Client background
T-Mobile Poland is one of the largest mobile telecommunications providers in the country, serving over 11 million users.
As a market leader, the company continuously strives to optimize internal operations and improve customer service to maintain its competitive edge. A critical part of this effort lies in equipping sales teams with the right tools to manage customer relationships efficiently.
The Business Challenge: Replacing the old sales stack
T-Mobile’s sales consultants were operating within three separate CRM systems. This fragmented environment led to a series of issues:
- A complex and inefficient sales process
-
Longer onboarding times for new employees
- High risk of downtime when updating functionalities
-
Difficulty in scaling the system to meet growing demand
For a company experiencing dynamic growth, such operational obstacles were unacceptable. T-Mobile needed a future-proof CRM platform that would not only centralize the sales process but also ensure system stability and flexibility during continuous development.
