Hotel properties enter into dozens of vendor relationships — linen services, maintenance contractors, technology providers, amenity suppliers, cleaning services, landscaping, elevator maintenance, and many more. Each vendor relationship represents an ongoing financial exposure that most properties manage without structured oversight.
The result: systematic overbilling that accumulates quietly, year after year, without triggering any obvious alarm in standard financial management. After conducting hotel financial audits across the United States, our team at Bones Hospitality Solutions consistently identifies vendor-related overcharges as one of the highest-dollar findings in engagements at properties of every size.
How Vendor Overbilling Happens in Hotels
Invoiced Prices Above Contracted Rates
The most common form of vendor overcharge is simple price creep — invoice prices that slowly move above the contracted rates over time, either through deliberate escalation or through billing system errors at the vendor end. Without someone systematically comparing invoice prices to contracted rates, these discrepancies persist indefinitely.
In a hotel with $2 million in annual vendor spend, even a 3% systematic overcharge rate represents $60,000 annually in payments above what was contractually agreed. Across the full range of vendor relationships, the aggregate exposure is typically much larger.
Duplicate Invoice Submission
Vendors occasionally submit the same invoice twice — sometimes accidentally, sometimes not. In a busy hotel accounts payable function that processes hundreds of invoices monthly across dozens of vendors, duplicate detection requires systematic cross-referencing that most properties don't have in place. The average property with inadequate duplicate detection procedures is paying some percentage of its vendor invoices twice without ever knowing it.
Short-Delivery Billing
When receiving procedures are informal — when delivery acceptance is handled by whoever happens to be available rather than by someone following a defined verification process — vendors can consistently deliver below the invoiced quantity without detection. Supply deliveries that arrive 5% short of invoiced quantity, routinely accepted without count verification, represent a direct financial loss on every delivery cycle.
Contract Expiration Without Renegotiation
Many hotel vendor contracts are signed once and then managed on autopilot. When contract terms expire or when market conditions change substantially, properties continue paying rates that no longer reflect current pricing — sometimes for years. A vendor audit identifies contract relationships where renegotiation would produce immediate, ongoing savings.
Non-Approved Vendor Purchases
When department-level purchasing operates without central oversight — when managers can source goods and services from whoever offers the fastest delivery, without competitive pricing or vendor approval requirements — the property loses both cost control and procurement integrity. Non-approved vendor relationships consistently carry premium pricing and eliminate volume leverage across comparable spend categories.
What a Hotel Vendor Audit Examines
A comprehensive hotel vendor audit as part of a broader hotel financial audit engagement examines:
- Invoice price compliance: All major vendor invoices tested against contracted rates for the audit period
- Duplicate invoice detection: AP records cross-referenced for duplicate submissions by vendor and invoice number
- Receiving procedure compliance: Verification that delivery acceptance procedures require count confirmation before invoice approval
- Contract currency: Review of all active vendor contracts for expiration, market competitiveness, and renegotiation opportunity
- Vendor authorization compliance: Confirmation that all active vendor relationships have been properly approved through the purchasing function
- Kickback risk indicators: Transaction pattern analysis for signs of inappropriate relationships between purchasing personnel and vendor representatives
Typical Findings in Hotel Vendor Audits
The financial impact of vendor audit findings at hotel and resort properties typically ranges from five to six figures in annual overcharges, depending on the total vendor spend volume and the maturity of existing purchasing controls. Specific findings commonly include:
- Linen and laundry services billing above contracted per-piece rates on a systematic basis
- Technology and software vendor invoices for licenses or services no longer in use
- Maintenance contractor invoices above agreed hourly rates or for uncompleted scope
- Supply vendor pricing inconsistencies between contracted rates and actual invoice pricing
- Insurance and service contract billing discrepancies against policy terms
What Happens After the Vendor Audit
Audit findings create three types of value. First, identified overcharges can often be recovered from vendors — either through credits on future invoices or through direct refund requests with supporting audit documentation. Second, corrected billing procedures and updated contract terms produce permanent ongoing savings. Third, implementation of structured receiving and invoice review procedures prevents future overcharges from accumulating undetected.
Properties that implement the vendor compliance procedures recommended from our hotel audit engagements consistently sustain their savings — not because the procedures are burdensome, but because they're straightforward to maintain once they're properly designed and embedded in the accounts payable workflow.
Taking Action
If your hotel has not had an independent vendor compliance audit in the past twelve to twenty-four months, the probability that you are currently paying above contracted rates on at least some vendor relationships is very high. The question is not whether the overcharges exist — it's how much they're costing you annually.
