"I’ve been a client of ROI Business Services since 2009... and I couldn’t be more satisfied. ROI took over the accounting for my corporation when it was experiencing fast growth, $1M+, with employees and vendors located in several states. (ROI's) team is very detail-oriented, asks the right questions, and all returns and filings are done promptly and accurately. I have great trust in ROI and highly recommend them for both business and personal tax needs." - Jean J., Naperville
