FRACTIONAL CFO FOR INTERIORS CONTRACTORS.

QUICK ANSWER

We manage the finance side for interiors subcontractors doing $1M to $12M. You get job costing aligned to the way you estimate, a 13 week cash flow forecast, monthly WIP, and a CFO in the room every month. Pricing starts at $1,900 per month.

Interiors fit-out gets paid by a tenant who gets paid by a landlord, so the draw package is the whole cash system. Allowances are $15 to $80 a square foot. They reimburse 30 to 60 days after a clean package of paid invoices, lien waivers and completion proof, and some deals release nothing until certificate of occupancy. We build that package as the work happens. That decides whether you collect the draw or pay for the landlord's building. We also price the work letter before the drawings. Base-building against tenant scope is set in the letter, and every seam you don't read, from demising walls to a code-triggered panel upgrade, turns into unpaid scope later.

WHERE INTERIORS LOSES MONEY

THE THREE THINGS THAT DRAIN THE CASH.

LEAK 01

The Reimbursement Float

TI money goes from landlord to tenant to contractor. It's released 30 to 60 days after a clean draw package, and sometimes only at certificate of occupancy. Build lien waivers and invoice packages as the work happens and you get the draw. Put them together at month end and you pay for the landlord's building.

LEAK 02

The Work-Letter Seam

The work letter decides base-building versus tenant scope. The drawings don't. Every seam you don't read (demising walls, panel upgrades, code-triggered base work) turns into unpaid scope. Price the letter, then the plans.

LEAK 03

The Lease-Date Vise

Rent commencement is in the contract. Permits take 4 to 12 weeks and switchgear takes 18 to 30. The schedule works backward from a date you never chose. Long-lead procurement and a contingency you hold to are the only slack you have.

THE MATH

FROM 6% TO 10% NET.

At $1M to $5M, the average interiors sub earns 19% gross margin and spends 13% of revenue on overhead. What's left is 6% net profit before taxes (Run On CFOS Trade Benchmark Reference). The CFOS target is 10% before taxes. That is the interiors average plus 3.5 points, and never below 10%. The book CONTROL's 12% is the rule of thumb across trades. It is not the industry average.

Two changes get you to the target. Overhead comes down 1 point to 12%, and gross margin comes up 3 points to 22%, so 22 minus 12 leaves 10. The gross margin points come from the three problems above, once you price them and bill for them. On a $3M year, every point is $30,000.

HOW SPM FIXES IT

WHAT WE CHANGE.

These are the interiors problems we put a number on first. Each one gets its own cost code, its own line on the schedule of values or its own line in the 13 week cash forecast, so you can read it in the monthly meeting while the job is still open.

GAP CALCULATOR

THE INTERIORS GAP CALCULATOR. AVERAGE AGAINST TARGET, IN DOLLARS.

Put in your annual revenue. You get gross margin, overhead and net profit for interiors contractors your size: the industry average and the CFOS target, in dollars a year. Nothing you type leaves this page.

Why aim for the target. An average is the middle of the pack: about half of companies do worse. And about 6 in 10 construction businesses close within 10 years (U.S. Bureau of Labor Statistics: about 40 percent of construction businesses opened in 2013 were still open in 2023). So the business in the middle is one of the ones that close. On those numbers, average is a business that closes within 10 years. That is why the CFOS target is a requirement.

The onboarding fee covers migrating your books back to the start of your last taxable year and getting you fully operational in 60 days. It's billed once, with your first invoice. It's the same for all three tiers, and it moves with your revenue band. Your first month is prorated, and your monthly engagement starts on the first of the first full month.

Just want the setup? Onboarding only is the same onboarding work with no monthly service after it, one time, at the onboarding fee plus $2,000. Start a monthly engagement later and $2,000 counts toward it. It starts at $4,500, and the price for every band is on the pricing page.

The three tier columns are the whole price. Which one fits depends on how much of the work you want off your desk. No payroll. No hidden line items. The onboarding fee is right here in the table.

