description: "Some orders need more information than Shopify captures by default. This app lets you add custom fields to line items using rules you define. A rule can set a fixed value, build a value from product, variant, & customer variables, or let the customer type their own answer on the product page. You choose which products a rule applies to using product & customer conditions. Fields appear on the order in Shopify admin & through the API, so the data reaches your ERP, fulfillment, and other systems."
