STOQ Help Center
Everything you need to set up and run Preorders and Back in Stock alerts with STOQ. Pick a product to dive in, or jump to a popular guide below.
STOQ is a Shopify app. Preorders adds a Preorder button so you can sell a product before it is in stock, and take full payment or a deposit. Back in Stock adds a Notify me button to sold-out products, so shoppers can sign up and get an email or SMS when you restock. These guides show the exact steps in the STOQ app to install it, set up each feature, connect tools like Klaviyo and Shopify Flow, and fix common problems.
Preorders
Sell products before they're in stock. Take full payment or a deposit, and fulfill on your own schedule.
