Fractional Quantities For POS

At this time this is the only app that works for fractional inventory. I run a fabric store and we need to sell in different increments. The app is a bit cumbersome and sometimes takes to long to load to make it worth the price however with shopify's lack of support for fractional quantities this is the only solution available. It's adequate. The font and line size is rather small when in the app at the POS and there are days the app doesn't work at all but has been averaging about one day a month of downtime. Its better than not having a solution at all.
