“One Small Payroll Company is perfect for us. It’s local, reliable and unlike many big national firms, still responsive even after you sign up. They made the transitions easy and we’ve never had a problem. Letting One Small Payroll take care of your payroll frees you up to take care of your own business. Call them, you’ll be glad you did.”

“I originally worked with Leslie and OSP for two and a half years as a Controller. I then chose to use her services when I opened my own company and I recommend her as much as possible. Our five year relationship could be described as consistent, reliable, and honest. Leslie and her Staff are always there to answer any questions that may be outside of my knowledge base. I would be lost without One Small Payroll!” -Laura Costella


One Small Payroll has been extremely attentive to our needs as a growing business and has worked with us on how to implement payroll changes like a new PTO structure and timesheet mechanics. Leslie and Deja always follows up to our concerns and makes sure our payroll runs smoothly every time” – Universal Property Management

Leslie and her staff are knowledgeable, accommodating, and patient with small business owners who don’t always know the ins and outs of payroll/tax filing.
