See every featureCassian connects to your store and watches it continuously, so you hear about problems before your customers do. It monitors your order flow and tells you when orders slow, which is often the first sign that a shipping rules has broken. It tracks every product price and flags zero-dollar, inverted and bulk changes.
Some store failures announce themselves. The expensive ones don't. Discounts stop applying. Free shipping starts charging. Products get disapproved in Google overnight. Nothing errors, and orders keep going out until someone complains. ShopCanary checks every order against rules you declare and watches your Google Merchant Center feed.
