I've been evaluating several PIM products and I have a few questions.

1. Is it possible to have a PIM without the stock management?

2. I work in the cosmetics industry and cosmetics manufacturers only recently started to implement things like EAN and barcodes before that it was a huge mess and actually stil is.

I have product variants with the same EAN code.
I have products which are the same but have different EAN codes.

Is it possible to assign multiple EAN codes to one product?

3. Is there a Hello World type guide for implementing your own apps?

4. How can I assign different prices to product variants?

5. How can I assign multiple prices to a product, rightnow I can only see the cost and sales prices but we work with bulk and consumer prices.
