I'm looking into starting an Amazon FBA together with a friend. He will sort out the actual products, i.e. sourcing, shipping etc. I will be doing the technical side of things, running the Amazon account, PPC, banks etc.
Here's a question for those running such a business: What percentage of the time and effort does each part take? We want to make this fair, that each side will own a percentage of the business according to the amount of work he will put in. What would you say is a fair split?
