What Others Say

“Foyr has enjoyed working with Stephano Slack over the past 2 years. The team has been very helpful in performing all the accounting services we get from them and they are very attentive to our changing needs. We have come to enjoy the relationship with them.”


“We have used Stephano Slack for our companies’ outsourced accounting and financial consulting for the past several years. As a franchisor accurate financial data and reporting is critical. Blake Chapman and the entire group are highly responsive and first class in their execution. I would highly recommend them to any group seeking a strong financial partner.”


“Working with Stephano Slack over the past several years has been a positive experience because of their expertise and professionalism. We couldn’t have asked for a better partner for our growing business!”


“Stephano Slack’s accounting department is a key part of our team assisting with many aspects of our business, including grant management and tax filings. They are extremely knowledgeable in small business issues and provide expert support and give us a high-level of confidence in our financial management. The team is very responsive and provides excellent customer service.”


“The key takeaways for me from this relationship beyond providing professional accounting functions and accompanying safeguards are several: you don’t need to be a big fish to be treated like one; my requests are acted upon with a genuine sense of urgency and friendliness; and lastly they understand the value in maintaining cost efficiency that corresponds with our financial goals.”
