ADP pricing is quote-only and not published publicly on its website. Pricing is structured on a recurring base fee plus a per-employee-per-month (PEPM) or per-payroll-run charge. RUN Powered by ADP (for 1-49 employees) is divided into four tiers: Essential Payroll, Enhanced Payroll, Complete Payroll & HR Plus, and HR Pro. For larger mid-market organizations (50-999 employees), ADP Workforce Now and enterprise tiers (ADP Vantage / Lyric HCM) use custom, quote-based PEPM models based on headcount, state tax jurisdictions, pay frequency, and chosen add-on modules.

Because official pricing is not public, costs require a customized quote from sales. Third-party analysis and user reporting indicate RUN Powered by ADP Essential tier starts at approximately $59-$79 base per month (or per payroll run) plus $4-$8 per employee per month. Higher RUN tiers (Enhanced) run approximately $115-$160 base per month plus $6-$10 per employee per month. For ADP Workforce Now, base subscriptions are estimated at $18-$30 per employee per month, with base monthly administrative fees ranging from $150 to $500.

ADP charges separate fees for API access, integrations, and marketplace add-on connectors. ADP API Central for Workforce Now is priced at $2.50 per employee per month for the first 999 employees (scaling down to $1.00 PEPM for enterprise tiers), with optional developer consulting available at $250/hour. Turnkey API Central integration services listed on the ADP Marketplace start at $3,000 for setup plus $4,500/year (for 1-149 employees). Third-party marketplace app integrations (such as 401(k) or state IRA syncs) carry flat monthly fees scaling by headcount (e.g., $40/month for 1-25 employees).

REST API using JSON payloads and OAuth 2.0 authentication with mutual TLS (X.509 certificates).

Gated behind paid subscription and partner/client authorization. Direct client access requires purchasing ADP API Central. Partner integrations require acceptance into the ADP Marketplace Partner Program, generation of mutual SSL certificates, OAuth 2.0 client credentials, and client consent.

Rate limits and concurrency limits are strictly enforced (ADP API Central allows up to 120 requests/min with 10 concurrent requests; Marketplace apps default to 300 requests/min with 50 concurrent requests). Access tokens expire in 60 minutes. Endpoints support read and read/write operations subject to role-based data entitlements, with functional limitations on updating multi-effective-date custom fields.

ADP provides a custom report builder supporting manual exports to CSV and Excel, as well as recurring scheduled report delivery via email or SFTP using ADP's Automatic Export Service (AES).

ADP integrates with general accounting and construction-focused ERP systems including QuickBooks (Online and Desktop), Sage Intacct (including Sage Intacct Construction), Xero, NetSuite, FinancialForce, and Wave. Field and project management (PM) connections include Procore, ClockShark, and allGeo. Integrations between ADP payroll and accounting/field systems function through both native/co-developed connectors (e.g., the direct 'Sage Intacct Payroll powered by ADP Workforce Now for Construction' and ADP General Ledger Interface) and third-party integration platforms (e.g., Flexspring for Procore-to-ADP sync, DataBlend, and Workato).

ADP operates a public app marketplace and partner ecosystem called ADP Marketplace (apps.adp.com). It serves as a storefront and developer portal featuring pre-built API connectors, partner applications, and developer tools for products including RUN Powered by ADP, ADP Workforce Now, ADP Lyric, and ADP Vantage HCM.

ADP is a payroll/HCM platform rather than a full general ledger accounting system; however, it supports payroll journal entry exports and general ledger integrations for both accrual accounting (payroll accrual journal entries) and cash-based reporting.
