Billing & subscribers

Before CoreSync was software, it was our own operational problem. A subscriber list in a spreadsheet. Payment confirmations screenshotted out of M-Pesa messages and matched to names by hand. One engineer who knew the OLT CLI well enough to fix a splitter fault, and everyone else waiting on him when he was offline.

None of that scales past a few hundred subscribers, and none of it survives someone leaving. We kept buying billing tools built for other markets — prepaid mobile, or enterprise telco — that assumed away the parts that actually define running an ISP here: M-Pesa as the primary rail, GPON plant that mixes vendors, and support teams who need to see the network, not just the invoice.

So CoreSync is the tool we wished existed while we were the ones on call. It is built by people who have carried the pager, not just people who sold to whoever does.

How we operate

Principles that show up in the product, not just the pitch

Built by operators

Every screen was argued about by someone who had to use it during an outage first. If a feature does not survive contact with a real fault ticket, it does not ship.

No vendor lock-in

Huawei, ZTE, VSOL — your OLT plant should not decide your billing vendor, and your billing vendor should not decide who you can buy an OLT from next.

Uptime over vanity features

A dashboard chart is nice. A subscriber getting reconnected automatically the second their payment lands is the actual job. We build the second thing first.

Works where M-Pesa works

STK Push and C2B are not an add-on integration for us, they are the default rail — because that is how your subscribers actually pay, not how a Western billing tool assumes they pay.

An ISP that gets sharper with every payment

Every M-Pesa confirmation, every session, every optical reading feeds the same system — so billing, the network and your books never disagree with each other.

Where we work

Nairobi, Kenya

We work from the same city as a lot of the networks running on CoreSync — close enough to sit with an operator's support desk during a bad outage, not just read about it in a ticket.
