The "Product combinations" feature allows to set a separate image/price/SKU/quantity/low stock notification for each set of product options. When this set of options is selected, Ecwid will always use the values(e.g. image) assigned to the combination instead of the base/default ones. Check how it works in our demo store.


Product combinations can be used in a ton of different ways. Just to list a few: 

  • Track inventory per option (stock based on options). For example, you can have one t-shirt available in “S” and “L” sizes, and then you can have a separate stock for each size. So for example, if “S” size is sold out, your customers will still be able to purchase the “L” one. This feature will be especially useful for merchants who sell apparel.
  • Assign different images to your options. When a customer selects an option, Ecwid will update the products main image. This will allow your customers to instantly see what they are going to buy and what the option looks like.
  • If your options affect (raise/lower) your product price, the product combinations feature will allow you to update your product price on the fly. Your customer will be able to see the new price immediately right on the product details page.
  • Assign different weight to your options. If you use options to sell products in different packs or bundles, then your shipping methods will return more accurate rates.


This feature is only available with the Silver (available for users registered before 10/30/2012), Business and Unlimited plans, so it’s an awesome reason to upgrade your account and support our team!





Can I set same SKUs for a product and its combinations?

Ecwid allows to set same SKUs for a product and its combination unless the combination's stock differs from the base product's one. In other words, if you set a different in-stock quantity for a combination, you'll have to set a different SKU for it. We are basing such a logic on a reasonable presumption that if a combination has its own inventory, it is treated like a separate unique item, so it apparently should have a unique SKU. 



If I use product combinations to assign separate SKUs to different options, will that additional SKUs be included into the product number limit for my account?

Ecwid limits the maximal number of the products you can totally have in your store. The plan-specific limits of the current Ecwid plans are shown here:


However, those numbers do not include SKUs from product combinations: you can have more SKUs than your plan limit totally when using combinations, only the number of base products is limited. Combination with a separate SKU does not count as a separate product, only the base product itself does.
