Add CAM audit to your accounting practice
Your firm already touches every dollar of a client's rent and occupancy cost. The monthly AP cycle posts the rent invoice, the CAM estimate, and the property tax escrow. The annual close picks up the year-end reconciliation true-up. A true-up is the year-end settle-up against the estimates. What most firms skip is one check. Does the CAM reconciliation match what the lease allows? That gap is why I built CAMAudit. Add a CAM review to your current work. It turns a quiet expense posting into a deliverable that finds real money for the client.
Outsourced accounting (CAS engagement): Client Accounting Services, the AICPA term for the bundled outsourced accounting work that includes monthly close, AR/AP, payroll oversight, financial reporting, and increasingly advisory services. CAS engagements are typically billed as fixed monthly retainers, with annual deliverables layered on for tax, planning, and compliance reviews. CAM reconciliation review is a natural annual deliverable to add for clients with commercial leases because the source documents already pass through the firm's monthly workflow.
Where CAM review fits in the existing workflow
Your workflow already makes three things that feed a CAM review.
The first is the lease abstract. When a client signs a new lease, your firm updates the rent schedule. You log the base rent, the CAM estimate, the rent steps, and the pro rata share. Pro rata share is the tenant's slice of building costs. That abstract anchors the review. The dispute turns on what the lease says about each charge, not on what the landlord billed.
The second is the monthly AP postings. Every CAM estimate the landlord bills runs through AP. The running monthly estimate becomes the check against the year-end true-up. A firm with a clean close already has the data to test the reconciliation math.
The third is the yearly reconciliation statement. The landlord sends it in Q1 or Q2 for the prior calendar year. This is the document that starts the CAM review. Without a review, the firm posts the true-up and moves on. With one, the firm runs the statement through CAMAudit, checks the findings, and tells the client what to do.
The work fits your current rhythm. You already hold the source documents.
The annual CAM review deliverable
For each property the client leases, the firm makes a yearly deliverable with three parts.
The first part is the reconciliation summary. This is a one-page note. It shows what the landlord billed, the prior year estimate, and what the true-up makes the client pay or get back. This framing helps the client see why the reconciliation matters.
The second part is the findings detail. This is the report from CAMAudit. It lists each billing error, the lease clause that governs the charge, and the dollar variance. Variance is the gap between billed and allowed. A clean reconciliation keeps this part short. One with many findings makes this part the core of the work.
The third part is the recommendation. The firm tells the client what to do. The options are accept, ask for backup, dispute, or use the lease audit right. The call weighs the dollar size, the lease wording behind each finding, and the dispute deadlines. After testing reconciliation samples from published audit cases through CAMAudit, the most common call is to ask for backup. That applies to findings above a dollar line the firm sets with the client.
"The outsourced accounting firm already has the data. They already touch the rent ledger, the CAM estimates, and the reconciliation statement. What they don't have is a way to systematically check whether the landlord billed what the lease permits. I built CAMAudit so the firm can add that check without becoming CRE specialists." - Angel Campa, Founder, CAMAudit
Engagement structures for outsourced firms
Firms set up CAM review in one of three ways. The right one depends on the current engagement.
The first way bundles it into the CAS retainer. For full-service CAS clients on a monthly fee, the firm adds CAM review inside the current scope. The client pays the same retainer. The firm eats the extra cost. In return it gets a stickier engagement and a stronger advisory role.
The second way is a yearly add-on fee. For bookkeeping-only or AP-only clients, the firm scopes CAM review as its own project. The price runs $750 to $1,500 per property. It depends on lease complexity and the years under review. The first year often covers a multi-year lookback, which lands at the high end.
The third way is a recovery share. A few firms run CAM review on contingency for clients with many properties. The firm takes a percent of the money recovered. This works only when the firm trusts the detection method. Its pay depends on findings that turn into real recovery.
