Why Clothing Shops Need Size and Colour Modelled as Separate Variants

A shop may have one kurti design but sell it in multiple sizes and colours, each of which needs its own stock count and tag. The article describes VyaparNext, a point-of-sale system for Indian clothing shops built by Smart Byte Labs in Surat. It separates the design, the options that vary, and the individual variants that carry stock and barcodes. Storing size and colour as free text on bills leads to inaccurate stock counts and inconsistent spelling, while creating a separate product for every combination loses the grouping of the design. Keeping stock at the variant level and linking variants to a shared design avoids both problems.
