Mobile mechanic service due diligence

Due diligence on a mobile mechanic service under a letter of intent centres on three things a fixed shop does not have to prove in the same way: that the booking platform and customer database can actually be transferred, that the online reviews are legally tied to the business rather than the departing technician, and that hazardous-waste and certification records are clean.

Reviewed

Diligence on a mobile mechanic service looks different from diligence on a fixed-location repair shop, because there is so little physical inventory to count and so much riding on intangible systems and relationships. A buyer under a signed letter of intent should spend the diligence period confirming that what was represented during negotiation — a real business-owned booking system, a documented route, business-tied reviews, a clean compliance file — actually holds up under direct verification rather than the seller’s word.

Verify the booking platform and customer database can actually transfer

Request the booking platform’s terms of service and confirm directly with the vendor, not just the seller, that account ownership and the underlying customer data can be transferred to a new owner. Ask for an export of the customer database as it would look the day after closing, and compare it against what has been represented — a database that turns out to be locked to the seller’s personal login, or far thinner than described, changes the value of what is actually being purchased.

Match the van and equipment on the purchase agreement against what actually exists

Walk through the service van, tools and diagnostic equipment being purchased against the list attached to the purchase agreement, checking vehicle identification, mileage and maintenance records against what has been represented. A vehicle with maintenance gaps or a diagnostic scanner that has not been updated for current model years is not a deal-ending finding on its own, but it is a real cost the buyer will absorb after closing and should be reflected in the price or handled as a condition of closing rather than left as a verbal understanding.

Confirm exactly which reviews are the business’s to keep

Log into the actual review and rating profiles being purchased and confirm they are registered to the business rather than an individual technician’s personal account on the platform. Where a platform ties ratings to the person rather than the listing, that history may simply not transfer no matter what the purchase agreement says, and that is a finding that should change either the price or the deal structure, not just get noted and moved past. Where reviews are split across more than one platform, check each one individually rather than assuming the same ownership pattern holds across all of them.

Confirm technician certification and any municipal licensing directly with the regulator

Confirm the current status of individual technician certification directly with the relevant provincial trades authority rather than relying on a certificate the seller produces, and check with the local municipality whether the mobile-trade or vending-style licence, where one is required, is in good standing and whether it can transfer or must be reapplied for by the buyer. A lapsed certification or licence is a straightforward fix, but only if it is caught before closing rather than after.

Check the hazardous-waste and used-oil handling record

Request the business’s records for how used oil and other automotive fluids have been collected and disposed of, since provincial hazardous-waste rules apply to a mobile operation even without a fixed premises. A clean record confirms the operation has been run properly; any history of violations is a red flag disproportionate to the size of the business, because it points to a compliance culture the buyer will inherit along with the customer list.

Search for liens against the van and equipment before you pay for them

Run a personal property security search against the van and any financed equipment to confirm the seller actually owns them outright, or to identify what has to be paid out at closing if a lender still holds security over them. A search that turns up an undisclosed lien is not automatically a reason to walk away, but it is a reason to make payout of that lien a condition of closing rather than take the seller’s word that everything is clear.

Confirm employment and workplace-insurance standing

Where the business has any employees, confirm workplace-insurance clearance directly with the relevant provincial board before closing, since outstanding obligations tied to the business can otherwise follow the buyer. Review any existing employment terms for technicians the buyer intends to keep, and get clarity in writing on whether the seller or a current technician will actually stay on through a transition, rather than a verbal assurance made during negotiation — a signed retention commitment is worth more at this stage than a promise made across the table.

Findings that typically end a deal in this sub-sector

The recurring findings that stop a mobile mechanic acquisition are a customer database that will not actually transfer, reviews that are legally stuck with the departing technician, an operation that turns out not to be properly certified or licensed, or an unresolved history of hazardous-waste violations. None of these are necessarily visible from the outside during negotiation, which is exactly why a genuine diligence process, rather than a quick look at last year’s tax return, matters so much more here than it does for a business with real physical assets. Surfacing a problem before closing is far cheaper than discovering it after.
