“Our first cost audit with Tam Tam immediately revealed an interesting business case for the bank. Since then, we have also identified the major trends in billing errors, such as inaccuracies in mobile data bundles.

Tam Tam are experts with a no-nonsense approach. They can immediately pinpoint the most important issues that demand greater negotiation control with the suppliers. The Tam Tam team have a pragmatic and flexible approach, and deliverables are always in time. We also highly appreciate their professionalism in contract negotiations.

TelecomExpense Management (TEM) with Tam Tam has proven itself a useful investment even in the long-term. In fact, we double our investment: for every € we spend on this project, we see 2€ in savings.
