In-house agency
You build your own staffing operation — recruiting, credentialing, and deploying clinicians you employ. Maximum control, and a real operational commitment.
Run the program yourself, or have someone run it for you
Both work. They fail for different reasons, and the choice usually comes down to something no vendor will ask you about: whether you have the internal capacity to govern a program week after week, not just to stand one up.
Definitions first
These are not the same decision
People use these three terms interchangeably and they are not interchangeable. Getting the vocabulary straight removes most of the confusion.
MSP
A vendor manages the whole contingent program for you: suppliers, rates, compliance, and reporting. A service, not software.
VMS
The software the program runs on. You can buy it without an MSP and manage the program yourself. Buying the tool and expecting the service is the most common mistake here.
All three defined in the glossary, alongside vendor-neutral and master supplier.
The comparison
What you are trading
In-house program, VMS only
- Control is total — you set rates, choose suppliers, and own every relationship
- Cost is lower on paper, because there is no program fee
- Requires dedicated people to govern it, not a fraction of someone's role
- Fails when the person who ran it leaves, or when rate discipline quietly erodes through exceptions nobody logged
- Best for systems with real workforce operations capacity and the headcount to keep it staffed
MSP
- Control shifts to governance — you set the rules, the MSP enforces them
- Cost includes a program fee, usually offset by rate discipline and consolidation
- Requires an internal owner, but a much smaller one
- Fails when the MSP is not genuinely neutral, or when nobody on your side reads the reporting
- Best for multi-site systems with many suppliers and no single view of spend
Ask this
The neutrality question decides most of it
If you go the MSP route, the single question that matters is how vendor neutrality is structurally enforced — not whether it is claimed. Nearly every MSP describes itself as neutral. Far fewer can explain the mechanism that stops their own clinicians getting first look at your requisitions.
We are an agency that also runs MSP programs, which means you should ask us this harder than you ask anyone. Our answer is in the scorecard, including the parts where we score ourselves imperfectly.
- How is neutrality enforced? Ask for the mechanism, not the claim.
- Can incumbents stay? Ripping out suppliers who perform well is disruption without benefit.
- Who owns the data? If leaving means losing your own spend history, you are not really free to leave.
- What is the exit? A program you cannot unwind is a dependency, whatever the contract calls it.
Client FAQ
Before you go to RFP
The questions that come up once the models are understood.
Yes, and that is usually the strongest configuration. The pool covers baseline demand, the MSP governs what is left, and agency use gets reported as an exception rather than a default. Our float pool work is priced as a fixed fee precisely so the two do not conflict.
It should not. Suppliers who perform well can be retained on the program rate card. Wholesale replacement creates disruption and rarely improves fill, which is why we treat incumbent retention as the default rather than the exception.
Only if you have someone whose actual job is running the program. The software gives you visibility; it does not chase a supplier, enforce a rate card, or escalate an unfilled requisition on day nine. Those are people, not features.
Typically a quarter for a mid-sized system, longer where integrations with time and attendance or ERP are involved. Anyone quoting weeks is describing a software switch-on rather than a program.
Ask about the exit before you sign, and make sure your spend and supplier data comes with you. We would rather lose a program cleanly than hold one through switching costs.
