The percentage rent bill has a sales number. You have your own total. You hover a finger over the line item on your commercial lease addendum, where percentage rent terms are spelled out, and tap the edge of the paper twice as you do the quick math in your head. The discrepancy between the two numbers is big enough to change your quarterly operating budget by a meaningful margin, so you do not just sign off on the bill as-is. You pull a pen out of your mug to cross-reference the figure against the terms you agreed to when you signed the lease.
Gross sales definition as written in your lease
You start with the exact definition of gross sales laid out in your lease document, because every landlord uses slightly different parameters for this figure. Some definitions count every dollar that comes through your point of sale system, including store credit redemptions and shipping fees for orders picked up at your location, while others narrow the scope to only in-person, non-discounted transactions. You flip to the percentage rent addendum of your lease and highlight every clause that contributes to the gross sales definition, so you do not miss any line items that count toward the total the bill should use. Even small changes to this definition, like including or excluding loyalty program discounts, can shift the billable total by hundreds or thousands of dollars, so you make sure every relevant clause is marked for reference.

Excluded transaction categories your lease outlines
Almost all percentage rent leases include explicit categories of sales that do not count toward the billable total, and these exclusions are the most common source of discrepancy between your number and the number on the bill you received. Typical exclusions include sales tax you collect and remit to state revenue departments, returns and refunds issued during the reporting period, and wholesale sales you make to other businesses for resale. Some leases also exclude proceeds from insurance claims, store credit purchases (only redemptions count in those cases), and donations you make to local nonprofits. You cross off every transaction category on your sales report that matches these exclusions to get an accurate preliminary total, and note each exclusion next to the corresponding line in your lease for easy reference later.
Reporting timelines that impact final sales calculations
Landlords often use calendar quarters for percentage rent reporting, while your internal sales tracking may follow fiscal quarters that align with your business’s accounting cycle. This misalignment means you might be comparing sales from a 12-week period to a bill that uses a 13-week period, or vice versa, if one quarter includes an extra week for your internal reporting. You also check for language that specifies when sales are counted: some leases count sales on the date the transaction is processed, while others count them on the date payment is received, which can shift thousands of dollars in sales from one reporting period to the next if you process a high volume of net-30 invoices for business clients. Illustrative example: If your lease counts sales on payment receipt date, $12,800 in invoices you processed on March 30 that were paid on April 2 count toward your Q2 total, not your Q1 total, which would lower your Q1 percentage rent bill by that amount multiplied by your agreed percentage rate.
Common landlord calculation errors to cross-reference
Landlords often manage dozens of commercial properties at once, so their administrative teams make small, accidental errors that add up to big discrepancies in percentage rent bills. The most frequent error is using the wrong percentage rate for your reporting tier: many percentage rent leases have a breakpoint, where you only pay percentage rent on sales above that breakpoint, or tiered rates that increase as your sales exceed certain thresholds. Other errors include failing to subtract the breakpoint amount from your total sales before applying the percentage rate, or including sales from a temporary pop-up you ran in another part of the building that your lease explicitly excludes from percentage rent calculations. You cross-check the rate listed on the bill against the rate in your lease, and confirm the breakpoint is applied correctly before you move to reconciliation. Even a 0.5% rate error can add up to thousands of dollars in overcharges for high-volume businesses, so you verify that number twice before moving forward.
Adjustment steps to reconcile conflicting sales figures
Once you confirm the source of the discrepancy between your sales total and the total on the bill, you follow a clear process to align with your landlord on the correct amount owed:
- Compile a line-item breakdown of your total sales for the reporting period, with excluded categories separated out and labeled clearly to match the terms in your lease. Include copies of point of sale reports, accounting ledgers, and refund logs to back up every adjustment you make.
- Calculate the adjusted gross sales total by subtracting all applicable excluded categories from your total sales, then apply the breakpoint and percentage rate from your lease to get the amount you owe.
- Draft a short, friendly note to your landlord’s property management team that lists each discrepancy, cites the exact clause in your lease that supports your adjustment, and includes the supporting documentation for your adjusted total.
- Send the note and supporting materials to the property management team at least 10 business days before the percentage rent bill is due, so they have time to review your submission and adjust the bill before your payment is processed.
- Follow up with the team 3 business days before the due date if you have not received a confirmation that your adjustment is approved, to avoid late fees for underpayment.
If the property management team pushes back on any of your adjustments, you can share additional context for the excluded transactions, and reference the agreed lease terms to align on a correct total. You can also pull in your accounting lead to walk through the sales tracking process if the team needs additional clarity on how you arrived at your number. If you need a centralized place to store your lease clauses and supporting sales documents for this review, Lease Jacket organizes those materials so you can pull them up in seconds during these conversations.
When you return to this lease page during your next quarterly review
You flag this page of your lease with a sticky note now, so you can reference it immediately as soon as you receive your next percentage rent bill, instead of hunting through the full lease document to find the relevant clauses. You jot down notes in the margin next to the gross sales definition, exclusions, and breakpoint terms to remind yourself of the adjustments you made this quarter, so you do not have to redo that research for the next reporting period. You also add a reminder to your calendar three days before the end of each quarter to pull a preliminary sales report, apply the exclusions and breakpoint, and have your adjusted total ready before the bill arrives, so you can resolve any discrepancies before the due date. This proactive step cuts down on the time you spend reviewing percentage rent bills each quarter, and prevents you from overpaying for charges that do not align with the terms you agreed to when you signed your lease. You can also use the margin notes to track any changes to the lease terms you agree to with your landlord during renewal negotiations, so you always have the most up-to-date calculation parameters on hand when you review future bills. Over time, this consistent process builds trust with your property management team, so they are more likely to approve your adjusted totals quickly without extra back and forth.
