US S Corporation Bookkeeping & P&L

“Isaiah went through an entire year of expenses both personal and business (US S Corporation, registered in North Carolina) and returned a complete ledger as well as a comprehensive P&L statement. Input was required from me only for essential things that only I would know (for example, was a flight business or personal?). He did this in under two weeks. He was easy to work with. The time I saved by hiring him easily paid for itself many times over. My accountant was also able to take his work and quickly sort my taxes. I would say my fear of an IRS letter has plummeted by at least 85% and I sleep better at night for having hired Isaiah.”
