Stock & availability

OPTIS reflects stock on the storefront so shoppers aren't pointed at something they can't buy.

Sold-out products

The storefront knows whether each product in a group is available, based on its inventory. A product that is sold out is detected automatically - you don't configure anything in the app for this.

Multi-option availability

For multi-option groups (e.g. Color + Size), OPTIS recomputes which combinations are possible as the shopper chooses - impossible combinations are greyed out, and sold-out ones are marked, just like native Shopify variants.

The group's swatches on the live product page

Availability is read from each product/variant's inventory, so it stays accurate as your stock changes - no manual updates needed.
