About Tekton Billing


The Ancient Greek noun is commonly defined as a craftsman; in particular a builder, teacher or engineer.

Our name is a reference to our journey.

Tekton Billing is a family-run business that was born from the joint knowledge and experiences of an existing wholesale telecoms reseller and an existing network-level billing operator.

Both parties had a common goal; to create an innovative, exciting and market leading billing solution that revolutionises the industry.

Our management team has over 100 years of billing experience between them.  You can therefore rest assured that with Tekton Billing, you have some of the most knowledgeable and technically-able minds in the industry housed under one roof!

We have taken the network-level architecture from an existing Enterprise rating engine and developed an intuitive reseller-based platform in-house. It offers a depth of functionality that brings carrier-grade billing to resellers in the channel.

In addition, we have taken the industry-renowned carrier grade customer portal and enhanced its feature set to give our resellers more flexibility and control. In essence, providing all the foundations for the future growth of our partners.

Finally, we have used all our in-house knowledge of telecoms billing to shape the product. We have ensured it successfully overcomes the daily challenges that hold resellers back, thereby promoting their growth.

We are built from every mistake and every success we ever made.

Who We Are

Terry McKeever

Terry McKeever


Terry has a breadth of experience in both the Financial and Telecoms sectors including successful stints at Prudential Corporation, Cable and Wireless and Colt telecom; the latter two performing the role of UK Director for Indirect Channels. In recent years his entrepreneurial flair has come to the fore and he has developed a number of successful business ventures, one notable success being Totility Ltd, which he started in 2005 and sold to Maintel PLC in 2011.

Terry has continued to remain involved in the Telecoms sector in an advisory capacity with a passion for people, customer service and market differentiation, and often finds he can make an impact where others seem to find it impossible to do so.

Privately, Terry has a keen interest in cars, art, family and travel, often choosing to combine all 4 whenever possible!

An Economics graduate from the University of Bath, Charlie began his career in sales & marketing, primarily focusing on the FMCG industry, offering Charlie significant exposure to all areas of the marketing jobs mix.

Charlie’s next career step saw him move into a more customer facing role working for Jutel, an existing wholesale telecoms based reseller where he took the lead in Sales and Account Management. Charlie’s role within Jutel enabled him to become an expert in using the existing Zygo Enterprise Billing system and he has become a pioneer for change, driving the development of new reseller-based platform which we now know as Zoey.

Charlie now leads the Sales and Account Management team within Tekton.

Charlie likes to spend his Saturday’s at Selhurst Park as a keen Crystal Palace season ticket holder!
