Construction Seasonal
Cash Flow.
Seasonal cash flow is a defining financial challenge for construction subcontractors in most of the US. Winter slows work. Spring ramps up fast. The gap between summer peak cash and winter trough can be $200K–$500K for a $5M contractor — and most experience it as a crisis rather than a planned event. Here's how to manage it deliberately.

What We See in This Business
01
Every Winter Is a Financial Emergency
A slow season that's predictable every year is not a surprise — it's a planning failure. If you know work slows down from November through February, the cash to cover that period should be built during the busy season. Most contractors build cash in the summer and spend it throughout the year without deliberately preserving what they'll need for the slow months.
02
You Don't Know What Your True Seasonal Low Is
Without a 24-month cash flow forecast, you don't know what your cash position will be at the bottom of your seasonal trough — only that it will be lower than summer. Not knowing the specific number means you can't plan specifically. The difference between a $150K seasonal trough and a $50K trough changes every financial decision between July and December.
03
Spring Ramp-Up Strains Cash Too
The beginning of the busy season creates its own cash challenge — new project mobilizations hit before the first pay apps are collected. A contractor who depleted cash over winter and then mobilizes three new jobs in April is facing cash strain from both directions simultaneously.
How SPM Fixes It
Building a Seasonal Cash Reserve Deliberately
The 24-month cash flow forecast shows your projected seasonal trough. The difference between your minimum operating cash requirement and that trough number is your seasonal reserve target. During summer months when cash is accumulating, SPM helps Executive clients identify the reserve target and manage distributions to ensure the reserve is funded before the slow season arrives.
Sweep Account Strategy for Seasonal Reserves
Excess cash above the operating floor during the busy season belongs in a business sweep account or high-yield savings — earning yield while it waits for slow season. The 24-month forecast tells you exactly when you'll need it back. Money sitting idle in checking earns nothing and is more likely to get spent on distributions that should have been held.
Line of Credit as Seasonal Bridge — With a Plan
A working capital line is an appropriate tool to bridge a seasonal cash gap — when the draw event is the slow season and the payback event is the spring ramp-up. What it's not appropriate for is covering a slow season gap that exists because summer cash was fully distributed. SPM's Executive cash flow forecasting identifies whether your seasonal cash plan requires a line draw or whether the reserve funded during summer is sufficient.

Common Questions
Straight answers.
How much cash reserve should a construction subcontractor maintain going into winter?
A common benchmark is 8–12 weeks of overhead and fixed costs as a minimum cash reserve entering the slow season. For a contractor with $80K/month in fixed overhead, that's $160K–$240K in reserve. The exact amount depends on your specific slow season duration, whether you have backlog carrying into winter, and your GC payment timing during winter months. SPM calculates the specific target for each Executive client based on their actual cost structure and project pipeline.
What trades are most affected by seasonal cash flow?
Trades most dependent on outdoor work — civil, earthwork, grading, paving, concrete flatwork, SWPPP, masonry — face the most significant seasonal swings in cold climates. Trades that work primarily indoors — electrical, drywall, flooring, mechanical — have less seasonal exposure but still face spring ramp-up cash strain when multiple projects mobilize simultaneously. SPM builds trade-specific seasonal patterns into the 24-month cash flow forecast.
