CAM reconciliation from QuickBooks

Export the year from QuickBooks Online or Desktop, drop the file, and map each expense account once. No QuickBooks connection, no upload — the file is read in your browser.

🔒 Ledger & leases never leave your browser📒 QuickBooks · Yardi · AppFolio · Excel🧾 Statements that show the math🆓 Free, no signup

How it works

  1. In QuickBooks, run Profit and Loss or Transaction Detail by Account for the reconciliation year (filter to the property's class or location if you use them) and export to Excel.
  2. Drop the file — CamProof reads the account sections and totals and skips subtotal rows.
  3. Map accounts to CAM, taxes, insurance or Exclude. Mortgage interest, depreciation, commissions and capital items are excluded by default.

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.

Real lease mechanics

Pro-rata by GLA, occupied area or fixed %, partial years by day, gross-up of variable costs, base years, expense stops, three kinds of caps, admin fees inside or outside the cap.

Statements tenants accept

One page per tenant with every step of the calculation, the building's expense detail, the balance or credit and the new monthly estimate. Print or save as PDF.

Catches mistakes first

Warnings for missing GLA, tenant areas larger than the building, shares over 100%, credits from reversed signs, caps without a basis and leases outside the period.

Landlord summary

See where every dollar went: billed, absorbed by vacancy, lost to base years and caps, and earned in admin fees — your recovery rate per pool.

Private by design

Rent rolls and ledgers are processed in your browser tab. No account, no upload, no connection to your accounting system. Save the project as a file you keep.

FAQ

Which QuickBooks reports work?

Profit and Loss (summary or by month — the Total column is used), Transaction Detail by Account, General Ledger and Journal reports exported to Excel or CSV. Yardi, AppFolio, Buildium, Rent Manager and Excel files with account and amount columns work too.

Does CamProof connect to my QuickBooks?

No. You export a report and drop it in. Nothing is uploaded and no QuickBooks permission is ever requested.

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?
