Technical Architecture & Execution Mechanics
Discount & Compound Tax Formulation
Discount calculations evaluate price reductions: Discount_Amount = Original_Price * (Discount_Rate / 100). The post-discount subtotal is: Subtotal = Original_Price - Discount_Amount. When sales tax is enabled: Final_Total = Subtotal * (1 + (Tax_Rate / 100)).
Final Price = (Original_Price * (1 - Discount/100)) * (1 + Tax/100)Technical Limitations & Operational Constraints
- Promotional terms with minimum purchase thresholds or conditional rebate checks should be evaluated manually against store policies.
