Membership cohort verification
Pull cohort-level membership retention data; do not accept aggregate counts
Why:Aggregate membership count without cohort segmentation is the leading earnings-quality misrepresentation in express tunnel deals. Promotional-priced cohorts ($9.99–$14.99 introductory) show 30–50% higher churn than standard-rate cohorts; a site at 4,200 members with 45% promo-acquired has materially different forward revenue than the headline implies.
Check:Monthly cohort retention table for trailing 24 months · acquisition-pricing tag per cohort · ARPM by cohort · CRM/POS export with member start dates and churn timestamps
critical
Earnings Quality
Reconcile membership ARPM against bank deposit categorization
Why:Average revenue per member per month (ARPM) is the durability proxy for the recurring revenue layer. ARPM below $20 indicates heavy promotional-rate mix; above $30 indicates premium-positioned book. Bank deposit reconciliation catches inflated reported ARPM.
Check:Trailing 12-month bank deposits by category · ACH/recurring billing exports · variance between presented ARPM and deposit-derived ARPM · refunds/chargebacks
high
Earnings Quality
Build deferred-revenue schedule for prepaid memberships
Why:Annual-prepaid membership creates a deferred-revenue liability that must transfer to new entity. Cash-basis books often misstate this and overstate trailing EBITDA.
Check:Membership billing terms (annual vs. monthly) · cash collected by month · earned vs. unearned schedule · purchase-price-allocation memo · accounting basis (cash vs. accrual)

Test membership conversion funnel + first-wash promotional cost
Why:Customer acquisition cost (CAC) for membership conversion is the unit-economic input that determines forward LTV. CAC above $30 with promotional pricing models rarely achieves positive LTV.
Check:First-wash promotional offer cost (free / $1 / discounted first month) · conversion rate (first-time → member) · standard-rate membership LTV vs. promotional-rate LTV · payback period

Environmental + Phase I
Order Phase I environmental site assessment pre-LOI (now SBA-categorical)
Why:Phase I environmental assessments are categorically required by SBA lenders on car wash transactions as of Q1 2026. PFAS contamination, hydrocarbon residue from fluid leakage, and UST risk from historical solvent storage are the three primary triggers. Discovery at commitment stage kills closings; pre-LOI Phase I is now table stakes.
Check:Current Phase I ESA report (within 12 months) · PFAS sample analysis · UST history and removal documentation · spill/release history · prior site uses (gas station / repair shop / industrial)
critical
Fundability
Confirm OSHA HazCom + chemical SDS inventory
Why:OSHA Hazard Communication Standard requires complete Safety Data Sheets for all onsite chemicals (surfactants, polymers, drying agents) plus staff training records and hazard signage. Gap is a finding at lender Phase I review.
Check:Current SDS binder for all chemicals onsite · staff HazCom training records · hazard signage at storage areas · spill kit + first-aid documentation

Site value vs. operating value
Separate site real-estate value from operating-business EBITDA multiple
Why:Express tunnel sites on owned real estate in high-traffic corridors carry embedded land value uncorrelated with EBITDA. Buyers applying a single EBITDA multiple to total consideration without separating real estate are systematically overpaying for the operating business. Q1 2026: 34% of deals reviewed surfaced this confusion.
Check:Independent real estate appraisal · cap rate for the corridor (separate from operating business) · ground lease alternative valuation · build-to-suit replacement cost · NOI of the real-estate component vs. operating EBITDA

Chemical + utility normalization
Normalize chemical and utility costs at current run-rate
Why:Chemical pricing (surfactants, polymers, drying agents) and utility costs (water, electricity) bottomed in 2024 and reverted upward through 2025–2026. Trailing-period EBITDA capturing 2024 trough costs overstates steady-state earnings 8–14 percentage points; 22% of Q1 deals carried this distortion.

