If you run a high-ticket service business with 5 to 15 employees — managing projects in the $20,000 to $200,000 range — and you have ever looked at your end-of-job margin and wondered where it went, this article is written for you.
Derek owns a commercial landscaping operation with eleven employees in the greater Atlanta area. Average contract value: $35,000. Average project duration: six to eight weeks. He has run this business for nine years and considers himself meticulous about estimating. He prices material, labor hours, equipment time, and subcontractors with care. When I asked him to track crew time for a full month — not time on client properties, but all time the crew was on the clock — he found something he had never calculated.
His four-person crew was logging an average of forty-one paid hours per week each. Thirty-one of those hours were on client sites, performing billable work. The other ten hours disappeared across three categories he had never priced for.
Those ten hours were not waste. They were not inefficiency. They were the operating reality of running a field team — three categories of necessary, unavoidable, and consistently unpriced labor.
The first crew member arrives at the shop at 7:00 a.m. The first client site is twenty-two minutes away. The second site is eighteen minutes from the first. At the end of the day, the crew returns to the shop — another twenty minutes. That is approximately sixty minutes per crew member per day in transit.
Sixty minutes per person, per day, at an average wage of $24 an hour, across a crew of four: $96 in daily transit cost. Five days per week: $480. Across forty-eight working weeks: $23,040 in drive time cost per year — for a single four-person crew.
None of that went into Derek's estimates. He priced the hours he expected the crew to spend on site. He did not price the hours between the shop, the properties, and the return.
Drive time is the most consistent non-billable cost in any field service business. For commercial landscaping, HVAC, facilities management, or bespoke installation work, the daily transit gap between paid hours and productive hours runs between eight and fifteen percent of total payroll. It is mandatory. It is predictable. And it is almost never in the labor line of any estimate.
The second category is harder to see because it does not have a clean name. Derek calls it “the back-and-forth.” On one day I asked him to track in detail, his foreman had made three stops before noon: a supply run to pick up a replacement part that arrived damaged in the original delivery, a drop at the disposal site for green waste from the previous day's work, and a loop back to the shop to swap out a piece of equipment that had developed a problem overnight.
Three trips. Four hours total across two crew members. Zero billable output.
Logistics runs — material pickups, delivery corrections, waste disposal, equipment swaps, supply chain gaps — average between 1.5 and 3 hours per field employee per week in most service operations with an active field component. Some weeks are zero. Some weeks are six. The average across a month is rarely zero.
At $24 per hour and two hours per week per employee: $48 per employee per week. Across four crew members: $192 per week. Across forty-eight working weeks: $9,216 per year — not in a single estimate Derek had ever submitted.
The logistics run category is the one business owners most often attribute to “just how the business works.” That attribution is accurate. It is part of how the business works — which is exactly why it belongs in the cost structure.
The third category is the one that most visibly erodes margin, and the one most service business owners actively resist pricing for.
Derek's crew completed a $42,000 commercial property enhancement in March. Six weeks after project close, the client called: a drainage issue had caused erosion in one section of the new planting area. Two crew members, one full day, $192 in direct labor. No invoice. No change order. No dispute — the work was within the warranty period, the issue was real, and Derek handled it professionally.
That is the correct response. It is also a cost.
Most high-ticket service businesses with a field installation or service component carry implicit warranty obligations — not always written, often assumed, almost never priced. A warranty callback on a completed job costs between four and twelve hours of direct labor depending on scope, plus any materials required. For a business running twelve to fifteen projects per year, two to four callbacks is a predictable number. At four hours per callback and $24 per hour per crew member: $192 per callback. Three per year: $576. Not a catastrophic number on its own — but the more important point is that this cost exists on every project's ledger and appears in the estimate of almost none.
| Category | Weekly hrs / employee | Weekly cost (4 crew) | Annual cost |
|---|---|---|---|
| Drive time | 5.0 hrs | $480 | $23,040 |
| Logistics runs | 2.0 hrs | $192 | $9,216 |
| Warranty callbacks | ~0.25 hrs/week avg | $24 | $1,152 |
| Total | ~7.25 hrs/week | $696 | $33,408 |
Thirty-three thousand dollars in annual labor not attributable to any single error. Not a lost bid, not a bad hire, not a project that went sideways. Three ordinary categories of operational reality — each showing up on every job, each priced at zero in the estimate.
This is the mechanism behind the non-billable time adjustment in a fully burdened labor rate. As we covered in what Marcus's $28 wage actually costs your business per productive hour, when a field service business operates at a twenty percent non-billable ratio, these three categories are almost always the primary drivers. Drive time is the largest. Logistics runs are the most variable. Warranty callbacks are the most often ignored.
The fix requires two things: knowing the numbers, and putting them in the estimate.
Step one is four weeks of honest time tracking across every crew member — not time on site, but total time on the clock. The difference between those two numbers is your non-billable ratio. Broken by category, it shows exactly which of the three types is consuming the most hours.
Step two is a non-billable adjustment in your labor rate. If your crew runs at a twenty-two percent non-billable ratio, divide total weekly labor cost by the percentage of hours that are actually billable. A crew member paid $24 an hour for forty hours per week, with thirty-one productive hours, costs $24 × 40 ÷ 31 = $30.97 per productive hour before adding any other burden layer. That is the number that belongs in the estimate — not the offer-letter wage.
| Labor cost basis | Hours × rate | Total in estimate | Actual cost | Unrecovered gap |
|---|---|---|---|---|
| Wage only ($24/hr) | 200 hrs × $24 | $4,800 | $6,194* | $1,394 |
| True productive-hour rate ($30.97/hr) | 200 hrs × $30.97 | $6,194 | $6,194 | $0 |
*Actual cost = 200 billable hrs ÷ 78% billable ratio × $24 = $6,154, rounded to reflect the full annual non-billable average.
The estimates submitted with the wage produce a margin projection. The invoices paid reflect the actual cost. The gap between those two lines is not a bad week — it is a structural pricing error repeated on every job in the pipeline.
The System That Tracks the Gap
TIM is Digital Labor — a business operating system for US service businesses with 1 to 15 employees running high-ticket projects. TIM handles lead follow-ups, professional quotes, project tracking, payment requests, and client communication — the work that keeps businesses from growing.
The Operations Manager tracks actual crew time by category — site hours, transit, logistics, and callbacks — so the non-billable ratio is a calculated number updated in real time, not an annual guess. When a warranty callback is logged, it posts against the completed job record so the true final cost of that project updates automatically. When a logistics run is recorded, it feeds the weekly non-billable tally that calibrates the labor rate for the next estimate cycle.
The average office and administrative support role costs $4,000 to $4,500 per month in salary alone, according to the Bureau of Labor Statistics. The time tracking, cost attribution, and labor rate calibration that TIM executes across every active project converts a non-billable cost problem from a guessing exercise into a measurable, priced, recoverable line item.
