I hired Mirror Accounting Services to scrub my profit/loss statement for my business. My income and expenditures are all legal but the numbers had not been reconciled for quite a while! Extremely thorough and detailed, they got me set up with Quickbooks and gave me great recommendations that I've already acted upon. I am now fully confident about my business' financial status and future. I highly recommend Mirror Accounting Services.

I worked with Deborah and she was incredibly responsive and delivered my forms so quickly. She also helped on future planning to reduce my tax liability.
