The billing system your network actually runs on.
Everything an internet provider needs to sell, bill, collect, support and grow — in one platform, developed entirely in-house, priced so it works for both of us.
Live & in production
The full CoreSync ISP site lives at coresync.africa. Client systems run on coresyncisp.com — each ISP gets its own subdomain and can point a custom domain at it.
The affordable ones didn’t work. The ones that worked weren’t affordable.
That was the feedback we kept hearing from our own ISP clients. So we set out to build the option that shouldn’t have been missing: a billing system with all the essential features internet providers need, at a price that lets a growing network actually use it.
Because it is developed fully in-house, we add features and enhancements based directly on client feedback — the platform grows with the networks running on it.
What you get on day one.
A system your team gets comfortable with fast.
Simple, interactive and clearly labelled, reachable at your own assigned URL in a single click. Your clients get a branded landing page where they can browse your packages, and tapping Enquire opens their call app pre-filled with your support number.
The whole thing is fully responsive, so neither your staff nor your subscribers are stuck waiting until they’re back at a laptop.
Your clients’ landing page
Packages, pricing and branding are entirely yours to define. Example figures shown.
Gateways supported
Every transaction is stored against its gateway, and monthly sales analytics are generated automatically.
Money in, account redeemed, no one touching anything.
The system integrates with the gateways your customers already trust — M-Pesa, Airtel Money, MTN MoMo, Stripe and Flutterwave — so subscribers pay however they prefer, wherever they are.
Payments appear within seconds of confirmation, are written to the database against the right gateway, and the subscriber’s account redeems itself automatically. Accounts disconnect and reconnect on their own schedule too.
- Full payment transaction history
- Automatic disconnection and reconnection
- Monthly sales analytics and trend reporting
Message the affected node, not your entire customer base.
Organise subscribers into network nodes so that when something goes down, the notice reaches exactly the people it concerns — clear, targeted and professional, instead of a blanket SMS that worries everyone else.
The platform connects to virtually any SMS gateway — Advanta, Onfon, Africa’s Talking, Twilio, Infobip and others — and ships with predefined templates for common messages plus cyclical templates for recurring notices like payment reminders and scheduled maintenance.
- Automatic email and SMS reminders
- Subscriber grouping by node, package or location
- Predefined and recurring message templates

Role-based access
- Administrators — full access to every page and function
- Technicians — network tools, financial data hidden
- Support staff — tickets and customers, no manual subscription opening
- Finance — payments, reconciliation and reporting
Permissions are set per user, per item — not by a fixed template.
Give each person exactly the access their job needs.
Create as many user accounts as you need with customised rights, so a technician never sees the finances and support staff can’t open a subscription by hand.
Beyond billing, there is a full CRM to help you grow and keep the customer base you already have.
- Sales pipeline & lead tracking
- Targeted SMS & email campaigns
- Ticketing with time-to-resolution
- Complete customer history
- Follow-ups & overdue reminders
- Customer segmentation
- Support performance reports
- Call centre support
Try it properly first. Migration is on us.
We provide a fully functional demo where your team can explore the system freely without any risk of interfering with live data. It is completely free and there are no deployment fees — the point is that your staff gain confidence before going live.
Our technical support team also runs personalised one-on-one demonstrations on whichever virtual platform you prefer, so every member of the team understands how to use it.
Migration is fully handled by our team and typically takes one to two days. Give us a deadline — we’re confident we’ll beat it.

Before you ask.
How much does it cost?
Pricing depends on the size of your network, the number of gateways or routers involved and the services you need alongside it. Tell us roughly how many subscribers and routers you run and we’ll come back with a straight figure — no obligation attached to asking.
Is the demo really free?
Yes. The demo is fully functional, free, and requires no deployment fee. It is deliberately separate from live data so your team can click everything without breaking anything.
We’re already on another platform. How hard is moving?
Our team handles the migration end to end. It typically takes one to two days. We also help with the surrounding setup — integrating M-Pesa, configuring automatic connection and disconnection, and the other pieces that make the transition seamless.
Can it handle more than one router?
Yes — the system supports multiple MikroTik routers under a single account, which is the usual reason providers outgrow cheaper platforms.
Which SMS gateway do we have to use?
Whichever you like. The platform is built to integrate with virtually any SMS gateway — Advanta, Onfon, Africa’s Talking, Twilio, Infobip and others — so you can keep your existing provider and rates.
Do you add new features?
Regularly. The system is developed fully in-house, and enhancements come directly from client feedback rather than a roadmap set somewhere else.
