Operational due diligence, step by step

A business can be financially sound and legally clean and still fail, quietly, in the hands of a new owner because the way it actually operates day to day never got examined closely enough. Operational due diligence is the review that asks a more practical question than financial or legal diligence does: can this business keep running the way it does today, tomorrow, under someone who is not the person who built it? That question is answered by looking at processes, equipment, technology and relationships directly, not by reading a summary someone else wrote about them.

Find out how much of the business lives in one person’s head

Ask for written standard operating procedures, and pay close attention to how much of the operation actually has any documentation behind it versus how much exists only as the owner’s habit and memory. A reasonable test is whether a capable manager could run the daily operation for two or three weeks with the owner genuinely unreachable — not on standby by phone, actually gone. Businesses that fail this test are not necessarily bad businesses, but they are riskier to buy at the same price as ones that pass it, because a real part of what generates the earnings may not transfer with the sale at all. A repair shop where only the owner knows which supplier gives real discounts on which parts, or a service business where only the owner knows which recurring clients quietly expect a discount, is carrying risk that a fixed-asset list and a profit and loss statement will never reveal on their own.

Inspect equipment condition, not just the equipment list

A fixed-asset list tells you what the business owns; it tells you nothing about whether that equipment is near the end of its useful life or has been deferred on maintenance to keep recent earnings looking stronger than they would with proper upkeep. Walk the equipment in person or send someone qualified to do it, and pull maintenance and service records where they exist. Deferred maintenance is one of the more common ways a business’s recent profitability quietly borrows against a buyer’s first year of ownership — the capital expenditure the seller avoided becomes the new owner’s bill almost immediately.

Map how concentrated the customer and supplier base really is

A business where one customer accounts for a large share of revenue, or where a single supplier is the only realistic source for a critical input, carries a structural fragility that does not show up in a single year’s financial statements. Ask for a genuine breakdown of revenue by customer and purchases by supplier, not an assurance that the base is diversified. Losing one relationship out of many is a normal cost of doing business; losing one relationship that represents a large share of everything is closer to losing the deal you thought you bought.

Check the technology and data systems, not just the storefront

Look past the customer-facing side of the business at what actually runs behind it — the age and condition of core software, whether data is genuinely backed up and recoverable, whether software licences are held by the business or personally by the owner, and whether basic cybersecurity practices are in place. A technology stack held together informally, with passwords in someone’s head and no real backup discipline, is a real operational risk that can produce an expensive, disruptive failure well after closing rather than a minor inconvenience during diligence.

Confirm the operation is actually in good standing

In Ontario, a Workplace Safety and Insurance Board clearance certificate confirms the business does not carry unpaid premiums that could attach to the buyer, and its experience rating affects what the new owner will actually pay in premiums going forward — other provinces run their own workers’ compensation systems with different certificates and different rules, so confirm the equivalent process wherever the business actually operates. Ask as well whether any compliance orders, safety inspection findings or regulatory notices are outstanding, since these are operational facts a seller may not volunteer without being asked directly.

Assess whether the location and lease fit how the business runs

This is a different question than whether the lease can legally be assigned, which belongs to legal diligence — here the question is whether the space itself actually works for the business as it operates today. Consider whether the square footage, layout, parking and access genuinely support current and near-term operations, and inspect the condition of any leasehold improvements directly rather than assuming they match what the lease documents describe on paper. A light-manufacturing tenant that has quietly outgrown its floor space, or a service business whose parking has become inadequate as its customer volume grew, can be earning well today while sitting on an operational constraint that will cap growth or force a costly relocation soon after closing.
