28.1 Introduction

In the application there are four reasons for an invoice to include a discount:

1. 1.

   Because a discount is entered by the sales person creating the quotation, sales order or sales invoice

2. 2.

   Because the customer’s payment terms include a discount for paying early

3. 3.

   Because the customer belongs to a type of business which is entitled to discounts

4. 4.

   Because the customer has been assigned a price matrix leading to discounts

This section deals with items 3 and 4 only.

@@@ types of business are ’old school’; price groups have been introduced to replace types of business with a more fine-grained structure.
