Why teams connect Coupa and Paylocity

Keep the employee, department, and cost records that Coupa and Paylocity share consistent in real time, so the finance system and the people system stop drifting apart.

Coupa runs the money side of the company: who gets paid, what it costs, and which part of the business the cost belongs to. Paylocity runs the people side: who works here, which team they sit in, and how their employment changes over time. The two overlap on the same people and the same org structure, because every employee is also a payee and every department is also a cost center. When that overlap is maintained by hand, a new hire, a transfer, or a termination has to be keyed twice, and the two systems start to disagree about who is active and where the cost lands.

Stacksync syncs Requisitions, Purchase Orders, Invoices, Suppliers in Coupa with Deductions (Pay Setup), Earnings (Pay Setup), Local and State Taxes, Direct Deposit in Paylocity bi-directionally and in real time. A person added, updated, or deactivated on either side appears on the other within seconds, with field-level mapping and conflict resolution in place of CSV exports and nightly batch jobs.

That matters most when money follows a people event. A hire that finance can pay, a leaver whose access ends, a transfer that redirects cost to the right team, all happen from one change instead of two, so headcount and spend reconcile from the same set of records.

Common use cases

  • 01 Export approved Invoices and their lines from Coupa into an accounting/ERP system to drive the AP pay cycle and GL posting.
  • 02 Push chart-of-accounts segments and cost centers from the ERP into Coupa Accounts so Requisitions and Invoices code to the right GL.
  • 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 person becomes a known record in finance

When someone is added in Paylocity, a matching employee or payee record appears in Coupa, ready for payroll, expenses, or cost allocation without anyone rekeying the details.

One employee identity

A person's name, ID, or contact details corrected in either system update the other, so finance and HR reference the same person instead of maintaining two versions.

Department and cost-center alignment

The org structure maintained in Paylocity keeps the departments or cost centers in Coupa current, so spend and headcount roll up the same way.

What you can sync between Coupa and Paylocity

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.

Coupa objects Paylocity objects How this pairing syncs
Contracts Supplier contract records with terms and dates; read out for reporting or created from a CLM system. Custom Fields Read-only company-specific custom fields returned by category, used to enrich the employee record downstream. Contracts is specific to Coupa and Custom Fields to Paylocity — each maps to any object or custom field on the other side.
Expense Reports Employee expense reports and their lines; exported to AP or ERP for reimbursement and GL posting. Employees Core HR record keyed by companyId + employeeId; two-way via Create New Employee (POST) and Update Employee (PATCH), plus Get Employee / Get All Employees for reads. Expense Reports is specific to Coupa and Employees to Paylocity — each maps to any object or custom field on the other side.
Requisitions Employee purchase requests with lines and approval chains; read out to warehouses, or created via the API from upstream intake tools. Onboarding Create Employee Onboarding pushes new-hire data into Paylocity's onboarding workflow; Get Onboarding Status reads back partner onboarding progress. Write-in for hires from an ATS. Requisitions is specific to Coupa and Onboarding to Paylocity — each maps to any object or custom field on the other side.
Purchase Orders PO headers and lines; synced two-way with ERPs so orders raised in Coupa flow to the ledger and status updates flow back on the /purchase_orders resource. Deductions (Pay Setup) Recurring deduction codes at the employee level; two-way via Upsert Deduction and Delete, with Get Deduction / Get All Deductions for reads. Purchase Orders is specific to Coupa and Deductions (Pay Setup) to Paylocity — each maps to any object or custom field on the other side.
Invoices Supplier/AP invoices with lines and approval status; polled out to accounting and ERP systems for the pay cycle, or created through the API. Earnings (Pay Setup) Recurring earning codes at the employee level; two-way via Upsert Earning and Delete, with Get All Earnings and Get by earning code for reads. Invoices is specific to Coupa and Earnings (Pay Setup) to Paylocity — each maps to any object or custom field on the other side.
Suppliers Supplier master records; kept aligned with an ERP vendor master and onboarding tools, synced two-way on the /suppliers resource. Local and State Taxes Two-way via Create/Update/Delete Local Tax and Upsert Primary / Non-Primary State Tax; Get by tax code and Get All for reads. Suppliers is specific to Coupa and Local and State Taxes to Paylocity — each maps to any object or custom field on the other side.

How changes propagate between Coupa and Paylocity

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.

Coupa Paylocity Interval-based propagation

DetectionStacksync polls Coupa for changes on an incremental schedule, reading only records changed since the previous pass. Polling on updated-at and created-at filters (e.g.

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

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

Rate-limit considerations

  • Coupa: Coupa does not publish explicit rate limits or expose X-RateLimit/Retry-After headers; integrations page 50 records at a time and back off on 429/503 responses.
  • 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).

How the Coupa and Paylocity connectors work

Coupa

Integration surface
REST Core API (JSON or XML)
Authentication
OAuth 2.0 / OIDC via the client-credentials grant; scopes take the service.object.right form (e.g. core.accounting.read, core.accounting.write). Legacy API keys are being retired (no new keys since R34; API-key auth unsupported from R36). Access tokens last 24 hours.
Change detection
Polling on updated-at and created-at filters (e.g. updated-at[gt]=<timestamp>); Coupa has no native webhook subscriptions, though admins can configure outbound Call Out / external notifications.
Capabilities

Rate limits
Coupa does not publish explicit rate limits or expose X-RateLimit/Retry-After headers; integrations page 50 records at a time and back off on 429/503 responses.

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.
Capabilities

Rate limits
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).
