Coolgardie Commercial Refrigeration

From emergency call-outs to equipment that keeps running

For trades and service business owners5-minute summaryUpdated October 2026

Coolgardie, its owner Jason, customers and all figures are invented. It is the fictional business that runs through The Founder’s Trap.

Jason’s business keeps cool rooms and display fridges running for cafés, small grocers and a couple of pubs across a regional city. It has a good reputation and more work than it can comfortably handle—yet revenue is up and profit is flat. The largest customer, a small supermarket group, wants keener rates, and the parts distributor has raised its prices. Jason keeps noticing that customers aren’t really buying repairs: they want to avoid a cool room failing over a long weekend.

What the case found

  • Every competitor’s value curve looks the same. Operators compete on hourly rate, breadth of equipment, call-out speed and per-job quotes, so customers compare on price. A planned-maintenance offer raises scheduling clarity, preventive planning with IoT temperature sensors, service history and budget certainty instead.
  • A fixed-price promise lives or dies on breakdowns. At an illustrative A$220 a month, a site keeps A$1,080 a year as contribution with no breakdowns. Each breakdown call-out costs A$280, so a site priced on two breakdowns contributes A$520, and at four it loses money.
  • Two holdups look like successes. A supermarket group approaching a third of billed hours, and a single compressor distributor with no alternative trialled, both set more of Coolgardie’s terms each year.
  • The business runs on Jason’s head. Scheduling, scoping tricky jobs and reassuring customers all depend on him. A business whose reliability rests with one person is selling a promise of reliability—and someone has to answer a sensor alert at two in the morning.
The structural question

Can Coolgardie keep its customers’ equipment running for a predictable price—without the promise depending on one person’s day?

Key ideas in this case

  • Contribution — what is left from the plan fee after the costs of serving a site; it still has to cover overheads before any profit.
  • The Holdup Trap — when a large customer or single supplier gains enough leverage to set the terms.
  • The Fragility Trap — when essential work cannot happen without one person, and no buffer stands behind them.
