Billing & subscribers

Plans, payments, RADIUS and disconnection in one loop: a lapsed payment suspends the session, an M-Pesa payment restores it — no spreadsheet, no manual switch-off, no argument about who paid.

What it does

Billing Engine, in specifics

PPPoE / RADIUS billing

FreeRADIUS-backed authentication with live sessions, speed profiles enforced the moment a plan changes, MAC binding and CGNAT-aware pools.

Static IP billing

Fixed-IP subscribers billed by plan rather than session — public-IP add-ons and mixed static + PPPoE fleets on the same account.

M-Pesa built in

STK Push and C2B on your own paybill, matched to the subscriber by account reference first, applied idempotently so a retried callback never double-credits.

Expiry becomes action

Expiry doesn't sit in a report. It suspends the session, notifies the subscriber, and reverses itself the moment payment lands — reconnection in seconds, not shift handovers.

Reminders that collect

SMS renewal reminders before expiry, receipts on payment, and outage notices — sent to exactly the audience each event concerns.

Migration-grade import

Bring thousands of subscribers from spreadsheets or another platform in one streamed, batched import with per-row validation — built for cutover day.

Under the hood

For the reader who wants the details

The payment loop

M-Pesa Daraja (STK Push + C2B) · wallet · invoices

Payments match by account reference first, then fall back to phone number — so a subscriber paying for a relative's account still reconciles.
Every payment applies exactly once, even if Safaricom retries the callback — idempotency is enforced at the application layer, not by hoping.
Partial payments follow your policy: hold in wallet or extend proportionally — your rule, applied consistently.

The enforcement loop

FreeRADIUS · MikroTik and standards-based BRAS

Suspend and restore are tied directly to billing state — no NOC ticket to disconnect a non-payer, no 2 a.m. call to reconnect one who paid.
Speed profiles apply the moment a plan changes, without re-provisioning the CPE.
Live session view per subscriber: IP, uptime, throughput — the support answer is on the screen before the subscriber finishes the sentence.

How it's priced

Which plan includes it

Basic✓IncludedKES 30 per user a month, down to KES 26 as you grow Premium✓IncludedKES 45 per user a month, down to KES 39 as you grow

The billing engine is in both plans. Basic is the billing core on its own — PPPoE and static billing, M-Pesa and payments, RADIUS, SMS reminders and the subscriber portal — at KES 30 per user a month, KES 26 above 1,000 users. Premium adds every other module. A user is a subscriber that was active at any point in the month.
