A Concierge CPA Practice in Stevenson Ranch

Hay CPAs P.C. is led by Andrew Hay, a California-licensed Certified Public Accountant with over 20 years of experience across real estate, manufacturing and distribution. The practice runs on a concierge model: you work directly with Andrew on every engagement, and each engagement is scoped to what you need. It is built for manufacturers and owner-led businesses that want accurate books, sound tax planning and clear documentation without large-firm overhead.

Andrew combines CPA discipline with AI-enabled workflows. AI speeds up classification, reconciliation and first drafts, and every output is reviewed by a licensed CPA before it reaches you. He has worked in complex regulatory environments from California to the U.S. Virgin Islands, and supports clients in Stevenson Ranch, Thousand Oaks, Agoura Hills, Calabasas, the Santa Clarita Valley and remotely. Compilation and preparation engagements are performed under SSARS (AR-C 80 and AR-C 70).

Service Details

Tax Preparation and Planning

Federal and California returns for individuals, small businesses, S corporations, partnerships, trusts and estates. We plan through the year, covering estimated payments, entity structure and California differences, so the return in April holds few surprises.

Compilations, Financial Statements and Bookkeeping

Compiled financial statements for management and owners under SSARS AR-C 80, and prepared financial statements under AR-C 70. A compilation presents management's financial information as financial statements without assurance. Hay CPAs does not perform audits or reviews.

Bookkeeping, month-end close and prior-period cleanup are available, so the statements and the tax return start from the same reconciled books.

How Concierge Engagements Work

You work directly with Andrew Hay, CPA. It starts with a free initial consultation, followed by a written scope and fee proposal. Many clients work with us remotely. Engagements can be one-time, such as a tax return or a compiled financial statement, or ongoing through the year.

Frequently Asked Questions

What services do you provide?

Federal and California tax returns and compiled financial statements for individuals, small businesses, S corporations, partnerships, trusts and estates. Bookkeeping and tax planning during the year are available, so the numbers tie from the ledger to the return.

What is the difference between a compilation and an audit or review?

A compilation presents management's financial information in the form of financial statements and provides no assurance. Compilations and preparation engagements do not require independence. Hay CPAs does not perform audits or reviews. If a lender or regulator requires assurance, we will say so up front so you can engage an independent firm.

How much does it cost?

Fees depend on scope and complexity. After a free initial consultation, we send a written scope and fee proposal so you know the cost before work begins.
