As you add more services to your Setmore account, they'll stack in place according to the order in which you add them. However, you can easily drag-and-drop services to change their order.
This order will reflect how services are displayed on your Booking Page.
Move services up or down
Start by going to Settings > Services. Here, you will find your services in their categories.
Click and hold down on the service you would like to move. Drag and drop the service into a new position. Changes will take effect immediately.
