looking for a mobile app that can be used to take orders and create invoices from a sales rep or customer directly by logging in. When logged in want to be able to have a item name picture description and price. Want to be able to create and print barcode skus for products. Want a backend that gives us inventory counts and sales data. Also need an order picking page so when we pick an order we can use a mobile device android or ios to scan barcode so that it comes out of inventory and on to a re order sheet weekly.
