Most of Rejlers' assignments in Finland are carried out for privately-owned customers in Industry. The company has a well developed network within this customer group, with many regular customers. Some of the company’s assignments can be characterised as outsourcing from industry, where Rejlers acts as customers’ development departments for processing or automation, for example.
The company also carries out assignments for Rejlers’ other customer groups: Infrastructure, Energy and Construction and property. The organisations ordering these assignments are a mixture of private and public customers at municipal and state level. In Finland too Rejlers has a very high repurchasing frequency, with repeat assignments from the same customers.
Rejlers' five biggest customers in Finland are Fortum, TeliaSonera, Konecranes, Neste Jacobs and RHK (Finnish Rail Administration).
