The taxCode in the current order processing logic is hardcoded to "AVATAX". This implementation does not allow flexibility for scenarios where different tax codes may be required based on product types or specific business rules.

Context:

1. Hardcoded Implementation:

   • The tax code is explicitly set to "AVATAX" without any conditional checks:

     processedOrderMap.put("taxCode", "AVATAX")
     

2. Other Business Scenarios:

   • Certain product types, such as Digital Goods, may require different tax codes (e.g., "-Not Taxable-").
   • New business rules or product-specific requirements could demand dynamic tax code assignment.

Problem:

• Inflexibility: The hardcoded tax code "AVATAX" cannot handle cases where a different tax code is required.
• Scalability Issues: Any future changes to tax code requirements will necessitate code modifications, increasing maintenance efforts and risks.
• Non-Compliant Outputs: Scenarios like Digital Goods may result in incorrect tax code assignments due to the lack of dynamic handling.

Expected Behavior:

• The taxCode should be determined dynamically based on factors such as:
  • Product type (e.g., Digital Goods vs. physical goods).
  • Other business-defined criteria.
