NextFi

NextFi Systems is a cloud-based WiFi hotspot billing and management platform for hotspot operators, ISPs, hotels, schools, and businesses that sell or control guest and subscriber internet access.

Key capabilities include:

• Automated billing and payments: creates packages, generates invoices, tracks payments, and supports automatic reconciliation for mobile money and card payments, including M-Pesa, MTN MoMo, Airtel Money, and Paystack (availability varies by country).
• Router and authentication integration: connects to MikroTik and other RADIUS-compatible routers for user authentication, session control, and hotspot access enforcement.
• Access control and monetisation tools: voucher generation (with PDF export), bandwidth limits, data caps, time-based restrictions, and MAC address binding for easier reconnect.
• Operations at scale: multi-site management, analytics and revenue tracking, plus reseller and sub-admin roles on higher-tier plans, and PPPoE support for ISP use cases.

Available via a web-based dashboard (mobile-responsive). The website also mentions a companion mobile app.

Designed for B2B teams running paid WiFi, guest WiFi, campus networks, or ISP last-mile access, including single-location hotspots and multi-branch operators.

Notable for its focus on Africa and Asia with country-specific payment methods and pricing options, and broad compatibility across RADIUS hardware (the site lists MikroTik, Ubiquiti, TP-Link, Cisco, and Huawei). Pricing is free to start with transaction-based rates (Core Rate 3% per transaction, or Flex Rate 1.5% on vouchers and 5% on mobile-money transactions), with enterprise plans offered by custom quote.
