Prompt payment discount calculation

On the prompt payment discount calculation page, it provides an overview of invoices that have been paid on time for customers have a prompt payment discount amount (set on their card file). 

A prompt payment discount is calculated by multiplying the total invoice amount (excluding tax) by the discount percentage to encourage early payment.

Here is how it works:

• Enter a prompt payment discount % against a customer's card file. To do that:
  • Edit a customer card file
  • Click "Options" from the left
• Run the prompt payment discount calculation
  • Go to Sales menu > Invoices & credits
    • Click on the blue link "Prompt payment discount calculation" (top right-hand side of the page)
  • By default, this program shows
    • Invoices have been fully paid on time
    • Customers have a "prompt payment discount %" value
    • Provides a quick way to create a credit note for the qualify discount amount
    • Once the credit note has been committed, the respective credited invoices will be marked as discount credited; in turn, the new credit note will be sent to Xero so it can be used to offset the customer's invoices/lump sum payment
