Manual discounts will apply the discounted price when you click the Apply Discount button to an eligible customer’s invoice.
To first set up, go to Settings > Invoice Options > Discounts and select Manual followed by clicking Save Settings.
To set up your customer’s discount rate, go to Customers > Select the customer > Options tab > Enter in the discount rate that this customer should get and use the tick box to decide if the discount should be shown on the invoice > Click Update.
Applying the Discount
To apply a discount to a customers invoice, generate an invoice for the customer as normal. You can then press the Apply Discount option that will subtract the percentage due against the total net amount and show as a negative line.
Please note that if you only wanted to discount certain items you should enter those first, then apply the discount, then add the subsequent line items. You can only use the Apply Discount button once on an invoice.
If a discount is entered incorrectly against an invoice, you can delete the line item. The Apply Discount button will then become available again.
