A customer could have ordered extra products during their stay. This could be an extra cup of coffee or a lunch for an unexpected guest. You can either change this directly in their booking or book the product separately.
To book a product separately, select your venue in the top left dropdown, and click on create new+, and product booking. Fill in the fields that are marked with a red asterisk, and the product you would like to book. Confirm the booking by clicking on “continue” in the bottom right corner.
