Hi,

To implement seasonal pricing for your holiday apartment in Odoo's Rental App without custom programming, you should leverage Odoo's Price List system. First, enable "Multiple Sales Prices per Product (Price Lists)" in Sales > Configuration > Settings. Then, create a separate Price List for each season (e.g., "Rental - Low Season," "Rental - Mid Season," "Rental - High Season") under Sales > Configuration > Price Lists. For each seasonal Price List, define the specific product, its daily price, and the start and end dates for when that season's pricing applies. When creating a new Rental Order, you will then need to manually select the appropriate seasonal Price List from the "Price List" field on the order form, which will automatically apply the correct daily rate for your apartment based on the selected season. Be aware that for rental periods spanning multiple seasons, this method requires manual selection for the entire period, and fully automated, date-driven price splitting for mixed-season rentals would require custom development.
