How are room prices calculated?
From Jomres v4 manual
Room pricing in Jomres is a complex issue. The end price of a booking can vary wildly from what was entered as a room price so it will help you to have a basic understanding of how the pricing is arrived at.
In short first the base value of the selected room(s) is calculated over the number of days of the booking. If you're charging per person per room AND you have created some guest types then the value for each guest is calculated OFF the base value of the rooms.
I'll give you an example:
Room cost 50, Guest types: Adults no variance, Children -50% In the booking form selected 1xadult & 1xchild
Charging per night: 50
Total cost 1 night 50
Charging per person per night 50 x 1 for the adult (50 X 1) / 2 for the child.
Total cost 75.
