If you need to pause order processing without taking your entire store offline, WSM provides a simple option to disable the checkout functionality.
By enabling the Disable WebStore Checkout setting in WSM, customers will be prevented from placing any orders on your site. This can be especially helpful in situations such as:
Performing system maintenance or updates
Preparing for a new product launch
Resolving inventory or fulfillment issues
Managing unexpected downtime or troubleshooting
When this option is enabled, all other aspects of your WebStore remain visible—products, pages, and content can still be browsed—but customers won’t be able to complete purchases until you re-enable the checkout.
How to Disable WebStore Checkout
Steps:
Log in to WSM.
Go to Settings > All Config Options.
Locate and enable Disable WebStore Checkout.
Save your changes at the bottom of the page.
