When a new employee is created in any HR app, their record appears in UKG automatically — nobody retypes it. Flexspring connects any HR app to UKG Pro, UKG Ready and UKG Pro Workforce Management, so new hires, employee updates, terminations, approved timesheets and expense reimbursements land in UKG ready for payroll, employee records flow back out to whichever apps need them, and UKG payroll arrives in your finance general ledger as one journal entry per payroll run per legal entity.
Flexspring builds, hosts, and monitors the connection for you and handles all the custom data mapping, and is one of the leading sellers of custom connectors for UKG. There are no files to upload and nothing for your team to maintain. A custom integration goes live in 8-10 weeks. With Flexspring, you only pay for the use case or use cases you need.
Here are the six most popular use cases for integrating any HR app with UKG Pro, UKG Ready or UKG Pro Workforce Management. Each row names the direction the data travels. Flexspring also does custom integration work for one-time payments, banking and tax, learning management, equity systems, background checks, and assessments.

Flexspring iPaaS does not store employee data beyond temporary transaction logs, and meets SOC 2, GDPR and ISO 27001 standards.

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 new employee is created in any HR app, their record appears in UKG automatically — nobody retypes it. Your team gets fewer payroll corrections, faster onboarding, and an end to double-data entry between UKG and the rest of your stack. One community bank’s HRIS analyst saved about five hours every other week.
The best way to connect UKG to your HR app 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.
