Paychex Flex offers the full range of services for HR outsourcing, including payroll, taxes, benefits, recruiting and training; and they do so without requiring a long-term contract. More uniquely, Paychex also offers an on-site assistance program that puts HR professionals in the office when customers need more help. While many outsourcers offer services like employee handbooks and guidelines, they're often nothing more than boilerplate. Paychex will create a robust set of guidelines customized to meet the needs of each client. Their website also offers significant educational resources on a wide range of HR topics. One downside, however, is that Paychex doesn't offer a live chat function, so clients still have to depend on telephone options. They also offer special programs for businesses with fewer than 50 employees, making them a standout provider for small companies.
In addition, Inc.com did a review of Paychex Flex, saying: “Paychex Flex is one of the strongest, if not THE strongest, name in online payroll services.”
