Why teams connect Amazon Seller Central and Kustomer

Flow Amazon Seller Central data into Kustomer 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 Kustomer, so Kustomer always reflects the current state of Amazon Seller Central — without exports, scripts, or schedulers.

The CRM is supposed to be the record of every customer relationship, but customer-relevant information also accumulates in the other tools a team runs. Whatever Amazon Seller Central holds or produces that touches a customer, whether conversations, payments, replies, enriched data, or notes, the CRM only benefits if it arrives without someone copying it over.

Common use cases

  • Land Amazon orders, reports, and settlement data in your warehouse or ERP as they are produced.
  • Track price and inventory report changes across marketplaces from one queryable table.
  • Sync customers bi-directionally with the CRM and ERP so agents see deal, billing, and subscription context on the timeline
  • Push order and shipment records from commerce systems into Kustomer custom objects so agents answer order-status questions without switching tools

Enriched fields land directly on records in Kustomer, and refreshes keep them from going stale.

Where Amazon Seller Central processes payments

Where Amazon Seller Central can store CRM context: fields kept current

Owner, lifecycle stage, or account details from Kustomer sync into Amazon Seller Central, so people working there have the context without switching tools.
