Accounting by Guesty is a premium feature. Please contact us to discuss activating it.
As explained here, Guesty offers two owner statement templates for you to choose from: The default template and the debit/credit template. The template you choose will be applied to all of your listings, and cannot be used for only some listings.
Contact us if you want to switch from the default template to the debit/credit template or vice versa. Once completed, you can regenerate existing owner statements to fit your new template.
