Plan identifiers, stock levels and image matching for products with different colours, sizes or dimensions.
Colour and size options are more than visual choices. Each selected combination needs a valid price, stock state and delivery expectation. Variant planning connects the storefront with warehouse operations.
Define each sellable combination
A blue medium item may have different stock from a red large one. Use consistent identifiers for sellable combinations. Displaying combinations you never produce creates avoidable customer corrections.
Specify image and pricing behaviour
Should selecting a colour change the main image? Does a larger size cost more? Document these rules before editing products. Decide what happens to combinations with missing prices or images.
Choose the stock source
A store-only inventory is relatively simple. With physical retail or other channels, identify the authoritative system. Consider what happens when updates are delayed and an item sells in two places.
Test exceptions
Try ordering the final unit, cancelling it and checking availability again. Consider simultaneous requests too. Testing only products with abundant stock misses the cases most likely to cause operational trouble.
