Dynamic pricing
The Dynamic pricing tab on a category holds two instruments: surcharges, which put the price up, and length-of-rental discounts, which bring it down.
Surcharges
A surcharge is a percentage or a fixed amount per day, and you can scope it by date range, by weekday, or by both.
Typical uses:
- High season, +25%, from 1 July to 31 August, every day.
- Weekend, +€ 5 per day, all year, on Saturdays and Sundays.
- Peak weekend, +30%, in July and August, on Saturdays and Sundays only.
Both sides of the date range are optional. Leaving both empty gives you a weekday-only rule ("every Saturday and Sunday, all year"), which is what most weekend pricing actually is. Ticking no weekdays means every day.
Each surcharge has a name (the screen suggests "for example: high season or weekend"), a type, an amount, its dates and its weekdays, and an on/off switch so you can prepare next summer's rule now and switch it on in June.
A week that only touches two high-season days is charged 2/7 of the high-season surcharge, not a full high-season week. A fixed surcharge is charged once for each matching day. This is what stops a rental that starts on 30 June from being billed as if the whole week were July.
Length-of-rental discounts
A discount tier says "from N days, take X% off". Add as many as you like (from 7 days 10%, from 30 days 20%), and the most generous qualifying tier is used.
The screen puts the reasoning plainly: a week should not be seven day-rates.
The discount is applied after the surcharges, to what the rental actually costs. So a high-season fortnight gets its high-season surcharge and then its fortnight discount, in that order.
What happens to existing bookings
The rules are frozen onto a booking when it is made, exactly as prices are.
That matters most when you move a booking. If a customer shifts their rental from May into the high season, it is re-priced as high season, using the rules that were agreed with them, at the rates that were agreed with them. You are not silently giving away a summer rental at spring prices, and you are not silently re-pricing an old booking at rules you invented afterwards.
Bookings made before you set any rules up price exactly as they always did.
Bundles
Bundles carry surcharges too.
- A period-scaled bundle prices each component with that component's own rules, exactly as each would be priced outside the bundle.
- A fixed-price bundle spans several categories, so no single component's season applies. It takes the combined rules of everything in it, and an identical rule shared by all its components is applied once, not once per component. A bar package whose five categories all carry "peak weekend +25%" gets +25%, not +125%. Genuinely different rules do stack.
