# Intuit Enterprise Suite — Accounting API: overview > Canonical URL: https://developers.apideck.com/apis/accounting/intuit-enterprise-suite/overview Intuit Enterprise Suite (IES) is a scalable ERP system, integrated multi-entity platform designed to enhance productivity and profitability for clients with complex needs. - Status: live - Authentication: oauth2 - **account type required:** Active Intuit Enterprise Suite subscription - **apideck credentials available:** false - **apideck credentials note:** You register your own Intuit Developer app and supply its Client ID and Secret. - **authentication note:** Authorization Code flow. Custom scopes supported. - **consumer access level:** Any user with Intuit Enterprise Suite access can authorize (Admin recommended for full data access) - **costs:** Free at the Builder tier (500,000 CorePlus read calls/month); paid tiers from $300/month (Silver) to $1,700/month (Gold) for higher volumes. - **difficulty:** moderate - **difficulty reason:** Self-Service Signup + App Review Required - **environment notes:** - **description:** 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. - **environment:** Sandbox - **description:** Live consumer data. Credentials: production keys, issued only after App Assessment approval. **Development credentials CANNOT be used with production accounts**, and vice versa. - **environment:** Production - **important to know:** 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 it are blocked, not throttled, until next cycle or upgrade — and Silver+ is required for the IES-exclusive Dimensions API (GraphQL). Platform Service Fees bill to your own Intuit app, not to Apideck. Intuit sometimes errors on healthy connections: a SystemFault, a company lockout (codes 100/140, LOCKED_BY_SERVER), a 403 AuthorizationFault or a 400 Permission Denied (code 5020). Apideck treats these as transient and keeps the connection valid. Retry after a backoff. - **partnership note:** Free, self-service signup; an App Assessment Questionnaire must be approved before Intuit issues production credentials. - **partnership portal name:** Intuit Developer Account - **partnership required:** true - **partnership url:** https://developer.intuit.com/app/developer/homepage - **rate limits:** 500 requests/minute per company (realm), 10 concurrent per second; batch 120/minute (30 operations max). Paid tiers do not raise these limits. - **responsibility matrix:** - **area:** Create Intuit Developer Account - **customer:** ✓ - **apideck:** Docs provided - **area:** Register & Configure App - **customer:** ✓ -
