Why teams connect eClinicalWorks and Zuora

Connect the financial records in Zuora with the work happening in eClinicalWorks, so both stay current without exports or copy-paste.

Zuora holds the financial truth: who the customers are, what they were billed, what they paid. eClinicalWorks is where part of the day-to-day work happens, and that work often involves the same customers and transactions. Without a live connection, the two drift apart, and people end up answering questions from stale copies.

Stacksync keeps Payment, Usage, Order and Amendment, Account (Billing Account) in Zuora and Diagnostic reports, Patients, Appointments, Encounters in eClinicalWorks in sync, bi-directionally and in real time. Whatever records eClinicalWorks keeps and whatever events it produces, the overlap with Zuora is mapped field by field, and a change on either side shows up on the other within seconds.

There is no middleware to build, no API rate limits to babysit, and no nightly job that leaves the morning running on yesterday's data.

Common use cases

  • 01 Stream metered Usage records from a warehouse or metering pipeline into Zuora so consumption-based charges are rated on the correct Rate Plan.
  • 02 Two-way sync of Accounts and Subscriptions with an operational Postgres database so product and finance teams read billing state in SQL while changes flow back into Zuora.
  • 03 Push referral or intake data captured in external forms into the EHR via HL7 interfaces.
  • 04 Sync patient demographics and appointments into a CRM so patient outreach and intake teams work from current data.

Common sync patterns

Where eClinicalWorks collects payments or triggers charges: events land in Zuora

Payment and charge activity flows into Zuora as it happens, so the books reflect reality without manual reconciliation.

Where eClinicalWorks tracks people or companies: one identity

A customer's details updated in either system update the other, so finance and the rest of the business stop maintaining two versions of the same customer.

Where eClinicalWorks handles customer conversations: billing context in view

Front-line teams see invoice and payment status from Zuora next to the customer they are helping, without logging into the finance system.

What you can sync between eClinicalWorks and Zuora

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.

eClinicalWorks objects Zuora objects How this pairing syncs
Diagnostic reports Structured result reports grouping observations for a study or panel. Product and Product Rate Plan (Product Catalog) The catalog of sellable products and their pricing; usually mastered elsewhere and written into Zuora, or read to map subscription charges. Diagnostic reports is specific to eClinicalWorks and Product and Product Rate Plan (Product Catalog) to Zuora — each maps to any object or custom field on the other side.
Patients Demographic records exposed via FHIR Patient resources and HL7 ADT feeds; the anchor for all clinical syncs. Invoice Billing documents generated from rate plan charges and order line items; typically read out into an ERP or GL for revenue recognition and reconciliation. Patients is specific to eClinicalWorks and Invoice to Zuora — each maps to any object or custom field on the other side.
Appointments Scheduling records available via FHIR and HL7 SIU messages, synced for reminders and outreach. Payment Payment and refund transactions applied against invoices; read for cash application, dunning, and reconciliation reporting in the warehouse. Appointments is specific to eClinicalWorks and Payment to Zuora — each maps to any object or custom field on the other side.
Encounters Visit records tying diagnoses, providers, and billing context together. Usage Metered consumption records; written into Zuora from a metering or warehouse pipeline so consumption-based charges are rated and invoiced. Encounters is specific to eClinicalWorks and Usage to Zuora — each maps to any object or custom field on the other side.
Practitioners Provider records used to keep directories and scheduling systems consistent. Order and Amendment Records of subscription create and change actions; written to Zuora to drive quote-to-cash and read for subscription change history. Practitioners is specific to eClinicalWorks and Order and Amendment to Zuora — each maps to any object or custom field on the other side.
Observations Labs and vitals, delivered via FHIR resources or HL7 ORU result messages. Account (Billing Account) The customer billing entity holding contacts, payment methods, and billing settings; synced two-way as the parent record most other Zuora objects hang off. Observations is specific to eClinicalWorks and Account (Billing Account) to Zuora — each maps to any object or custom field on the other side.

How changes propagate between eClinicalWorks and Zuora

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

eClinicalWorks Zuora Interval-based propagation

DetectionStacksync polls eClinicalWorks for changes on an incremental schedule, reading only records changed since the previous pass. HL7 interface feeds push event messages as they occur.

DeliveryEach detected change is written to Zuora through its API, with automatic retries and rate-limit backoff.

Zuora eClinicalWorks Sub-second propagation

DetectionZuora notifies Stacksync of record changes through webhook events. Incremental extraction on the indexed UpdatedDate column via ZOQL/AQuA stateful mode (high-water mark), plus Callout Notifications (webhooks) for.

DeliveryEach detected change is written to eClinicalWorks through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • eClinicalWorks: Subject to the platform's API rate limits and interface throughput agreements.
  • Zuora: Concurrency limits: 40 concurrent requests by default, 80 for Object Queries, 200 for high-volume operations (doubled for Performance Booster); HTTP 429 on breach with exponential backoff; OAuth token endpoint is not bound by the limit.
