Franchise operators in NNN leases routinely find themselves writing a check in March or April that they didn't fully anticipate in January. The CAM reconciliation arrives, the true-up balance is due in 30–60 days, and the cash comes from operating funds that were allocated elsewhere.
This is a cash flow problem that has a straightforward accounting solution — but only if you understand how the occupancy cost flows through your P&L.
The Margin Bridge: From Sales to Cash
A margin bridge is a simple tool that traces how gross revenue becomes available cash, one subtraction at a time. For a single franchise location:
Gross Revenue
– Cost of Goods Sold (COGS)
= Gross Profit
– Labor (including management)
– Royalties and marketing fund contributions
– Occupancy cost (base rent + NNN pass-throughs)
– Other direct operating costs (supplies, utilities, technology)
= EBITDA (before depreciation, interest, and taxes)
– CapEx / depreciation
– Interest expense (if financed)
= Net Operating Income (NOI)
A location with $1.1M in revenue, 28% COGS ($308K), 28% labor ($308K), 6% royalties/marketing ($66K), 10% occupancy ($110K), and 8% other operating costs ($88K) shows EBITDA of approximately $220K (20%) — a healthy-looking store.
But if that location also receives a $14,000 CAM true-up in April and a $3,200 insurance true-up adjustment in Q3, the actual cash drain from occupancy is $127,200 — not $110,000. The OCR was 11.6%, not 10%.
The P&L showed 20% EBITDA. The actual cash position reflects 18.7%.
Where the True-Up Disappears in the P&L
If you're on a cash-basis accounting system, the monthly CAM estimate payment hits the P&L in the month paid. The annual true-up hits the P&L in the month it's paid — which means Q1 of the following year absorbs a cost that accrued throughout the prior year.
For a single location, this is manageable. For a 10-location operator whose stores collectively generate $80,000–$120,000 in annual true-up payments, having all of that hit Q1 cash flow is a significant planning problem.
The Accrual Accounting Fix
Accrual accounting matches costs to the periods in which they're incurred, not the periods in which they're paid. For CAM true-ups, the correct accrual treatment is:
Monthly accrual entry:
Debit: CAM Expense (estimated monthly true-up accrual)
Credit: Accrued Liabilities — CAM True-Up
Each month, you accrue 1/12 of your estimated annual true-up as an additional occupancy cost. When the actual reconciliation arrives, you settle the accrual against the actual balance due.
How to estimate the monthly accrual:
The simplest approach is prior-year actuals:
Prior year true-up balance ÷ 12 = monthly accrual amount
If your prior year true-up was $9,600, accrue $800/month in the current year. If the actual true-up comes in at $10,400, you'll have an $800 catch-up adjustment in the month the reconciliation settles. That's a minor cash event, not a surprise.
More precise approach:
If you have access to the prior year's expense schedule, look at which CAM categories are growing. If property taxes increased 12% due to reassessment and insurance increased 8% due to market pricing, adjust the accrual accordingly rather than using a flat prior-year estimate.
Building the Occupancy Accrual Into Your Monthly Close
The monthly close process for a multi-unit operator should include:
Step 1: Verify the base rent payment posted correctly. This is almost always right, but lease amendments or escalation steps that weren't updated in the accounting system create errors.
Step 2: Record the estimated monthly NNN pass-through. If your estimates are $2,400/month for CAM, $800/month for taxes, and $350/month for insurance, post those as estimated payments even before writing the check to the landlord.
Step 3: Post the true-up accrual. Based on your estimate, add the monthly true-up accrual to the accrued liabilities account. This is the amount in excess of your current monthly estimates that you expect to owe at year-end.
Step 4: When the reconciliation arrives, verify before posting. Don't book the true-up balance as a payable until you've confirmed the reconciliation is accurate. The accrual you've been building provides a buffer — you have 30–60 days to verify, not 30–60 days to come up with cash.
Why Occupancy Cost Behaves Differently Than Payroll
Payroll costs are managed through scheduling and operational controls. If labor runs over target, you adjust hours the next week. The cost is both variable and responsive to management action.
Occupancy cost has a completely different control structure:
- Base rent is fixed for the lease term (except escalation steps).
- CAM, taxes, and insurance are variable but not operationally controllable — you can't decide to use less parking lot lighting.
- The only lever for occupancy cost reduction is lease negotiation, location exit, or CAM audit recovery.
This means the financial management of occupancy cost happens at lease signing, at renewal, and during the annual reconciliation audit window. There's no weekly adjustment mechanism. Operators who don't actively use the reconciliation audit window are effectively leaving their occupancy cost management entirely in the landlord's hands.
The Cash Flow Projection for a Multi-Unit Portfolio
For a 10-location portfolio, occupancy cash flow planning looks like this:
- Collect all prior year reconciliations and note the true-up balance for each location.
- Estimate current year true-up for each location based on known changes (reassessments, management fee changes, year-over-year expense trends).
- Identify the expected reconciliation receipt dates for each location (typically 90–120 days after year-end).
- Map the true-up payments to the months they'll be due.
- Check which locations have audit windows expiring in the current year — those are priority review items.
This exercise turns an annual surprise into a planned cash event. It also identifies which locations have the highest expected true-ups — and those are the locations where a CAM audit has the best ROI potential.
Use the Audit Window Actively
The true-up you verify before paying is the true-up you control. Run each reconciliation through CAMAudit before posting the balance as a payable. If the audit flags overcharges, you have time to dispute before the payment deadline.
Frequently Asked Questions
Should I put CAM, taxes, and insurance in separate P&L accounts or combine them into "occupancy cost"?
Separate accounts. Bundling NNN components into a single occupancy line makes it impossible to analyze which component is driving variance, and it makes cross-location comparison meaningless. At minimum, separate: base rent, CAM, property taxes, insurance.
What if my landlord raises the monthly estimate mid-year?
When a landlord adjusts monthly estimates (typically done annually but sometimes mid-year), update your accrual model accordingly. The revised estimate is closer to the actual expected cost, which means your monthly true-up accrual amount should be recalculated.
How do I handle a credit true-up in my accounting?
A credit (where actuals came in below estimates) reduces the accrued liability. If you've been accruing for a true-up and receive a credit instead, reverse the accrual and record the credit as a reduction in occupancy cost expense for the period in which the reconciliation settles.
Is it worth hiring an accountant to set up the accrual system?
For operators with fewer than 5 locations, a spreadsheet-based approach often works. For 10+ locations, the complexity of tracking multiple reconciliation timelines, different lease-year end dates, and varying accrual estimates across locations justifies a dedicated accounting setup. The cost of a well-built system is recovered many times over in avoided surprises and timely audit actions.
What if the landlord delivers the reconciliation late?
Deliver the reconciliation late enough and you may lose days from your audit window. Document the receipt date (email, certified mail, etc.) for every reconciliation. Your audit window typically starts from the date of receipt, not from the reconciliation date. If your lease has a deadline for landlord delivery, late delivery may also affect the landlord's ability to collect a true-up balance — check the specific provision.
Does the accrual approach work on a cash-basis tax return?
For tax purposes, cash-basis businesses deduct costs in the year paid. The accrual in your management accounts doesn't change your tax filing methodology. The practical benefit of the accrual is operational planning and P&L accuracy — it doesn't affect the timing of your tax deduction.
