Due diligence on an auto repair business

Due diligence on a repair shop is where a buyer finds out whether the business behind the listing matches the business on paper. Beyond the usual review of financial statements and contracts, a repair shop demands its own checklist: equipment condition, environmental exposure, licensing status, and how much of the shop’s value actually depends on people and relationships that might not survive the sale.

Verify the financial picture line by line

Request several years of financial statements, tax filings and bank statements, and reconcile them against each other rather than accepting a single seller-prepared summary. Look closely at labour versus parts revenue, at how consistently parts are marked up, and at any add-backs the seller has proposed — every add-back should be traceable to an actual document, not simply asserted. Bank deposit records, reconciled against the point-of-sale system, are one of the more reliable ways to confirm that reported revenue actually reached the business rather than being adjusted after the fact.

Get an independent read on the equipment

A shop’s lifts, scanners and specialty tools are working capital, not decoration, and their condition affects both what the business can do on day one and what the buyer will need to spend soon after closing. Bring in a technician or equipment appraiser who doesn’t work for the seller, ask for maintenance and calibration logs, and treat any major equipment nearing replacement age as a live issue in negotiations, not a footnote. Ask specifically whether any equipment is leased rather than owned, since a lease that doesn’t transfer cleanly can leave a buyer without a tool the shop depends on.

Commission an environmental review of the site

Any shop handling waste oil, solvents, coolant or refrigerants, or with any history of underground or aboveground storage tanks, carries environmental exposure that doesn’t show up on a balance sheet. A Phase I environmental site assessment, and a Phase II if the first one flags concerns, gives a buyer and their lender a documented picture of what they’re taking on, and it can surface issues while there’s still room to negotiate or walk away.

Confirm licensing status directly with the regulator

Don’t rely on the seller’s description of how registration works. Contact the relevant provincial regulator directly — OMVIC in Ontario, or the equivalent body elsewhere — to confirm what a buyer needs to do to operate legally after closing, and build the timeline for that application into the closing schedule rather than assuming it happens automatically alongside the paperwork. Get any confirmation from the regulator in writing where possible, rather than relying on a verbal assurance that may not reflect the buyer’s actual eligibility.

Pressure-test the seller’s growth story

Sellers sometimes present a shop’s trajectory in the most favourable light, highlighting a strong recent month or a new service line without mentioning a longer-term decline in core repair volume. Ask for monthly, not just annual, figures over several years, and look at trends in customer count and average ticket size separately from total revenue, since a shop can show flat revenue while actually losing customers and making it up with higher prices per visit. A buyer who understands the real trend, rather than the seller’s summary of it, is better placed to negotiate and to plan for the business they’re actually taking on.

Map how dependent the business is on specific people

Identify whether the shop’s revenue rests heavily on the owner’s own technical work, a single senior technician, or a small handful of long-standing customer relationships. Ask directly whether key employees intend to stay through and after the transition, and whether the top few customers by revenue have any reason to leave once ownership changes — customer concentration and key-person dependence are two of the most common reasons a shop’s post-sale performance disappoints a new owner.

Review the lease and any assignable contracts

If the shop operates from leased premises, confirm whether the lease can actually be assigned to a buyer, whether the landlord’s consent is required, and what condition the space needs to be returned in if the lease ever ends. Do the same for supplier accounts, service contracts and any equipment leases — contracts that look routine sometimes contain assignment restrictions that only surface once someone reads them closely.

Give the process the time it actually needs

Rushing diligence on a repair shop to meet an arbitrary closing date is how equipment problems, environmental issues and licensing gaps get missed. A realistic diligence period leaves room for an equipment inspection, an environmental assessment and a regulator conversation to actually happen and produce answers, rather than being compressed into a checklist that gets ticked off without being properly investigated. A seller genuinely motivated to sell should not object to a diligence timeline built around getting real answers rather than a symbolic checklist.
