Here you can enter the percentage of the invoice amount (amount including VAT is the default setting) that will constitute a possible payment discount.
If you enter something in this field, the program will automatically calculate a possible payment discount when you post an invoice. If payment occurs on or before the payment discount date, the program will apply the payment discount when you post the payment of the invoice.
Do not enter the percent sign. For example, if the discount % is 5.5%, enter 5.5.
You can define that payment discounts be calculated on invoice amounts without VAT by activating the Pmt. Disc. Excl. VAT field under General Ledger Setup.
