Sandbox: Development and testing with sample data. Credentials: development keys from the Intuit Developer Portal (https://developer.intuit.com/app/developer/dashboard). Access: QuickBooks Online sandbox companies for core API testing, plus a dedicated single-entity Intuit Enterprise Suite sandbox created from the portal. Limitations: US-only; valid for 2 years, then recreated (sample data cannot be reset in place, and data cannot be imported or exported); 10 sandboxes maximum per developer account; QuickBooks Online sandboxes exclude IES-specific features such as multi-entity. Sandbox calls are never metered.
Production: Live consumer data. Credentials: production keys, issued only after App Assessment approval. **Development credentials CANNOT be used with production accounts**, and vice versa.

Intuit Enterprise Suite shares its API, developer program, and OAuth client with QuickBooks Online — an existing QuickBooks integration on Apideck works with IES on the same production credentials with no code changes, and migration between the two connectors is supported.
Each entity in a multi-entity IES organization needs its own OAuth connection (one connection = one company realm), and the API supports no cross-entity transactions or intercompany postings.
Refresh tokens expire after 100 days of inactivity and, under Intuit's November 2025 policy, have a hard 5-year maximum lifetime regardless of activity (standard accounting scopes from October 2028; granular scopes from February 2027) — the consumer must then re-authorize.
The free Builder tier's CorePlus (read) cap is hard: calls above the monthly volume are blocked, not throttled, until the next billing cycle or a tier upgrade. Because the connector uses your own Intuit app, Intuit's Platform Service Fees bill to you, not to Apideck.
The IES-exclusive Dimensions API (GraphQL) is gated behind the paid Silver tier or higher — the free Builder tier has no access.
