We are using your free inventory management solution and we are curious if your multi-inventory would allow us to setup FIFO as well with maybe some inventories that aren't going to be sold (used for promotional stuff).
Sure. You can do both things with Multi-Inventory 😉
Also we would like to know if you Mobile App in beta stage would allow us to use QR codes for scanning the products and take them off the inventory?
And yes, you can scan barcodes and QR codes with the App and it's also 100% compatible with Multi-Inventory.
