Tried a few linux POS lately: lemon, bravo and now floreant.
None of them has all the futures needed in a restaurant.
Floreant misses the most important future: recipe. When i sell a hamburger it is made of bread, meat (that is also prepared from more ingredients), salad.. etc. A restaurant POS needs to substract all this ingredients from stock.
Same goes for the bar where u can also have cocktails made from 2 to 10 ingredients.
There is no restaurant that only sales rady-made products.
Otherwise, great work and for free = respect.
Hope i was brief and descriptive enough.
PS lemonPOS can work with grouped products but lacks restaurant futures (table, reservation, etc)
