Yes. For most commercial tenants paying CAM charges, running an audit pays for itself many times over. The math is straightforward once you see the numbers side by side. Here it is.
What an Audit Actually Costs
Traditional CAM audits, the kind performed by CPA firms or specialized audit shops, typically run between $3,000 and $15,000. That price reflects billing rates for accountants who manually review your lease, pull reconciliation backup, and build out a line-by-line comparison. For tenants with very large CAM bills (think $500,000 or more per year), that cost can be worth it. For a restaurant or medical office paying $40,000 in annual CAM charges, it often isn't.
CAMAudit costs $179 per audit. The tool processes your lease and reconciliation documents, runs 20 detection rules, and flags every overcharge with a calculated dollar amount. The break-even on a $179 audit is roughly $350 in overcharges recovered. Anything above that is net savings.
That bar is easy to clear. Very easy.
How Often Are There Actually Errors?
Tango Analytics, a lease administration research firm, found that 40% of CAM reconciliations contain billing errors. PredictAP, which analyzes commercial real estate payment data, estimates that CAM-related billing discrepancies represent $10 to $15 billion in annual revenue leakage across US commercial tenants.
These aren't small properties or unusual leases. The errors show up in strip malls, office parks, medical buildings, and industrial warehouses. They show up in leases drafted by sophisticated landlords with experienced property managers.
The most common errors our detection engine flags are management fee overcharges, pro-rata share errors, and expenses that your lease explicitly excludes being billed anyway. None of these require bad intent on the landlord's part. Many are genuine mistakes in complex annual calculations. But you still pay them if no one checks.
What Tenants Typically Recover
Specific recovery amounts vary widely by property type, CAM bill size, and lease terms. What the research consistently shows is that when errors exist, they are rarely trivial.
A management fee overcharge of 1% on a $2 million expense pool adds $20,000 to your bill. A pro-rata share denominator that's 3% too low means you're absorbing 3% more than your share of every CAM line item. On a $150,000 annual CAM bill, that's $9,750 per year, and it compounds if no one corrects the denominator.
The dollar impact on your specific situation depends on your lease terms, your landlord's calculation methodology, and how long any error has gone uncorrected. That's exactly what an audit is designed to surface.
The Dispute Window Problem
Here's where waiting becomes expensive.
Most commercial leases include an audit rights clause that sets a deadline for disputing reconciliation charges. Thirty days is rare but it exists. One hundred eighty days is common. Twelve months is the outer edge of what most landlords will accept before asserting the dispute right has expired.
Once that window closes, the error is locked in. You can't recover it. If an overcharge ran for three years and you missed the window on years one and two, you're only chasing year three.
I built CAMAudit specifically because the dispute window is the kind of deadline that sneaks up on tenants. You receive a reconciliation statement in April, you're focused on running your business, and suddenly it's October and you've forfeited the right to challenge a $12,000 billing error.
Running an audit as soon as you receive the reconciliation statement keeps all your options open. It takes less time than you'd expect.
Who Gets the Most Value From an Audit
Some tenant situations make the cost-benefit case more obvious than others.
Your annual CAM charges are above $30,000. Below this threshold, the errors still exist, but the absolute dollar recoveries are smaller. Above it, even a 5% overcharge justifies a $179 audit immediately.
Your CAM bill increased significantly year-over-year. A jump of more than 5-8% in a single year, especially in a period of stable occupancy, is worth scrutinizing. It can reflect legitimate expense increases or a calculation error that compounds your baseline.
You have a CAM cap in your lease. CAM caps, which limit year-over-year charge increases to a fixed percentage, are one of the most commonly violated lease provisions because enforcing them requires tracking the calculation across multiple years. If your lease has a cap and you haven't verified it's being honored, the probability of an overcharge is high.
You have multiple locations. Each property has its own reconciliation, its own expense pool, and its own landlord. The more leases you're managing, the harder it is to give each one the attention an error check requires.
You're in your final two to three years of a lease. Landlords sometimes accelerate deferred expenses toward the end of a lease term. Auditing your last few reconciliation statements before lease expiration or renewal is a good defensive practice.
What Happens If You Skip It
Nothing, possibly. Some reconciliations are accurate.
But if there's an overcharge and you skip the audit, you pay it. If the overcharge persists into future years and you never flag it, you keep paying it. If the dispute window expires, you lose the legal right to recover it.
The realistic downside of auditing and finding nothing is that you spent $179 and confirmed your reconciliation is clean. That's not a bad outcome. Knowing your CAM charges are accurate is useful information, especially before a lease renewal negotiation.
The realistic downside of not auditing when there is an error is measured in hundreds or thousands of dollars per year, paid to a landlord who may not even know the calculation is wrong.
How to Run One
Upload your lease and CAM reconciliation statement at camaudit.io/scan. The tool runs your documents through 20 detection rules covering management fees, pro-rata share, CAM caps, gross-up provisions, base year errors, excluded services, and more. You get a full report showing every flag, the dollar amount at stake, and a dispute letter draft you can send to your landlord.
The scan is free to run. You pay $179 to unlock the full report and dispute letter draft if the results show overcharges worth acting on.
If nothing is flagged, you owe nothing and you have confirmation your reconciliation is clean.
