Reading a profit-leak report: what it can and can’t tell you

How to read a profit-leak report for a small service business: what a finding means, how to check it, and the limits of benchmark comparisons.

A profit-leak report compares how your business says it operates with outside reference points, and flags areas where margin may be slipping. Used well, it tells you where to look first. It doesn’t tell you what is definitely wrong.

What a finding means

A finding such as “unbilled time on service calls” means your answers point to a common pattern. It is a hypothesis to check against your own records, not a diagnosis.

How to check a finding

  1. Pull the records it refers to: for unbilled time, a month of job tickets.
  2. Compare quoted time with actual time on ten jobs.
  3. Decide if the gap is real and worth fixing.

The limits of benchmarks

  • Public industry figures are averages across many businesses and years. Your market, mix and size may differ.
  • A gap from an average is not automatically a problem; it may be a deliberate choice.
  • Good reports name the source for every comparison so you can judge it yourself.
Example · fictional, illustrative numbersExample Plumbing (fictional) reports 30% gross margin on replacement jobs. A report compares that with an illustrative range and flags it. The owner checks ten recent quotes and finds most were discounted after the first visit. That is the leak; the benchmark only pointed to it.

What a report is not

A profit-leak report is not an audit, accounting review, or financial, tax or legal advice. Talk to your accountant before acting on anything that affects your books or taxes.

The Guideily Profit Report follows this approach, starting at $49.
