Apex HCM is a US-based human capital management software vendor that participates in the NetSuite partner ecosystem as a Technology Partner. Founded in 2008 and headquartered in Roswell, Georgia, Apex develops payroll, tax filing, HR, and time-and-attendance applications used by service bureaus and small-to-mid-market employers. The company's products are positioned to complement NetSuite's SuitePeople and core ERP modules where customers need specialised payroll processing in the United States. According to public statements from the company, more than 300 payroll service firms use Apex's platform as the foundation of their offering. In February 2023, Apex HCM was acquired by IRIS Software Group, a UK-headquartered HR and accounting software company, expanding IRIS's North American payroll footprint. As a Technology Partner rather than a Solution Provider, Apex does not implement NetSuite itself; the partnership focuses on data integration so that payroll, time, and HR information can flow between Apex and NetSuite environments. Apex serves customers across professional services, technology, and healthcare verticals among others.
