Line discounts on a cash purchase
Apply a discount to individual line items when buying goods.
Jul 11, 2026
What this does
A line discount reduces the price of a single item in your cash purchase. This is useful when a supplier offers a special price on a particular product or quantity. The discount is deducted from that line's subtotal before taxes and document-level discounts are applied.
Before you start
- You have the ability to create cash purchases in your Usystems permission group.
- Know the discount amount or percentage you want to apply.
- The item must already be added to the cash purchase form.
Steps
- Open the cash purchase form. Navigate to Purchases → New Cash Purchase Open in Usystems.
- Add the items you are purchasing in the Line Items section by selecting a product and entering a quantity.
- Locate the item line where you want to apply the discount.
- In the Discount field on that line (if visible), enter either a percentage (e.g., 10%) or an absolute amount (e.g., 100 AFN).
- The system recalculates the line subtotal and the invoice total automatically.
- Complete the rest of the cash purchase form (payment account, currency, etc.) and save.
Accounting impact
When you apply a line discount:
- The Cost of Goods Purchased (or relevant inventory account) is debited for the discounted amount, not the original price.
- The Accounts Payable (or Cash if paying immediately) is credited for the discounted total.
- No separate discount account is used; the reduction flows directly into the purchase cost.
Tips & common mistakes
- Discount vs. unit price: A line discount is separate from the item's base unit price. Use the discount field only if the supplier offered a special reduction; do not use it to enter a custom unit price.
- Order of calculation: Line discounts are applied first (reducing each line), then document-level discounts, then taxes. Plan your discounts accordingly.
- Negative discount: If you enter a negative value, the system treats it as a surcharge (price increase).
- Percentage vs. amount: Use whichever is clearer for your deal. The system accepts both.
