What We Do


Are you certain your telecom services are right for your business? Are your contract commitments being managed to avoid either shortfall penalties or over subscription fees?  Does your team have the time to manage the telecom life cycle?

Our experienced team brings your team an independent resource able to support your business with audit cost benchmarking, contract analysis, competitive solicitations, implementation and ongoing expense management.

Our Services


Our Telecom Expense Management (TEM) services are offered as an outsource of our client’s bill payment process. We do not sell or license software styled to this task, rather we fully assume the role of the corporate telecom expense processing team.

As such we will receive, log, validate, allocate, and if need be
dispute all invoices associated with IT Services…
