Construction Accounting & Fractional CFO Services for California Contractors

Most CPAs are spreadsheet-heavy, but ours is decision-focused.

Profit on paper doesn’t pay payroll. Without cash flow visibility, you’re always reacting.  Costs blur together and margins get squeezed without warning. One bad month or one slow client can disrupt everything.

Our team of CPAs and accountants builds financial systems that match the way your construction business operates.

The Real Financial Challenges We Solve

These aren’t accounting problems. They’re business problems, and California businesses face them every day. The right financial partner can solve them before they become crises.

Cash flow gaps

Profit on paper doesn't pay the bills. We build cash visibility at the level your construction business runs on — by job, client, month, or scenario.

Jobs that look profitable until all the costs are counted

Labor burden, subcontractors, materials, equipment, rework, and shared overhead can turn a good-looking estimate into a weak-margin job. We help make those costs visible earlier.

Growth that outpaces infrastructure

Hiring or expanding without financial guardrails strains cash. We help you plan growth instead of reacting to it.

Unpredictable margins

We identify where profit is leaking and create pricing strategies that protect margin without slowing momentum.

Tax drag & missed deductions

We review entity structure, compensation, estimated taxes, deductions, depreciation, and major purchases throughout the year so tax decisions are made before deadlines close off your options.

We partner best with construction businesses that:

Samy Basta, CPA

Fractional CFO & Accounting Services in San Francisco, California

Most California construction companies hit a growth bottleneck because their financial systems are too simple. Strategic financial leadership, proactive reporting, and tailored infrastructure help San Francisco business owners navigate these challenges.

“Basta & Co. was recommended to us after we had a series of bad experiences with other accounting firms. We look forward to tax season with Samy in charge of our complex tax situations.”

Sharon Ching

SLM Architecture and Design

What a great surprise! We were expecting to pay IRS over $10,000 in additional taxes but we ended up with $4,000 tax credits and paid nothing! Samy is amazing! He knows all the recent tax reforms and patiently explains them to us and applies the relevant tax deductible tools and strategies for our business and personal taxes.

Elmira Esmaeili

As a new client I’m delighted to report that my interactions with Basta & Company have been excellent.  I’m grateful for the invaluable assistance I’ve so far received from Basta & Company, and staff!


John Meloy

I cannot recommend Samy enough! He helped us with a very challenging 1031 exchange which allowed us to defer our capital gains taxes and purchase a new property. He returns e-mails and phone messages promptly and the best part is that he talks non CPA language to you in order to make sure you understand everything. If I could, I would give him 6 stars!
