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

When adding products, 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 inventory in desktop, you should go do that now. Once added, return to the OLR setup. 

• On the products 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 inventory 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 use any title you want.
  
  
• Set your description which your clients will see.  You can use any description that you want.  This is a great opportunity to have a description that makes clients excited and they'll want to choose this product for this pet.
  
  
• Set your rate
  
  
• Choose to show price to customers or not.
  

• You can use the Up/Down arrows to set the order these will show on the OLR appointment screen.
  

• Be sure to hit Save Settings at the top of the screen when done.
