Turn a confusing reconciliation into a reviewable case.
Upload your two files or use the professional example. There is no account, payment, or hidden checkout.
Fastest path
Start with the lease and the statement.
CloseDelta reads both files in this browser, extracts lease rules and statement charges, then fills the detailed review below. The files are not uploaded or stored.
Local document processing
Primary review
Audit every charge against the lease.
Enter the amount charged to your location, choose the treatment stated in the lease, and cite the clause. CloseDelta separates likely exclusions from charges that only need support.
Secondary check
Rebuild the portfolio-level math.
Use the totals below to screen the expense cap, administration fee, and remaining statement balance.
Step 1
Statement totals
This model is an informational screening tool, not legal, accounting, or lease-audit advice.
The complete workflow
From lease language to a defensible question list.
Rebuild the math
Compare billed amounts with the calculation allowed by the lease and prior-year baseline.
Collect support
Turn each flag into a focused request for invoices, ledgers, allocation schedules, or explanations.
Escalate with evidence
Hand a structured packet to your team, accountant, attorney, or professional lease auditor.
Designed for operators
One missed clause can repeat across every location.
Validated on a professional example
$37,130 flagged across seven reviewed charges.
CloseDelta reproduced the line-by-line treatment in a published professional CAM training example: six excluded categories and one allowed fixed administration fee. It also surfaced the 30-day notice problem instead of hiding it behind the dollar total.
