Plumbing slows in February. HVAC peaks in July. Roofing stops in January. Know your seasonal pattern, model your revenue by month, and see how much pipeline you need to survive slow season and capitalize on peak season before it passes.
Every trade contractor knows their slow season. HVAC guys know February is thin. Roofers know January–March is survival mode. Landscapers know November–March doesn't pay the same. The problem isn't that slow season happens — it's that most contractors don't prepare a month in advance. They wait until revenue drops to start marketing, which means leads close 30–60 days after they needed them. The fix is an 8-week rule: start your slow-season marketing campaign 8 weeks before slow season starts, not when you notice the phone getting quiet.
Peak season revenue looks impressive on paper, but peak season also burns labor, materials, equipment, and owner energy at maximum rate. The cash reserve built in peak season is what funds slow season payroll, equipment maintenance, and marketing. A trade business without a 60–90 day operating reserve entering slow season is one bad month away from crisis. The target: bank 15–20% of peak-season gross before slow season starts. If your peak revenue is $80,000/month and you're spending $75,000, you're not building a reserve — you're treading water with no margin for error.
A service agreement converts unpredictable emergency call revenue into predictable monthly or annual cash. An HVAC company with 200 service agreements at $180/year collects $36,000 annually regardless of season — before a single repair call. Service agreements also generate higher repair revenue because maintained systems fail predictably rather than catastrophically, and customers with agreements call you first. Build your service agreement book aggressively during peak season (when customers are most receptive) to create the baseline revenue that makes slow season survivable without panic pricing or desperate marketing.