  • Online software only: QuickBooks, Sage, Viewpoint and similar. No VPN or hosted desktop.
  • Not in any tier: payroll, pay applications, collections on receivables.
  • Pricing valid through 2027.

COMMON QUESTIONS

FREQUENTLY ASKED.

Interior contractors at $1M to $5M net 6 percent on average, rising to 13 percent by $25M to $50M; the CFOS net profit target is 10 percent before taxes at $1M to $5M, since the target is the trade average plus 3.5 points and never below 10. The money goes to TI-float holding cost nobody priced, work-letter scope seams, and building rules you find out about mid-project when you should have known on bid day. Every net profit figure here is gross margin minus overhead, stated before taxes, the same basis CFMA reports net income on.

See the full benchmarks for every revenue band on Run On CFOS.

Usually it needs the CFO work, and a full time CFO is more than it needs. At $5M to $10M, interiors subs average 9% net profit before taxes (Run On CFOS Trade Benchmark Reference), and the CFOS target is 12.5%. On $5M of revenue every point is $50,000, so that difference is worth $175,000 a year. A full time CFO costs $150,000 or more in salary alone. SPM's published price for $3.5M to $6.5M is $3,800 a month for Core to $8,300 for Platinum.

Landlord to tenant to contractor, after the work is done. You bill the tenant. The tenant submits a draw package (paid invoices, lien waivers, completion proof) to the landlord. Reimbursement comes 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 you sign. The float is real and someone is paying for it.

The lease exhibit that defines base-building versus tenant scope, allowance mechanics, change-order rules, schedule milestones and landlord-delay damages. The scope seams are in there: demising walls, panel capacity, code-triggered base work. Price the work letter first. The drawings only show what someone thinks the letter said.

Walk the building rules before you bid: freight elevator windows, after-hours requirements, noise curfews, protection standards, approved vendors. Each one costs production and has a price. Specialists price them as line items. Generalists find out about them on the tenant's schedule.

Schedule backward from the lease's rent-commencement date. Order long-lead equipment on day one (switchgear alone can take 18 to 30 weeks). Talk to the permit jurisdiction during design. Build in the 10-to-15 percent contingency, because the unseen conditions in existing buildings will use it.

A bookkeeper records history. Draw-package habits, work-letter scope mapping, long-lead cash planning and trade-package buyout tracking make up a control system, and that's CFO work. SPM does that CFO work for interior contractors.

Three tiers, and which one you are in depends on how much of the work you want off your desk. On Core we build your plan every month and your team does the work: 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. On Strategic we build the plan, track it and adjust it every month: our team does the bookkeeping and the bank reconciliations, and the job costing and WIP software is set up and managed for you, on your own online software or ours. On Platinum we manage the money side for you every week: our team handles your bills and receivables the way an in-house controller would, and you approve every payment. We don't do payroll.

Sixty days. We migrate your books back to the start of your last taxable year and build your job costing structure from scratch, and on Strategic and Platinum we set up the job costing and WIP software too. You're fully up and working in two months. The onboarding fee is one time, the same for every tier, and set by your revenue band.

ControlQore is the job costing and WIP platform we use on the Strategic and Platinum tiers. It's built for contractors, costs less than the older tools, and has AI built in. We set it up and manage it, so you do not have to learn it. Core is the CFO work only, so it does not include the software.

A bookkeeper records what happened. We tell you what it means and what to do about it. We align job costing to your estimates, track WIP monthly, and hold a monthly meeting where you decide what to fix and who fixes it.

THE CHEAPER OPTION WORKS AND TAKES LONGER.

If price comes first, plenty of CFOs and bookkeepers can get your construction company results. It often takes the better part of a year.

If you're a trade contractor, a sub or a GC who wins work, keeps the crews busy and still can't figure out where the money goes, we get in the weeds with you. We change the processes that cost you money on every job, build the ones you're missing and give you the formula, so you see results in 60 to 90 days.

Our guarantee holds when you come to every meeting, do the process and keep a strong pipeline of work. We can fix how your work pays. We can't fix having no work.
