Booking Manager allows you to make custom reservations that are not related to any actual boats and/or periods.To create a custom reservation you start like you would any new reservation. Click New (1.), Select a yacht (2.) and press Choose (3.) then Select a date (4.) and press Ok (5.).
Next, find the option (1.), switch the Status to Custom (2.) and press Apply (3.).
This will switch the view to Custom (1.). Now you can add Agent/Client (2.), and you can mark the reservation as a Free entry reservation (3.).
Marking the reservation as a free entry removes the Boat and Period from the documents.
Now in Calculation, if you want, for example, to issue an invoice for something non standard, remove the Base price (1.), then uncheck Options not invoced (2.), add some extra to the calculation (any) (3)., then rename it (4), enter the price (5.) and the tax rate (6.). Finally press Apply (7.)
With all this setup you can issue the invoice to the correct client (1.) for the specified item with the set price (2.) and set tax rate (3.). The first tax rate that is 0 is set like that since the Base price is 0.
