Variants & merging
When one product should hold several sizes or colours, how to set variants up, and how to merge products you already added separately.
A variant is a version of the same product — a size, a colour, a pack size. One listing holds them all instead of you creating a separate listing for each.
When to use variants
It is genuinely the same product: the same kadai in 20cm, 24cm and 28cm. The same kurta in S, M, L, XL. The same container in a pack of 3 and a pack of 6. A buyer would expect to choose between them on one page.
They are different products that happen to be related — a kadai and a matching lid are two products, not two variants. If a buyer might want both at once, they need to be separate.
Setting up variants on a new product
Reach step 2 of the product form
Pricing, SKU & Inventory.
Turn on 'Has Variants?'
The pricing panel changes from one set of fields to a per-variant table.
Define your options
Size, colour, pack size — whatever separates them. The generator builds every combination for you rather than you typing each one.
Give each variant its own SKU, price and stock
They can differ. A 28cm kadai can cost more than a 20cm, and each holds its own stock count.
Finish the remaining steps and publish
Shipping and visibility work exactly as they do for a single product.
Merging products you already added separately
If you have already created the same shirt three times for three sizes, you do not have to delete and start again.
Where to find it: menu → Products → Products tab → Merge products into variants.
Open Merge products into variants
The button sits next to Import catalog above the product list.
Pick the products that are really one product
Select the separate listings you want joined.
Choose what separates them
Size, colour, or whatever the differing option is.
Confirm
They become one listing with the options underneath, each keeping its own SKU, price and stock.
Stock with variants
Stock is held per variant, not per product. If the medium sells out, the medium shows as unavailable while small and large stay buyable. That is the behaviour you want — and another reason not to split sizes into separate listings, where an out-of-stock listing does nothing useful.
The Inventory screen lists each variant as its own row with its own SKU, so you can update one size without touching the others.
