CASE STUDY · FIBER CONTRACTOR

THE BANK ACCOUNT MADE NO SENSE.

QUICK ANSWER

A $2.3M fiber splicing subcontractor had skilled crews, major telecom carrier clients, and a bank account nobody could explain. Some months looked strong, some looked like a disaster, and none of it was predictable. Project costs were posting to the wrong places, so the real picture was invisible. January 2026 ran $141,000 of project cost against $144,000 of revenue, which leaves almost nothing before overhead. The owner now reads his own numbers every month and knows what his T&M rate has to be.

Time and material fiber work comes in bursts. A carrier releases a batch of splicing, the crews run hard, then the schedule thins out and overhead keeps running at the rate it ran during the busy stretch. The rates being charged had been built on busy month assumptions rather than honest utilization across a full year, so the price was right for the best month and wrong for the year. His wife was keeping the books after hours, and none of this was carelessness: subcontractor accounting is genuinely complex, and a cost coded to the wrong place is invisible by definition. This study has no dollar recovery figure attached to it. The outcome is that the owner can see the business, which is what every dollar figure on the other studies started as.

THE SITUATION

A $2.3M FIBER SUB. AND A BANK ACCOUNT NOBODY COULD EXPLAIN.

A fiber splicing subcontractor doing $2.3M a year, working time and material for major telecom carriers. The crews were skilled and the client list was the kind most subs would want. Some months the bank account looked great, some months it was a disaster, and nobody could say in advance which of the two was coming.

THE PROBLEM

THE BANK ACCOUNT MADE NO SENSE.

The revenue was there. The work was there. The account balance had no relationship to either one that the owner could describe out loud. A good month and a bad month didn't look different enough going in to explain how different they looked coming out.

His wife was keeping the books after hours, and the problem was never care. Subcontractor accounting is genuinely complex: job cost coding, work in progress, and material against labor on time and material tickets. Project costs were posting to the wrong places, and a cost in the wrong place doesn't tell anybody it's in the wrong place.

So the real picture was invisible. Pricing came from memory of how the busy months felt, and nobody could say which months made money and which ones consumed what the good months earned.

WHAT WAS REALLY WRONG

PRICED FOR THE BUSY MONTH, PAID FOR THE WHOLE YEAR.

Time and material fiber work comes in bursts and overhead doesn't stop between jobs. That's the whole mechanism. A month with a full schedule absorbs overhead comfortably, a month with a thin schedule absorbs none of it, and the year is the average of the two rather than the good one repeated twelve times.

The rates being charged had been built on busy month assumptions rather than honest utilization across a full year, so they recovered overhead only in the months that were already working. January 2026 is the clearest read on the file: $141,000 of project costs against $144,000 of revenue, which leaves almost nothing before overhead is paid.

The Job Profitability System was the system that wasn't running. Project costs were posting where they didn't belong, so no job and no month could be read against what it had been priced at, and a billing rate can't be corrected out of a total that mixes everything together.

Job Profitability System
THE INTERVENTION

WHAT CHANGED, WEEK BY WEEK.

Week 1: Took the books off after hours work and started a monthly close, so a month could be read while it was still recent enough to do something about.
Weeks 2 to 4: Corrected the job cost coding so project costs posted against the job and the month that consumed them instead of wherever they had been going.
Month 2: Read the months separately rather than as a total, which produced the January 2026 diagnostic: $141,000 of project cost against $144,000 of revenue.
Months 2 to 3: Rebuilt the T&M rate against utilization across a full year rather than a busy month, and set the monthly review where the owner reads his own numbers.

This study has no dollar recovery figure, and inventing one would be the easiest thing on this page to do. What changed is what the owner can see. He reads his numbers every month, he knows which months are structurally profitable and which ones consume margin, and he knows what his T&M rate has to be. He is building out structured cabling work, which is contracted and bills predictably, to stabilise revenue alongside the time and material. Decisions now come from what the business is doing and not from what it feels like it's doing.

Total time from first call to a monthly close the owner reads himself: the standard 60 day onboarding. There's no debt payoff date to report on this engagement, because the outcome here is visibility and a corrected pricing basis rather than a recovery.

WHAT THIS MEANS FOR OTHER CONTRACTORS

DOES THIS SOUND FAMILIAR?

This applies to any contractor whose work comes in bursts. Time and material splicing, service calls, storm response, and on call maintenance all share it: somebody else's release schedule sets the month, overhead runs at the same rate whether the crews are out or not, and the rate on the ticket was set during a stretch that felt busy.

The signal is a bank account that doesn't track with how the work felt. If a strong month and a weak month produce the same balance, or the opposite of what you expected, the costs aren't posting where the work happened, and every price built on top of that's a guess. The second signal is a spouse keeping the books at night, because subcontractor accounting needs somebody whose whole job it is.

The figures on this page came from this client's own books rather than a survey or an estimate, and no client is identified anywhere on this site. The carriers, the markets, and the projects stay out too, because any two of those would identify a company in a regional trade.

COMMON QUESTIONS

FREQUENTLY ASKED.

Because project costs were posting to the wrong places, so no month could be read against what it had been priced at. Time and material fiber work comes in bursts while overhead runs straight through the quiet stretches, and the T&M rates had been built on busy month assumptions rather than utilization across a full year. January 2026 ran $141,000 of project cost against $144,000 of revenue, which leaves almost nothing before overhead is paid.
Because there isn't a verified one, and we won't publish a number this client's books don't support. The outcome here is visibility and a corrected pricing basis: the owner reads his financials every month, knows which months are structurally profitable and which ones consume margin, knows what his T&M rate has to be, and is building out contracted structured cabling work to stabilise revenue alongside the time and material. Every dollar outcome on the other studies on this site started at this same point.
Yes, for fiber, splicing and low voltage subcontractors roughly between $1M and $12M doing time and material work for carriers. The sequence is the same every time: correct the cost coding first, close the books monthly so a month can be read while it's recent, then rebuild the billing rate on utilization across a full year and not on the best month. Adding a contracted work type on top of the T&M is what makes revenue predictable, and it only pays once the rate underneath it's right.
