How to add a discount
1. Go to tab Invoices.
2. Click Create invoice.
3. On the right panel Invoicing settings click on Discount.
4. You can now customise the discount in the right panel. Simply click on the drop-down menu below Discount settings. Choose first whether you want to base the discount on the invoice total or on individual invoice lines (hence per product/service).
Once you’ve decided on which amount you want to add the discount, please select the discount type (a percentage or an amount in euros) and whether the discount should include or exclude the VAT (Discount calculation).
By unit price:
VAT = 20% (0,2)
Discount percentage = 10% / Total Discount = 20€
Unit Price = 100€
Quantity = 1
How is the discount calculated for total DISCOUNT AMOUNT, INcluding VAT?
(Unit Price * Quantity) * (1+VAT) - Total Discount
(100 * 1) * (1 + 0,2) – 20 = 100
How is the discount calculated for DISCOUNT PERCENTAGE, INcluding VAT?
(Unit Price * Quantity) * (1 + VAT) * (1 - (Discount Percentage/100))
(100 * 1) * (1 + 0,2) * (1 - (10 / 100)) = 108
How is the discount calculated for total DISCOUNT AMOUNT, EXcluding VAT?
((Unit Price * Quantity) – Total Discount) * (1 + VAT)
((100 * 1) – 20) * (1,2) = 96
How is the discount calculated for DISCOUNT PERCENTAGE, EXcluding VAT?
(Unit Price * Quantity) * (1-(Discount Percentage/100)) * (1 + VAT)
(100 * 1) * (1 - (10 / 100)) * (1 + 0,2) = 108
