A healthcare staffing agency places nurses, allied health professionals, and physicians into hospitals, clinics, and long-term care settings, on travel contracts, per diem shifts, locum tenens coverage, or permanent hires. Facilities use them to cover vacancies, census spikes, leaves, and rural gaps that permanent recruiting cannot fill fast enough.

01
How they make money
The workhorse is the hourly bill rate. The facility pays one rate per hour worked, out of which the agency funds the clinician's pay package, payroll costs, housing and meal stipends on travel contracts, liability coverage, and its margin. Travel assignments standardize around 13 weeks with extensions common. Per diem staffing bills shift by shift at higher hourly rates in exchange for zero commitment.
Physician coverage, called locum tenens, prices as a daily or hourly rate, with the agency typically arranging malpractice coverage, travel, and licensing support. Permanent placement fees for hard-to-fill clinical roles usually run as a percentage of first-year salary. Many large health systems buy through managed service programs that standardize rates across all vendor agencies, so ask early whether you are negotiating with the agency or with the program above it.
02
What good ones have in common
Joint Commission certification for staffing. The Health Care Staffing Services certification signals audited credentialing and placement processes. It is voluntary, which is exactly why carrying it means something.
Credentialing finished before day one. License verification, immunizations, background checks, competency testing, and references should be complete and documented before a clinician is submitted, not backfilled after they start.
Clinical leadership on the agency side. A director of nursing or a medical advisor who handles clinical complaints and competency escalations. Without one, quality problems land on your managers alone.
A 24/7 human on call. Healthcare runs nights and weekends. If a clinician no-shows for a Saturday night shift, an answering service is not a plan.
Cancellation terms that cut both ways. Assignments get cancelled by both sides. Fair contracts spell out notice periods and fees symmetrically instead of penalizing only the facility.
03
Red flags
A licensed clinician who can start tomorrow. Speed that skips license verification or competency checks is a liability transfer to your facility. Real credentialing takes days at an absolute minimum.
Stipend structures that game tax rules. Travel pay packages built on inflated tax-free stipends and token wages invite tax problems for clinicians and audits that can disrupt an agency mid-contract.
Rate opacity that breeds mid-contract walk-offs. When clinicians discover a large spread between bill and pay, some leave for a better package. Agencies that churn talent this way leave you re-onboarding constantly.
No professional liability clarity. You need to know, in writing, whose malpractice coverage responds to an incident involving agency staff, and at what limits, before the first shift.
No backfill plan for cancellations. Clinicians cancel assignments; it is a fact of the market. A strong agency quotes its backfill rate and timeline. A weak one just restarts the search while your schedule bleeds overtime.

How the category is changing
The pandemic-era rate spike has unwound. Travel bill rates fell back sharply from their peaks, agencies consolidated, and hospitals are working to shrink agency dependence with internal float pools, per diem apps, and direct-hire pushes. Several states have debated or enacted limits on agency rates and practices, so the regulatory temperature is rising.
The structural story is unchanged: an aging population, clinician burnout, and chronic shortages in nursing and behavioral health keep demand durable even as rates normalize. Interstate licensure compacts keep expanding, which shortens credentialing for multistate nurses and physicians. The agencies winning now compete on credentialing speed, fill reliability, and clinician retention rather than on the boom-era pitch of simply having bodies available.

Frequently asked questions
How much does a healthcare staffing agency cost?
You pay an hourly bill rate covering the clinician's pay package, payroll costs, coverage, and margin. Rates vary widely by specialty, geography, and urgency. Per diem costs more per hour than contract work; permanent placements price as a salary percentage.
What is the difference between travel and per diem staffing?
Travel clinicians commit to a contract, typically 13 weeks, often relocating with housing stipends. Per diem staff pick up individual shifts locally with no commitment, at higher hourly rates in exchange for the flexibility.
What is locum tenens?
Temporary physician or advanced practice coverage. The agency provides a credentialed provider for days to months, usually arranging malpractice coverage, travel, and licensing support, so care and billing continue while you recruit permanently.
How long does credentialing take before a clinician can start?
Typically two to four weeks for a new facility, covering license verification, background checks, immunizations, and competency documentation. Compact licenses and pre-credentialed staff can compress that. Anyone promising a licensed start tomorrow is skipping steps.
Why are agency nurses so expensive?
The bill rate carries wages competitive enough to attract scarce clinicians, plus payroll taxes, stipends, liability coverage, credentialing, and margin. You are also paying for zero long-term commitment, which is the entire point.
Do healthcare staffing agencies place permanent staff too?
Most do, alongside contract work. Permanent placement fees typically run as a percentage of first-year salary, and many agencies will convert a traveler you like into permanent staff for a conversion fee after the assignment ends.
