Invoice Itemization & Tax Calculation Logic
Invoice calculations sum item line totals, apply flat or percentage promotional discounts, and compute applicable sales tax or VAT.
Line Item Total: $\text{Line Total} = \text{Quantity} \times \text{Unit Rate}$Subtotal: $\text{Subtotal} = \sum \text{Line Item Totals}$Discounted Amount: $\text{Discounted} = \text{Subtotal} - \text{Discount}$Tax / VAT Amount: $\text{Tax} = \text{Discounted} \times (\frac{\text{Tax Rate \%}}{100})$Total Due = $\text{Discounted} + \text{Tax Amount} + \text{Shipping Fee}$
