Wooecommerce- Logged in member product order question.

Before I hire devloper…question: do any of the ecommerce solutions (particularly wooecommerce which seems to have best reputation) send back member info (esp. username) to us with order info and can it prepopulate the store with info we already have from logged in users due to their site membership…email, name, etc? Or does this require addl. coding or custom fields in store perhaps?

Or any chance we could combine purchase of product with registration for website, since gathering most of the same info when ordering.
Thanks.
