Why teams connect Plex ERP and Shopify

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

Shopify 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 Abandoned Checkouts, Products, ProductMedias, ProductVariants in Shopify 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

  • Sync orders, customers, and inventory into Postgres for operational reporting across stores.
  • Keep customer records aligned between Shopify and a CRM for segmentation and lifetime-value analysis.
  • Mirror purchase orders and receipts to accounting or planning tools.
  • Feed quality and scrap data to dashboards supervisors check without logging into Plex.

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

A deal won in Shopify 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 Shopify, 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.
