The right move would be to spare no expense and hire a professional firm to build and re-platform a new site. Unfortunately they chose to rebuild in-house and trust the job to a programmer who's never built an ecom site
He wants to use Prestashop and Stripe for starters... He couldnt tell me much beyond that. My knowledge in this is VERY limited but I know just enough to know I should be concerned. Problem is I dont know the right questions ask to make sure we arent making huge mistakes that will makes us have to start from square one after he drops the ball.
I know this post lacks a specific question besides platform advice but ANY general input would be much appreciated.
