Bookkeeping & Payroll Services for Business Owners
Hi, I am Denise Iacono, founder of Bayside Books. I serve as your trusted, outsourced bookkeeper providing professional bookkeeping services and payroll support without the cost or complexity of hiring in-house.
With over 20 years of experience in the financial industry, I help business owners in Holbrook, Ronkonkoma and across Long Island - including Attorneys, Dentists and Veterinarians - reclaim dozens of hours each year and uncover thousands in missed profit - all through streamlined, accurate bookkeeping.
Whether you're behind on your books, need monthly support, or want to reduce tax-time stress, I offer flexible solutions that let you stay focused on growing your business while I handle the numbers.
Let Bayside Books help you take control of your finances so your books work for you, not against you.

Falling behind doesn't have to mean starting from scratch.
I specialize in bringing months, or even years of financial records up to date quickly and accurately, so you can make confident decisions and get back in control. Whether you're an Attorney, Dentist or Small Business Owner, I'll help you catch up without overwhelm.
Your records should tell the same story as your bank and credit card statements.
I match and verify every transaction, ensuring nothing's missing, duplicated, or miscategorized. That means cleaner books, better reports, and fewer surprises.
Your team gets paid on time. Your filings stay compliant.
From regular payroll runs to quarterly tax filings, I manage the details so you can focus on growing your business - not worrying about deadlines. I work with small practices and professional firms to simplify payroll and reduce stress.
