WHY FIBER CONTRACTORS LOSE MARGIN WITHOUT KNOWING IT.

QUICK ANSWER

Fiber margin is lost to three specific things: the carrier's calendar, the pole owner's price, and the paperwork mile. Fiber subcontractors at $1M to $5M run 18 percent gross and 6 percent net, against CFOS targets at $1M to $5M of 24 percent gross and 10 percent net. All three are measurable, and all three are invisible without job costing that reads against the estimate.

Fiber contractors at $1M to $5M net 6 percent, rising to 8.5 percent by $25M to $50M; the CFOS target at $1M to $5M is 10 percent. The distance between the trade average and the CFOS target isn't a pricing problem in this trade. It sits in the three mechanisms below, each of which moves margin without appearing as a failure on any single job. Unit-price MSAs pay per foot and per splice on the carrier's terms, gated by closeout documentation. Crews get paid Friday; the carrier pays when the audit clears. The gap is where fiber contractors meet factoring salesmen.

THE THREE BIG LEAKS

THE MATH BEHIND THE MISSING CASH.

LEAK 01

The Carrier's Calendar

Unit-price MSAs pay per foot and per splice on the carrier's terms, gated by closeout documentation. Crews get paid Friday; the carrier pays when the audit clears. The gap is where fiber contractors meet factoring salesmen.

LEAK 02

The Pole Owner's Price

Make-ready costs are set, scheduled, and invoiced by the utility that owns the pole, and one industry director puts the five-year increase near 300 percent. A pass-through that triples without its own variance report is a margin event nobody has priced.

LEAK 03

The Paperwork Mile

As-builts, GIS packages, and compliance documentation gate every dollar of BEAD and carrier money. Production that outruns documentation is unbillable inventory lying in the ground. (cfos-cash-flow-cycle-system) ---

The carrier's terms (unit-price work on someone else's clock)
Make-ready (the cost that tripled)
BEAD (the wave that keeps rescheduling)

Industry figures are Fiber contractors' AVERAGE for each revenue band, not a floor. The CFOS net profit target is set at 10 percent before taxes or 3.5 points better than your trade's average at your revenue, whichever is higher, and the gross margin target is set at whatever gross margin produces that net profit once your overhead is paid, and never below your trade's own average. Gross minus overhead equals net on every column, so the rows tie out.

Range reflects the three tiers below. Which one you're in depends on how much of the work you want off your desk. No payroll. No hidden line items.

Core

You stop guessing.

You get the CFO work. Job costing built against the way you estimate, a 13 week cash forecast, monthly WIP, and a meeting every month that ends in decisions rather than a report.

Your bookkeeper keeps doing the books.

Executive

You stop touching the books.

Everything in Core, and we run the bookkeeping and the controllership as well. Nobody in your office is answering coding questions or chasing a reconciliation at month end.

We do the books. No payroll.

Strategic

Every job shows its margin while it's still running.

Everything in Executive, plus the job costing and WIP platform set up, loaded with your cost codes, and managed for you every month. You never have to learn it.

We do the job costing.

COMMON QUESTIONS

FREQUENTLY ASKED.

Fiber contractors at $1M to $5M net 6 percent on average, rising to 8.5 percent by $25M to $50M; the CFOS target at $1M to $5M is 10 percent. The margin leaks in this trade are cash-timing leaks: carrier terms, make-ready pass-throughs, and documentation-gated payments. Every net profit figure here is stated before taxes, the same basis CFMA reports on, so the two are directly comparable.
Because carrier MSAs pay per unit on the carrier's calendar, gated by closeout audits, while crews and boring subs get paid weekly. Factoring converts that timing gap into a permanent margin tax. The verified alternative: documentation-complete billing, closeout packages built daily, and a 13-week cash forecast that prices the carrier's terms into every bid.
Make-ready is the pole owner's work (moving existing attachments, replacing poles) required before fiber can attach, priced and scheduled by the utility and paid up front by the builder. Industry reporting puts the five-year cost increase near 300 percent. Track it as its own pass-through with a variance report; it's the least controllable and most inflationary line in aerial construction.
It's real money arriving on a compliance schedule: Davis-Bacon payroll, insurance packages with 24-to-48-hour COI correction windows, GIS-format as-builts, and engineering timelines that punish late starts. Price the compliance load and the mobilization float before bidding; the contractors winning BEAD subcontracts staffed the paperwork before the first strand went up.
Documentation-complete: the invoice goes out when the as-built package, photos, and test results are audit-ready, not when the crew moves on. Every unit billed without its closeout package is a receivable waiting to be disputed. Daily as-built discipline is the collection strategy.
A bookkeeper records history. Carrier-term cash modeling, make-ready variance tracking, BEAD compliance costing, and documentation-gated billing are a control system, which is CFO work. SPM operates that financial control function for fiber contractors. ---
