Why teams connect Epicor ERP and Kustomer

Close the gap between front office and back office: Kustomer and Epicor ERP share customers and status in real time, in both directions.

Kustomer holds the customer relationship; Epicor ERP runs the operations and records behind the business. The two overlap wherever the same organizations and transactions matter to both, and when that overlap is bridged by re-keying or overnight batch, each side spends the day working from stale data.

Stacksync syncs Tags, Notes, Customers, Conversations in Kustomer with Customers, Suppliers, Parts, Sales orders in Epicor ERP field by field, in real time, and in both directions. You decide which system owns which fields; Stacksync keeps every copy consistent and resolves conflicts by rules you set.

Common use cases

  • Push order and shipment records from commerce systems into Kustomer custom objects so agents answer order-status questions without switching tools
  • Mirror conversations and satisfaction data into a warehouse for support analytics and agent performance reporting
  • Sync Epicor customers and AR invoices into a CRM so sales sees order history and credit status without ERP logins.
  • Push won opportunities from the CRM into Epicor as sales orders and sync order status back.

Where Epicor ERP handles order-to-cash: closed-won flows through

A deal won in Kustomer creates or updates the customer in Epicor ERP with clean data, so fulfillment and invoicing start without re-entry.

Where Epicor ERP is the finance system of record: money status on the account

Invoice and payment state from Epicor ERP shows on the account in Kustomer, so reps see balances before promising the next order.

One customer master

Where both systems keep customer or organization records, corrections in either propagate to the other, ending dual maintenance.

What you can sync between Epicor ERP and Kustomer

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.
