Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureFor stores that make products from a customer's own file: prints, photo gifts, signs, engraving. The upload box shows the file types and size limit we really enforce, so no shopper is told one limit and refused at another. The file name goes on the order line; the file stays in private storage until the day you choose.
Dropslot adds an upload field to your product pages so customers can attach photos, artwork and files to what they buy. Each file is saved to your store's own Shopify Files and its link appears under the item on the cart, checkout and order. Make the upload required, limit file types and size, and show the field only on tagged products.
