Vendor Overbilling in Uniform Services: How to Detect & Stop It

 

Vendor overbilling in uniform rentals happens when suppliers charge beyond contract terms – sometimes intentionally, sometimes by mistake. Issues include hidden fees, inflated loss charges, and missed credits. The solution is a structured invoice audit: review bills monthly, compare them to the contract, and demand credits. One healthcare provider recovered $35,000 in year one by doing just that.

Introduction: Uniform rental programs are vital for industries like healthcare, hospitality, and automotive. But with multi-year contracts, billing errors and hidden charges can quietly drain budgets. The truth: most businesses overpay by 20-40% annually due to vendor overbilling in uniform rentals.

How Vendor Overbilling Happens

  • Intentional examples: hidden surcharges, inflated loss fees, mid-contract increases. 
  • Unintentional examples: system errors, bad inventory counts, missing credits.

Either way, your business pays more than it should.


6 Signs Your Vendor Might Be Overcharging

  1. Annual increases above 3%
  2. Missing or inconsistent credits
  3. Loss charges beyond normal wear-and-tear
  4. Line items that don’t match your contract
  5. “Ghost inventory,” you don’t use
  6. Extra fees (fuel, service, environmental) not agreed to

How to Audit Uniform Rental Invoices

  • Gather documents – contract, invoices, and inventory lists. 
  • Compare invoice to contract – check per-piece rates, prep fees, escalators. 
  • Review credits – make sure returns and damages and credited. 
  • Validate inventory – ensure counts match usage.
  • Track extras – list any fees not in your contract.
  • Document findings – create a table to present evidence.
