I think you are right with just collecting minimal information. Systems we have built in the past where people want to collect all the billing information tend to cause more issues with transactions being declined because someone adds apt 7 or some thing else into the address field that doesn't match up. Unless you are selling a product where fraud would be a concern I could see collecting more information. I would think that fraud using SasS is pretty low compared to buying consumer electronics and such.
