Overhead that’s only reviewed once a year at tax time means months of drift go unnoticed — a rising cost or a forgotten subscription can run for a long time before anyone catches it.
A simple monthly tracking approach
- Categorize overhead into a small number of consistent buckets (rent, software, insurance, admin, etc.) rather than tracking every line item individually
- Compare each category against the prior month and against the same month last year, not just against a budget target
- Flag anything that moved more than a small, defined threshold for a closer look, rather than reviewing every line every month
What monthly tracking catches that annual review misses
A subscription price increase, a forgotten unused tool still being paid for, or a vendor cost creeping up gradually are all things that are cheap to catch monthly and expensive to discover a year later, after twelve months of accumulated overpayment.
Keeping it sustainable
A tracking process too detailed to maintain consistently gets abandoned after a few months — a simple, consistent monthly categorization beats a more thorough process that only gets done sporadically.
