Install Patch It Up Pro from Shopify
Open the Patch It Up Pro listing in the Shopify App Store and click Install. Review the requested permissions and approve any Shopify billing confirmation shown. Shopify signs you in automatically and returns you to the app; you do not need a separate Patch It Up Pro login or need to type your store URL.
Open the guided Setup page
In Shopify Admin, choose Apps, open Patch It Up Pro, and select Setup. Keep this checklist open as you work. Its buttons take you directly to the correct Shopify theme and product screens.
Configure materials, sizes, and pricing
Use the Patch It Up Pro settings to choose the materials and sizes you sell, set your customer prices, and match the builder colors to your store. Save each section before leaving it.
Choose the Shopify product that will use the builder
Create a product such as Custom Patch, or open an existing product. Add the exact product tag custom-patch, using lowercase letters and the hyphen, then save the product. This tag tells Patch It Up Pro where the builder should appear.
Enable the Patch It Up Pro app embed
Go to Online Store > Themes and click Customize on your active theme. Open App embeds from the theme-editor sidebar, turn on Patch It Up Pro Global, and click Save. The Setup page also includes an Open Theme Editor shortcut.
Add the Custom Patch Builder block
In the theme editor, open Products > Default product, or the product template used by your patch product. In Product information, click Add block, select Custom Patch Builder under Apps, place it near the product price, and click Save.
Preview the product page
Open the tagged product on your storefront and choose Create Custom Patch. Upload or generate artwork, choose a size and material, and confirm the preview and price update correctly.
Test the Shopify cart
Set the quantity to two or more and click Add to Cart. Confirm Shopify's native cart opens with the selected quantity, design name, size, and customization details. Change the quantity, continue shopping, and add another product before testing Checkout.
Publish and monitor your first orders
When the test is correct, keep the theme changes published. Customer orders use Shopify checkout and appear in Shopify Admin, while Patch It Up Pro keeps the associated design information and production-ready artwork available in the app dashboard.
