Flexspring connects NetSuite and ADP in both directions. ADP payroll data becomes summarised journal entries in NetSuite, and new hires and employee updates flow from ADP into NetSuite in near real time. Approved expense reimbursements and NetSuite projects flow the other way into ADP.
Flexspring builds, hosts, and monitors the connection for you. It is an API-to-API connection, so there are no files to upload and nothing for your team to run. Flexspring is a “Built for NetSuite” Integration Partner, and its connector is the only NetSuite connector on the ADP Marketplace. It works with ADP Workforce Now, ADP Workforce Now Next Generation, ADP Lyric HCM, ADP Enterprise HR and ADP Vantage HCM.
New hires and employee updates flow from ADP into NetSuite. This connector also creates payroll journal entries in NetSuite and moves approved expense reimbursements, project labor allocation codes and time card data between the two systems. With Flexspring, you only pay for the use cases you need.

Flexspring iPaaS does not store employee data beyond temporary transaction logs, and meets SOC 2, GDPR and ISO 27001 standards.
With data integration, NetSuite and ADP connect in both directions. ADP payroll data is summarised into one journal entry per payroll run per subsidiary in NetSuite, and new hires and employee updates flow from ADP into NetSuite in near real time. Approved expense reimbursements and NetSuite projects flow the other way into ADP. Flexspring builds the integration to match your custom fields and business rules, then hosts and monitors it.
You decide which information you want to sync, and a data integration expert like Flexspring maps every field between the two systems and builds the connection. The integration extracts each payroll run from ADP and summarises multiple lines of payroll data, such as earnings, deductions and taxes, into one journal entry per payroll run per subsidiary. Amounts can be grouped by department or location, employer tax and benefit contribution data is available, and the integration checks that debits and credits balance and notifies you if anything is out. Custom integrations by Flexspring include unlimited custom fields and unlimited business rules.

Flexspring builds, hosts, and monitors the connector. A custom build is fully deployed in 8-10 weeks, and a turnkey build in 4 weeks.

The best way to connect NetSuite to ADP depends on your data and business requirements. A standard connector can work for simple data flows, while custom fields and unique business rules require a tailored integration. If you go the custom route, you can build the integration yourself or choose a managed integration like Flexspring’s — built and maintained for you, which is typically faster and cheaper.
