Retainage releases per work order, and you're third in line

Your money is sitting behind a carrier, a turf vendor, and a QC desk, released a few thousand at a time on work orders you finished last year.

WHY IT IS A FIBER PROBLEM

Most subs carry one retainage balance per project and can quote it off the top of their head. You carry retainage on hundreds of individual work orders, released one at a time by a QC desk two companies removed from you. Nobody in the office tracks it at that grain, so it ages out of view a few thousand dollars at a time until the total reaches six figures.

WHAT IT COSTS

The size of it

Sixty to a hundred twenty day collection cycles run against a business whose largest cost is weekly field payroll. Retainage becomes a receivable nobody tracks by work order, and real money disappears from the conversation.

OVERHEAD AT $1M–$5M
15%
CFOS target 14% for fiber.
GROSS MARGIN AT $1M–$5M
22%
CFOS target 24% for fiber.
NET PROFIT AT $1M–$5M
7%
CFOS target 10% for fiber.

The chain runs carrier to turf vendor to local sub to splice sub, and you're somewhere in the middle of it. Each layer holds five to ten percent retainage and each layer's terms are pay-when-paid, so your DSO is the sum of everyone above you, not the terms printed on your own contract. Retainage releases at final acceptance of the as-built package per work order, which means the same paperwork that delays the invoice delays the retainage sitting behind it. On grant-funded builds the hold runs to the end of a two or three year program even though your boring wrapped up in month three.

WHAT TO DO

Three moves, in order

STEP 01
Build a retainage schedule keyed to work order with the acceptance date, the release trigger, and the layer of the chain holding it.
STEP 02
Ask the turf vendor monthly, in writing, for their aging of your accepted work orders and reconcile it line by line to yours.
STEP 03
On grant-funded routes, price the long hold into the rate before you sign and carry that retainage separately so it never gets counted as collectible in ninety days.
QUESTIONS

What fiber owners ask

Tracking retainage by work order on turf vendor work?

Your money is sitting behind a carrier, a turf vendor, and a QC desk, released a few thousand at a time on work orders you finished last year.

What does it cost?

Sixty to a hundred twenty day collection cycles run against a business whose largest cost is weekly field payroll. Retainage becomes a receivable nobody tracks by work order, and real money disappears from the conversation.

What do I do first?

Build a retainage schedule keyed to work order with the acceptance date, the release trigger, and the layer of the chain holding it.

What are fiber contractors supposed to be making?

Fiber runs 22% gross margin, 15% overhead and 7% net profit before taxes at $1M–$5M. The all-trade average is 7%, so this trade sits right on it. The CFOS target is 10%.

Which part of the system fixes it?

The step is number 07, monthly cadence. Weekly bookkeeping, cost to complete, and one CEO report, on the same days every month. It comes from chapter 7 of CONTROL: The Construction Financial Operating System.
