Testimonials
very knowledgable and met deadlines I needed. I liked his online portal system which is very easy to use to track documents. Very reasonable rates! He was very flexible and rescheduled an appt I recorded incorrectly- and made time to shuffle his schedule the same day. I would recommend him to others who need small or other business taxes and indiv. returns completed. Plus I prefer to support a small local business vs. any chains or franchise tax prep places!

FREQUENTLY ASKED QUESTIONS
What is the difference between bookkeeping and accounting?
Bookkeeping focuses on recording daily financial transactions, while accounting involves analyzing those records to create financial statements, plan taxes, and guide business decisions. Both are essential for maintaining accurate financial health.
Why should I hire a professional accountant instead of doing my own taxes?
A professional accountant helps you maximize deductions, ensure compliance with tax laws, and avoid costly mistakes. They stay up to date on changing regulations so you receive accurate, optimized tax filing.
How often should a small business update their books?
Most businesses should update their books weekly or monthly to keep financial records accurate and ready for tax season. Regular updates also help you catch issues early and make informed decisions.
