Manual spreadsheet review requires you to build the model, pull lease terms into it, and apply the right formula for each of the 14 checks. An automated audit applies all 14 checks simultaneously using your lease as the input. The spreadsheet approach works for tenants with technical skills and time; the automated approach works for everyone in under 15 minutes.
TL;DR
A spreadsheet you build yourself gives you full visibility but requires 10 to 40 hours to set up correctly for a new lease; CAMAudit takes 15 minutes to upload and run all 14 checks.
Who this is for
Tenants who have been reviewing CAM reconciliations manually in a spreadsheet and want to compare the coverage, accuracy, and time investment of the manual approach versus an automated tool.
Who this is not for
Tenants with highly custom lease provisions who need to build bespoke audit logic not covered by the 12 standard detection rules.
Pro-Rata Share Error
Most commonly modeled in spreadsheets but frequently built with incorrect denominator logic.
Management Fee Overcharge
Simple percentage check that is easy to build wrong in a spreadsheet.
Gross-Up Violation
Requires occupancy data that spreadsheets rarely incorporate automatically.
CAM Cap Violation
Multi-year calculation that is error-prone in manual models.
Common Area Misclassification
Classification check that spreadsheets cannot perform without manual review of every line item.

Next Best Step
Scenario pages should bridge from diagnosis into the dispute path and audit proof.
Use the audit process if you still need to validate the billing error.
Use the dispute playbook if the issue is already active.
Run the free audit once you are ready to quantify the overcharge.
