Hello Sir/Madam

I am new to Zakya. I am planning to subscribe to zakya

But i have just one problem.

How can i sell an item with multiple unit.

Like for example.

I have an item "Pepsi". 1 box contains 24 bottles.

So on the POS i wanted to sell both in bottle and also in BOX.

I don't want to create composite item because it is the same item and also its difficult to maintain the stock

PLEASE HELP
