OnPay

OnPay is a cloud-based, full-service payroll platform that runs pay, files and pays federal/state/local taxes automatically, and adds built-in HR and benefits administration in one system. It's aimed at small businesses and startups that want unlimited pay runs for W-2 employees and 1099 contractors at a flat, transparent price. Its main differentiator is affordable, all-inclusive pricing (every feature is included in a single plan) backed by hands-on payroll and tax support.
