Fractional Controller & CFO Support

Know your numbers. Grow with confidence.

Big-4 experience. Small-business heart. I bring CFO-level thinking to founders and leadership teams who need real financial clarity — without the overhead of a full-time hire.

What I help with

"What the numbers mean — and what to do next."

Cash flow. Forecasting. KPIs that actually matter. Decisions backed by numbers, not gut feelings.

Services

What I do

Full-cycle accounting and strategic finance — scaled to where you are, built for where you're going.

Financial statements & reporting

GAAP-compliant financials, accurate and on time. I own your month-end and year-end close — and I tighten the timeline.

Cash flow & budgeting

Forecasts and budgeting models that help you plan, not just report. Know your runway before you need to.

KPI development

I work with you to identify, build, and track the metrics that actually drive your business forward — not just the ones that look good on paper.

Systems & workflow setup

QuickBooks Online, Gusto, Bill.com, Divvy, Brex — I implement scalable systems so your ops don't crumble when you grow.

External partner management

I manage your CPAs, auditors, tax advisors, and banking relationships — so you don't have to be the go-between.

Strategic financial guidance

A thought partner for founders — growth planning, profitability analysis, and data-driven strategy at the leadership level.

About

Hi, I'm Sara Hillyer

I started Hillyer Accounting & Strategy after 21 years in accounting and finance because I realized the kind of work I enjoy most just doesn't happen in a big corporate environment.

It's in the details. It's rolling up my sleeves, getting into the books, and working directly with owners and leadership teams who are building something real.

I wanted to work more closely with businesses that need a true financial partner—someone who can clean things up, put strong processes in place, and help make sense of the numbers in a way that actually drives decisions.

I love a good plug-and-play solution, a tight cash flow forecast, and helping founders think through what their numbers are telling them—and what to do next. I enjoy building KPIs that move the business forward and being part of the conversations around strategy and profitability—not just reporting on results.

That's why I built this business: to do the kind of work I'm genuinely good at, with businesses I genuinely care about.
