What do manual spreadsheet audits typically miss?

Spreadsheet models are excellent at math-based checks (pro-rata, management fee percentage) but struggle with classification-based violations. They cannot reliably identify whether a line item description represents an excluded capital expense or a legitimate operating cost. CAMAudit applies a trained classification model to every line item, which is the category of error most frequently missed by manual review.

Is there any reason to keep using a spreadsheet alongside CAMAudit?

Yes, for tenants who want to track CAM trends across multiple years or multiple properties in a custom format. CAMAudit generates findings reports per reconciliation; a spreadsheet can aggregate findings across your entire portfolio for executive reporting or lease renewal negotiation. The two tools are complementary for large portfolio users.

Comparing Options

Automated CAM audit vs. manual spreadsheet review

Manual spreadsheet review requires you to build the model, pull lease terms into it, and apply the right formula for each of the 13 checks. An automated audit applies all 13 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 5 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 5 minutes to upload and run all 13 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.

What CAMAudit Checks in This Scenario

Rule 4

Pro-Rata Share Error

Most commonly modeled in spreadsheets but frequently built with incorrect denominator logic.

Rule 3

Management Fee Overcharge

Simple percentage check that is easy to build wrong in a spreadsheet.

Rule 5

Gross-Up Violation

Requires occupancy data that spreadsheets rarely incorporate automatically.

Rule 6

CAM Cap Violation

Multi-year calculation that is error-prone in manual models.

Rule 12

Common Area Misclassification

Classification check that spreadsheets cannot perform without manual review of every line item.

What to Do Next

1List the 13 CAM detection rules and assess how many your current spreadsheet covers versus how many it misses.
2Estimate the hours you spend per reconciliation cycle building and maintaining your spreadsheet model.
3Run a parallel test: audit the same reconciliation with your spreadsheet and with CAMAudit and compare the results.
4Note any violations CAMAudit found that your spreadsheet missed, particularly classification-based rules.
5Calculate the time-cost of manual spreadsheet review versus the $199 flat fee for an automated audit.
6Decide whether to replace, supplement, or retire the spreadsheet approach based on the comparison.
