Why teams connect Microsoft 365 and SAP

Bridge the tools people work in and the system the business runs on: real-time, two-way sync between Microsoft 365 and SAP.

The ERP holds the records the business is run on, and it is rarely where day-to-day work happens. Microsoft 365 is closer to the work, and the two often need the same facts about the same people, organizations, and transactions. Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.

Stacksync syncs Planner & To Do Tasks, Users, Groups, Mail Messages in Microsoft 365 with Outbound Deliveries, Billing Documents, GL Accounts and Journal Entries, Production Orders in SAP bi-directionally and in real time, with field-level mapping and rules for which system wins on conflict. Changes made where the work happens reach the system of record within seconds, and the reverse.

Common use cases

  • Keep CRM contacts and Microsoft 365 contacts aligned in both directions.
  • Sync employee records from an HR system into Entra ID users and group memberships.
  • Publish plant-level inventory to e-commerce and planning systems on change or on schedule.
  • Replicate journal entries and billing documents to a warehouse for finance analytics without loading the ERP.

Where Microsoft 365 collects payments: transactions post through

Payment events sync into SAP as they occur, keeping the enterprise records current without manual entry.

Where SAP is the HR or people system of record

Worker and organization data from SAP stays current in Microsoft 365, so the tools people use daily reflect the org as it actually is.

Master data corrections travel

A customer, supplier, or contact detail corrected in either system updates the other, ending duplicate maintenance.
