Why teams connect Salesforce and SAP S/4HANA

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

Salesforce 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 Contacts, Leads, Opportunities, Cases in Salesforce with Business Partners, Sales Orders, Purchase Orders, Products / Materials 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

  • Sync Accounts, Contacts, and Opportunities bi-directionally with Postgres so engineering teams read and write CRM data with plain SQL.
  • Write product usage metrics computed in a warehouse onto Account and Contact fields so reps see adoption signals on the record.
  • 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 handles order-to-cash: closed-won flows through

A deal won in Salesforce 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 Salesforce, so reps see balances before promising the next order.

One customer master

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

What you can sync between Salesforce 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.

Salesforce objects SAP S/4HANA objects
Leads Unqualified prospects; often written into Salesforce from enrichment or product-signup pipelines. Sales Orders Order headers and line items synced to CRMs and fulfillment systems as they are created or amended.
Opportunities Deal records with stage and amount; synced to databases for pipeline reporting and to ERPs at close. Purchase Orders Procurement documents shared with supplier portals and spend-management tools.
Cases Support records; synced with help desk tools or internal databases for escalation workflows. Products / Materials Material master data distributed to e-commerce, PIM, and CRM catalogs.
Campaigns Marketing membership data; read out for attribution analysis in the warehouse. Billing Documents (Invoices) Invoice data pushed to CRMs and payment or collections tools for finance visibility.
Tasks and Events Activity records; usually read-only in syncs to feed activity reporting. Deliveries Outbound delivery status synced to customer-facing systems for order tracking.
Products and Price Books Catalog and pricing data; commonly mastered in an ERP and written into Salesforce. Journal Entries Financial postings read into warehouses and consolidation tools for reporting.
