Why teams connect Attio and Plex ERP

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

Attio 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 Workspaces, Custom objects, People, Companies in Attio with Customers, Suppliers, Shipments, Quality records 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

  • Keep Attio aligned with a billing system or ERP on customer records and plan status.
  • Mirror lists and list entries into a database for pipeline reporting beyond the in-app views.
  • Keep customers, parts, and pricing aligned between Plex and the CRM the sales team uses.
  • Push sales orders captured in e-commerce or EDI systems into Plex for scheduling and fulfillment.

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

A deal won in Attio 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 Attio, 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.
