Products with variants and stock
Colour, size or bundle — each variant has its own SKU, price, photos and stock. Shoppers see availability at once.
One product, many variants
A T-shirt in three colours and five sizes is one product with variants, not fifteen listings. Every variant has its own SKU, price, stock and photos, so shoppers pick colour and size on the product page and see straight away whether it is in stock.
Model sets and colours group related products: from one model a shopper switches to another colour, without duplicates in the catalog.
What you can set
Per variant, with a compare-at price for discounts.
Quantity on hand; when it runs out, the storefront tells the shopper.
Separate images for each colour or bundle.
Material, season, brand — for filters and comparison.
Stock from your back office
If inventory lives in an ERP or accounting system, stock and prices update through the Integration API or an import. The store sends a webhook whenever a variant’s stock changes.
