ISP domain end to end, including the constructs unique to Indian operators.
GST-compliant invoicing
CGST, SGST and IGST applied per place-of-supply logic. HSN/SAC codes, e-invoice portal compatibility for operators above the threshold, TDS handling, credit notes and proforma invoices. Built in, not bolted on.
UPI-first payment stack
14+ integrated Indian payment gateways including Razorpay, PayU, CCAvenue, Paytm, PhonePe, Instamojo, BillDesk, GetePay, Easebuzz, AblePay, AggrePay. All major UPI flows supported. Operators choose their own gateway — no platform lock-in.
FTTH + wireless + cable TV
Mixed-technology operators (GPON fiber, MikroTik wireless, cable TV MSO) manage every subscriber on one record. Unified billing across services. The triple play module is designed for Indian MSOs converging broadband, IPTV and cable.
