Retailer has the functionality to allow you to discount the cost price of individual items on a supplier invoice or the entire supplier invoice. This makes it much easier to apply one-time discounts from suppliers, enabling you to better calculate your GP.
Enabling Supplier Invoice Discounts
- From the main screen of Retailer, go to Setup -> System -> Other.
- Tick the box Allow discounts in Invoice Arrivals.
- Restart Retailer.
This enables a tick-box in Invoice Arrivals for allowing discounts, called Enable Discounting.
Enabling Supplier Invoice Discounts by Supplier (Optional)
You can set the supplier invoice discount to be enabled by default for a supplier so that it is always active when invoices from that specific supplier are arrived.
- From the main screen of Retailer, go to Stock -> Suppliers & Departments -> Suppliers
- Click the magnifying glass at the bottom and search for the supplier you are setting up.
- Click on the Other tab.
- Tick the Enable discounting by default for this Supplier tick-box.
- Click Save.

Note: The original cost price will only be remembered and used on future orders and invoice arrivals if the supplier is set to Use Last Arrival Stock Cost Price. This can be found in the Supplier screen, in the Other tab, on the right under 'When creating orders and arriving stock...'
Applying Supplier Invoice Discount on an Entire Invoice
- From the main screen of Retailer, go to Stock -> Invoice Arrivals.
- Select the supplier invoice you wish to apply the discount to, or create a new invoice arrival.
- Make sure the Enable Discounting box is ticked, near the top of the page below order number.
- Enter the discount into the discount box just below. A discount entered here will apply to the whole invoice. Press [F6] to change between a percentage and amount discount.
- Click apply then choose between applying or removing the discount.

This can be done before or after the invoice is entered.
Applying Supplier Invoice Discount on a Single Item
- From the main screen of Retailer, go to Stock -> Invoice Arrivals.
- Create a new invoice arrival, or select an invoice to edit from a supplier.
- Make sure the Enable Discounting box is ticked.
- Arrive an item as normal.
- Enter the quantity recieved.
- Enter the supplier discount in either the Discount % or Discount $ fields.
- Continue arriving the item as normal.

Supplier Invoice Discounts only affect the cost price of items arrived through the Invoice Arrivals facility and does not interact with normal discounting of stock items to customers. For normal sell price discounts, check out our Allow An Item To Be Discounted and Applying Discounts at Point of Sale instead.
