ADP

ADP is a US provider of payroll, human resources and tax services, founded in 1949. It serves businesses of every size, from small companies running their first payroll to large enterprises with thousands of employees. Its products cover payroll and tax filing, time and attendance tracking, workforce management, recruiting, benefits administration and business insurance. ADP also works with partners such as accountants, brokers and financial advisers who serve shared clients. For affiliates, ADP suits small business, HR, accounting and startup content, especially guides that compare payroll providers. The programme pays per qualified lead rather than per sale. Because ADP sells mostly through sales consultations, the programme rewards qualified leads, for example small businesses that request a quote or a demo, rather than completed contracts. Lead quality rules usually require real businesses with a minimum number of employees and exclude self-referrals. Affiliates should read the lead criteria in PartnerStack and present ADP alongside other payroll options so readers can compare features and prices fairly.
