Removing Quantity Selection on Squarespace Website Shop
When selling something like a service online it may not make sense to have a quantity selection field in your checkout experience. If you are using Squarespace, there’s a way to disable that field.
Note this method only works for services sold on your Squarespace shop. This process takes a minute to complete.
Log into your Squarespace website and click on Commerce on the left side menu bar.
Click on Checkout.
Scroll down to a checkbox “Let Customers Buy Multiple Service Products” and uncheck it.
Save your changes and check your shop. Any service you offer for sale should no longer show a quantity selection field.
