A practical due diligence guide for buyers evaluating mobile detailing acquisitions — from fleet contracts and equipment condition to SBA financing and owner-dependency risk.
Find Mobile Car Detailing Acquisition TargetsMobile car detailing businesses trade at 2.5–4x SDE, but quality varies dramatically. Before closing, buyers must verify recurring revenue, assess equipment condition, audit technician dependency, and confirm customer relationships will transfer. This guide walks through every critical checkpoint.
Confirm the business generates consistent, documented cash flow and that revenue is attributable to systems and clients — not solely the owner's personal hustle.
Cross-reference deposits against reported revenue to identify cash transactions, seasonal dips, and undisclosed client losses that tax returns alone won't reveal.
Request a CPA-prepared SDE add-back schedule identifying owner compensation, personal vehicle expenses, and one-time costs that inflate or deflate true earnings.
Obtain copies of all signed fleet or dealership service agreements and confirm recurring monthly billings match the seller's claimed contract revenue figures.
Evaluate whether the business can operate without the owner and whether the physical assets are in a condition that won't require immediate capital expenditure post-close.
Commission a third-party mechanic inspection on each van. Assess water tank integrity, pump systems, and generator condition — replacement costs run $15K–$40K per unit.
Confirm service procedures are documented for each tier — basic wash, full detail, ceramic coating. Verify all bookings are in software like Jobber or HouseCall Pro.
Determine whether technicians are W-2 employees or 1099 contractors, confirm classification compliance, and assess whether key staff will stay post-acquisition.
Ensure the customer base is transferable, diversified, and anchored by reputation and systems — not the seller's personal relationships or phone number.
Flag any single client representing more than 15% of total revenue. Fleet accounts are valuable but create dependency risk if contracts aren't formally transferable to a new owner.
Verify the seller owns the Google Business Profile, Yelp listing, and social media accounts. Confirm review volume, average rating above 4.5 stars, and profile transferability.
Negotiate a 60–90 day post-close transition with the seller for client introductions, staff communication, and routing handoffs to protect first-year revenue retention.
Verify the Mobile Car Detailing acquisition qualifies for SBA financing, the purchase price is supportable by the verified cash flow, and the deal structure protects the buyer's downside.
Confirm the Mobile Car Detailing meets SBA 7(a) eligibility requirements: the business is for-profit, U.S.-based, within SBA size standards, and the buyer meets personal financial requirements. Some industries have specific SBA restrictions — verify before LOI.
Model verified normalized EBITDA against projected SBA loan payments at current rates. A $1M SBA 7(a) loan at 10.5% over 10 years costs approximately $13,000/month. The Mobile Car Detailing must generate at least 1.25x debt service coverage after a market-rate manager salary to pass underwriting.
Confirm the seller note is properly subordinated to the SBA loan and goes on 24-month standby as required by SBA rules. If an earnout is included, define exact measurement metrics, time period, and dispute resolution process before signing the purchase agreement.
Before signing a Letter of Intent, request these documents from the seller. Missing or incomplete items are a red flag — not a reason to proceed without them.
SBA 7(a) loans are the most common financing vehicle, covering 70–80% of the purchase price. Buyers typically need 10–20% down and two years of profitable business tax returns to qualify.
If the owner performs over 50% of billable work, holds all client relationships personally, or has no lead technician, expect significant goodwill discount and negotiate a structured earnout to offset risk.
Most mobile detailing businesses sell at 2.5–4x SDE. Businesses with fleet contracts, W-2 employees, and 200-plus Google reviews command the higher end. Solo-operator businesses with cash revenue sell at the low end.
Structure 10–20% of the purchase price as a seller note tied to customer retention milestones at 6 and 12 months post-close. This aligns the seller's incentive with a smooth client transition.
