Why teams connect Acumatica and Paylocity

Sync the workers, org structure, and cost centers that Acumatica 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. Acumatica 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 Vendors, Sales Orders, Invoices, Purchase Orders in Acumatica with Earnings (Pay Setup), Local and State Taxes, Direct Deposit, Pay Statements 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 Acumatica 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 Two-way sync of customers, orders, and invoices between Acumatica and a CRM so sales sees ERP truth without ERP logins.
  • 02 Create sales orders in Acumatica from e-commerce platforms and sync shipment and tracking status back to the storefront.
  • 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

Where Paylocity is the worker system of record: one employee master

When a worker is hired, moved, or offboarded in Paylocity, the matching employee record in Acumatica is created, updated, or deactivated, so the business system reflects the workforce as it actually is.

New hires ready to transact in Acumatica

A new person set up in Paylocity becomes an employee record in Acumatica 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 Acumatica roll up to the same structure Paylocity maintains.
