Data export & off-boarding SLA
Demand this clausePlain English: You must be able to leave with all of your data, in an open format, within a defined number of days, at a defined cost (ideally zero).
Suggested language
"Upon termination or upon Customer request, Vendor shall provide, at no additional cost, a complete export of Customer Data in a commercially reasonable, machine-readable format (CSV, JSON, HL7, FHIR, or PDF as applicable), within thirty (30) days of request. Customer Data includes all clinical records, financial data, audit logs, appointment history, and metadata created by or on behalf of Customer."
Vendor pushback
"Our standard export is PDF only" or "That's a professional-services engagement."
If they refuse
This is the single strongest signal that a vendor plans to trap you. If they refuse, walk. No vendor lock-in is worth this risk.
Legal review note: Confirm 'Customer Data' is defined broadly enough to include derivative data (analytics, audit logs).
