Wolters Kluwer UK is to outsource its payroll from May.
The firm, which had previously managed its payroll in-house, made the decision to outsource in a bid to cut costs and mitigate risk.
ADP Employer Services will †provide a online system for the firm alongside training and development, absence management, performance management and benefits features.
Eamonn Quinn, project manager at Wolters Kluwer UK, said: "We were keen to find a payroll service that would provide us with dedicated support and ADP fit the brief."
