Why teams connect SAP S/4HANA and Vtiger CRM

Close the gap between front office and back office: Vtiger CRM and SAP S/4HANA share customers and status in real time, in both directions.

Vtiger CRM 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 Cases, Products, Quotes, Sales Orders in Vtiger CRM with Production Orders, Business Partners, Sales Orders, Purchase 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

  • 01 Push Quotes and Invoices into accounting software to avoid re-keying billing data.
  • 02 Replicate pipeline data to a warehouse for RevOps reporting.
  • 03 Feed S/4HANA financial and logistics documents into a data warehouse for reporting without custom ABAP extracts.
  • 04 Keep supplier records aligned between S/4HANA procurement and third-party spend platforms.

Common sync patterns

One customer master

Where both systems keep customer or organization records, corrections in either propagate to the other, ending dual maintenance.

Where SAP S/4HANA manages people and org data: keep Vtiger CRM aligned

Owners, territories, and org structure informed by SAP S/4HANA stay current in Vtiger CRM.

Where SAP S/4HANA handles order-to-cash: closed-won flows through

A deal won in Vtiger CRM creates or updates the customer in SAP S/4HANA with clean data, so fulfillment and invoicing start without re-entry.
