Seasonal Cash Management

Why this matters

Most field-service trades earn the bulk of their money in a few hot months and limp through the rest. The shops that fail rarely fail in the busy season. They fail in the lean stretch that follows it, when payroll keeps coming but the calls stop. Managing seasonal cash is the difference between owning a business that survives every winter and one that needs a loan every spring.

The core trap: spending peak-season money in peak season

When the phone is ringing and the trucks are full, cash floods in. It feels like the business is thriving, so the natural move is to spend: a new truck, a hire, an equipment upgrade, a bonus. The trap is that some of that cash is not profit. It belongs to the slow months that have not arrived yet.

A useful mental model: your peak season is not just earning this season's money. It is earning the off-season's money too. Treat a portion of every peak invoice as already spoken for.

Build a reserve before you build anything else

The single most important seasonal habit is a cash reserve that carries fixed costs through the slow stretch. Fixed costs are the bills that show up whether or not you turn a wheel: rent, insurance, loan payments, software, a core crew you intend to keep.

• Add up your monthly fixed costs.
• Count how many lean months you realistically face.
• Multiply. That is your floor, the minimum reserve before you spend peak cash on anything optional.

Hold the reserve in a separate account so you are not tempted to count it as spendable. Out of the operating account, out of mind.

Map your cash calendar, not just your work calendar

Cash does not arrive when the work happens. It arrives when customers pay. The gap between finishing a job and getting paid is your collection lag, and it shifts your real cash peak later than your work peak.

Walk twelve months and mark, for each:

• Roughly how busy the month runs (high, medium, low).
• When that month's money actually lands, given your typical collection lag.
• Which big fixed bills fall due (annual insurance, tax payments, license renewals).

This turns a vague sense of "summer is good" into a month-by-month picture of when cash is fat and when it is thin.

Time your big expenses to your fat months

Once you can see the cash calendar, schedule discretionary spending into the surplus, never the deficit.

• Buy equipment and vehicles when the reserve is full and the surplus is real, not on a busy-season impulse.
• Schedule annual prepayments (insurance, software renewals) for a month you know runs flush.
• Push large optional purchases out of the shoulder season, the in-between months where demand is soft and uncertain.

If a big bill is fixed and unavoidable, fund it during peak and set the money aside early so it does not gut a lean month.

Use the slow season to collect, not to coast

A lean month is the worst time to be owed money you have not chased. Before the slowdown hits, tighten collections while customers still associate you with recent work.

• Run an aging report and call anyone past due.
• Offer a small, time-bound incentive to settle old balances if cash is genuinely tight.
• Tighten payment terms going forward so next season's lag is shorter.

Collecting what you already earned is the cheapest cash you will ever raise. It beats borrowing every time.

Plan the off-season spend before the off-season

Lean months still cost money, so decide in advance what they will cost. A simple off-season budget answers three questions: what stays, what pauses, and what the reserve has to cover.

• Stays: core crew, essential insurance, the tools and software the business cannot run without.
• Pauses: seasonal hires, optional subscriptions, discretionary marketing you can throttle.
• Covers: the gap the reserve fills between thin income and unavoidable fixed cost.

Write it down before the slow season starts. Deciding while cash is draining leads to panic cuts that hurt the next peak.

Avoid the borrow-every-spring cycle

Many shops fund their pre-season ramp-up (parts, payroll, marketing) with a loan or a maxed credit line, then spend the whole peak paying it back, then borrow again next spring. It works until one bad season breaks the loop.

The way out is to fund next season's ramp from this season's reserve. The first year is hard because you have no reserve yet. After that, each peak builds the cushion that funds the following peak, and the borrowing shrinks every year until it disappears.
