IN YOUR BUSINESS,
WHO OWNS
THE FINANCIAL FUNCTION?

QUICK ANSWER

In most subcontracting businesses, nobody owns the financial function. The owner is too busy running jobs. The bookkeeper records transactions and moves on. The CPA shows up at tax time. Nobody is watching job margins in real time, forecasting cash, or connecting the estimate to the P&L. That gap is the most expensive vacancy in the business.

Financial ownership means one person is accountable for knowing the numbers, using them to make decisions, and flagging problems before they become crises. In a $5M subcontracting business, that person should be reviewing job cost every month, tracking cash 13 weeks out, and calculating overhead rate from actual costs. If that's not happening — the position is vacant.

THE VACANCY

WHAT HAPPENS WHEN
NOBODY OWNS THE NUMBERS.

01

The Owner Carries It

The owner does the mental math on cash, tries to track AR in their head, and makes financial decisions on instinct. This works until it doesn't — usually when two bad months hit at once.

02

The Bookkeeper Posts and Moves On

A bookkeeper's job is to record transactions accurately. It is not to analyze margins, forecast cash, or connect the estimate to actual costs. Holding them accountable for financial outcomes they weren't hired to produce sets everyone up to fail.

03

Problems Surface Too Late

When nobody owns the financial function, problems surface when the bank balance drops, the LOC is maxed, or a vendor calls. By then the window to fix it cheaply is gone.

WHAT OWNERSHIP LOOKS LIKE

THE RESPONSIBILITIES OF
FINANCIAL OWNERSHIP.

MONTHLY

Close Books by the 10th — Review Every Job

Books closed, reconciled, and accurate by the 10th of every month. Cost to complete run on every active project. CEO report out to ownership. Cash flow forecast updated. These four things, every month, without exception.

ONGOING

Watch AR, Billing Velocity, Overhead Rate

AR aging reviewed weekly. Every invoice over 30 days gets a follow-up call. Every pay application reviewed before submission for front-loading opportunity. Overhead rate recalculated whenever a major cost changes.

STRATEGIC

Connect Numbers to Decisions

Which bid to submit based on current cash position and capacity. Whether to hire before or after landing the next contract. When to draw on the line of credit versus letting AR collection catch up. These are finance decisions that require someone who knows the numbers.

THE SPM MODEL

HOW SPM OWNS
THE FINANCIAL FUNCTION FOR YOU.

Most subcontractors don't need a full-time CFO. They need someone who owns the function — consistently, reliably, every month — without requiring them to manage the process themselves.

SPM becomes the financial function. The owner attends one monthly meeting, reviews the CEO report, and acts on the to-do list. Everything else — bookkeeping, reconciliation, job cost review, cash forecasting, billing oversight, AR follow-up — is handled.

The outcome: The owner runs the business in about five hours a month, financially. Not five hours a day. Five hours a month — all focused on decisions, not data collection. See exactly what the engagement looks like →

FAQ
COMMON QUESTIONS.

In a business doing $1M–$5M, the owner is often the de facto financial owner — by default, not design. At $3M–$8M, a fractional CFO or controller takes over the function, freeing the owner to focus on field operations and business development. At $12M+, a full-time controller with CFO oversight is warranted. The key is that someone is explicitly accountable for all financial outputs — not that it falls to whoever has time.

Books closed by the 10th. Cost to complete on every active project. CEO report distributed. 13-week cash flow updated. Monthly cadence meeting with actionable agenda. AR aging reviewed and followed up weekly. Pay applications reviewed before submission. Overhead rate updated when costs change. This is the complete monthly financial ownership cadence.

Yes — but it requires about 15–20 hours per month at the bookkeeping and reporting level, plus judgment on top of that. Most owners doing $3M+ in revenue don't have 15–20 hours to give to financial management on top of field operations, estimating, and business development. The alternative is a fractional CFO who owns the function and reduces the owner's time to 5 hours of monthly review and decision-making.

The owner attends one monthly cadence meeting, reviews the CEO report, and acts on the to-do list. Everything else is handled by SPM — from weekly bookkeeping through CFO-level analysis and strategy. Most owners experience this as a significant reduction in stress, not just a financial improvement.
