Datassist
Work Permit Consulting

Employing international staff carries serious risk if left unmanaged

Work permit regulation has changed significantly in recent years and becomes more sensitive every year. Processes that are not handled carefully lead to serious time and financial loss. With 20+ years of experience, Datassist manages the entire process from application to outcome.

Mango

We used to believe that outsourcing would not bring much benefit in retail operations with high turnover and many stores. Datassist changed that perception completely.

At Mango, the accuracy of employee costs and their compliance with international reporting are vital for us. With a team that genuinely understands retail dynamics, Datassist did not simply provide a payroll service; it also gave us clarity and confidence on the financial side.

Today I can say clearly that most of the classic concerns about outsourcing lose their meaning when you work with the right partner.

GKN Automotive

At GKN Automotive, operating within a structure built on global standards, we treat the accurate, timely and fully compliant management of payroll processes in our Türkiye operations as a top priority.

When we started working with Datassist, our most important expectation was a partner that follows complex local legislation closely and can adapt to our global reporting needs. We saw very quickly that Datassist is not just a payroll supplier, but a solution partner that takes ownership of the process and manages it proactively.

Today, entrusting our payroll processes to Datassist has not meant a loss of control; on the contrary, we have gained clearer visibility and greater operational ease.

Yemekhane

At Yemekhane we operate across many locations with high employee turnover. Within such a structure, employee costs are one of the most critical items for budgeting and financial planning.

Today Datassist Forecast is not merely a budgeting tool for Yemekhane; it has become essential support that lets us manage employee costs in a more controlled, predictable and sustainable way.

We would confidently recommend Datassist and the Forecast module to companies with similar dynamics.

Fifteen years is not a period every company can sustain with a single business partner — least of all in a field such as payroll and outsourcing services, which depends on long-term trust. That, in itself, is the clearest sign of mutual satisfaction.

I hope we work together not for 15, but for 20 years and well beyond.
