A WISP billing system is software that helps a Wireless Internet Service Provider (WISP) manage subscribers, internet plans, payments, invoices and network access from a single dashboard. It automates day-to-day operations such as customer onboarding, recurring billing, payment collection and service activation or suspension based on account status.

Most WISP billing systems integrate with networking equipment such as MikroTik, Ubiquiti, TP-Link Omada and RADIUS servers. This integration allows providers to automatically enable or disable internet access when customers make payments or when their accounts become overdue, reducing manual work and improving operational efficiency.

Modern WISP billing platforms also include customer relationship management (CRM), voucher management, support ticketing, usage monitoring, financial reporting, communication tools and integrations with payment gateways. These features help WISPs streamline operations, improve customer service and scale their networks with fewer administrative tasks.

Popular WISP billing systems include Centipid, FreeISPradius, speedradius, Netiva, ISPman, Netpay, Splynx, Powercode and WispMan.
