KC RIVER MARKET HYDRO review for Stocky

Been trying to use this app for about a year to manage my inventory for two physical stores and my online store. Very difficult to use the Purchase Order feature for my entire business. The app only allows POs for each store independently of each other. I have tried calling for help through Shopify, but hard to find anyone with expertise. I can view all my inventory on one screen, so why can’t the app be able to do a PO for all of the inventory? Doesn’t make sense.
