Invoice factoring and payroll funding are two of the most widely used financing tools for nurse staffing firms, but they work differently. Invoice factoring gives you cash advances on your outstanding healthcare invoices, whereas payroll funding combines financing with payroll processing and back-office support. This comparison explains funding speed, cost, flexibility, and when each option is better for nurse staffing agencies in 2025.
Comparison Table: Invoice Factoring vs Payroll Funding
| Feature | Invoice Factoring | Payroll Funding |
| Primary Purpose | Convert invoices to cash | Finance payroll + handle back office |
| Funding Speed | 24–48 hours (after invoice verification) | Same-day or weekly based on payroll cycle |
| Advance Rates | 85–95% of invoice value | 90–100% of payroll cost |
| Ideal For | Agencies with strong back office | Agencies needing payroll + billing + collections |
| Cost Structure | 1–4% per invoice (tenor-based or flat) | 1.5–3% weekly or bundled service fee |
| Requires Back-Office Team? | Yes | No |
| Scalability | High (invoice-driven) | High (volume-driven) |
| Best Fit | Growing nurse staffing firms | Startups or agencies entering MSP/VMS programs |
Which Option Funds Payroll Faster?
Claim: Payroll funding typically provides faster access to payroll-ready capital than invoice factoring because it advances funds based on current payroll rather than completed invoices.
Evidence:
- Payroll funding advances 90–100% of payroll liabilities immediately once timesheets are approved.
- Invoice factoring advances 85–95% after invoices are created and verified, which depends on timesheet collection and facility approval.
- Nurse staffing firms often run payroll weekly, and payroll funding aligns directly with this cycle.
Implication:
Nurse staffing firms that struggle to create invoices quickly—or rely heavily on MSP/VMS portals—may get faster operational relief from payroll funding.
Takeaway:
If funding speed tied to payroll is your top priority, payroll funding is usually faster.
Which Option Has Lower Costs in 2025?
Claim: Invoice factoring typically has lower total financing costs than payroll funding because fees are tied to invoice age, not weekly payroll cycles.
Evidence:
- Factoring fees average 1–4% per invoice cycle depending on DSO.
- Payroll funding commonly charges 1.5–3% weekly, which compounds over multi-week payment cycles.
- Nurse staffing agencies serving slow-paying hospitals (60–90 days) may pay more under payroll funding because weekly fees accumulate.
Real Example:
- $100,000 in receivables at 90-day terms
- Factoring cost @ 2.5% → $2,500 total
- Payroll funding @ 2% weekly for 12 weeks → $24,000 total
Implication:
When facilities take 45+ days to pay, factoring almost always reduces financing cost.
Takeaway:
If minimizing financial cost is your goal, invoice factoring is usually cheaper for nurse staffing firms.
Which Option is More Flexible for Nurse Staffing Firms?
Claim: Invoice factoring provides greater funding flexibility because it finances every invoice, not just payroll cycles.
Evidence:
- You can factor any volume of invoices (large or small).
- You can fund onboarding, recruiting, workers’ compensation, or additional shifts.
- Payroll funding primarily covers payroll liabilities and associated fees.
- Factoring grows automatically as invoicing grows, creating a scalable cash-flow engine.
Implication:
Agencies planning to add specialties, increase clinician count, or accept larger contracts benefit from funding that grows with revenue—not payroll timing.
Takeaway:
For maximum flexibility and scalability, invoice factoring offers more options.
Use-Case Scenarios
Best for Startups: Payroll Funding
If you are a new nurse staffing agency without a back-office team, payroll funding is ideal because it includes:
- Payroll processing
- Invoice creation
- Collections support
- Tax withholding
- Funding tied to payroll cycles
Best for Growing Agencies: Invoice Factoring
If you already handle your own payroll and billing, invoice factoring supports:
- Rapid hiring
- Larger hospital contracts
- Faster expansion
- MSP/VMS scaling
- Weekly consistent funding
Best for Agencies with MSP/VMS Clients: Payroll Funding
Payroll funding often works better when MSP portals require strict approval processes, because payroll funding providers handle portal operations.
Best for Agencies Focused on Profitability: Invoice Factoring
Invoice factoring maintains lower financing costs long-term, especially with slow-paying hospitals.
Summary Decision Framework
Choose Invoice Factoring If…

Choose Payroll Funding If…
