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 billing 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 system that revolutionises the industry.

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!
