Why teams connect Intercom and Plex ERP

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

Intercom holds the customer relationship; Plex 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 Admins & Teams, Articles, Contacts, Companies in Intercom with Sales orders, Purchase orders, Customers, Suppliers in Plex 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

  • Route qualified leads from Intercom conversations into the CRM as leads or opportunities in near real time
  • Sync contacts and companies bi-directionally with the CRM so support sees deal context and sales sees conversation history
  • Push sales orders captured in e-commerce or EDI systems into Plex for scheduling and fulfillment.
  • Mirror purchase orders and receipts to accounting or planning tools.

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

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

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

Invoice and payment state from Plex ERP shows on the account in Intercom, 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.
