I've got a site on Squarespace and I'm looking into starting an ecommerce shop on it, reselling items I've purchased from companies. Does anyone have an opinion on using Squarespace for ecommerce? I've read that collecting taxes in the US is an issue, which would likely be a problem for me since I'm in the states. I'm also looking into using Shopify, but then I'd totally have to revamp my site. Anyone have any advice?
