Why teams connect Plex ERP and Ukg Pro

Sync the workers, org structure, and cost centers that Plex ERP and Ukg Pro share in real time, so the people Ukg Pro manages stay current in the system that runs finance and operations.

Ukg Pro is the system of record for people: who was hired, which department and location they sit in, who they report to, and how they are paid. Plex ERP runs finance and operations, and much of what it does depends on that same information, from booking labor cost to approving an expense report to staffing a project. Where the two are bridged by re-keying or an overnight file, each side spends the day out of step, with new hires missing from the systems they need and leavers still active where they should not be.

Stacksync syncs Parts, Inventory, Production jobs, Sales orders in Plex ERP with Employee (Person Details), Employment Details, Job / Position History, Compensation Details in Ukg Pro field by field, in real time, and in both directions. You decide which system owns which fields, so the people side stays authoritative for worker data while Plex ERP keeps its own accounting and operational detail, and every change made in one is reflected in the other within seconds instead of at the next batch run.

Common use cases

  • 01 Mirror purchase orders and receipts to accounting or planning tools.
  • 02 Feed quality and scrap data to dashboards supervisors check without logging into Plex.
  • 03 Keep Configuration code tables (jobs, locations, departments, cost centers) aligned between UKG Pro and an ERP so org and cost-center hierarchies match.
  • 04 Two-way sync of Employee and Job Details (position, department, supervisor, location, cost center) into Postgres so provisioning, internal apps, and analytics read current worker and org data in SQL while HR edits in UKG Pro.

Common sync patterns

One org structure

Departments, cost centers, and locations that both systems reference stay in agreement, so labor cost, approvals, and reporting in Plex ERP roll up to the same structure Ukg Pro maintains.

Reporting lines drive approvals

Manager and reporting-hierarchy changes in Ukg Pro keep expense and purchase approval chains in Plex ERP pointed at the right people.

Where Ukg Pro runs payroll: labor cost in the books

Pay and compensation data from Ukg Pro posts into Plex ERP as labor cost, so finance sees workforce spend without re-entering it by hand.

What you can sync between Plex ERP and Ukg Pro

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Plex ERP objects Ukg Pro objects How this pairing syncs
Inventory On-hand balances and locations replicated for visibility outside the plant system Job / Position History Effective-dated job, position, department, supervisor, location, and cost center; the most-synced record for org charts, provisioning, and analytics. Inventory is specific to Plex ERP and Job / Position History to Ukg Pro — each maps to any object or custom field on the other side.
Production jobs Shop-floor work records combining ERP and MES data for output reporting Compensation Details Effective-dated pay rate and salary; usually read into a warehouse for comp reporting and writable as new dated changes through the compensation endpoints. Production jobs is specific to Plex ERP and Compensation Details to Ukg Pro — each maps to any object or custom field on the other side.
Sales orders Demand records written in from e-commerce or EDI channels and read out for fulfillment status Payroll (Pay Statements, Direct Deposit, Earnings) Pay statements, direct-deposit accounts, and earnings history; read-only pay data replicated into finance and warehouse systems for labor-cost reporting. Sales orders is specific to Plex ERP and Payroll (Pay Statements, Direct Deposit, Earnings) to Ukg Pro — each maps to any object or custom field on the other side.
Purchase orders Procurement records mirrored to accounting and planning systems Terminations Termination transactions posted with a terminationDate and a reason code that must match the tenant's configured reason table; drives account deprovisioning. Purchase orders is specific to Plex ERP and Terminations to Ukg Pro — each maps to any object or custom field on the other side.
Customers Account records kept consistent with the sales team's CRM Configuration Setup (Code Tables) Reference data such as jobs, locations, positions, earnings, and deduction codes; used to resolve and validate field values when mapping records during sync. Customers is specific to Plex ERP and Configuration Setup (Code Tables) to Ukg Pro — each maps to any object or custom field on the other side.
Suppliers Vendor records aligned with procurement and AP tools Time & Attendance (UTA) Timekeeping and worked-hours data exposed by the UTA services; synced into scheduling, payroll, or workforce-analytics databases. Suppliers is specific to Plex ERP and Time & Attendance (UTA) to Ukg Pro — each maps to any object or custom field on the other side.

How changes propagate between Plex ERP and Ukg Pro

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Plex ERP Ukg Pro Interval-based propagation

DetectionStacksync polls Plex ERP for changes on an incremental schedule, reading only records changed since the previous pass. Polling.

DeliveryEach detected change is written to Ukg Pro through its API, with automatic retries and rate-limit backoff.

Ukg Pro Plex ERP Sub-second propagation

DetectionUkg Pro notifies Stacksync of record changes through webhook events. No CDC stream.

DeliveryEach detected change is written to Plex ERP through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Plex ERP: Subject to the platform's API rate limits.
  • Ukg Pro: An API gateway throttles calls per client over a rolling window (typically per minute); UKG does not publish exact numeric thresholds. Exceeding the limit returns HTTP 429, and UKG recommends a roughly one-second looping backoff before resuming (a Retry-After header is not yet standard). Reads are offset-paginated.

Authentication
Core HCM REST APIs use HTTP Basic authentication with a dedicated web service account, plus a Customer API Key and a User API Key sent as headers (found under System Configuration > Security > Service Account Administration); the Onboarding and Recruiting REST APIs instead require a bearer Authorization Token from the token endpoint.
Change detection
No CDC stream. UKG Pro publishes Pro HCM Webhook Events for changes such as new hire, employee and job detail changes, termination, and PTO, which Stacksync subscribes to for near-real-time triggers; bulk and historical loads use paged reads with each service's modified-since filters.
