Accessory Guard

Block checkout when accessories, parts, or add-ons are bought without the required base product.

Accessory Guard helps Shopify merchants prevent invalid standalone purchases with simple product-level dependency rules. If a customer adds an accessory, spare part, refill item, or add-on without the required base product, the app blocks checkout and shows a clear message. Optional theme app embeds warn shoppers on product and cart pages. Create rules in minutes, customize messages, and reduce refunds, cancellations, and support tickets.
