  • We are a medium-size nonprofit. We have used GNSA for both our timesheet system and our payroll processing. What I have enjoyed the most about GNSA is the customer service. I can't recommend the company enough. There are plenty of payroll companies but GNSA stands out because of their excellent customer service. The staff is always quick to answer my questions and when I first came on, they even sat with me on the phone while I processed payroll. They are friendly, courteous, thorough, and know their system. As with any computer type system, it's the customer service that makes all the difference and at GNSA, it really couldn't be better. I recommend it highly to any of my nonprofit colleagues.

  • I find the GNSA staff very accommodating when requesting assistance from them. As a non-payroll professional, the GNSA staff is very patient in not only listening and understanding our concerns but also in supplying trouble shooting and recommendations, allowing me and my team to quickly move to resolution. With a complicated HR model, GNSA allows my organization to precisely monitor all our payroll needs.

  • We find the customer service support the most valuable resource with working with GNSA. We have been processing our payroll with them since 2016, and have consistently received quality service. We were looking for strong payroll and tax knowledge to supplement the experience on our internal payroll team, and GNSA has been a great partner. We would highly recommend them for anyone looking for accessible, friendly, and knowledgeable payroll support services.
