About CAMAudit
I built CAMAudit to give commercial tenants the same forensic tools that auditors use, without the $5,000 consulting fee. What started as a question turned into a platform that runs 14 detection rules on your CAM reconciliation in under 15 minutes.
The Problem
Landlords control every variable in CAM billing: what gets included, how denominators are set, and when statements arrive. Commercial tenants receive dense annual reconciliation statements with a 90-day window to dispute them.
Traditional audit firms charge $2,500 to $8,000 upfront plus 33% contingency on any recovery. That math only works if you have at least 25 locations. For the vast majority of commercial tenants, no economically viable audit option has existed until now.
According to IREM's Journal of Property Management and Tango Analytics, 30-40% of CAM statements contain billing errors. Most of those overcharges go unchallenged because tenants have no practical way to verify them.
The Solution
CAMAudit runs a full forensic audit in under 15 minutes at a flat fee. Upload your commercial lease and CAM reconciliation statement. Our platform extracts structured data using AWS Textract and Claude AI, then runs 14 deterministic detection rules to identify billing errors with specific dollar amounts.
The iron rule: Claude classifies, Python calculates. AI is used only for data extraction and expense classification. Every overcharge amount is calculated by deterministic Python code, not language model estimation. That makes every finding defensible.
The free scan runs the full pipeline and shows you the total potential recovery. Pay a flat fee to unlock the complete findings and see what a full report looks like. 100% of recovery stays with you.
14 Detection Rules
Each rule targets a specific billing error pattern found in commercial CAM reconciliations. Math-heavy rules (3, 4, 5, 6, 7, 8, 18) use deterministic Python formulas. Classification-heavy rules (1, 2, 9, 10, 11, 12, 13) use Claude to classify expenses against lease terms.
Gross Lease Charges
Detects CAM charges billed under gross leases where CAM is included in base rent.
Excluded Service Charges
Identifies services explicitly excluded from CAM per lease terms.
Management Fee Overcharge
Verifies admin fees against lease-specified percentage caps.
Pro-Rata Share Error
Checks occupancy denominator, anchor exclusions, and square footage calculations.
Gross-Up Violation
Verifies gross-up clauses for variable expenses at specified occupancy thresholds.
CAM Cap Violation
Checks year-over-year increases against lease cap provisions.
Base Year Error
Verifies base year selection, expense inclusion, and calculation methodology.
Controllable Expense Cap Overcharge
Checks controllable expense year-over-year increases against cap provisions.
Insurance Overcharge
Classifies insurance passthrough charges against lease exclusions.
Tax Overallocation
Checks property tax passthroughs for excluded parcels and calculation errors.
Utility Overcharge
Detects utility double-billing and non-CAM utility inclusions.
Common Area Misclassification
Identifies non-common-area costs billed as CAM.
Landlord Overhead Pass-Through
Identifies landlord administrative overhead and internal costs billed as CAM.
Estimated Payment True-Up Error
Verifies that estimated payment reconciliations match actual billed amounts.
Built by Angel Campa, Founder
I am a Principal SDET (Software Development Engineer in Test) by day, and the founder of CAMAudit. My background is in software engineering and quality, not commercial real estate. What I brought to this problem is systems thinking and a deep distrust of processes that rely on manual error detection.
I built CAMAudit because the CAM audit market has an obvious failure mode: the only tool available to most tenants is a contingency-fee auditor who charges 33% of whatever they find. After testing reconciliation samples from published audit cases through CAMAudit, the pattern became clear: the math errors are predictable, the detection rules are definable, and the dispute process follows a repeatable structure. All of that can be automated.
The goal is straightforward: give any commercial tenant, regardless of portfolio size, access to the same forensic tools that a $500/hr auditor uses.