Category 05 · 3 items
NPDES + state water reclamation
Verify NPDES stormwater permit + SWPPP currency
Why:NPDES permit coverage is mandatory for industrial stormwater discharge; gap means strict-liability exposure and SBA financing risk. Stormwater Pollution Prevention Plan (SWPPP) must be current; permit conditions include monitoring and recordkeeping that audit checks.
Check:State NPDES permit (active, current) · Stormwater Pollution Prevention Plan (last update) · monitoring records · municipal MS4 compliance · prior NOVs or enforcement actions
high
Fundability
Audit reclaim system performance against state-specific requirements
Why:State water reclamation requirements vary widely (CA mandates 80% on new builds, retrofit by 2027; CO mandates on new construction; NY DEC SPDES requires in NYC metro). Non-compliant sites face permit renewal risk. Reclaim performance also drives utility-cost economics.
Check:Reclaim percentage actual vs. required · system manufacturer + age · maintenance/cleaning logs · municipal water meter vs. discharge meter delta · upcoming retrofit deadlines (e.g., CA 2027)
high
Transferability
Test reclaim system actual reclamation rate vs. permit requirement
Why:Reclaim performance varies materially by system age and maintenance state. A site claiming 80% reclaim under a Title 22 mandate but actually running 40% reclaim is non-compliant; permit renewal denial follows. Maintenance lapses degrade performance gradually and silently.
Check:Reclaim system flow-meter data · municipal water-meter input · discharge-meter output · third-party verification log · maintenance/cleaning records · upcoming retrofit deadline (e.g., CA Title 22 Jan 2027)

Real estate + lease
Read the ground lease for change-of-control + assignment provisions
Why:Ground leases with landlord-consent clauses are the #1 transferability risk in the vertical (per Q1 2026 deal evidence). Landlord can block assignment or extract a CoC fee; pre-negotiated consent before LOI is the highest-ROI Transferability investment.
Check:Lease assignment / change-of-control clause · landlord consent precedent · related-party landlord disclosure · remaining term · option rights · CAM and tax pass-through structures
critical
Transferability
Confirm property tax assessment + appeal history
Why:Property tax on owned car wash sites is material (1–3% of site value annually). Assessment appeals and reassessments at change of ownership can shift property tax materially; pre-close planning recovers value.
Check:Property tax assessments 5 yr · appeal history · reassessment trigger at ownership change · municipal valuation methodology · neighbor-site assessments for comp

Confirm signage and brand-display rights
Why:Site signage (monument, building, road-direction) often falls under municipal sign permits and franchise/branded-program exclusivity. Brand changes at acquisition can trigger re-permitting and brand-program renegotiation.

Operations + KPIs
Test membership conversion rate per site manager
Why:Site manager retention drives membership conversion rate continuity. Conversion rate above 35% on first-time-customer interactions indicates organic sales process; below 25% signals dependency on promotional pricing or aggressive discount-driven acquisition.
Check:POS membership-conversion data per shift / per site manager · trailing 12-month conversion trend · site manager tenure · retention agreement terms post-close

Pricing
Verify POS / membership platform contracts and data ownership
Why:POS and membership-management platforms (DRB, Sonny's CarWash Controls, Washify) hold the membership database and conversion KPIs. Contract terms include data export rights, SaaS termination clauses, and data ownership — loss of historical cohort data destroys forward underwrite.
Check:POS/membership platform contract terms · data export rights · cancellation/termination clauses · uptime SLA · API access
medium
Transferability
Confirm CC processing rates + chargeback history
Why:Card processing is the membership platform's lifeblood; rates above 2.5% materially compress margin. Chargeback rate above 1% signals customer-service friction or membership cancellation friction.
Stress-test peak-hour throughput vs. equipment capacity
Why:Express tunnels are throughput-constrained; sites that report >100K annual cars typically operate near peak-hour capacity. Capacity headroom is the growth constraint that buyers underwrite.
Check:Trailing 12-month per-day car counts · peak-hour throughput · equipment cycle time · queue length data · capacity-utilization estimate
medium
Pricing
Audit revenue per car (RPC) and per-day-volume by day-of-week + season
Why:Headline annual car count obscures throughput volatility. Sites with 100K annual cars but 60% concentration in 3 summer months carry seasonal risk that doesn't show up in flat EBITDA. Day-of-week skew (weekend-heavy vs. commuter-corridor weekday) determines staffing and chemical demand.
Verify mobile app download + retention metrics for membership funnel
Why:Modern express tunnel platforms (Mister, Tommy's, Whistle Express) drive membership conversion through mobile apps. App download rate, sign-up completion, and 30-day active rate are the operating-quality indicators upstream of the cohort retention numbers buyers underwrite.
Reconcile RFID tag inventory with active membership count
Why:Express tunnel members are typically issued an RFID tag for entry; gap between RFID inventory issued and active memberships flags either duplicate active members, lost-tag turnover, or accounting irregularities in the membership platform.
Check:RFID tag inventory issued vs returned · active membership count · duplicate-vehicle membership records · tag-replacement charge revenue

