Your Growth Partner.
Guastella Advisors brings big company financial discipline, clarity, and strategy to the privately held companies that drive the real economy, so owners can focus on what they do best.
The talent of a great CFO, without the overhead.
Small businesses no longer need to choose between a heavy W-2 finance hire and flying blind. GA delivers the rigor large companies take for granted, scaled and priced for the way privately held businesses actually run.
You run the business. We carry the numbers. You get back time, clarity, and a sharper view of every decision in front of you.
If any of this hits close to home, you are not alone.
These aren't signs something's wrong with your business. They're signs you've outgrown the financial setup that got you here.
Let us fix it- The monthly close drags on far too long.
By the time you see the numbers, the decisions they should inform are already behind you.
- Every month brings a surprise expense.
An unflagged vendor bill, a late adjustment, every close lands a hit you didn't see coming.
- Cash flow feels like guesswork.
You check the bank balance more than the P&L. Payroll week is stressful.
- Lender conversations feel like a translation problem.
Bankers and investors see numbers without the story behind them.
- Big decisions get made on instinct.
Hiring, pricing, equipment, expansion, no clear financial picture behind them.
- The books tell you what happened, not what to do.
You have reports. You don't have answers.
This is the work. GA installs the visibility, structure, and rhythm that turn those problems into a system you can run the business on.
GA serves as your financial copilot.
We build the structure, visibility, and strategy intended to support day-to-day operations as they scale.
Owners stay focused on operating the business. We take on the numbers and hand back clarity.
Eight ways we put CFO level strategy to work.
Cash Flow Forecasting
A rolling weekly forecast so you always see what is coming, and decide before it arrives.
Budget vs. Actual Reviews
Monthly variance analysis that reveals the why behind the numbers, not just what changed.
Bank Covenant Reporting
Proactive tracking so covenants are never a quarterly surprise, and your lender stays a partner.
Lender Liaison
GA sits in every lender meeting, translating your strategy into financial standing the bank can underwrite.
Financial Statement Package
Monthly P&L, balance sheet, and cash flow statement. Fully explained. Prepared for management use.
Debt Management & Capital Structure
We engineer the right mix of debt and terms, lowering cost of capital and turning liabilities into leverage.
Accounting Cleanup & Formal Close
A disciplined month end close, fully reconciled, so the books tell the truth and decisions stand up.
Scalability & Growth Strategy
GA turns financial clarity into a roadmap built to support sustainable growth and long-term enterprise value.
Jonathon A. Guastella
Jonathon brings the financial discipline of large enterprises to the privately held companies that drive the real economy. He pairs the technical foundation of a CPA with the strategic lens of an MBA.
Jonathon stays directly engaged on the strategic work for every client, from forecasting and capital decisions to lender conversations and growth planning. The high level thinking does not get handed off.
Every business deserves a high caliber CFO.
Big enterprises have always had access to CFO level strategy, forecasting, and capital discipline. Most privately held businesses have not. GA closes that gap.
How we work →Practical financial leadership, applied with discipline.
CFO caliber thinking, small business scale
Privately held businesses deserve the same caliber of financial guidance as large enterprises. GA bridges the gap, without the full time CFO cost.
Senior judgment, efficient delivery
You get a seasoned finance partner who works the way modern firms do, focused on the decisions that actually move the business, without the overhead of a full time hire.
You operate, we own the numbers
Owners should be focused on customers, people, and product. We carry the financial weight and hand back clarity, so the decisions in front of you get sharper.
Decision support, not just reporting
The right financial foundation does not just track the past. It engineers the future. Pricing, hiring, capex, and capital decisions backed by real numbers.

Common questions from owners.
- Are you a CPA firm or a consulting firm?
- Guastella Advisors, PLLC is a licensed certified public accounting firm registered with the State of Michigan. Our managing director, Jonathon A. Guastella, is a CPA licensed in Michigan. The firm is currently focused exclusively on advisory work such as fractional CFO, financial strategy, cash flow, lender management, and scalability consulting, and does not perform audits, reviews, or compilations.
- Who do you typically work with?
- Privately held, owner led businesses across industries. Professional services, trades and field services, trucking and logistics, healthcare practices, distribution, and other operator led companies preparing for their next growth chapter.
- How is this different from hiring a bookkeeper or controller?
- Bookkeepers record what already happened. Controllers close the month. GA sits a level higher, translating that information into the strategic and operating decisions an owner or CEO actually needs to make.
- How can a small business afford a CFO?
- Modern accounting tools and AI let us deliver senior finance leadership at a fraction of the cost of a full time hire. You get CFO caliber output without the W-2, benefits, and ramp.
- Do you offer tax preparation?
- Tax preparation is not a current core service. GA coordinates with your existing tax advisors and structures the financial picture so tax planning conversations are sharper.
