Selling

Why your accountant alone is not enough for a sale

A trusted accountant is essential to a sale and structurally unequipped to run one alone, since a sale needs a team, not one advisor.

By ··5 min read

A common pattern among first-time sellers is leaning entirely on the accountant who has handled the business’s books for years, on the reasonable assumption that whoever knows the numbers best is best positioned to guide a sale. That trust is usually well placed for what it covers, and it does not cover everything a sale actually requires. An accountant who has spent years on compliance work, annual filings, payroll, GST/HST returns, is deeply useful for making sense of what the numbers say. A sale is not only a numbers problem. It is a legal transaction, a negotiation, and a process with its own sequencing, and treating a single trusted advisor as sufficient for all three is one of the more common ways sellers end up underprepared for parts of the process nobody warned them about.

What falls outside an accountant’s usual scope

  • The purchase agreement itself, including representations, warranties, indemnities, and how liability is allocated between buyer and seller after closing, which is a lawyer’s domain, not an accountant’s
  • Employment obligations tied to the sale, including what happens to staff, what notice or continuity rules apply, and how those risks differ between an asset sale and a share sale
  • Lease assignment, landlord consent, and any change-of-control clauses buried in a commercial lease that could otherwise surprise both sides late in the process
  • The negotiation itself, structuring a deal, managing competing buyer interest, knowing what terms are market-standard versus unusual, which is closer to a broker’s or M&A advisor’s expertise than an accountant’s

Why this gap catches owners off guard

Part of the reason owners lean so heavily on one advisor is that the accountant relationship is usually the deepest and longest-standing professional relationship a small business owner has, built over years of routine filings long before a sale was ever discussed. That familiarity is genuinely valuable, and it can also create a false sense that the relationship covers more ground than it does, simply because it is the relationship the owner trusts most. An accountant who is candid about the edges of their own role, this is where you need a lawyer, this is where a broker’s market read matters more than my read of the numbers, is doing the owner a real service, but not every accountant volunteers that boundary clearly, and not every owner thinks to ask where it sits.

The practical fix is not to distrust the accountant relationship, it is to build a deal team around it rather than instead of it. That typically means bringing in a lawyer experienced in business sales at least by the time a letter of intent is on the table, and, depending on the size and complexity of the sale, a broker or advisor who can speak to market pricing and buyer behaviour in a way a compliance-focused accountant, however good, is not necessarily positioned to. Deavo is a listings platform, not a broker or advisor, and does not fill this role for any transaction, but the businesses that move through a sale with the fewest unpleasant surprises are consistently the ones where an owner assembled the right small team early, rather than the ones where a single trusted advisor was asked to cover ground outside their usual practice.

What a good handoff between advisors actually looks like

The owners who navigate this well are rarely the ones with the most impressive individual advisors. They are the ones who get their advisors talking to each other directly rather than relaying information through the owner as a middleman, since an accountant who understands what the lawyer is trying to protect against in the purchase agreement, or a lawyer who understands why the accountant structured an add-back a certain way, catches inconsistencies neither would spot working in isolation. An owner’s actual job through this process is less about being the most informed person in the room, which is an unrealistic standard for a first-time seller, and more about convening the right people early and making sure they are actually coordinating, rather than assuming that because each advisor is competent individually, the sale as a whole is being handled competently. A short call at the outset, introducing the accountant and the lawyer to each other and to the broader shape of the sale, tends to prevent far more friction than it costs in time.
