VISIBILITY INTO
A BUSINESS THAT
FELT RANDOM.
The owner of a $2.4M fiber splicing subcontracting company was working hard. Skilled crews. Major telecom carrier clients. The bank account did not make sense. Some months looked great. Some months were a disaster. No rhythm, no predictability. When we cleaned up the books, the volatility had a name. T&M (time and materials) fiber work comes in bursts. Overhead does not stop between jobs. The rates being charged were built on busy-month assumptions. Not honest utilization across a full year. In January 2026 alone: $141K in project costs against $144K in revenue. Almost nothing left before overhead hit.
T&M work is not progress-billed construction. The cash flow behavior is fundamentally different. Most financial systems are built for progress billing and break down when applied to fiber, telecom, low voltage, and other T&M-heavy trades.
Revenue Came in Bursts
T&M fiber work is dispatched as needed. Some months, every tech is booked. Some months, the phones barely ring. Revenue swings wildly with no visible reason.
Overhead Did Not Stop
Trucks. Equipment. Insurance. Tools. The office. All those costs continued whether crews were dispatched or not. Slow months silently bled margin.
T&M Rates Were Set on Busy-Month Math
The hourly rates being charged assumed productive utilization. The reality across a full year was very different. The rates looked profitable in busy months and lost money in slow ones. Nobody could see that without per-month analysis.
Costs Had No Home
The owner's wife was handling the books after hours. Not out of carelessness. Subcontractor accounting is genuinely complex. Without job costing structure, costs were getting recorded but not categorized in ways that let anyone see what was really happening.
Once the books were cleaned up and properly structured, January 2026 alone showed the problem clearly. $141K in project costs against $144K in revenue. Three thousand dollars of gross margin before any overhead expense. Not after. Before. There was almost nothing left to absorb the rent, insurance, equipment, and other costs that hit the business regardless of how many techs were billable that month.
This was not a one-month anomaly. It was the underlying math the business had been running on for years. Busy months covered for slow months. The average looked acceptable. The owner had been working below market on his own compensation and deferring everything that could be deferred. The business was not profitable. It was being subsidized by the owner.
- Job costing structure: 7-category framework with cost codes specific to T&M work. Labor (by type), travel, materials, equipment. CONTROL Chapter 1.
- Realistic utilization analysis: calculated billable hours across a full year. Accounting for slow periods, training, weather, equipment downtime. Not the busy-month assumption.
- T&M rate recalculation: new bid rates built on realistic utilization that truly recover cost across the full year. Not just productive months.
- Monthly visibility: monthly P&L showing structurally profitable months vs margin-consuming months. The owner finally sees what is happening. CONTROL Chapter 7.
- Diversification strategy: structured cabling work (contracted, often progress-billed) brought in alongside the T&M work to stabilize revenue across the year.
The owner now sees his numbers every month. He knows which months are structurally profitable and which ones consume margin. He knows what his T&M rate really needs to be. He is in active conversations with carrier clients to bring his rates in line with reality.
He is actively building out structured cabling work. Contracted. Predictable billing. To stabilize revenue alongside the T&M work. The crews are the same. The skill set is the same. What is changing is the revenue mix and the pricing discipline.
For the first time, he is making decisions based on what the business is truly doing, not what it feels like it is doing. That alone is the difference between a business that runs the owner and a business the owner can finally run.
WANT IT INSTALLED FOR YOU?
CONTROL teaches you how to build the system yourself. The Construction CFO, a service of Sulphur Prairie Management, builds and runs it for you. Same system. Same outcomes. From $1,900 per month. 60-day onboarding.
T&M (time and materials) revenue comes in bursts. When there is work, the contractor is busy and revenue is high. When there is not, the equipment, vehicles, and overhead still cost money but no revenue is coming in. If T&M rates are priced for busy months, the slow months silently bleed margin. Most T&M contractors price for what feels like average utilization, not what happens across a full year.
Fiber splicing, and most fiber, telecom, low voltage, and AV work, runs on T&M contracts rather than progress-billed lump sum work. Revenue happens when techs are dispatched. There is no SOV. No monthly pay app. No AIA billing. The cash flow behavior is fundamentally different. Most generic financial systems do not handle it well.
Reverse from total annual cost. Add up all the costs that have to be recovered. Labor. Fully-loaded burden. Vehicle and equipment costs. Tools. Overhead. Then divide by realistic billable hours across a full year, not theoretical billable hours. The result is the minimum T&M rate that recovers cost. Add target margin on top to get the bid rate.
Diversification of revenue types. T&M alone creates feast-or-famine cash flow. Structured cabling (contracted, often progress-billed) creates predictable monthly revenue. The combination smooths out the volatility. Busy T&M months and slow ones are balanced by consistent cabling revenue. Same crews. The business stops feeling random.
Yes, when they understand the model. Most CFOs only work with progress-billed contractors and apply that lens to T&M businesses. It does not work. T&M requires utilization-based rate setting, monthly revenue trend analysis, and cash flow forecasting that accounts for natural revenue variability. Sulphur Prairie Management handles T&M-heavy contractors as a specialty.
