Sizes, colours and options.
WHAT A VARIATION IS
One product with options: sizes, colours, capacities.
Each variation can have its own price, stock, SKU and image.
HOW TO SET IT UP
Create the attributes first: size, colour.
Create the product as variable, assign the attributes, generate variations.
WHAT TO SET PER VARIATION
Price, if it differs Stock, if tracked separately Image, if it looks different
SKU
THE IMAGE POINT
A colour variation should show that colour.
Customers selecting red and seeing a blue photograph do not buy.
COMMON MISTAKES
Creating separate products for each size, which fragments the catalogue Not setting stock per variation, so out-of-stock sizes can be ordered Generating every combination when some do not exist
THAT LAST ONE
Remove combinations you do not stock.
WHAT TO TEST
Order each variation type and confirm the correct one appears in the order.
