Why teams connect Paylocity and Plex ERP

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

Paylocity 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 Quality records, Parts, Inventory, Production jobs in Plex ERP with Pay Statements, Company Codes, Custom Fields, Employees in Paylocity 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 Feed quality and scrap data to dashboards supervisors check without logging into Plex.
  • 02 Sync production and inventory data from Plex into a warehouse or Postgres for plant-level analytics.
  • 03 Upsert recurring Deductions and Earnings on employee records when benefits or 401(k) elections change in a benefits admin system, without re-keying payroll setup.
  • 04 Read Pay Statements and Direct Deposit allocations into a Postgres or warehouse database for labor-cost, GL, and headcount reporting in SQL.

Common sync patterns

New hires ready to transact in Plex ERP

A new person set up in Paylocity becomes an employee record in Plex ERP in time to submit expenses, enter time, or approve a purchase, without waiting on manual setup.

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 Paylocity maintains.

Reporting lines drive approvals

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

How changes propagate between Paylocity and Plex ERP

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.

Paylocity Plex ERP Sub-second propagation

DetectionPaylocity notifies Stacksync of record changes through webhook events. Webhooks — Paylocity POSTs Employee New Hire, Employee Change, Termination, Payroll Processed, and Time Off Approval events to a callback URL.

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

Plex ERP Paylocity 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 Paylocity through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Paylocity: 25 requests per second (1,500 per minute); exceeding it returns HTTP 429. Every path is scoped to a Paylocity-assigned companyId (a company code, not a UUID).
  • Plex ERP: Subject to the platform's API rate limits.

How the Paylocity and Plex ERP connectors work

Paylocity

Integration surface
REST API (v1 and v2), JSON payloads
Authentication
OAuth 2.0 client credentials via the Paylocity Identity Provider (/IdentityServer/connect/token) with the WebLinkAPI scope; access tokens expire after one hour and API access must be enabled by Paylocity for the company
Change detection
Webhooks — Paylocity POSTs Employee New Hire, Employee Change, Termination, Payroll Processed, and Time Off Approval events to a callback URL; payloads carry only companyId and employeeId, so the receiver calls the relevant API to fetch changed values. Scheduled polling is used for objects without webhooks.
