If you run an HVAC company, a landscaping business, or any trade with a clear busy season, you know the feeling: November was great, December was great, and by mid-February your bank account feels like a disaster. The business didn't actually go backwards. Cash flow and profitability are two different things — and confusing them is what kills otherwise healthy businesses.
Profit is a story. Cash is a fact.
Profit tells you whether the business made money over a period. Cash tells you whether you can pay your bills this week. They move on different clocks. A seasonal business often books its biggest revenue in summer (or winter, for heating-focused shops) but pays its real costs — payroll, insurance, vehicles — every month of the year.
Build the reserve before you need it
The simplest fix is also the hardest: during your busy season, move a percentage of every deposit into a separate account and do not touch it. We coach most clients toward a 2–3 month operating reserve — enough to cover payroll, insurance, and fixed costs through the lean months without borrowing.
Watch the 13-week forecast
A 13-week cash forecast is the single most useful tool for seasonal businesses. It projects inflows and outflows week-by-week for the next quarter and lights up problems before they become urgent. We set this up for every ongoing client and review it together monthly.
The other levers
- Invoice same-day and follow up on receivables aggressively.
- Negotiate longer payment terms with suppliers during slow months.
- Smooth insurance premiums into monthly payments where possible.
- Use a business line of credit as a bridge — not as a substitute for a reserve.
Q1 tight is a symptom. The fix isn't to hustle harder in January — it's to build the system that makes February predictable.
