Two Weeks to Replace Twelve Years of Supply

The situation

For twelve years, Beth's supply business had one arrangement it never worried about. A mid-sized general contractor placed standing weekly orders for the specialty fasteners and hardware Beth's company sourced and warehoused, an arrangement that had grown from a small trial order into roughly forty percent of her company's annual revenue. There had never been a written supply agreement. Orders came in by phone or email, invoices went out on the usual terms, and both sides simply kept renewing the relationship year after year by continuing to show up, order after order, without either side ever pausing to write down what either was actually promising the other.

Beth, who also worked full time as a construction project manager and ran the supply business on evenings and weekends with her husband Biniam, a chiropractor, treated the arrangement as one of the steady, dependable parts of the business, the kind of account you plan the rest of your year around rather than one you question. New equipment purchases, warehouse lease renewals, and hiring decisions were all made with that contractor's order volume assumed as a given, the same way a household budgets around a salary that has never once been late.

The plan, as far as Beth had one, was simple: keep service reliable, keep prices competitive, and the relationship would keep renewing itself the way it always had. She had raised the idea of putting something in writing a few times over the years, mostly when a new order came in larger than usual and made her briefly nervous about how much rode on an unwritten understanding, but the contractor's purchasing manager always waved it off as unnecessary between two companies who trusted each other, and Beth, not wanting to seem difficult or make the relationship feel transactional, let it drop each time.

Then, on a Thursday in early spring, an email arrived from Halima, a name Beth did not recognize, newly hired to run the contractor's purchasing department, informing her that the company was consolidating its suppliers and that her account would be closed in two weeks. There was no explanation of what had changed, no phone call, and no opening for negotiation in the message itself, just a short notice that ended, on paper at least, a relationship Beth had spent twelve years building her business around.

What the review found

Beth had actually worked with our office once before, about four years earlier, over a much smaller dispute with a different customer who had disputed an invoice. At that time, we had recommended putting the contractor relationship in writing given how much of her revenue it represented, specifically a short supply agreement covering notice periods, minimum order commitments, and what would happen if either side wanted to change the arrangement significantly or wind it down. Beth had agreed it made sense at the time and had never followed through, partly because the business stayed busy and partly because the relationship never seemed to need it, right up until the moment it did.

When we reviewed everything Beth actually had, twelve years of invoices, order emails, and a handful of old price-list negotiations, there was no signed agreement of any kind. What existed instead was a course of dealing: a long, consistent pattern of ordering and supplying that could support an argument that some reasonable notice period was owed, even without a written contract, because Ontario law generally expects a supplier relationship of that length and dependence to be wound down over more than two weeks rather than cut off abruptly and without warning.

The difficulty was that reasonable notice in a case like this is not a fixed number a lawyer can simply look up. It depends on the length of the relationship, how much of Beth's revenue depended on it, how quickly she could realistically replace the volume, and what the contractor knew or should have known about that dependence. Twelve years and forty percent of revenue supported an argument for a meaningfully longer notice period than two weeks, but nothing guaranteed a specific number, and pursuing it fully to a final determination would mean litigation against a much larger company with far more resources to spend fighting it than Beth had to spend pursuing it.

There was also a harder truth underneath the legal analysis, one the review made unavoidable. Because nothing had ever been put in writing, Beth had no minimum order guarantee, no exclusivity, and no contractual claim beyond the notice argument itself. The earlier advice to formalize the relationship had been exactly the protection this situation needed, tailored specifically to a customer this size and this important, and its absence now shaped every option available to her, narrowing what had once been a straightforward fix into a genuine negotiation from a weaker position.

What we did

1. Assembled the full documentary history of the relationship, twelve years of invoices, order confirmations, and email correspondence, to establish the length, consistency, and value of the arrangement as clearly and specifically as possible, since that history, in the absence of any written contract, was going to be the strongest evidence available on which to build a claim, and the only real substitute for the agreement that had never been signed.
2. Sent a formal notice letter addressed to Halima in the contractor's purchasing department, asserting that a relationship of this length and dependence required a genuinely reasonable transition period rather than two weeks, and setting out the revenue and operational impact on Beth's business in specific, documented terms rather than a general complaint about unfairness or a plea for a personal favour.
3. Opened a direct negotiation with the contractor's legal counsel once the letter prompted a response, focusing on a realistic and achievable outcome rather than an all-or-nothing fight, since Beth's business needed resolution within weeks to manage cash flow and staffing decisions, not the year or more a full lawsuit against a much larger, better-resourced company could realistically take to work its way through the courts.
4. Assessed Beth's actual ability to replace the lost volume, working through her order books and margins with her directly to understand which parts of the lost revenue could realistically be recovered from other customers within a reasonable window, an analysis that shaped what settlement outcome actually made practical sense to pursue rather than simply demanding the largest figure imaginable.
5. Negotiated an extended transition period in place of the two-week cutoff, giving Beth several additional months of reduced but continuing orders to soften the revenue drop while she actively rebuilt her customer base, rather than pushing for an abrupt end paired with a single cash payment that would have left her with no bridge to new business and no time to rebuild it properly.
6. Advised against pursuing full litigation over the entire lost relationship, given the cost of a multi-year court process, the genuine uncertainty of what a court would actually award for reasonable notice on an unwritten twelve-year arrangement, and the practical value of the certainty a negotiated transition period offered right away, in money the business could actually plan around rather than wait years to possibly collect.
7. Reviewed Beth's other significant customer relationships for the same gap, identifying two additional accounts representing meaningful shares of her revenue that also had no written terms behind them, so the same vulnerability, unwritten and unnoticed for years, would not simply resurface with a different customer once this one had finally been resolved, on terms Beth would not see coming next time either.
8. Drafted a written supply agreement for Beth to use going forward with any customer representing a significant share of her revenue, covering notice periods, minimum order commitments, and a clear process for winding the relationship down if either side ever needed to, so the next relationship of this size would not depend on trust and a handshake alone, no matter how solid that relationship happened to feel at the time.

The outcome

The contractor agreed to an extended transition of several months of reduced orders rather than an immediate cutoff, giving Beth's business real time to actively pursue replacement customers instead of losing forty percent of its revenue overnight. It was not the twelve-year relationship continuing, and it was not full compensation for the value the account would have carried going forward. It was a softened landing, negotiated because Beth had documentation and a credible legal position behind the request, not because the contractor felt it owed her anything it was eager to pay on its own.

By the time the transition period ended, Beth had rebuilt roughly half of the lost order volume with other customers, still leaving the business meaningfully smaller than it had been, with real cuts to staff hours and one seasonal position not renewed that spring. The dispute, valued at somewhere between three hundred fifty thousand and eight hundred thousand dollars in annual revenue exposure depending on how quickly replacement volume could realistically be found, never went to court, and Beth avoided the legal cost and years-long uncertainty a full claim for lost future income would have carried, along with the risk of recovering meaningfully less after all that time and expense.

What stayed with Beth afterward was less the transition period itself and more the memory of having been told, years earlier, exactly what would protect her, and having let it go because the relationship felt too solid, too long-standing, to ever need it. She now has a signed agreement with every customer representing more than a small share of her revenue, reviews them annually rather than letting them sit untouched in a drawer, and no longer treats a good relationship as a substitute for a document that says, in writing, what happens if it ends.
