Shopify add to cart not working? Find out before your customers do.

AskQA monitors your Shopify store around the clock. It opens a real browser, clicks Add to Cart, and checks the item actually lands in the cart. If anything breaks — a theme update, an app conflict, a Shopify rollout — you get an alert with a screenshot in minutes.

Your add-to-cart button can break without warning

Theme updates, app conflicts, and Shopify platform changes can silently disable your buy button. In April 2025, Shopify rolled out an "Add-to-Cart Limit" feature that made products unpurchasable overnight — store owners only found out from angry customers. A broken cart button means lost sales every minute it stays undetected.

Know in minutes, not hours

AskQA tests your Shopify store the same way a real customer shops it. It visits your store, finds a product, clicks the Add to Cart button, and checks the cart page — all in a real browser. If any step fails, you get one alert with a screenshot showing exactly what broke. Set it up in 2 minutes, runs on autopilot.
