Why Interior Contractors Run Out of Cash.

QUICK ANSWER

Commercial interior contractors doing tenant improvements, millwork, and specialty finishes lose cash to three structural problems: no per-work-type job costing so profitable scopes subsidize losing ones, GC and landlord billing cutoffs that slide draws 30 days when missed, and TI schedules that move constantly delaying billing milestones while costs keep running. On a $2M interior contractor doing TI work, $250K--$400K of earned revenue can be in the pipeline at any given time.

Interior contracting -- millwork, cabinetry, specialty finishes, interior fit-out, and custom built-ins for commercial spaces -- has a financial structure that generic bookkeeping handles poorly. Work types within a single job have completely different labor and material ratios. A millwork package has high material cost and moderate labor. Specialty finishes have high labor and low material. When both run in one cost bucket, neither is managed correctly and the estimating never improves.

THE FAILURE MODE

Why Interior Cash Disappears

01

No Per-Work-Type Job Costing

Millwork, specialty finishes, built-ins, and TI packages all have different labor-to-material ratios. Tracking them in one bucket means profitable work types subsidize losing ones and estimating never corrects. A $2M interior contractor can have one scope making 35% gross margin and another at 8% -- and see 22% blended without knowing which is which.

02

TI Schedule Delays Billing Milestones

Tenant improvement schedules are among the most volatile in commercial construction. Landlord delays, permit holds, prior tenant vacate issues -- all push the milestone that triggers your billing. Costs keep running. CFOS structures the SOV with mobilization and material procurement as front-loaded line items that do not depend on completion milestones.

03

Multi-Party Billing Approvals

TI work often requires approval from the tenant, the landlord, and sometimes a property manager before the GC pays. Each layer adds review time. Miss the cutoff for any one of them and the draw slides 30 days. CFOS tracks every approval layer for every active TI project.
