VMS & MSP
Written by the NextCrew team
Definition
A VMS (vendor management system) is the software a client organization uses to buy contingent staff from its approved staffing agencies. The client or its MSP posts job orders in the VMS, agencies submit candidates through it, and approved time and invoices are processed in it, so every order, rate and hour sits in one system.
In practice
For a staffing agency, the VMS is where client work arrives and where the rules are enforced. Each program gives your team a login, a set of required fields and limits such as how many candidates you may submit per order. Orders are often released to agencies in tiers, and every agency in a tier sees the order at the same moment, so speed to a qualified submittal matters.
After a placement, hours are entered or confirmed in the VMS and approved by the client. Many programs generate the invoice from that approved time and deduct a program fee before paying the agency. Keeping your own timesheets and invoices matched to the VMS is what gets you paid on time.
Example
A hospital posts a per diem ICU shift in its VMS with a $60 bill rate. Five agencies in the first tier receive it at once. The agency that submits a qualified, credentialed Crew Member first usually wins the shift, and is paid on approved hours minus the program fee.
