How to pause or stop orders on website

Hi:
I'm going to be away for a few weeks. I'd like to keep my website "live", but I need to stop people from ordering during that time. Is there any easy way to do that other than changing code? Thanks! V 3.0.3.8

You could try disabling all your payment or shipping extensions. That may be a bit annoying for potential customers if they have entered all their details and only find out at the last stage of checkout.

You could also set the stock of all your products to 0 and not allow checkout of out of stock items in the settings.

Thanks ADD! Will give it a try

Set the product stocks to zero, and also put an HTML module on the homepage via the design layouts informing the users when the products will become available again.
