1. Avalara Base Handles Tax Calculation
   • The core Avalara plugin sends address and order data to Avalara for tax estimation.
2. Extension Enhances Communication
   • The extension intercepts and improves how data is structured and sent to Avalara.
   • Additional error-handling logic helps prevent failed requests.
3. Improved Logs & Feedback
   • If a tax validation fails, the extension adds clearer error messages to Shopware’s backend.
   • Developers and store managers can easily locate and debug issues.
4. Address Validation Enhancements
   • The extension ensures that customer address data is formatted correctly.
   • In case of missing or inconsistent fields, it attempts a graceful fallback.

• Always keep the base Avalara plugin up to date to benefit from ongoing support and updates.
• Use staging environments to test plugin changes before deploying to production.
• Ensure customer data is clean—valid postal codes and addresses improve tax accuracy.
• Clear Shopware cache after activating or updating the plugin.

• Plugin not working?
  • Ensure the base Avalara plugin is installed and activated first.
• Still seeing broken tax calculations?
  • Check Shopware logs and Avalara logs for clues.
  • Confirm address data is complete and valid.
• Errors in checkout or backend?
  • Check for conflicts with other third-party plugins that modify checkout or address handling.
• No plugin settings available?

• Can I use this plugin without the Avalara plugin?
  No. This extension depends on the official Avalara plugin.
• Does this override Avalara functionality?
  It enhances specific areas like error handling, API robustness, and logging, but does not replace the Avalara core logic.
• Can I disable the extension without disabling Avalara?
  Yes. The extension is modular and can be deactivated independently, although enhanced features will no longer apply.
