Cortex AutoBill vs ISPman — billing depth vs hotspot breadth
ISPman is a capable Kenyan ISP platform with MikroTik management, M-Pesa STK Push, captive-portal hotspot billing, vouchers, and a mobile app. Cortex AutoBill targets PPPoE-focused operators that want the deepest payment reliability — stuck-payment recovery, credit balances, grace periods, and a full audit trail — backed by Africa's Talking SMS.
Why Kenyan ISPs Choose Cortex
Stuck Payment Auto-correction
When a Daraja callback is lost but the subscriber paid, Cortex queries the M-Pesa transaction status API and reconciles automatically — revenue is never left in limbo for manual follow-up.
Credit Balance & Grace Periods
Overpayments carry forward as credit and apply automatically on renewal, while a configurable grace-period engine reduces involuntary churn before suspension fires.
Full Audit Logging
Every admin action is recorded immutably for accountability and dispute resolution — important as your team and subscriber base grow.
