Why teams connect eClinicalWorks and SAP S/4HANA

Bridge the tools people work in and the system the business runs on: real-time, two-way sync between eClinicalWorks and SAP S/4HANA.

The ERP holds the records the business is run on, and it is rarely where day-to-day work happens. eClinicalWorks 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 Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.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 Encounters, Practitioners, Observations, Medications in eClinicalWorks with Production Orders, Business Partners, Sales Orders, Purchase Orders in SAP S/4HANA 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

  • Land encounter and billing-context data in a warehouse for utilization and revenue-cycle reporting.
  • Feed appointment events to reminder and messaging platforms to reduce no-shows.
  • Feed S/4HANA financial and logistics documents into a data warehouse for reporting without custom ABAP extracts.
  • Keep supplier records aligned between S/4HANA procurement and third-party spend platforms.

Where eClinicalWorks collects payments: transactions post through

Payment events sync into SAP S/4HANA as they occur, keeping the enterprise records current without manual entry.

Where SAP S/4HANA is the HR or people system of record

Worker and organization data from SAP S/4HANA stays current in eClinicalWorks, 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.
