Every health system leader has heard the same directive from the boardroom this year: get agency spend under control. The instinct is usually to negotiate harder with vendors or cap contract labor hours. Both help at the margins. Neither solves the underlying problem, which is that most health systems have no systematic way to see and deploy the workforce they already employ.
An internal workforce marketplace is the fix. Here is what it actually is, how it works, and what it takes to build one.
What Is an Internal Workforce Marketplace?
An internal workforce marketplace is a technology layer that sits on top of your existing HRIS (Human Resources Information System) and scheduling software, nothing replaced, that matches skills, credentials, and licenses across every department and location so your entire employed workforce can function as float capacity. Instead of each unit or facility managing its own shortage in isolation, open shifts post to your own qualified employees first, wherever they sit in the organization.
The thesis behind this model is simple: most health systems do not have a talent shortage, they have a deployment problem. The nurse who could cover a shift two floors down, or the surgical tech who could pick up an extra shift at the sister facility across town, is already on payroll. She just has no visibility into that open shift, and the health system has no easy way to offer it to her.
Core Components
A working internal workforce marketplace has three parts.
Internal mobilization first. Every open shift is offered to your own employed staff before it goes anywhere else. This is the InternalPool layer: an overlay on your existing systems, not a replacement for them.
A credentialed external bench for the gaps that remain. When internal coverage genuinely cannot fill a shift, a vetted marketplace of independent clinicians, credentialed to your standard and facility-specific onboarded, fills in. This is not a travel agency relationship. Clinicians work directly with your organization, at your rates, without a markup layer.
A path to permanent hire. When a marketplace clinician is a strong fit for your organization long term, the platform should make it simple to convert them to a permanent role, without a hire-away fee working against you.
Implementation Steps
Map your current state. Most systems underestimate how much internal float capacity already exists because it’s scattered across department-level spreadsheets and text threads. Start by cataloging who is credentialed for what, where.
Stand up facility-specific onboarding. Every facility has its own competency requirements, orientation steps, and documentation. A workforce marketplace platform should let you build that onboarding once per facility and apply it consistently.
Launch with your highest-volume gap first. Most systems see the fastest ROI (return on investment) by starting with the unit or shift type that consumes the most agency spend today, then expanding.
Add the external bench. Once internal mobilization is running, layer in credentialed external clinicians for true gaps, rather than defaulting to agency staffing.
Measuring ROI
Four levers matter most: reduction in premium labor spend, reduction in recruiting overhead, reduction in avoidable turnover, and eliminating conversion fees when a flexible worker becomes a permanent hire. Most health systems can model expected savings against these four levers before committing to a platform, using their own current agency spend and vacancy data as the baseline.
The workforce itself is also shifting. A growing share of clinicians, across every license type, want more control over where and when they work. An internal workforce marketplace does not fight that shift. It gives health systems a way to meet it, first with their own employed staff, then with a credentialed external bench when needed, without losing visibility, compliance, or cost control in the process.
