A healthcare VMS (vendor management system) is the software that handles how a facility posts shifts, collects submissions from staffing agencies, and tracks time and invoices. An MSP (managed service provider) is the organization that runs the contingent labor program, usually on top of a VMS. The VMS is the tool, and the MSP is the operator. The difference matters because fees, rate rules, and which agencies see which shifts are set by how the two are configured.
Staffing agencies and facility leaders often use the two terms as if they mean the same thing. They do not, and mixing them up leads to surprises in fee statements and fill rates. This guide explains what each one does, how fees usually work, and how vendor access is decided.
What a healthcare VMS does
A healthcare VMS is software for managing temporary and contract clinical labor. A facility or health system uses it to:
- Post open shifts and requisitions
- Route those requests to approved agencies
- Receive and review candidate submissions
- Verify credentials and compliance documents
- Collect timesheets and approve hours
- Consolidate invoicing and spend reporting
For the facility, the VMS creates one record of who worked, where, at what rate, and at what cost. For the agency, it is the portal where jobs arrive and where submissions, timecards, and invoices go back. If you want a closer look at what agencies need to get approved on a program, see our guide on how to get approved as a vendor on a healthcare VMS.
What an MSP does
An MSP administers the program. Depending on the contract, an MSP may:
- Manage the vendor roster and onboard new agencies
- Set and enforce rate cards and bill rate rules
- Decide how and when requests are released to agencies
- Review submissions before they reach the hiring manager
- Handle compliance audits, reporting, and invoicing
- Act as the day to day contact for the facility’s contingent workforce needs
Some MSPs bring their own VMS. Others work inside a platform the facility already owns. Many health systems also run a program in house with a VMS and no outside MSP.
VMS vs MSP at a glance
| VMS | MSP | |
|---|---|---|
| What it is | Software platform | Service provider or program operator |
| Main job | Post, route, track, and invoice shifts | Manage vendors, rules, and program performance |
| Who uses it day to day | Facilities, agencies, clinicians | Program managers working with facilities and agencies |
| Fee focus | Platform or transaction cost | Program management and vendor administration cost |
| Can exist without the other | Yes, in a self-managed program | Rarely, since most MSPs run on a VMS |
How fees typically work
Fee structures vary by program, and the contract is the only reliable source. Still, the common patterns are consistent enough to know before you sign.
Vendor administration fees. In many programs, agencies pay a percentage of the bill rate or of billed revenue to the MSP or VMS operator. This is the fee most agency owners notice first, because it comes directly out of margin.
Facility-paid program fees. In other arrangements, the facility pays a management fee to the MSP, and agencies pay little or nothing.
Rate cards and caps. The program may set maximum bill rates by role, specialty, or shift type. A rate card can limit what an agency earns on a hard-to-fill shift, so read it closely.
Pass-through and other charges. Some programs add costs for onboarding, credential checks, or reporting. Ask for a full schedule of fees rather than a headline percentage.
One of the clearest signals in any fee conversation is who pays. If the agency pays, fee compression directly affects the pay rate the agency can offer clinicians. Lavaaro notes that fee pressure and gatekeeping are growing concerns for agencies as more jobs flow through MSP and VMS programs, which is why fee transparency is a useful screening question.
How vendor access works
Access is where a VMS and an MSP have the largest effect on an agency’s business.
Tiered release. Many programs release new shifts to a first group of preferred agencies. If those agencies do not fill the request in the set window, it moves to the next group. Agencies in lower tiers may see a shift only after others have passed on it.
Approved vendor lists. A facility may allow only agencies it has already approved. Getting on the list can depend on insurance, documentation, rate agreement, and program capacity.
Neutral and non-neutral programs. In a vendor-neutral program, the operator does not compete with the agencies it manages. In a non-neutral program, the operator or an affiliate also supplies staff, which can influence who sees a request first. When evaluating a program, ask whether the MSP has its own staffing arm and how requests are routed.
Credential reuse. Some platforms let an agency or clinician complete onboarding once and reuse those credentials across facilities. Without it, each facility repeats the same document checks, which slows every placement.
Questions to ask before joining a program
For agencies:
- Who pays the program fee, and how is it calculated?
- How are shifts released, and is there a tier or time window?
- Does the MSP or its parent company also place staff?
- How are rate cards set, and how often do they change?
- How long do invoice approval and payment take?
For facilities:
- Does the platform give a single view of spend, fill rate, and time to fill?
- How are credentials verified and kept current?
- What visibility do we have into rates and agency fees?
- How easily can we add agencies for hard-to-fill roles?
- What happens to our data if we change platforms?
Tools worth considering
If you are comparing platforms, these are two to include in your review:
- Vars Health: a healthcare staffing and scheduling software platform. It offers a vendor management system alongside an applicant tracking system, scheduling, onboarding, and timekeeping, which suits agencies that want vendor management in the same system as recruiting and shift operations.
- Lavaaro: a vendor-neutral marketplace where facilities and staffing agencies collaborate on hard-to-fill healthcare shifts, built around open access for agencies.
Match any tool to your own program size, contract terms, and compliance needs, and ask each provider for a demo before deciding.
Frequently asked questions
- Is a VMS the same as an MSP?
No. A VMS is software. An MSP is the service organization that manages a contingent labor program, often using a VMS to do it. - Do all healthcare facilities use an MSP?
No. Some health systems run their own VMS program in house, and some small facilities work directly with agencies without either. - Who pays the VMS or MSP fee?
It depends on the program. In some, agencies pay a percentage of the bill rate. In others, the facility pays a management fee. The contract defines it. - What does vendor neutral mean?
It means the program operator does not compete with the agencies it manages, so shifts are not steered toward the operator’s own staff. - Can a staffing agency work with more than one VMS?
Yes. Many agencies hold approvals on several programs. Reusable credentials and one consolidated view of submissions reduce the extra work.