Equipment + capex
Inventory wash equipment age + remaining useful life
Why:Express tunnel equipment (conveyors, applicators, blowers) typically has 7–12 year useful life; replacement cost runs $1.5M–$4M. Sites with equipment near end of life carry forward capex that prices into the offer.
Check:Equipment list with manufacturer (Sonny's, MacNeil, Tommy Car Wash Systems), install date, remaining useful life · maintenance/repair history · upcoming replacement schedule · capex reserve adequacy

Verify equipment manufacturer warranties and service contracts
Why:Tunnel equipment (Sonny's, MacNeil, Tommy Car Wash Systems) carries OEM warranties and optional service contracts. Warranty transfer at change of ownership is not automatic; gap means forward maintenance cost on the buyer.
Check:OEM warranty terms by equipment serial · service contract terms + transferability · OEM authorization for parts/service · pre-paid service hours remaining

Transferability
Inspect chemical applicator and dosing system calibration
Why:Chemical over-dosing is the leading silent-margin-killer in this vertical. A site with dosing drift from spec ranges runs 20–40% above target chemical cost without operating impact visible to the operator. Calibration cadence + in-line monitoring catches it.
Check:Chemical applicator service records · dosing-system calibration log · chemical consumption per car (oz/wash) vs target · trailing 12-month chemical cost variance
Why:Express tunnel customer base is typically diffuse, but corporate fleet accounts (commercial van fleets, dealer detail programs) concentrate revenue. Single account >10% of revenue is a transferability risk — relationships rarely transfer cleanly.
Why:Fleet accounts (UPS, Amazon DSP, dealer-group detail) generate stable revenue but carry contract-renewal risk at change of ownership. Verbal commitments and handshake agreements do not survive transaction.
Confirm GL, pollution liability, and umbrella insurance coverage
Why:Standard GL alone does not cover stormwater discharge liability, PFAS exposure, or chemical handling. Pollution Liability rider is essential; under-insurance flags forward premium increase and lender-required gap coverage.
Check:Certificates of Insurance · Contractors Pollution Liability (CPL) limits · environmental impairment liability · umbrella policy · loss runs 5 yr
Why:X-Mod above 1.0 signals injury frequency above industry average and predicts forward premium; modifiers are sticky 3 years post-close. Wash attendant role has elevated injury frequency (slip/fall, chemical exposure).
Check:NCCI X-Mod worksheet · trailing 5-year claims · OSHA 300 log · safety program documentation · chemical exposure incident history
medium
Transferability
Verify Vehicle Damage Liability + comprehensive auto insurance
Why:Vehicle damage claims (scratches, mirror impacts, antenna damage) are the second-most-frequent claim category after slip-falls. Standard GL excludes vehicle-in-care coverage; specific Vehicle Damage Liability rider is industry-standard.
Why:Express tunnel attendant turnover is 65–95% annually — structurally high for the vertical. Recruiting infrastructure (job boards, applicant tracking, onboarding) determines whether the model continues to fill positions post-close. Gap means rapid labor crisis post-close.
Check:Trailing 24-month turnover by role · open requisition count · time-to-fill metrics · onboarding curriculum · trainer/lead-attendant tenure
medium
Transferability
Audit OSHA HazCom training records + chemical exposure incident history
Why:OSHA Hazard Communication Standard requires documented training for staff handling chemicals (surfactants, polymers, drying agents). Training-record gaps are findings at lender Phase I review and at insurance underwriting; chemical-exposure incidents drive worker comp premium.
Check:HazCom training records by employee · trainer certification · refresher cadence · chemical-exposure incident reports (OSHA 300) · medical evaluations triggered

Transferability
Verify slip-fall safety protocols and incident response training
Why:Slip-fall claims are the modal litigation category in the vertical. Sites with documented safety protocols (entry-area mats, signage, scheduled wet-area cleaning, employee training) experience 40–60% lower claim frequency than sites without.

