Why teams connect Odoo and SAP S/4HANA

Two ERPs, one set of facts: Stacksync keeps Odoo and SAP S/4HANA consistent in real time, whether they split the business or one is replacing the other.

Companies run two ERPs for structural reasons: a two-tier setup with subsidiaries on lighter systems, an acquisition that brought its own stack, a split by function or region, or a migration that will take quarters. In all of these, some of the same organizations, people, and transactions exist in both systems, and keeping them aligned by hand is a standing tax on the back office.

Stacksync syncs Purchase Orders (purchase.order), Inventory Transfers (stock.picking), Employees (hr.employee), Projects and Tasks (project.project / project.task) in Odoo with Customer / Supplier Roles, Production Orders, Business Partners, Sales Orders in SAP S/4HANA bi-directionally and in real time, with field-level mapping across the two data models and conflict rules you define. A record changed in either system is reflected in the other within seconds, not at the next interface run.

Common use cases

  • Sync employee records from an HR system of record into Odoo for expense and timesheet workflows.
  • Sync Odoo contacts and CRM leads with an external CRM when sales runs outside Odoo but invoicing stays in it.
  • Keep supplier records aligned between S/4HANA procurement and third-party spend platforms.
  • Push closed-won CRM opportunities into S/4HANA as sales orders without manual re-keying.

Migration in parallel

When one system is replacing the other, run both fully live during the transition and cut over without a data freeze.

Shared master data

Where both systems keep records of the same customers, suppliers, or organizations, a correction in either updates the other.

Split by function

Where one system is the people or finance suite and the other runs operations, the records both sides depend on, such as organizations, cost centers, and reference data, stay in agreement.

What you can sync between Odoo 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.

Odoo objects SAP S/4HANA objects
Projects and Tasks (project.project / project.task) Work items synced with external project tools. Billing Documents (Invoices) Invoice data pushed to CRMs and payment or collections tools for finance visibility.
Contacts (res.partner) The unified person/company record used across sales, invoicing, and purchasing; the anchor for CRM syncs. Deliveries Outbound delivery status synced to customer-facing systems for order tracking.
Sales Orders (sale.order) Quotations and confirmed orders synced with e-commerce and external CRMs. Journal Entries Financial postings read into warehouses and consolidation tools for reporting.
Invoices (account.move) Customer invoices and journal entries synced with accounting and reporting tools. Customer / Supplier Roles Role-specific views of Business Partners mapped to CRM account types.
Products (product.template / product.product) Catalog and variant data distributed to storefronts and quoting tools. Production Orders Manufacturing order status surfaced in planning and operations tools.
CRM Leads (crm.lead) Leads and opportunities synced with marketing and enrichment systems. Business Partners Unified customer and supplier master records, the anchor entity for CRM-to-ERP account syncs.
