About
When a hiring manager presses the hire button in Workday, the new employee’s information appears in ADP automatically — nobody retypes it. Flexspring connects Workday directly to ADP Workforce Now or ADP Vantage HCM, so new hires, employee changes, terminations and approved time off move across in near real time. Your team gets fewer payroll corrections, faster onboarding, and an end to double-data entry between HR and payroll.
Flexspring builds, hosts, and monitors the connection for you. There are no files to upload and nothing for your team to maintain. The essential build — standard fields plus up to five custom fields — goes live in 4–6 weeks; a custom build with more fields and your own business logic takes 8–10 weeks. Payroll journal entries flow back from ADP into Workday, and every other use case is built separately. Flexspring is an ADP Marketplace Platinum Partner and a Workday Marketplace Partner, and you buy your Workday connector on the ADP Marketplace.
Everything below flows from Workday to ADP automatically, except payroll journal entries, which flow the other way — from ADP back into Workday, so wage expenses, tax liabilities and benefits reach your general ledger without anyone rekeying them.
Flexspring iPaaS does not store employee data beyond temporary transaction logs, and meets SOC 2, GDPR and ISO 27001 standards.
Workday to ADP Integration Case Study: A global IT solutions company automates its Core HR to payroll workflow with hands-free data integration.
Read the full case studyA lot of people arrive here comparing the two products. If you’re deciding which single system to buy, that’s a real decision and this guide won’t make it for you.
But many teams don’t choose. They keep Workday as the HR system of record — where managers hire, update records and approve time off — and ADP for payroll, whether that is ADP Workforce Now or ADP Vantage HCM. That works well, right up until someone has to keep both in sync by hand. Disconnected apps are the problem this data integration solves: Workday stays the place people work, and ADP gets clean data on time without anyone retyping it.
With data integration, new hires, employee changes and approved time off move from Workday to ADP automatically, and payroll journal entries flow back from ADP into Workday. 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. Custom integrations by Flexspring include unlimited custom fields and unlimited business rules. There is nothing for your team to install or maintain. You buy your Workday connector on the ADP Marketplace.
With data integration, new hires and employee changes sync, including your custom fields. You can also add one-time payments such as bonuses and stock awards, federal and state tax details and deductions, benefits and allowances, approved paid time off, direct deposit details, time and attendance, departments, locations, jobs, cost centers and business units, interdepartmental transfers, and payroll journal entries flowing back into Workday.
Flexspring builds, hosts, and monitors the connector. The essential build — standard fields plus up to five custom fields — goes live in 4–6 weeks. A custom build with more than five custom fields and your own business logic takes 8–10 weeks. The guide explains which one fits your setup. Custom integration by Flexspring includes unlimited custom fields and unlimited business rules. Flexspring does all the data mapping, so no internal IT resources are needed.
Flexspring does not store employee data beyond temporary transaction logs, and does not require anyone to handle the data manually. Flexspring meets SOC 2, GDPR and ISO 27001 standards.
No internal IT resources are needed to create your data integration. Flexspring’s team builds the integration to your requirements and monitors it afterwards, including handling API changes from either vendor. Your part is deciding which use cases you need and confirming Flexspring’s recommendations for how your fields should map.
With data integration, when a hiring manager presses the hire button in Workday, the new employee’s information appears in ADP automatically — nobody retypes it. Your team gets fewer payroll corrections, faster onboarding, and no double-data entry between HR and payroll.
The best way to connect Workday 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.
The guide includes pricing for each use case, how to choose between essential and custom, and which version fits your team. Sent within one business day.
