Why teams connect Coupa and eClinicalWorks

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

Coupa 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 Users, Accounts, Contracts, Expense Reports in Coupa and Observations, Medications, Allergies, Immunizations in eClinicalWorks in sync, bi-directionally and in real time. Whatever records eClinicalWorks keeps and whatever events it produces, the overlap with Coupa 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 Provision and update Users in Coupa from an HRIS or identity provider as employees join, change roles, or leave.
  • 02 Mirror Purchase Orders and their status into an operational Postgres database for spend reporting and three-way match analytics.
  • 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 handles customer conversations: billing context in view

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

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

Payment and charge activity flows into Coupa 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.

What you can sync between Coupa and eClinicalWorks

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.

Coupa objects eClinicalWorks objects How this pairing syncs
Users Employee and user accounts with roles and content groups; provisioned and updated from an HRIS or identity provider. Documents Clinical notes and attachments referenced from the chart. Users is specific to Coupa and Documents to eClinicalWorks — each maps to any object or custom field on the other side.
Accounts Chart-of-accounts segments and GL codes; usually mastered in the ERP and written into Coupa so requisitions and invoices code correctly. Diagnostic reports Structured result reports grouping observations for a study or panel. Accounts is specific to Coupa and Diagnostic reports to eClinicalWorks — each maps to any object or custom field on the other side.
Contracts Supplier contract records with terms and dates; read out for reporting or created from a CLM system. Patients Demographic records exposed via FHIR Patient resources and HL7 ADT feeds; the anchor for all clinical syncs. Contracts is specific to Coupa and Patients to eClinicalWorks — each maps to any object or custom field on the other side.
Expense Reports Employee expense reports and their lines; exported to AP or ERP for reimbursement and GL posting. Appointments Scheduling records available via FHIR and HL7 SIU messages, synced for reminders and outreach. Expense Reports is specific to Coupa and Appointments to eClinicalWorks — each maps to any object or custom field on the other side.
Requisitions Employee purchase requests with lines and approval chains; read out to warehouses, or created via the API from upstream intake tools. Encounters Visit records tying diagnoses, providers, and billing context together. Requisitions is specific to Coupa and Encounters to eClinicalWorks — each maps to any object or custom field on the other side.
Purchase Orders PO headers and lines; synced two-way with ERPs so orders raised in Coupa flow to the ledger and status updates flow back on the /purchase_orders resource. Practitioners Provider records used to keep directories and scheduling systems consistent. Purchase Orders is specific to Coupa and Practitioners to eClinicalWorks — each maps to any object or custom field on the other side.

How changes propagate between Coupa and eClinicalWorks

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.

DetectionStacksync polls Coupa for changes on an incremental schedule, reading only records changed since the previous pass. Polling on updated-at and created-at filters (e.g.

Rate-limit considerations

  • Coupa: Coupa does not publish explicit rate limits or expose X-RateLimit/Retry-After headers; integrations page 50 records at a time and back off on 429/503 responses.
  • eClinicalWorks: Subject to the platform's API rate limits and interface throughput agreements.
