A440 BOOKKEEPERS
KEEPING YOUR BOOKS IN TUNE
A440 Bookkeepers Bookkeeping for small business and creative professionals.

ABOUT
I’m Michael O’Neill, a Brooklyn-based bookkeeper for freelancers and small businesses. I help you stay organized by accurately tracking income and expenses throughout the year—so tax time is easy and stress-free.
I started bookkeeping in 2006 as an office manager at a props fabrication studio and have since worked with creatives and small businesses across many industries, including therapists, designers, and restaurants. In 2020, I expanded into tax preparation, which strengthened my bookkeeping skills and added valuable perspective.
Outside of accounting, I work in music and performing arts. As a freelancer myself, I understand how busy things get—and how powerful well-kept books can be. My goal is to provide a smooth, judgment-free bookkeeping experience that’s clear, productive, and maybe even fun.
Why A440?
A440 (pronounced “A four forty”) refers to an international tuning standard for the musical note “A” that vibrates at a frequency of 440 Hz. Just as the oboe plays this note so that the rest of the orchestra can tune their instruments, my services will ensure that your books are
exactly where they should be.
