Client Testimonials

Taylor P.
“My small hobby business suddenly started to take off, and I was having a hard time keeping track of all my business transactions and expenses. I knew I would need to outsource my bookkeeping in order to avoid falling behind. Abacus Tax & Books offered an affordable solution that perfectly met my needs.”
Kenneth F.
“I received a letter from the IRS regarding my tax return from 2 years ago. I wasn’t sure what the issue was, and I was worried that I would owe additional money, which could cause my family significant financial hardship during an already difficult time. Abacus Tax & Books helped me get together the proper forms and paperwork I needed, and offered me guidance and advice about the audit process to make sure I was prepared. They helped me resolve the problem quickly with minimal stress.”
