Bundle Quantity?

Our products are very large and some have several boxes per product. These boxes are not sold individually. Each box has it’s own barcode and need to keep stock.

Currently I am setting up each box as it’s own item and using Item Bundle to ‘Sell’. Is there a better way of doing this?

Problem is that I cannot see ‘available quantity’ for the Bundles. Eg:

  • Bundle1 = 2x Box1 + 1xBox2
    (Currently we have 4xBox1 and 4xBox2)
    I want to know the quantity which should be 2 for Bundle1

Edit: Just noticed that product bundle is not compatible with POS. This would also be inconvenient as we want to sell these ‘products/items’ using the POS.
