Why Door & Hardware Contractors Float the Hardware Order

QUICK ANSWER

Door and hardware contractors float the order when hollow metal frames and hardware sets get bought months before installation billing catches up, deliveries slip while billing waits on them, and out-of-sequence installs burn extra trips nobody prices. CONTROL bills stored material, documents the delays, and codes every remobilization.

THE CASH PROBLEMS

The specific ways door & hardware contractors lose cash, pulled straight from what makes this trade different.

Procurement Float on Frames and Sets

Hollow metal, wood doors, and hardware sets are bought early and stored long. Stored material billing puts that six-figure float on the project.

Delayed Delivery Billing

When a manufacturer slips, your billing slips with it unless the contract says otherwise. Delivery milestones with dates keep the pay application moving.

Installation Sequence Holes

Frames set early, doors hang late, and hardware finishes last. Sequence-split billing keeps each visit funded instead of waiting on final completion.

QUESTIONS DOOR & HARDWARE CONTRACTORS ASK
Why do door and hardware contractors run out of cash?
Door and hardware contractors run out of cash because the trade is mostly procurement: frames, doors, and hardware sets bought months before installation while billing waits on field progress. When a manufacturer slips, the float stretches further. Stored material applications the month goods are received close most of the hole.
How should a door and hardware contractor bill the work?
A door and hardware contractor should split the schedule of values by visit: frames set, doors hung, hardware installed, with stored material lines for purchased goods. Chapter 6 of CONTROL structures that SOV, so each mobilization funds itself instead of the whole contract waiting for the last lockset.
What profit margin should a door and hardware contractor target?
A door and hardware contractor should target 22 to 30% gross profit per project and 12% net profit after all expenses, with overhead between 9 and 13%. Out-of-sequence trips are the margin leak to watch, so every extra mobilization deserves a cost code and, where the cause is someone else's schedule, a change order.
