Cutly adds a custom size calculator to your product page. Customers pick a roll width, enter the length they need and see the exact price before adding to cart. The price is calculated on the server and checked again at checkout, so a cart can't be edited into the wrong total. For goods cut from a roll, Cutly tracks the remaining length to the centimetre and keeps your Shopify stock in step after every order, cancellation and refund.

• Live price by width and length, shown on the product page
• Roll stock tracked by length and updated after orders and refunds
• Server-verified prices that can't be changed in the cart or at checkout
• Price rules by collection, tag, product type or vendor
• Works with your theme's own price and Add to cart button
