Paychex Flex is a solid payroll processing system best liked for its ease of use, positive customer service interactions, fair price and useful functionality. However, it comes with several drawbacks as well. While it’s easy to use, the onboarding takes time and can be initially frustrating. The customer service is good but the high turnover with representatives can be trying. A small but significant percentage had problems with the time and attendance features, either having issues with their punches not being registered or issues with the physical biometric clocks. Overall, it seems best for small and medium businesses looking to automate their payroll. Any organization with multiple types of workers, complex pay rules or many different kinds of income to report should be sure to demo the system carefully and may want to find a more complex option.
