Surviving the slow season without panic
If December is scary every year, the problem is in July, not December.
Build a slow-season fund in the busy months
Move a fixed percentage of busy-season revenue (often 5 to 10%) into a separate account every week. Don't touch it. The fund makes the slow months a glide, not a crash.
Cut variable costs before fixed
Slow season is the wrong time to cancel insurance or downgrade software. It's the right time to pause marketing experiments, defer non-urgent purchases, and tighten subs.
Use the slow time on purpose
Annual price review, SOP cleanup, equipment PM, team training. The shops that come out of slow season fastest used the lull, instead of waiting it out.
