Does a supplier give a payment discount, for example 2% for payment within 8 days? Set the discount on the relation. Invoyz then adds a discount line to every invoice of that relation automatically.
Set up a payment discount
- Go to Relations and open the relation.
- Open the Processing tab and find the Payment discount card.
- Enter the Discount % per administration.
- Choose the Ledger account the discount is booked on.
- Choose the VAT calculation: Excluding VAT, without discount or Including VAT, without discount.
- Click save.
For a global relation, add an administration with the plus button; the discount then applies to that administration only. To stop the discount, clear the percentage and save.
VAT calculation
- Excluding VAT, without discount: the percentage is taken over the amount excluding VAT.
- Including VAT, without discount: the percentage is taken over the amount including VAT.
In both cases the VAT of the invoice stays the same: the discount line has no VAT of its own.
On the invoice
Invoyz adds a Betalingskorting line with a negative amount per VAT rate, on the chosen ledger account. Other categories, such as a cost centre, are copied from the largest line with the same rate. You cannot edit the discount line yourself; when an invoice is processed again, Invoyz rebuilds it from the relation settings.
