Buying an HVAC company on a diligence budget that could not stretch

The situation

The email from Sari's lawyer arrived two days after the data room opened, and it was shorter than anyone expected. Chidi would have access to a defined set of summary financials, contracts, and equipment lists. Anything beyond that, the full general ledger, customer-level pricing, supplier terms, and payroll detail, would be available only to Chidi's own lawyer and accountant, under a confidentiality undertaking, and could not be shared with Chidi himself until closing. Sari's reasoning, relayed through her lawyer, was straightforward: Chidi had spent nine years working as an HVAC technician for a competing mechanical contractor two towns over, and Sari was not willing to hand her sharpest competitor a detailed look at her pricing and customer list if the deal fell through.

Chidi had come to Canada a decade earlier and spent those nine years learning the mechanical trade from the inside, first as an apprentice and eventually running service calls independently across the region around Bancroft. His wife Indah worked as a registered nurse, and it was her steady income, along with years of careful saving, that had let Chidi assemble enough for a down payment on a business of his own rather than staying an employee indefinitely. The company he had found, a well-established residential and light commercial HVAC contractor, was priced in the upper six figures to low seven figures, financed through a combination of savings, a vendor take-back from Sari, and a modest small business loan that had taken months to arrange.

The financing itself had left very little room for anything else. Chidi's loan had been approved on the assumption that legal and accounting costs would stay modest, and he had budgeted for a standard diligence review, not a negotiation over who was even allowed to see the numbers. Sari's restriction threatened to turn a straightforward, if careful, review into a legal argument about access rights, the kind of fight that could easily cost more in professional fees than the information gained was worth.

Chidi's instinct, understandably, was to push back hard. He was the one putting his savings and his family's financial security into this purchase, and being told he could not personally see the full financial picture of the business he was about to own felt backwards. But every hour spent arguing about access was an hour billed against a diligence budget that had almost no slack left in it, and Sari's concern about protecting her business from a competitor who might walk away was not unreasonable on its face either.

Why this was harder than it looked

A tiered data room, where advisors see more than the buyer does directly, is not unusual in a sale between competitors or near-competitors, and it exists for a legitimate reason. A seller who opens her full books to someone who could become her next-door rival, only to have that buyer walk away from the deal, has handed over a competitive advantage for nothing. Restricting direct access to counsel and accountants under confidentiality obligations, while still allowing those advisors to review everything and report findings back in summary form, is a recognized way to balance a seller's protection against a buyer's need for real diligence.

The difficulty for Chidi was not the structure itself, which was reasonable, but what it meant for a buyer without money to spend on redundant review. In a typical file, we would review the full financial detail ourselves, flag issues, and walk the client through anything material in plain language, while the client also formed their own impressions from seeing the numbers directly. Here, Chidi could not do that second part at all. Every risk we identified had to be explained to him in enough detail that he could make a real decision without ever seeing the underlying document that generated the concern, which meant the way we communicated findings mattered as much as the findings themselves.

The tight budget compounded the problem. A full line-by-line review of years of general ledger detail, customer contracts, and supplier terms for a business this size would normally take a meaningful number of billable hours, and Chidi could not afford that scope even if Sari had allowed him to see everything directly. We could not simply throw more review time at the restricted-access problem to compensate for Chidi's limited visibility. The diligence had to be narrower than ideal in scope while still catching the handful of issues that could actually sink the deal or the business afterward, which meant every hour of review needed to be aimed at the highest-risk areas rather than spread evenly across the whole file.

There was also a trust dimension underneath the legal one. Chidi was being asked to commit most of what he owned to a business based substantially on his advisors' word rather than his own direct review, from a seller who had already signalled she saw him as a competitive threat. Making that arrangement feel workable to Chidi, not just legally sound, took as much effort as the diligence itself.

What we did

1. Negotiated the scope of the tiered access rather than fighting it outright. Instead of contesting Sari's right to restrict access, which would have burned significant budget with no guarantee of a clear win, we negotiated exactly what fell into the restricted tier and confirmed Chidi could see everything else, including the summary financials, existing contracts, and equipment lists, directly, immediately, and without any delay or approval process.
2. Built a risk-ranked diligence checklist before opening a single document. With limited hours available and no room for wasted review time, we identified the handful of issues that would actually change Chidi's decision to close or the price he was willing to pay, such as customer concentration, supplier contract terms, and any pending equipment liabilities, and directed the review toward those first rather than working through the data room in whatever order it happened to be organized.
3. Reviewed the restricted-tier documents ourselves and reported findings in structured written summaries. Since Chidi could not see the underlying general ledger and customer files directly under the confidentiality undertaking, we prepared clear, specific written summaries of everything we found, flagging anything material in plain, non-technical terms he could actually act on without ever needing to see the source document himself.
4. Verified customer concentration without exposing customer identities to Chidi. We confirmed, using percentages and broad categories rather than naming any of Sari's actual clients, how much of the business's revenue depended on its largest few accounts, giving Chidi the risk picture he genuinely needed while still fully respecting the confidentiality restriction Sari had insisted on from the outset.
5. Capped our own review hours against a fixed budget agreed with Chidi upfront. Rather than letting the diligence scope quietly expand every time a new question surfaced, we set firm hour limits by category at the very start and flagged to Chidi whenever we were approaching one, so he always knew what remained affordable to check and what would ultimately have to be accepted on more limited assurance instead.
6. Negotiated a modest holdback tied to specific representations instead of full open-book verification. Where the budget simply did not allow us to independently confirm every figure Sari provided, we negotiated a holdback of part of the purchase price, to be released after closing once certain financial representations proved accurate over time, giving Chidi a partial backstop in place of the direct verification he could not afford to fund.
7. Advised Chidi plainly on what remained unverified at closing. Before he signed anything, we gave Chidi a clear written list of exactly what our limited-scope review had and had not covered, so he understood precisely where the residual risk sat rather than assuming the diligence had been as thorough as a standard, better-funded file would ordinarily have been.

The outcome

The deal closed on the timeline Chidi needed, with the tiered access protocol holding through to completion and no breach of the confidentiality undertaking on either side. Chidi took over the business having seen the full financial picture only through our summaries rather than directly, which was a real compromise from what a buyer would ideally want before committing most of his savings to a purchase.

The holdback we negotiated gave Chidi some protection against the risk that came from the limited-scope review, and a modest portion of the purchase price remained tied to the accuracy of Sari's representations for several months after closing. That was not a full substitute for independent verification, and we told Chidi clearly that some risk, particularly around the smaller supplier contracts we did not have budget to review in full, was going into the deal unexamined rather than confirmed safe.

In the months after closing, the business performed largely as the summary financials had indicated, and no issue arose within the holdback period that required Chidi to make a claim against it. That outcome does not mean the narrower diligence was without cost. Chidi bought the business with less certainty than a fully funded review would have given him, and the compromise reflected the reality of what he could afford, not the diligence he would have chosen if money had not been a constraint.

Two of the smaller supplier contracts we had flagged as unreviewed at closing later turned out to contain renewal terms less favourable than Chidi would have negotiated himself, a modest ongoing cost rather than a crisis, but a real one, and exactly the kind of gap our written summary had told him to expect going in. He told us afterward that knowing precisely where that gap sat, rather than discovering it cold months later, was what let him absorb it as a manageable cost of doing business instead of a betrayal by advisors he had trusted with money he could not afford to lose.

For a buyer entering his first business purchase in a new country, on a tight budget and against a seller who saw him as competition, closing on workable terms rather than walking away or overspending on review was, on balance, the right trade to make.
