Why teams connect Plex ERP and Resend

Bridge the tools people work in and the system the business runs on: real-time, two-way sync between Resend and Plex ERP.

The ERP holds the records the business is run on, and it is rarely where day-to-day work happens. Resend is closer to the work, and the two often need the same facts about the same people, organizations, and transactions. Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.

Stacksync syncs Contacts, Audiences, Broadcasts, Domains in Resend with Parts, Inventory, Production jobs, Sales orders in Plex ERP bi-directionally and in real time, with field-level mapping and rules for which system wins on conflict. Changes made where the work happens reach the system of record within seconds, and the reverse.

Common use cases

  • Feed open and click events into a warehouse for engagement analytics alongside product data.
  • Sync CRM contact segments into Resend Audiences so lifecycle broadcasts target current data.
  • 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 Resend faces customers and Plex ERP carries account records

Order, invoice, or account status from Plex ERP appears alongside the customer in Resend, so front-line teams answer from live data.

Where Plex ERP is the HR or people system of record

Worker and organization data from Plex ERP stays current in Resend, so the tools people use daily reflect the org as it actually is.

Master data corrections travel

A customer, supplier, or contact detail corrected in either system updates the other, ending duplicate maintenance.
