Why teams connect Kustomer and SAP S/4HANA
Close the gap between front office and back office: Kustomer and SAP S/4HANA share customers and status in real time, in both directions.
Kustomer holds the customer relationship; SAP S/4HANA 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 Notes, Customers, Conversations, Messages in Kustomer with Deliveries, Journal Entries, Customer / Supplier Roles, Production Orders in SAP S/4HANA 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
- Mirror conversations and satisfaction data into a warehouse for support analytics and agent performance reporting
- Keep customer attributes updated from billing systems so routing rules and SLAs reflect account value
- Surface invoice and payment status from S/4HANA inside the CRM so account teams see open balances.
- Replicate material master and pricing data to e-commerce and quoting tools.
Where SAP S/4HANA manages people and org data: keep Kustomer aligned
Owners, territories, and org structure informed by SAP S/4HANA stay current in Kustomer.
Where SAP S/4HANA handles order-to-cash: closed-won flows through
A deal won in Kustomer creates or updates the customer in SAP S/4HANA with clean data, so fulfillment and invoicing start without re-entry.
Where SAP S/4HANA is the finance system of record: money status on the account
Invoice and payment state from SAP S/4HANA shows on the account in Kustomer, so reps see balances before promising the next order.
What you can sync between Kustomer and SAP S/4HANA
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 S/4HANA objects | |
|---|---|---|
| Users Agent records map conversation ownership to people in other systems. | Purchase Orders Procurement documents shared with supplier portals and spend-management tools. | |
| Teams Team assignments support routing parity and reporting. | Products / Materials Material master data distributed to e-commerce, PIM, and CRM catalogs. | |

FAQ
Kustomer and SAP S/4HANA integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Kustomer and SAP S/4HANA: authenticate both systems, choose the objects to sync (such as Kustomer's Users and Teams), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.

Common patterns for Kustomer and SAP S/4HANA: Where SAP S/4HANA manages people and org data: keep Kustomer aligned; Where SAP S/4HANA handles order-to-cash: closed-won flows through; Where SAP S/4HANA is the finance system of record: money status on the account.

Kustomer: REST API. Authentication: API key used as a bearer token, scoped by role. SAP S/4HANA: OData REST APIs (v2/v4), with SOAP, BAPI/RFC, and IDoc interfaces on on-premise editions. Authentication: OAuth 2.0 with communication arrangements on cloud editions; basic auth or certificate-based on-premise. Stacksync manages authentication, retries, and rate limits on both sides.
-
Kustomer: Custom object types are called Klasses, and they are the standard mechanism for landing external data like orders and subscriptions where agents work. SAP S/4HANA: The Business Partner model consolidates what older SAP systems split into separate customer and vendor masters. Stacksync's field mapping accounts for these differences between Kustomer and SAP S/4HANA without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Kustomer and SAP S/4HANA records are not retained after a sync operation.
