About the Company

inSync Staffing

We recognize the VMS program management team is our customer and needs to be serviced with integrity, so we built and continue to improve upon our delivery methods as we strive to provide the highest quality service possible. inSync Staffing’s management team recognized ten years ago the inevitable changes to the staffing industry being brought about by technology and the growing trend of Fortune 1000 corporations to outsource management of their contingent workforces to meet compliance and cost control goals. Rather than swim upstream against the changes, inSync Staffing has embraced MSP and VMS programs as our customers, not competitors. We asked program managers how they want to be serviced.

Our delivery model allows us concentrates our resources on how to best supply candidates in a very competitive MSP/VMS program environment.
