The Overprice commission model is used for businesses that make rate agreements with owners and pay them only when there are reservations in the periods.
To sum up, you set, with the owner, a table of prices throughout the year (net prices) and another table of prices for the guest. And your business commission is the difference of amount between the two of them (your revenue and the amount to be paid to the owners).
How to see the amounts on the listing page
After setting up the Purchase Prices (Net) on your listing, you can see it or change it by accessing the [Finance > Registration of Purchase Prices (Net)] menu.
How to see the amounts on the forwarding routine
On the reservation's forwarding, the total amount to be paid to the owner will arrive on the Buy Price field, based on the calculation made on your table of Net Prices.
