NNN reconciliation for taxes, insurance and CAM
Triple-net leases pass three cost pools through to tenants. CamProof reconciles each pool separately — with its own admin fee, base year or cap — and totals them on one statement.
How it works
- Put each expense account in a pool: CAM, Real estate taxes or Insurance (add others, e.g. Utilities).
- Set the lease terms per pool — many leases cap CAM but not taxes, or charge an admin fee on CAM only.
- Send one statement per tenant with each pool's true-up and the new monthly NNN estimate.
Why CamProof
For owners, bookkeepers and small property managers who reconcile CAM, taxes and insurance once a year — and would rather not rebuild the spreadsheet every time.
Starts from your books
Drop a QuickBooks Profit and Loss or transaction detail, or a Yardi, AppFolio or Buildium export. Map each account to a pool once; CamProof remembers it next year.

FAQ
What is an NNN reconciliation?
Under a triple-net lease the tenant pays its share of property taxes, insurance and common area maintenance, usually as monthly estimates. After year-end the landlord compares actual costs with the estimates and bills the shortfall or credits the overpayment.
Are taxes and insurance usually capped?
Usually not — caps in most leases apply to controllable CAM expenses, while taxes, insurance, utilities and snow removal are treated as uncontrollable. CamProof defaults the taxes and insurance pools to uncontrollable and lets you change any account.
Is my data uploaded?
No. Your ledger, tenants and lease terms are read and calculated by JavaScript running in your browser tab, and saved only in this browser (or in a project file you download). There's no account and no server copy.
What is a CAM reconciliation?
After the year ends, the landlord compares each tenant's actual share of common area maintenance (and, in NNN leases, taxes and insurance) with the monthly estimates the tenant paid, then bills the shortfall or credits the overpayment.
Which accounting exports work?
QuickBooks Online and Desktop Profit and Loss, General Ledger and Transaction Detail by Account reports, plus Yardi, AppFolio, Buildium, Rent Manager or any CSV/Excel file with account and amount columns. You can also type expenses in.
Does it replace reading the lease?
No. CamProof applies the terms you enter — shares, base years, stops, caps, gross-ups and fees — in the order most leases use. Your lease governs; review each statement before you send it.
What's free?
