The number of barcodes you need depends on the number of unique products you have, including variations in size, colour, or other factors.

Each unique product variation requires its own barcode. For instance, let's take an example of three t-shirts in red, blue, and white colours, and in small and large sizes.

Here's how you break it down:
Red T-shirt, Small Size
Red T-shirt, Large Size
Blue T-shirt, Small Size
Blue T-shirt, Large Size
White T-shirt, Small Size
White T-shirt, Large Size

Each variation is considered a unique product. So in this case, you have six unique products and therefore you would need to buy six barcodes.
