My company resells goods that have a certain customization... 

1. Quote customized products to my costumer: I think, having an attribute text field with features descriptions and custom price.
2. Customer accept my quotation. (I think) MTO process must to start
3. The products is received and id ready to send to our costumer (no changes is needed... we are only trader)

So, every custom product is different from another. Every product is dedicated to precise customer.  My question is: how can I delivery the exactly product chosen by in sale order?

thanks in advance

Giordo.
