ADP Workforce Now

ADP Workforce Now is a cloud-based payroll and HR platform for mid-sized businesses, covering payroll processing, tax compliance, benefits administration, time and attendance, and talent management in one system.
Accounting firms encounter ADP frequently as a client payroll system and use its reporting capabilities to extract data for tax preparation, financial statements, and audits. ADP handles federal, state, and local payroll tax calculations and filings automatically, and its general ledger integration exports payroll journal entries to accounting platforms. ADP also offers an accountant program that provides firms with tools to manage payroll on behalf of multiple clients.
The platform scales from basic payroll to full HCM (human capital management) depending on the modules a business subscribes to. It is best suited for mid-sized US businesses (50–1,000+ employees) that need payroll tightly integrated with HR and benefits. Smaller businesses often find ADP Run or lighter alternatives more appropriate.
