Why teams connect eClinicalWorks and Linnworks
Bridge the tools people work in and the system the business runs on: real-time, two-way sync between eClinicalWorks and Linnworks.
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 Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.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 Practitioners, Observations, Medications, Allergies in eClinicalWorks with Open Orders, Processed Orders, Stock Items, Stock Levels in Linnworks 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.
- Sync orders from Linnworks into an ERP or accounting system as they are processed, without CSV exports
- Keep stock levels consistent between Linnworks and external systems so multichannel listings stay aligned with sellable stock
Master data corrections travel
A customer, supplier, or contact detail corrected in either system updates the other, ending duplicate maintenance.

FAQ
eClinicalWorks and Linnworks integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between eClinicalWorks and Linnworks: authenticate both systems, choose the objects to sync (such as eClinicalWorks's Immunizations and Documents), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
eClinicalWorks: Traditional integrations run over HL7 v2 interfaces (ADT for demographics, SIU for scheduling, ORU for results), which are push-based message feeds rather than request/response APIs. Linnworks: The Linnworks API uses a token-exchange model: application credentials plus a per-account install token are exchanged for a session token that authorizes subsequent calls. Stacksync's field mapping accounts for these differences between eClinicalWorks and Linnworks without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means eClinicalWorks and Linnworks records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed eClinicalWorks and Linnworks connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom eClinicalWorks–Linnworks integration in-house.
-
Yes — Stacksync ships production-grade connectors for both eClinicalWorks and Linnworks. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on eClinicalWorks: HL7 interface feeds push event messages as they occur; the FHIR API is polled. On Linnworks: Polling on order and stock endpoints. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
