When payroll runs in UKG, the journal entry appears in Microsoft Dynamics 365 Finance automatically — nobody retypes it. Flexspring connects Dynamics 365 to UKG Pro, UKG Ready and UKG Pro Workforce Management directly, so payroll data, employee records, approved timesheets and expense reimbursements move between the two systems in near real time over an API-to-API connection.
The payroll journal entry is summarised into one entry per payroll run per legal entity, grouped by department or location if you need it, and carries no detail about individual employees’ pay. The integration balances debits and credits and notifies you if anything does not reconcile. One connector covers a single legal entity; another covers payrolls mapped to multiple entities.
Flexspring is one of the leading sellers of custom connectors for UKG, and its experts do all the custom data mapping and maintain the connection afterwards, so no internal IT resource is needed. With Flexspring, you only pay for the use case or use cases you need.
Everything below moves automatically between Microsoft Dynamics 365 and UKG. Approved timesheets and expense reimbursements flow from Dynamics 365 into UKG for payroll; payroll journal entries and employee records flow back from UKG into Dynamics 365 Finance.
