A property manager called us ready to process a $2,000 overtime invoice. Standard procedure: pull the credit card, pay the bill, move on. But something about the charge prompted a question, and our team pulled up her contract.
The overtime services were already covered. The agreement had been in place since 2004. She had only been at the company for one year and had never read it. The invoice was an office billing mistake, not a legitimate charge.
"Who knows how many other invoices I've already paid," she said.
This happens constantly. Property managers inherit contracts from predecessors, receive invoices that look official, and pay them without verification. The elevator company isn't necessarily acting in bad faith. Billing systems auto-generate charges. Human review is minimal. Mistakes flow through. Your job is to catch them before the payment clears.
Why Billing Errors Are So Common
Three factors create the environment for billing mistakes.
First, contract inheritance. When you take over a building, the elevator agreement is usually years or decades old. The person who negotiated it is long gone. The coverage details exist only in documents nobody reads unless something goes wrong.
Second, dense language. A 20-year-old maintenance contract was written by lawyers to protect the elevator company, not to inform you. Coverage descriptions are buried in legal phrasing. Exclusions hide in appendices.
Third, automated billing. Service tickets generate invoices automatically. If a technician codes a visit incorrectly, the system generates a charge. Nobody at the elevator company is deliberately reviewing whether your specific contract covers that specific service.
The result: legitimate-looking invoices for work that should have been included. Not fraud. Not scams. Just systemic billing friction that costs you money when you don't verify.
The Five Most Common Billing Errors
1. Overtime Charges on Full Maintenance Contracts That Include OT
Many Full Maintenance agreements include overtime coverage. Some cover "all hours." Others cover "regular business hours only." The distinction matters enormously.
Check your contract for language about service hours. If your FM agreement covers 24/7 response, any invoice for overtime labor should be questioned. The technician was covered. The billing system didn't know.
2. Testing Costs on Contracts That Include Annual Inspection
Annual safety inspections are required in most jurisdictions. Some contracts include inspection coordination, technician preparation, and associated testing. Others exclude these entirely.
When you receive a bill for "annual test preparation" or "state inspection coordination," verify whether your contract includes regulatory testing. This charge can run $1,500-$3,000 and is often covered without the property manager realizing it.
3. Repair Charges for Items Covered Under Full Maintenance
Controller boards can cost $8,000-$12,000. Door operator upgrades run $20,000-$23,000. On a genuine exam contract, these are legitimate billable items. On Full Maintenance, they should be covered.
The dispute usually centers on definitions. The company classifies a component as "beyond normal wear" or "damaged by misuse." The contract language matters. If you have FM coverage, push back on any major component bill until you see the contract clause that excludes it.
4. Travel or Trip Charges When Monthly Visits Are Contracted
Some contracts include a set number of monthly visits. When a technician shows up for a scheduled visit and bills a separate trip charge, something is wrong.
Look for line items labeled "travel," "trip fee," or "dispatch charge" on invoices for routine maintenance visits. If your contract guarantees monthly service, travel to provide that service should not appear as a separate charge.
5. Emergency Surcharges on Routine Callbacks
True emergencies, entrapment rescues with people trapped in the car, warrant expedited response. But not every callback is an emergency.
When an elevator is out of service with no entrapment, and you receive an "emergency response" surcharge, verify whether the situation qualified. A broken leveling system on a Sunday afternoon is inconvenient, not emergent. The billing should reflect that distinction.
Contract Coverage Checklist
Before paying any questionable invoice, answer these questions:
What contract type do you have? Full Maintenance versus Oil & Grease changes what's covered entirely. FM covers parts and labor. O&G covers maintenance visits only.
What are the explicit exclusions? Even FM contracts exclude certain items. Common exclusions include vandalism damage, code upgrades, telephone equipment, and cab finishes. If the invoice item is on your exclusion list, the charge is likely valid.
What hours does your coverage include? "24/7 coverage" means all hours are included. "Regular business hours" means evenings and weekends are billable. Know which you have.
What does your contract say about callbacks? Some contracts include unlimited callbacks. Others cap the number or exclude "user-caused" calls. The language determines whether a specific callback should have been covered.
The theme: know your contract before the invoice arrives, not after.
How to Dispute Properly
When you identify a questionable charge, follow this sequence.
Step 1: Find the specific contract clause. Don't call and complain generally. Identify the exact section that covers (or should cover) the work billed.
Step 2: Put it in writing. Email, not phone. Create a paper trail. Phone conversations are deniable. Written requests require written responses.
Step 3: Request itemization. Ask the vendor to explain, in writing, how the charge complies with your agreement. The phrase that works: "Please reference the contract section that allows this charge."
Step 4: Escalate if necessary. Billing departments follow scripts. Account managers have authority to adjust. If the billing team stonewalls, move up the chain.
Document everything. The companies that correct billing errors fastest are the ones dealing with property managers who have their paperwork in order. For more on hidden fees in elevator contracts, see our full breakdown.
Prevention: Know Your Contract
The $2,000 invoice story has a simple lesson. The property manager almost paid because she had never read her agreement. Once she knew what was covered, catching the error took seconds.
Here's how to prevent billing mistakes:
Digitize your coverage. Create a simple one-page summary: what's IN, what's OUT, what hours are covered, what triggers extra charges.
Review invoices against the summary. Monthly, before payment, compare line items to your coverage sheet. Flag anything not on the IN list.
Keep the contract accessible. When questions arise, you should be able to find the relevant clause in minutes, not hours.
The elevator company has your contract on file. They know what's covered. When you know too, billing errors stop slipping through.
