Would like to have a custom build product feature for oscommerce similiar to this site [url removed, login to view] for the front end. This will allow customer to customize their system as they wish.
For the back end. we require the following:
1. Have the discount field in fix $ amount for the whole system
2. Make sure each item in the customs build has to deduct from inventory correctly just as when customer order each individual part.
3. The invoice must show clearly product name, and model for each item in the customs system
4. Item out of stock must not shown in the options for the component
5. If the default item of a component is out of stock, set the next available item to be default.
