Why teams connect Kustomer and SAP

Close the gap between front office and back office: Kustomer and SAP share customers and status in real time, in both directions.

Kustomer holds the customer relationship; SAP 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 Conversations, Messages, Companies, Custom Objects (Klasses) in Kustomer with Business Partners, Materials (Products), Sales Orders, Purchase Orders in SAP 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 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
  • Expose sales order and delivery status to customer portals through a synced Postgres database instead of direct SAP access.
  • Publish plant-level inventory to e-commerce and planning systems on change or on schedule.

Where SAP manages people and org data: keep Kustomer aligned

Owners, territories, and org structure informed by SAP stay current in Kustomer.

Where SAP handles order-to-cash: closed-won flows through

A deal won in Kustomer creates or updates the customer in SAP with clean data, so fulfillment and invoicing start without re-entry.

Where SAP is the finance system of record: money status on the account

Invoice and payment state from SAP shows on the account in Kustomer, so reps see balances before promising the next order.

What you can sync between Kustomer and SAP

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Kustomer objects SAP objects
Teams Team assignments support routing parity and reporting. Inventory / Stock Plant and storage-location quantities synced to storefronts and planning tools.
Tags Labels on conversations and customers sync for categorization and analytics. Cost Centers Controlling masters read for mapping costs in finance integrations.
Notes Internal annotations carry context alongside synced conversations. Business Partners The unified customer and supplier master in S/4HANA, the anchor object for CRM and procurement syncs.

Conversations Support threads across channels sync outward for analytics and CRM context. Sales Orders Order documents written from external channels and read for status and fulfillment.
Messages Individual messages within conversations support full-thread replication. Purchase Orders Procurement documents synced with supplier portals and spend tools.