Working capital + balance sheet
Age accounts receivable + bad-debt write-offs
Why:Express tunnel AR is light (mostly card-on-file recurring); but fleet/B2B accounts can carry 30–60 day AR. Underestimating collectibility overstates working-capital target at close.
Verify state sales tax nexus (multi-state operators)
Why:Sales tax rules vary widely (some states tax wash services; others exempt). Multi-state operators face nexus complexity; back-tax exposure is a finding at SBA underwriting.
Check:Sales tax returns 3 yr per state · taxability matrix per state · audit notices or assessments · nexus determination memos
Why:Car wash transactions financed via SBA 7(a) (NAICS 811192) require eligibility verification: Phase I clean, no prohibited business activity, and lender-specific overlays. SBA SOP 50 10 8 (2023) introduced add-back stripping conventions that materially affect presented SDE/EBITDA.

Franchise + brand programs
Read franchise agreement (Tommy's Express, Take 5, etc.) for assignment
Why:Franchise-format sites carry assignment restrictions, royalty obligations, and territory restrictions that travel with the site. CoC consent and territory-encroachment language are deal-blockers when missed.
Why:POS/membership platforms are sticky — switching costs include data migration, staff retraining, hardware replacement. DRB and Sonny's CarWash Controls dominate; switching from one to the other typically costs $40K–$120K per site plus 4–8 weeks of operational disruption.
Check:Platform contract term + auto-renewal clause · data export rights · switching cost estimate · API access for integrations · uptime SLA + historical outages
medium
Transferability
Confirm branded chemical program economics + termination provisions
Why:Branded chemical programs (Lustra Professional, Sonny's Direct) bundle chemicals with brand signage and POS rebates. Terminating mid-contract typically triggers minimum-volume penalties or rebate clawbacks. Switching after acquisition without diligence costs $50K–$150K in penalty + rebrand.
Check:Chemical program contract · annual minimum volumes · rebate structure · brand signage rights tied to program · termination notice period + penalty schedule

Why:JP in-bay automatic and tunnel sites with refrigeration equipment (water-temperature management, dryer systems) fall under the Fluorocarbon Act's mandatory recovery and inspection regime. Penalties up to ¥500,000 per violation; missing recovery records block commercial-account renewals.
Confirm Construction Business Act (建設業許可) licensure for JP construction-tied sites
Why:JP car wash sites that include facility expansion, ducting modification, or significant on-site construction require 管工事業 or 建築工事業 license under the Construction Business Act. Operating outside licensed scope is a strict-liability finding.

Map JP relationship-banking structure and CoC consent rights
Why:JP SMB acquisitions typically rely on relationship-based regional bank financing (地銀 / 信金) rather than a national SBA-equivalent. Existing main-bank relationships (メインバンク) often hold change-of-control consent rights via loan covenant; loss can compress working capital independent of credit metrics.
Check:Main-bank loan agreements with CoC clauses · personal guarantee (個人保証) by selling shareholder · relationship history with regional bank · 信用保証協会 (credit guarantee corporation) coverage · post-close lender continuation letter
Why:Japan's 終身雇用 (lifetime employment) convention and Article 16 of the Labor Contract Act make termination far harder than at-will US employment. Severance reserves, social insurance employer contributions (~15% of wages), and statutory retirement pay obligations are often understated on US-style management accounts.
Inspect 商業登記 (commercial registry) and 印鑑証明 (seal certificate) for JP corporate transactions
Why:JP corporate transactions require fresh 履歴事項全部証明書 (commercial register full extract) and 印鑑証明書 (registered seal certificate); outstanding director changes or unfiled capital actions are blocking findings at signing.

Confirm JP electrical work license (電気工事業) for sites with 200V wiring
Why:JP car wash installations involving 200V wiring or panel work require 第二種電気工事士 (Class-2 Electrician) license per the Electrician Act (電気工事士法), and the entity itself needs 電気工事業登録 (Electrical Construction Business registration). License-by-tech is not portable across jurisdictions in the way US masters can be.
