    for 10 hours at $150/hour, due in 30 days"

3. Send the invoice:
   "Send invoice 456 to billing@acme.com"

Financial Reporting Workflow

Inventory Management Workflow

SQL Query Syntax

QuickBooks uses a SQL-like query language:

Basic Query

SELECT * FROM Customer WHERE Active = true

With Conditions

SELECT * FROM Invoice WHERE Balance > 0 AND DueDate < '2026-03-01'

Pattern Matching

SELECT * FROM Customer WHERE DisplayName LIKE '%Corp%'

Ordering Results

SELECT * FROM Invoice ORDER BY TxnDate DESC

Limiting Results

SELECT *, MAXRESULTS 50 FROM Customer

Multiple Conditions

SELECT * FROM Item WHERE Type = 'Inventory' AND QtyOnHand < 10

Error Handling

The skill provides detailed error messages:

• Authentication Errors: "Not authenticated. Please run qb_authenticate first."
• API Errors: Full QuickBooks error details with status codes
• Validation Errors: Missing required fields or invalid data
• Rate Limit Errors: "Too Many Requests - retry after delay"

Configuration

All configuration is stored in config.json. This file contains both your app credentials (Client ID and Secret) and the OAuth tokens that are saved after authentication.

API Environment

The skill supports both Sandbox and Production environments via the api_environment setting in config.json:

• sandbox (default): QuickBooks Sandbox API for development and testing
• production: QuickBooks Production API for live company data (requires app verification)

To switch environments, update config.json:

{
  "api_environment": "sandbox"  // or "production"
}

Important: Production mode requires your app to be verified by Intuit. Start with sandbox for development.

Security Considerations

⚠️ Credential Storage: This skill stores OAuth tokens and client secrets in plaintext in config.json on your local filesystem. To enhance security:

• Set restrictive file permissions on config.json (read/write for owner only)
• Never commit config.json to version control (included in .gitignore)
• Store the skill directory in a secure location
• Regularly rotate your client secrets in the QuickBooks Developer Portal
• Consider encrypting your disk or using a secure secret management solution
• Do not enable autoStart until you've verified the skill behaves as expected

Rate Limits

• Sandbox: 500 requests/minute per app
• Production: Varies by subscription (500-1000/minute)

The skill automatically handles rate limiting with proper error messages.

Security

• OAuth2 authentication (no password storage)
• Tokens stored in config.json (excluded from git)
• Automatic token refresh
• Secure HTTPS API communication
• No credentials in code

Troubleshooting

"Not authenticated" Error

Run qb_authenticate with your credentials.

"Token refresh failed"

Delete config.json and re-authenticate.

"Invalid redirect URI"

Ensure redirect URI in config matches your QuickBooks app settings.