Capacity planning
Capacity planning is simple here. The work is yearly and seasonal. Most reconciliations arrive in Q1 or Q2. A firm with 25 properties spends 12 to 25 hours in that window. Most firms absorb that without new hires.
The work fits an experienced accountant. It does not need a lease auditor's deep CRE knowledge. CAMAudit handles the detection. The accountant reads the lease excerpt, reviews the finding, and checks that the citation matches the bill. Any accountant who reads contracts can do this.
Quality control and second-review
If CAM review is new for your firm, add a second review in the first season. Here is how it works.
The first accountant builds the deliverable from CAMAudit's findings. A senior accountant checks two things. Does the lease wording back each finding? Does the recommendation fit the dollar size and the dispute deadline? The senior signs off before the work goes to the client.
After the first season, you can relax the second review for simple reconciliations. Keep senior review for multi-year reviews and high-dollar findings.
Client communication and the recommendation conversation
The work lands best in a live talk, not a cold email. The talk has three parts.
First, present the reconciliation summary and frame the dollars. Say a client pays $50,000 in yearly CAM. A $3,000 finding is a 6% recovery. That framing shows the client why it matters.
Second, walk through the top findings. Point to the lease clause behind each one. The client does not need to learn the CAM detection rules. The client needs the two or three findings that drive the call.
Third, give the recommendation and the next steps. For findings worth pursuing, the next step is a correction draft or a request for backup. For findings to watch, the next step is to update the lease abstract for next year.
How the white-label program supports the engagement
The CAMAudit white-label partner program lets firms offer CAM review under their own brand. It gives you the detection engine, branded findings reports for your clients, and partner-portal access for your staff.
If your firm has 15 to 50 commercial tenant clients, model the platform cost against your fees. Weigh the time you save, the client fee, the yearly audit volume, and the retention from a deliverable your rivals lack.
Building the practice over multiple seasons
CAM review is a build across several seasons. The first season sets the workflow. You learn which clients have the most CAM risk. You build a playbook for the disputes that findings create. The second season sharpens the deliverable. You roll it out to more tenant clients. By the third season, the practice adds real revenue. It also sets your CAS work apart.
If you start now, the upfront cost is small. You spend time to wire CAMAudit into your workflow and run one or two pilot reviews. After that, every new reconciliation runs the same workflow and makes the same deliverable.
Frequently Asked Questions
Where does CAM reconciliation review fit in an outsourced accounting workflow?
CAM reconciliation review fits into the annual rent and occupancy cost review that most outsourced accounting firms already run for commercial tenant clients. The reconciliation statement arrives once per year, typically in Q1 or Q2 covering the prior calendar year, and it represents the largest single occupancy variance the client will see all year. Adding a structured CAM review on top of the routine rent posting work converts a passive AP entry into a deliverable the client can use to recover overcharges.
How long does CAM review add to a monthly client engagement?
CAM review is an annual deliverable, not a monthly one. The reconciliation statement arrives once per year per property. With CAMAudit handling the detection layer, the practitioner time required is approximately 30 to 60 minutes per property per year for review, client communication, and recommendation writeup.
Does the firm need a CRE specialist on staff to add CAM review?
No. CAMAudit applies the CAM compliance checks systematically and produces a findings report with lease citations and dollar variances. The accounting practitioner reviews the output, validates the findings against the lease, and presents the recommendation to the client. The CRE-specific knowledge is encoded in the detection logic.
What does the deliverable look like to the client?
The client receives a written summary of the CAM reconciliation review, the findings report from CAMAudit with each billing discrepancy and dollar variance, and a recommendation on whether to dispute, request supporting documentation, or accept the reconciliation.
How does the firm price CAM review inside an outsourced engagement?
Most outsourced accounting firms either bundle CAM review into the existing CAS engagement fee as a value-add, or break it out as an annual fixed-fee deliverable in the $750 to $1,500 range per property. Bundling works for retainer relationships. Breaking it out works for multi-property scoping.
