A customer buys a product for $300, and you want to apply a manual discount of $1.20 (instead of using percentage-based discounts).
Customer Order:
The customer purchases one unit of Product A for $300.
You want to give a manual discount of $1.20 as a price adjustment.
Invoice Entry:
Add Product A to the invoice with:
Quantity: 1
Price: $300
Taxes: 15%
Instead of applying a discount percentage, you add a separate line for the discount:
Product: Manual Discount (or any dummy product you use for discounts).
Quantity: -1 (negative because it reduces the total).
Price: $1.20.
Taxes: 15% (so that tax calculations remain consistent).
Invoice Calculation:
Untaxed Amount: $298.80 (300 - 1.20).
Tax (15%): $44.82.
Total Amount: $343.62.
