Short answer: ISPbox publishes $1.00 per subscriber a month for the first 50, $0.40 from 51 to 500 and $0.30 above 500, with the count rounded up to the nearest 10 and a $25 monthly minimum, plus a 7-day free trial.

The two platforms at a glance
ISPbox says it works with MikroTik, Cisco, Huawei and any RADIUS-capable router, with deep MikroTik integration for PPPoE, hotspot and address lists. Its site lists billing, a FreeRADIUS GUI, reseller management, hotspot and captive portal, a network map, an AI assistant and a client portal, card payments and autopay through Stripe, and PayPal. It offers free migration from Splynx, UISP, Sonar, SAS4 and others, and says more than 300 ISPs use it.
Iterative Billing is a cloud ISP billing and OSS/BSS platform with built-in FreeRADIUS and CoA, MikroTik RouterOS v6 and v7, Huawei GPON OLT automation, TR-069, NOC monitoring and AI agents. It collects M-Pesa, MTN MoMo, Airtel Money, Paystack, Flutterwave, Pesapal and WaafiPay payments into the operator's own merchant accounts. Outside Kenya it charges $0.135 per active PPPoE or Static IP customer a month, capped at $45 up to 500 customers, $90 up to 1,000 and $360 above that, plus 2 percent of collected hotspot revenue capped at $27 a month up to $5,400 collected and $45 above it, with a $9 monthly minimum and a one-time $9 account fee. Optional add-ons are billed on top: every add-on together is $71 a month in the Legacy Partner bundle, with OLTs at $10 each.

Monthly platform charge from each vendor's published US dollar rates, before taxes or add-ons. ISPbox's figures apply its graduated rates to the count rounded up to the nearest 10. Iterative Billing's optional add-ons, such as NOC Monitor at $10 a month or OLT management at $10 per OLT, are not included; every add-on together adds at most $71 a month plus $10 per OLT.
Routers, payments and trials
ISPbox supports Cisco, Huawei and other RADIUS-capable routers alongside MikroTik; Iterative Billing's router integration is MikroTik RouterOS v6 and v7, plus Huawei GPON OLTs for fibre. ISPbox's site names Stripe for cards and autopay, and PayPal; Iterative Billing collects M-Pesa, MTN MoMo, Airtel Money, Paystack, Flutterwave, Pesapal and WaafiPay into your own merchant accounts. ISPbox's 7-day trial is longer than Iterative Billing's 3-day trial for approved networks. Both offer free migration help.
Which should you choose?
If your core runs Cisco or Huawei routers, or your subscribers pay by card through Stripe or PayPal, ISPbox fits that network. If you run MikroTik and your subscribers pay by mobile money, Iterative Billing costs $45 a month at 500 subscribers against ISPbox's $230, and includes RADIUS, hotspot billing and the customer app; the RADIUS billing server page covers the AAA side. Apply for Iterative Billing at billing.iterativebilling.com/register (approved networks get a 3-day trial), and the caps are on the pricing page. ISPbox figures are from its published pricing as of 6 November 2026 and may change. We keep the same date-stamped comparisons for Splynx, Centipid and the other platforms on the alternatives page.
