Most organizations running both UKG and Workday are already sitting on the solution to their biggest payroll and HR headaches. The platforms are live. The data exists. The problem is that these two systems aren’t talking to each other, and the gap between them is being filled by manual effort, spreadsheets, and reconciliation cycles that consume time and introduce real risk.
This isn’t an implementation project. It’s a connection project. And the cost of not doing it is higher than most leaders realize. When UKG and Workday communicate effectively, the benefits compound quickly. Organizations that delay integration tend to find out what it’s costing them through payroll errors, compliance exposure, and hours lost to manual reconciliation.

This post breaks down the core integration capabilities, available technology options, emerging AI trends, and practical implementation considerations — and where Surety Systems can help your team connect these two platforms the right way.
What Leaders Are Actually Trying to Fix
The conversations we have with HR, payroll, and operations leaders come back to the same problems. These aren’t technology failures; they’re data flow failures between two systems that either have not been connected properly or have never been connected at all. The fix isn’t a new system. It’s connecting the ones you have and ensuring the right data flows in the right direction.
- Payroll errors that trace back to org changes or job transfers made in Workday that never reached UKG
- Hours spent manually reconciling timekeeping data between systems every pay period
- Managers scheduling against inaccurate PTO balances because accruals aren’t syncing in real time
- New hires who exist in Workday but can’t clock in on day one because UKG hasn’t been updated
- Finance and HR reporting that doesn’t match because labor cost data lives in two places
HR teams spend 18–22% of their time managing system issues and data movement rather than strategic work. For a five-person team, that’s nearly one full-time equivalent absorbed by maintenance that integration eliminates. — HR Research Institute, 2025
What Integration Unlocks: Outcomes by Business Function
| Business Problem | What Gets Connected | Outcome |
| Payroll errors from manual re-entry | Org changes, job codes, pay groups flow automatically from Workday to UKG | Cleaner pay runs, fewer corrections, reduced compliance exposure |
| Managers scheduling against stale data | PTO accruals sync continuously between systems | Accurate availability data before every shift assignment |
| New hire delays on day one | Employee lifecycle events trigger automatic UKG record creation | Employees clock in and access schedules from day one |
| Time-consuming pay period reconciliation | Approved time, overtime, and differentials flow from UKG to Workday | Manual reconciliation eliminated each pay cycle |
| Labor cost data HR and Finance disagree on | UKG operational data feeds Workday reporting and analytics | Single source of truth for workforce cost reporting |
| AI tools that can’t deliver on their promise | Clean, real-time pipelines feed Bryte AI and Workday Illuminate | AI insights that reflect actual workforce state, not stale data |
How It Works: The Integration in Plain Terms
The most important decision in any UKG Workday integration is deceptively simple: which system is the source of truth for which data? Getting that right upfront prevents almost every downstream problem. Here’s how it works:
Workday owns the record of who someone is
New hires, terminations, promotions, transfers, compensation changes, org structure, job codes, cost centers, pay groups, and work locations all originate in Workday and flow to UKG. When Workday changes, UKG reflects it automatically — no manual re-entry required.
UKG owns the record of what someone did
Clock-ins, shift assignments, exception handling, overtime, shift differentials, and time approvals all live in UKG and flow back to Workday to support payroll finalization, finance reporting, and compliance.
The interface makes it directional and automatic
Once source-of-truth boundaries are defined and the integration is configured, the data moves without manual intervention. HR doesn’t re-enter Workday changes into UKG. Payroll doesn’t pull time data manually. The systems stay in sync.
A note on timeline:
Because both systems are already live, this becomes a connection project. Integrations scoped to syncing employee master data and transactional time and attendance data can move quickly when source data is clean, and ownership decisions are clear. The variables that extend timelines are almost always data quality issues, stakeholder alignment, and edge-case testing complexity, not the technical build itself.
What Actually Causes Projects to Stall
Technical build is rarely the hard part. What slows integration projects down falls into three categories — all of which can be addressed before the build begins:
1. Data that was never cleaned
Mismatched employee IDs, inconsistent cost centers, duplicate department hierarchies, pay rules that exist in one system but not the other. Automating a messy data set accelerates the mess. A targeted data audit before integration begins is the single highest-leverage preparation step most organizations skip.
2. Unclear ownership decisions
When it’s not settled whether Workday or UKG owns a particular field, such as job code, cost center, supervisor hierarchy, both systems compete for source-of-truth status and create conflicts. These decisions belong to the business, not to the technical build.
3. Missing stakeholders
The people who know where edge cases like union rules, contingent worker classifications, shift differentials, retroactive adjustments live are often not in the room when integration requirements are defined. Getting payroll, operations, and compliance into the design phase prevents expensive late-stage surprises.
The AI Factor: Why Integration Quality Matters More Now
Both UKG and Workday have moved aggressively into AI-powered operations. UKG Bryte AI, now built on Google Cloud with Gemini and BigQuery, supports payroll insights, schedule optimization, and employee self-service. Workday Illuminate embeds AI agents directly into HR, finance, and workforce planning workflows. Both platforms are expanding these capabilities significantly through 2026.
The implication is straightforward: both platforms’ AI tools draw on the data flowing through your integration. Stale, incomplete, or misaligned data doesn’t just create reconciliation work; it produces unreliable AI outputs that erode confidence in both systems.
| 5% | Only 5% of organizations have seen real ROI from AI investments — most because AI is being fed incomplete or fragmented data. Clean integration is the prerequisite, not an afterthought. |
Organizations that treat integration as a living data infrastructure rather than a one-time project are the ones positioned to actually get value from AI on both platforms.
Where Industry Context Shapes the Work
The integration pattern is consistent across industries. What varies is the complexity of pay rules, the regulatory stakes, and the operational cost of errors.
Healthcare
Scheduling clinical staff across 24/7 operations with floating assignments, certification requirements, and overtime rules creates meaningful complexity in the UKG-to-Workday data flow. Compliance adds urgency: the overtime tax benefit signed into law in July 2025 introduces new payroll calculation requirements that depend directly on accurate, well-integrated time data.
Manufacturing and Distribution
Multi-site operations with shift differentials, union contracts, and complex pay rules require precision in how UKG configurations map to Workday pay groups and cost centers. Errors that seem minor in testing surface quickly at scale across large hourly workforces.
Retail and Hospitality
High turnover, variable scheduling, and multi-location management make the new hire and termination sync between Workday and UKG especially high-volume and high-stakes. This data flow has a direct, daily impact on scheduling coverage and payroll accuracy.
What a Well-Run Integration Delivers
| Pay period reconciliation Eliminated for most organizations once the time-and-attendance sync is live and tested. | Day-one employee access New hires in UKG automatically when Workday onboarding completes with no manual step. |
| Scheduling accuracy Managers work from real-time PTO and accrual data, not what was synced last week. | One source of truth Finance and HR finally agree on labor cost data and no separate reconciliation process. |
These outcomes are not the product of a complex, multi-year transformation. They are the result of clearly defined data ownership, clean source data, a well-tested build, and a governance model that keeps both systems in sync as the business changes.
