A credit memo is stapled underneath. The invoice total ignores it. You tap the edge of the commercial lease addendum you’re reviewing, where this attached invoice is listed as a required pass-through charge for quarterly common area maintenance. You squint at the fine print of the credit memo, which is dated two weeks before the invoice was issued, for overpaid utilities from the prior quarter. You reach for your pen before you do anything else, already mapping where this discrepancy fits into your lease reconciliation workflow.
What the paper says
The top of the invoice lists your business’s legal name, your suite number, and the quarter for which common area maintenance (CAM) fees are being charged, broken out into line items for landscaping, parking lot repairs, security patrols, and shared utility costs. The total listed is $4,122, marked due in 15 days, with a late fee of 1.5% per month applied to any unpaid balance after the due date. The credit memo tucked underneath is on your landlord’s official letterhead, notes a miscalculation in the prior quarter’s utility allocation that left your business overpaying for shared water and electric costs, and explicitly states the credit should be applied to your next CAM invoice. The credit has no listed expiration date, and there is a signature from your property manager at the bottom, dated 12 days before the invoice was generated. There are no notes on the invoice referencing the credit, and the line item for utilities is listed at the full unadjusted amount, with no indication that a prior overpayment is being offset. Illustrative example: The credit memo is for $1,287, an amount equal to 31% of the total listed invoice value.
What you leave alone
You do not adjust the printed numbers on the invoice itself, even if the total is clearly incorrect, because any handwritten changes can create confusion when you share the document with your accounting team or follow up with the property management team. You leave the staple intact, so the credit memo stays directly attached to the invoice it applies to, so no one reviewing the document later misses the offsetting credit. You also leave any pre-printed payment coupons or remittance slips attached to the back of the invoice for now, so you can cross-reference the invoice number when you submit your adjusted payment. You avoid marking up the credit memo itself, so the signature and explicit terms of the credit remain fully legible for future reference. You also avoid crossing out any line items on the invoice, even the utility line that is overstated, because unapproved markups can be interpreted as a dispute of the full invoice if the document is ever reviewed during a lease audit.
The ten-minute check
You run through this quick, structured check to confirm you have all the context you need to resolve the discrepancy before you take any further action:
- First, cross-reference the credit memo’s stated reason for the credit with your prior quarter’s CAM payment records, to confirm the overpayment the memo references matches the amount you paid three months prior for shared utilities.
- Second, verify that the legal name and suite number listed on the credit memo match the information on the invoice and your signed lease agreement, to rule out the possibility the credit was issued to a different tenant in the building by mistake.
- Third, compare the date of the credit memo to the issue date of the invoice, to confirm the credit was issued before the invoice was generated, so you have proof the charge adjustment should have been applied before the invoice was sent to you.
- Fourth, note the exact credit amount in the margin of the separate lease reconciliation sheet you keep for your tenancy, using the same invoice number listed on the front of the document for easy tracking later.
- Fifth, calculate the adjusted total you owe by subtracting the credit amount from the listed invoice total, and write that adjusted amount on a sticky note you place on the front of the invoice, so you do not accidentally pay the full incorrect amount when you process bills at the end of the week.
Where the page goes
After you finish the ten-minute check, you place the invoice and attached credit memo in the designated slot of your lease document folder, right next to the signed copy of your CAM addendum that outlines the process for billing adjustments and credit applications. You send a quick, scanned copy of both documents to your accounting lead, with a short note noting the adjusted payment amount and the date you plan to follow up with the property manager to confirm the credit will be applied to your account. You keep the original hard copy in your folder rather than sending it in with your payment, so you have a fully executed version of the credit memo on hand if there is any delay in the credit being posted to your tenant ledger. If you use a digital lease tracking tool, you upload the scanned copy to the specific invoice entry for this quarter’s CAM fees, tagging the document so it appears when you search for either the invoice number or the credit memo number. You can log this discrepancy and attach the scanned documents directly to your lease record in Lease Jacket if you want to set an automated reminder to follow up on the credit posting in 7 days.
What you do not assume
You do not assume the property management team has already applied the credit to your account, even though the memo explicitly states it should be applied to this specific quarter’s invoice, because administrative oversights are common in large property management portfolios. You do not assume the credit will roll over to future invoices if you pay the full listed amount now, as unapplied credits can get lost during portfolio transitions or software updates for property management teams. You do not assume the person processing your payment will see the credit memo if you send it in with your check, so you include a short, clear note with your payment that lists the invoice number, the credit memo number, the total invoice amount, the credit amount, and the adjusted amount you are paying. You also do not assume the discrepancy is an intentional overcharge, so you frame all your follow up communication as a request for confirmation rather than a demand, which keeps your relationship with the property team collaborative. You avoid assuming that the credit will apply to other charges like rent or late fees, unless explicitly stated, so you only apply it to the CAM invoice it is designated for to avoid accounting mismatches.
The next time you open it
You pull this document out again 7 days after you submit your adjusted payment, to cross-reference the amount posted to your tenant ledger with the adjusted total you calculated. You first check if the full credit amount is listed as an applied credit next to the invoice number on your ledger, and if the remaining balance for the invoice is marked as paid in full. If the credit is posted correctly, you add a small note to the bottom of the sticky note on the front of the invoice noting the date the credit was applied, and file the document in your permanent tenancy records for tax and lease reconciliation purposes. If the credit is not posted correctly, you use the contact information listed on the credit memo to reach out to the property manager, share the scanned copy of both documents, and request the credit be applied to your account within 3 business days. You also pull this document out at the end of the year when you do your annual lease reconciliation, to confirm the credit is reflected in your total CAM payments for the year and matches the amount listed on the annual CAM reconciliation statement your landlord provides. If you ever renegotiate your lease terms at the end of your initial term, you can reference this document as an example of billing discrepancies that you want to add explicit pre-approval steps for in your next lease agreement, to reduce the chance of similar oversights in the future.
