Why teams connect Amazon Seller Central and Plex ERP

Flow Amazon Seller Central data into Plex ERP in real time — no exports, no schedulers, no custom scripts.

Amazon Seller Central is a read-only source: Stacksync reads its data in real time and delivers it into Plex ERP, so Plex ERP always reflects the current state of Amazon Seller Central — without exports, scripts, or schedulers.

The ERP holds the records the business is run on, and it is rarely where day-to-day work happens. Amazon Seller Central 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 Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.

Common use cases

  • 01 Track price and inventory report changes across marketplaces from one queryable table.
  • 02 Land Amazon orders, reports, and settlement data in your warehouse or ERP as they are produced.
  • 03 Keep customers, parts, and pricing aligned between Plex and the CRM the sales team uses.
  • 04 Push sales orders captured in e-commerce or EDI systems into Plex for scheduling and fulfillment.
