An invoice program. The program should also contain a small module for customer treatment.
How to determine the price:
* Each article has a default retail price
* All customers belong to a category with corresponding reduction for all purchases, this reduction can not be cumulated with other reductions
* When large amounts of a certain article are bought an reduction can be attributed, this reduction can not be cumulated with other reductions
The price of the article is the lowest price possible.
What schould be available on the invoice:
* Customer Data
* Date Invoice
* Number Invoice(auto numbering)
* due date (different possibilities: 30 days; cash; 60 days,...)
* Article (quantity, description, default retail price, charged retail price, total for article)
* Total amount to pay
All functionality should be in the objects not in the user interface
