BambooHR has been a go-to HR solution for small- and medium-sized businesses (SMBs) for years, with modules covering nearly every HR process — from hiring to payroll, benefits, time tracking, and performance management. BambooHR stands out to me for its plug-and-play HR workflows, pre-built reports, and easily navigable interface that requires little training.

If you're growing and need flexible support for unique business cases, ADP's Workforce Now HR software is a worthy consideration. It offers the largest selection of native solutions to handle the evolving needs of midsize businesses, including global payroll in more than 140 countries, benchmarks for strategic workforce planning, and even business advisory services. ADP also has one of the largest integration libraries on the HR software market, allowing you to connect accounting, business intelligence, and collaboration tools for a centralized system to handle all your people processes as you grow.

OnPay is the most affordable platform on our shortlist, with a one-size-fits-all pricing model and no additional implementation or data migration fees. Their $49 + $6 PEPM price even includes multi-state payroll support, which rivals Gusto’s starter subscription plan. I also like that OnPay focuses primarily on small-business HR needs, providing federal, state, and local tax compliance, along with simple reports and an internal human resources information system (HRIS) for managing performance reviews, employee rosters, and internal communications.
