You bankroll the mill six months before you get paid
The mill wants a check before it ships, the GC won't pay for stored material, and your cash sits in a warehouse for four months waiting on a space that isn't ready.
Most subs buy material roughly in step with the work, so cash out and cash in are weeks apart. Flooring buys the single largest cost on the job up front, because a dye lot can't be reordered in pieces, and then waits for the last finish slot in a 20 month schedule. You're running a financing operation at zero markup, and it scales with the size of the package you just won.
The size of it
Cash goes out in month one, install happens in month four, the invoice goes in at month four, pay-when-paid pushes payment to month six, and retention releases around month twelve. The biggest line on the job rides on your balance sheet for half a year.
One school or hospital package is $200k to $400k of goods against a distributor credit line that's realistically $50k to $100k, so the balance goes COD or deposit. The material then gets produced, delivered, and warehoused weeks before anybody lets you into the space. Billing it as stored material on the G703 takes a bill of sale, an insurance certificate that lists the owner, and written off site storage approval, and plenty of GCs refuse a stored material line item outright no matter what you send them. Attic stock required by spec comes off the same dye lot, sits in your building all year, and gets delivered at closeout, frequently with no pay line of its own.
Three moves, in order
Step 07: Monthly cadence
Weekly bookkeeping, cost to complete, and one CEO report, on the same days every month.

What flooring owners ask
GC won't pay for stored flooring material and the mill wants a deposit?
The mill wants a check before it ships, the GC won't pay for stored material, and your cash sits in a warehouse for four months waiting on a space that isn't ready.
What does it cost?
Cash goes out in month one, install happens in month four, the invoice goes in at month four, pay-when-paid pushes payment to month six, and retention releases around month twelve. The biggest line on the job rides on your balance sheet for half a year.
What do I do first?
Add up every open job where material is bought and not yet billed, and set that number next to your line of credit balance. That's what the schedule is costing you right now.
What are flooring contractors supposed to be making?
Flooring runs 19% gross margin, 14% overhead and 5% net profit before taxes at $1M–$5M. The all-trade average is 7%, so this trade sits 2 points below 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.
Josh Luebker ran commercial construction projects before he ran the numbers behind them, on data centres, military bases, hospitals, and high-rises. He wrote CONTROL: The Construction Financial Operating System, which is an eight-step framework for commercial subcontractors, and it publishes on October 1, 2026. He is a master electrician who moved into the office and kept the field vocabulary.

Where a figure changes between editions, the older edition keeps its year in the title so a citation to it stays correct.
