ONE PROBLEM, IN DETAIL

INTERIOR: THE TI FLOAT

QUICK ANSWER

Tenant-improvement work runs on allowances ($15 to $80 per square foot by market and asset class) that reimburse AFTER the work: the contractor gets paid by a tenant who gets paid by a landlord only on a clean draw package (paid invoices, lien waivers, proof of completion), typically 30 to 60 days after submission, and some deals hold the entire allowance until certificate of occupancy.

WHAT BREAKS

WHERE THE MONEY GOES.

The TI float (financing the landlord's building)

Tenant-improvement work runs on allowances ($15 to $80 per square foot by market and asset class) that reimburse AFTER the work: the contractor gets paid by a tenant who gets paid by a landlord only on a clean draw package (paid invoices, lien waivers, proof of completion), typically 30 to 60 days after submission, and some deals hold the entire allowance until certificate of occupancy. The published tenant-side advice says it plainly: "you need working capital to float construction, which catches a lot of first-time tenants by surprise." It catches their contractors harder.

WHAT THIS TRADE SHOULD EARN

THE NUMBER TO MEASURE IT AGAINST.

Interior contractors run about % net profit at $1M to $5M, rising to roughly 9% at $5M to $10M. The CFOS target at $1M to $5M is10%, set at 10 percent before taxes or 3.5 points better than your trade's average at your revenue, whichever is higher. A problem like this one lives in the distance between those two figures rather than in a loss on any single job.

Gross margin over the same bands runs % to 21%, against a CFOS target of 10%.

COMMON QUESTIONS

FREQUENTLY ASKED.

Landlord to tenant to contractor, backward from the work: the contractor bills the tenant, the tenant submits a draw package (paid invoices, lien waivers, completion proof) to the landlord, and reimbursement lands 30 to 60 days later, or at certificate of occupancy on tighter deals. Build the draw package as the work happens, and negotiate staged releases before signing; the float is real and someone is funding it.
Interior contractors at $1M to $5M net 5.5 percent on average, rising to 8 percent by $25M to $50M; the CFOS target at $1M to $5M is 10 percent. The trade's leaks are TI-float carrying cost nobody priced, work-letter scope seams, and building-rules friction discovered mid-project instead of bid day. Every net profit figure here is stated before taxes, the same basis CFMA reports on, so the two are directly comparable.
Walk the building rules before bidding: freight elevator windows, after-hours requirements, noise curfews, protection standards, approved vendors. Each is a production tax with a price; specialists carry them as line items, and generalists discover them on the tenant's schedule.
Three tiers, and which one you are in depends on how much of the work you want off your desk. Core is where you stop guessing: job costing built against the way you estimate, a 13 week cash forecast, monthly WIP, and a monthly meeting that ends in decisions, while your bookkeeper keeps doing the books. Executive is where you stop touching the books, because we run the bookkeeping and the controllership as well. Strategic is where every job shows its margin while it is still running, because the job costing and WIP platform is set up and managed for you. No payroll. No scope gaps.
Sixty days. We migrate your books back to the start of your last taxable year, set up ControlQore, and build your job costing structure from scratch. Fully operational in two months.
