If you're going to allow your customers to choose from different services you offer when creating their bookings, you'll need to configure the service items first. 

When adding services, they must already be added in KC desktop as this is where it will pull the item from. If you have not already setup your services in desktop, you should go do that now. Once added, return to the OLR setup. 

To add these services in KC desktop go to File, Lists, Other Services tab. 

• On the services page, click "Add New" to create a new row.
  
  
• If this will be "active" meaning available for your customers to choose during an OLR, place a check mark in the active box.
  
  
• Click in the "linked item" field and your services from KC desktop will populate. Choose the proper one.  This is a requirement or it won't invoice properly.  Your client will not see this name.
  
  
• Set your title which your clients will see.  You can put any title that you want.  
  
  
• Set your description which your clients will see.  You can put any description you'd like.  This gives you a great opportunity to describe services in such a way that clients are excited and want to choose it for their pet.
  
  
• Set your "Pet Type" If will be available for all pet types, leave blank.  If this is to be a dog or cat only service, choose that option.  If a client is booking their dog then only dog services will show for them.
  
  
• Set your rate
  
  
• Choose to show price to customers or not.
  

• You can use the Up/Down arrows to sort the list in the order you want your clients to view them.
  

• Make sure to hit Save Settings when done.
