I am working on developing a replacement for an existing application which requires many detailed entries for the selection of a product. For example, the customer selects product A. This product will have multiple options, like number of "A" parts, "B" parts, etc. Then each "A" part can have "1", "2", etc. styles. There will also be additional customizations with price variations.

My objective is to use as few forms for data entry for each product as possible. I thought about using a MDI parent form with multiple children forms.

Is this possible? Are there any other ways to design the interface to make it as user friendly and simple to use as possible?

I would appreciate any suggestions or recommendations.
