Due diligence on a retail business

Due diligence on a retail business means verifying reported earnings against tax and sales-tax filings, physically checking inventory condition and turnover, confirming the lease is assignable, reviewing supplier and franchise contracts, and clearing employer obligations before you close.

Reviewed

Retail due diligence has a physical dimension most other small business purchases do not: you can walk the floor, count the stock and watch a shift happen. That is an advantage over diligence on a services business, but it also means there is more to actually check — inventory condition, equipment age, staffing patterns and a lease that has to keep working after the sale. Treat the visible checks and the paper checks as equally important; either one alone will miss real risk.

Reconcile the financials to something outside the seller’s control

Seller-prepared statements are a starting point, not proof. Ask for tax returns that match the financial statements, sales-tax filings that reconcile to reported revenue, and point-of-sale reports covering a full year or more so seasonal patterns are visible rather than hidden. Where the numbers do not line up cleanly, get an explanation in writing before you assume it is a minor timing difference.

Inspect inventory, not just the inventory list

A stock list on paper can hide a store full of dead inventory — stock that is damaged, out of season, or has not sold in a long time and is only worth a fraction of what the books say. Walk the floor and the stockroom, ask about return and write-off policies, and understand how the inventory count and valuation at closing will actually be performed. This is one of the most common sources of post-closing disputes in retail deals, and getting the mechanism agreed in writing avoids most of them.

Read the lease like it is the deal, because it partly is

Confirm remaining term, any renewal options and the rent that applies to them, whether the lease can be assigned without the landlord’s consent, whether that consent can be unreasonably withheld, and whether a new personal guarantee will be required of you. An estoppel certificate from the landlord — confirming rent, term and that there is no existing default — is standard practice and worth insisting on rather than relying on the seller’s summary.

  • Sales-tax filings reconciled to reported revenue for several years
  • Physical inventory walkthrough, not just a paper stock list
  • Lease term, assignment clause and landlord estoppel certificate
  • Supplier, franchise and exclusivity agreements, and whether they assign
  • WSIB or equivalent workplace-insurance clearance where the business has employees

Check franchise, licensing and permit obligations

A retail business often depends on more than a private lease and a supplier list. A franchise agreement, a liquor or food premises licence, or a municipal business licence may need review for whether it transfers with a sale or requires fresh approval from the franchisor or the licensing authority. A franchise agreement in particular often gives the franchisor a right to approve, or refuse, a new owner, and sometimes a right of first refusal to buy the location back itself. Confirm what is transferable, what needs re-application, and how each approval process actually works before you assume the closing timeline in the purchase agreement is realistic.

Read the neighbourhood, not just the ledger

A set of clean financial statements can still sit inside a location that is quietly declining — a nearby anchor tenant closing, a new competitor opening down the block, road construction that will disrupt foot traffic for a season, or a neighbourhood that has been steadily shifting away from the store’s customer base. None of this shows up in a spreadsheet, and sellers do not always volunteer it. Spend time in the neighbourhood at different times of day and week, talk to nearby business owners where you can, and treat the historical numbers as a description of the past rather than a guarantee about what comes next.

Check what you are inheriting as an employer

If the business has staff, confirm there is no outstanding workplace-insurance liability attached to the business before you take it over — a clearance certificate is the standard way sellers demonstrate this in provinces where the coverage is administered by a workers’ compensation board. Review employment records for hours, wages and any grievances, and understand how existing staff’s service and entitlements are expected to carry forward under an asset purchase.

Look at the systems, not just the numbers

Point-of-sale, inventory management, e-commerce integrations and payment processing all touch customer data, and a system that is outdated, unsupported or handled loosely creates real exposure after closing — both operationally and under Canadian privacy obligations for how customer information is collected and used. Ask what customer data the business holds, how it is stored, and whether it transfers with the sale on terms customers would recognize as consistent with what they were told. A dated or poorly maintained system is also a cost you will likely inherit sooner rather than later.
