This is a study about reporting, not performance. Nobody changed how they ran their business between the two sets of numbers. What changed is what those numbers were able to tell them.
A chart of accounts is the list of categories your bookkeeping sorts every dollar into. For a service business, the split that matters most is cost of service, what it costs to actually do the work, against operating expense, what it costs to keep the doors open. Get that split wrong and your gross margin is wrong.
Most service business owners never picked their own chart of accounts. A bookkeeper set one up years ago, a CPA added a few lines, a CRM dropped in some defaults, and nobody has touched it since. Nobody did that on purpose. It just never got standardized against anything.
We took 107 service business operators, roughly $230 million in combined annual revenue, and ran their financials twice over the same period.
The first pass used the books as we found them. Whatever chart of accounts their old bookkeeper set up, their CPA added to, or their CRM dropped in by default. The second pass used one standardized FRAXN chart of accounts.
Same operators. Same months. Same dollars. The only variable was how those dollars were sorted. That design matters, because it means nothing here can be explained away by a good year or a bad one. Every difference below is a difference in reporting, not in the business.
| Measure | Before standardizing | After standardizing |
|---|---|---|
| Total revenue reported | $229.77M | $229.86M |
| Cost of service, share of total cost | 22.9% | 47.5% |
| Operating expense, share of total cost | 77.1% | 52.5% |
| Median absolute gross margin shift | 18.0 percentage points | |
| Median absolute EBITDA margin shift | 1.2 percentage points | |
No. 104 of the 107 operators reconciled near exactly on revenue. Across 107 service business operators representing about $230 million in combined annual revenue, total reported revenue moved from $229.77 million to $229.86 million, a variance of $87,010, or 97.2% dead on.
Nothing was inflated. Nothing was invented. Every dollar that went in came back out. What moved was where those dollars were filed.
Before standardization, the median operator was booking 77.1% of total spend as operating expense. Getting there starts with how to group revenue lines, and for one trade in particular, bookkeeping for pest control companies. After standardization, that figure was 52.5%. Median cost of service moved the other way, from 22.9% of total cost to 47.5%.
In plain terms, the median operator was calling roughly 77 cents of every dollar overhead. Rent, insurance, admin, the things that do not move when you run another truck. Closer to half of that turned out to be cost of service, the things that climb on every single job.
The spread tightened hard too. The middle 50% of operators went from a cost of service range of 6.7% to 42.0%, down to a range of 39.4% to 54.5%. Before the exercise, no two operators were really measuring the same thing.
Across 107 service business operators representing about $230 million in combined annual revenue, the median operator saw reported gross margin shift 18.0 percentage points once their books were moved onto a standardized chart of accounts. The middle 50% moved between 2.0 and 33.9 points.
Same business. Same dollars. A completely different answer to the question of what it costs to do the work.
The median absolute operating expense shift was 15.2 percentage points, with the middle 50% falling between 4.2 and 34.6 points. Gross margin and cost of service are two views of the same reclassification, so this finding and the one above describe the same money from opposite ends.
The largest reclassification landed in the $1M to $3M revenue tier, with a median operating expense shift of 21.0 points. Above $3M it was 12.7 points. Gross margin shifts ran roughly 20 points under $3M against 12.2 points above it.
That is not a knock on smaller operators. Bigger businesses simply tend to arrive with more developed accounting already behind them. Everybody starts somewhere.
No. The median absolute EBITDA margin shift was 1.2 percentage points. Standardizing the books did not change what these businesses earned. It changed what their owners could see.
It could not have worked any other way. It is the same money either way. If the bottom line had jumped, that would be a reason to distrust the exercise, not a reason to celebrate it.
The study says it plainly in its own conclusion. Standardization did not change business performance. It changed the visibility, consistency, and comparability of the financial information used to evaluate that performance.
Worth saying just as plainly: none of these operators were doing anything wrong. Nobody was hiding money and nobody was cooking anything. They were running honest businesses on bookkeeping conventions that had simply never been standardized against anything. Inconsistent is not the same as dishonest.
But you cannot price a job, hire ahead of demand, or tell which route actually makes money when your cost of service number is off by 18 points. Most operators have never seen that number stated correctly. That is the problem worth fixing.
Pest control operators can also compare their own numbers against the Pest Control Financial Performance Benchmark, a separate study of 125 operators.
A chart of accounts is the list of categories your bookkeeping sorts every dollar into. Materials, labor, insurance, marketing, rent. Every transaction lands in one of those buckets, and the buckets are what build your financial statements. Get the list right and your numbers mean something.
Cost of service is what it costs to actually do the work: field labor, materials, vehicle costs, anything that climbs when you run another job. Operating expense is what it costs to keep the doors open: rent, insurance, office admin. Your gross margin depends entirely on where you draw that line.
No. In this study of 107 operators, the median absolute EBITDA margin shift was 1.2 percentage points. Standardizing the books does not change what a business earns. It changes what the owner can see, which is where the value actually is.
A good first test: what share of your total spend is booked as overhead? In this study the median operator was calling 77.1% of spend operating expense before standardizing, and 52.5% after. If your overhead number looks that high, your gross margin is probably wrong.
Without one you cannot compare this month to last month, your business to a peer, or your gut instinct to the math. Half the operators in this study had a reported gross margin off by 18 points or more, purely because nobody had ever standardized how their costs were sorted.
Book a walkthrough. We will go through your numbers with you and show you what changes when the accounts are structured to tell the truth.
