about tekton billing

About Tekton Billing

Tekton is an Ancient Greek noun that refers to a craftsman; in particular a builder, teacher or engineer.

Our name is a reference to our journey.

Tekton Billing is an independent, privately-funded family-run business, born out of the frustrations of a wholesale telecoms team that thought ‘there must be a better way to bill in the 21st Century’.

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

Charlie McKeever


An Economics graduate from the University of Bath, Charlie began his career in sales and marketing, primarily focusing on the FMCG industry. This offered Charlie significant exposure to all areas of the marketing 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. He has become a pioneer for change, driving the technical development of our 21st century billing platform, ZOEY.

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

I can’t praise everyone enough at Tekton Billing. After getting totally shafted by our old billing company, they went over and above what I expected. Now I am looking forward to a fruitful business relationship. Keep up the great work guys and thank you!
