About Tekton Billing
Independent, family-run and built by people who have lived with billing.
Tekton is an Ancient Greek word for a craftsman: a builder, teacher or engineer. It sums up what we do. We build the billing platform, we teach our partners to get the most from it, and we engineer better ways of turning complex services into accurate, profitable invoices.
Tekton Billing is the independent UK business behind ZOEY, ZOEY SP and ZOEY Rate. Our developers, billing specialists and support team work side by side, so the people building the platform never lose sight of the people using it.






Independent and Family-Run
UK-Based Team
ISO 27001 Certified
Award-Winning Platform
It Started With a Familiar Frustration
Tekton Billing was born out of frustration with legacy billing systems. Our founders came from the reseller channel, where they saw first-hand how much time went into supplier files, rate cards, manual checks and month-end corrections, and how little flexibility the old platforms offered in return.
We believed there had to be a better way to manage billing in the 21st century. So we built one. Our mission has stayed the same ever since: to develop a market-leading billing platform that transforms the way service providers bill, and delivers real value for every partner we work with.
- Founded by people who have run a reseller business
- Privately owned, with no network or distributor ties
- Our own in-house development team
- A partnership approach from day one


Telecoms Taught Us to Look Beyond the Invoice
An invoice is only the final step. Before it come the supplier records, usage, wholesale costs, charging rules, contract changes and exceptions. Years of hands-on billing experience shaped the way we think about all of them, and it is why we care as much about the operational detail as we do about the finished bill.
That experience now serves telecoms providers, MSPs, ISPs and subscription businesses alike. Whatever you sell, we understand the pressure of getting every bill right, on time, every month, while protecting the margin you have worked hard to earn.
The Values That Guide Us
Our values are not a poster on the wall. They shape how we build ZOEY, how we support our partners and how we work with each other.
Flexible
We break down barriers and adapt to the unique billing needs of every partner, from the suppliers you use to the way you want your invoices to look.
Experienced
Our team brings deep expertise across mobile, SIP, IT and pricing, and we share that knowledge through regular internal training so every partner benefits.
Pioneering
We are not bound by convention. Partners and colleagues help shape new features, and our in-house developers decide how and when improvements are delivered.
Honest
We work with integrity and transparency, keeping partners informed at every step and giving clear, straight answers, even when they are not the easiest ones.
Customer-Focused
We take a partnership approach and act as an extension of your team, from your first demo and migration through to every month-end bill run.
Passionate
We care about making a real difference for our partners, their customers and the wider community, and we go above and beyond for each other too.

Our Next Chapter Builds on What We Know
Our foundation is UK telecoms and MSP billing, and it always will be. Our ambition is wider. The same challenges of usage, recurring charges, supplier costs and customer self-service apply to subscription businesses, metered services and international providers.
With ZOEY for complete billing, ZOEY SP for direct network partners and ZOEY Rate for high-volume rating behind your own systems, we are taking that expertise into new markets while keeping the practical, personal approach that shaped Tekton Billing.
