An easy way to start would be to move from paper to a cloud based app like Dropbox or google sheets. Create a spreadsheet that replaces what your paper forms/lists are doing and then access those apps on your tablets at the store or phone away from the store. Color the rows to represent different statuses of the orders (in production/packed/picked up or complete) and train employees accordingly. I found a DIY app program called Zoho where I built my own app that we use across our 2 locations and syncs to my phone that we use for juice inventory, produce counts, cleanse orders and other preorders, etc. With it, you essentially have a form you use to input the data and a reports tab to view the data. It works out nicely. I would also love to demo Canteen when it’s ready as it looks like they are working on a fully integrated system for all backend juice bar needs.
Here’s a screenshot of the app I built:
