A product will either be single product with a single SKU, price etc. Or it will have several variants like size, color, material, logo, or any other kind of variation. Products with variations may have different SKUs, prices, images etc. so the forms will be different.
After adding the basic details to the product you’ll can choose whether the product uses variants. The screenshot below shows the form when the product is just a single product. For example, if you’re adding a mug, mouse mat, USB stick etc.
If you’re adding a product with variants then skip to the next section.
