I have watched real estate teams at 60-location restaurant groups try to audit their own CAM charges. They get through eight locations, the VP of Real Estate gets pulled into a new-store opening, and the spreadsheet dies in a SharePoint folder. Two years later the same team realizes they paid roughly the same overcharge across the same eleven landlords for two reconciliation cycles, and the recoverable window is closing fast.
I built CAMAudit because that pattern is fixable, but only if the detection step stops being a per-location spreadsheet exercise. A multi-location lease audit is a portfolio operation, not a sequence of one-off audits. This playbook is how partners run it for operators with 10 to 500 units without burning out the real estate team or the audit shop.
What a multi-location lease audit actually is
A multi-location lease audit is one engagement that covers every leased unit in a tenant's portfolio at once. The deliverable is not a stack of 60 individual audit reports — it is a ranked list of findings across the portfolio, grouped by landlord and by overcharge type, with the dispute packets pre-staged.
The reason this format matters: most multi-unit operators have a power-law distribution of overcharges. Three or four landlords account for the bulk of the dollars. If you audit one location at a time, you cannot see the pattern. If you audit the portfolio at once, the pattern is the first thing you see. That is what makes the engagement fast and what makes the partner economics work.
A typical scope covers the last two reconciliation cycles, the current year's estimated charges, and a forward-looking review of any leases up for renewal or expansion in the next 24 months. The forward-looking piece is where the highest-leverage findings tend to appear — a bad CAM cap clause caught at renewal is worth ten times the same clause caught mid-term.

How partners actually do the work
The mechanics are not glamorous. The first three days of the engagement are document collection. You are asking the operator's real estate team or AP team for the lease (executed, with all amendments), the most recent two reconciliation statements, and the current year's estimated CAM/tax/insurance pass-through schedule. For a 50-location portfolio across 18 landlords, that is 50 leases and 100 reconciliations.
The work that used to kill these engagements is the math. A trained CRE auditor running a pro-rata share check, a CAM cap test, and a gross-up reconciliation by hand is good for maybe four locations a day. At that rate a 50-location portfolio is two months of one analyst's time before you have written a single dispute letter.
The rewrite of that workflow is parallelization. Load every reconciliation into CAMAudit, run the detection rules concurrently per document, and let the system produce a portfolio-level findings table. The partner's job shifts from "do the math" to "review the findings, sort by dollar size, identify the patterns, and write the disputes." A two-month engagement becomes a two-week engagement. That compression is what lets a boutique audit shop run 10–15 simultaneous portfolio engagements instead of 3–4.
After the detection pass, the work is human again. You schedule a working session with the operator's real estate director, walk through the top 20 findings, decide which ones to dispute hard and which ones to use as renewal leverage, and group disputes by landlord so a single packet covers every store one landlord owns. That last step is what makes the business case for the engagement close — operators love that they only have to manage 18 landlord conversations instead of 50 store-level conversations.
What it costs and what it pays
Pricing across the multi-location audit market clusters into three buckets: flat-fee per location, contingency on recoveries, and hybrid (small flat fee plus contingency on findings above a threshold).
Flat-fee runs $500 to $2,500 per location depending on lease complexity, reconciliation document quality, and how much the partner has to chase missing schedules. A clean portfolio of similar shopping center leases is on the low end. A mixed portfolio of office, industrial, and ground leases with non-standard reconciliation formats is on the high end.
Contingency runs 25 to 40% of recoveries. The math works for the partner when the operator's portfolio has at least 30 locations and at least one landlord with a known sloppy reconciliation pattern. On smaller portfolios, contingency is a coin flip — you do the work and may not clear your hourly rate. The pricing model decision is the most important commercial decision in the engagement.
Hybrid is what I see most often on portfolios above 100 locations. A small flat fee covers the document load and the detection pass; contingency kicks in on findings above $5,000 per location. That structure aligns the partner with the operator on the high-leverage findings and protects the partner from doing 200 hours of work to find $400 in nuisance overcharges.
On the recovery side, ICSC and IREM data supports a 1–3% recovery band on annual occupancy cost for retail portfolios. A 50-location restaurant group paying $200,000 annual occupancy cost per location ($10M total) lands in a $100K–$300K recovery range across the engagement. The contingency partner makes $25K–$120K. The flat-fee partner clears $25K–$125K. The economics are similar; the risk profiles are not.
Where CAMAudit fits
CAMAudit is the detection layer. The 14 rules in the engine handle the math-heavy overcharge categories — pro-rata share, gross-up, CAM cap, base year errors, controllable expense caps, true-up reconciliation — and the LLM-classification rules handle the gray areas like landlord overhead pass-through and excluded service charges. Partners point the platform at the documents and get a findings table that already has the lease clause cite, the math, and the dispute language drafted.
The platform does not replace the partner. It replaces the spreadsheet. Partners still run the client conversations, the lease interpretation calls, the negotiation with the landlord's controller, and the relationship work that determines whether disputes settle or escalate. The detection step is the part where the leverage shows up.
For partners running this as a service line, the white-label program puts the platform under the partner's brand. The findings PDF, the dispute letter draft, and the audit memo all carry the partner's logo. Operators see one vendor — the partner — and the platform is invisible. For partners who want a referral relationship instead, the revenue-sharing program pays out on accounts that close through the partner's introduction without requiring the partner to do the engagement work themselves.
Frequently Asked Questions
What is a multi-location lease audit?
A multi-location lease audit is a portfolio-wide review of CAM, tax, and insurance reconciliations across every unit a tenant operates. Instead of auditing one statement at a time, you audit the full portfolio in one pass and rank findings by recovery dollars. The point is not to chase every $400 finding — the point is to find the $40,000 ones quickly.
How do partners actually run a multi-location lease audit?
Partners pull the last two reconciliation cycles and the lease abstract for every unit, load them into CAMAudit, and let the 14 detection rules run in parallel per location. Then they triage findings by dollar size, group by landlord, and prep a single dispute packet per landlord rather than one per store. That last step is what cuts the engagement from months to weeks.
What does a multi-location lease audit cost or pay?
Operators usually pay either flat-fee per location ($500–$2,500 depending on document quality) or contingency on recoveries (25–40%). On a 50-location retail portfolio, recoveries of 1–3% of annual occupancy cost are the realistic band that public ICSC and IREM data supports. The fee model you pick determines whether you make money on small-recovery portfolios or only on large ones.
Where does CAMAudit fit into a multi-location lease audit?
CAMAudit is the detection engine. It ingests the reconciliations, runs the 14 rules per location in parallel, and surfaces the findings with the lease clause and the math attached. Partners do the client interviews, the lease nuance, the dispute negotiation, and the relationship work. The platform takes the spreadsheet labor off the table so partners can scale past the 10–15 simultaneous engagements that kill most boutique audit shops.
Run the playbook on your next portfolio
If you are a real estate or AP leader at a multi-unit operator, the question to take to your CFO this quarter is whether you have ever run a portfolio-level audit, not a per-store one. If you are a partner thinking about adding lease audit as a service line, the multi-location engagement is the one that scales — single-store audits do not. Either way, the free scan on a single reconciliation will tell you in under fifteen minutes whether the recovery dollars are real before you commit to a full portfolio engagement.
