Daily Maximum Rate: What to Charge When Someone Parks All Day
The way to charge someone who leaves their car for 9 hours — or three days — without the bill turning into something nobody wants to pay is to set a daily maximum: the customer pays by the hour as usual, but once the total hits a certain amount, it stops there until 24 hours are up. It's the answer to the customer who asks "and if I leave it all day, what does that run me?"
Here's how it works, with numbers, and when it's worth setting up.
The problem: the bill nobody wants to pay
Every hourly lot runs into the same scene. A customer drops the car off at 7 a.m. and picks it up at 6 p.m. That's 11 hours. If you charge $4 for the first hour and $3 for each one after, the bill comes to $34.
One of two things happens next, and both are bad:
- The customer argues. "Thirty-four dollars for a car that just sat there?" And that argument, at the booth with a line behind them, is one the customer usually wins: the attendant discounts it on the spot, and there goes your control over pricing.
- The customer doesn't come back. They go to the lot down the street advertising "all day $20" and you never see them again.
The extreme case is the one who left on a trip and parked for three days. With no cap, that bill turns into a problem, not a payment.
What a daily maximum is
It's a ceiling. You tell the system: "charge by the hour as always, but never go past $20 in a single day."
The customer who stays two hours pays for two hours. The one who stays twelve pays the maximum. Nobody overpays, and you don't lose the long-stay customer.
One thing matters here: the day is counted from the moment the car came in, not from midnight. If it came in at 10 p.m. and left at 1 a.m., that's 3 hours, not two days. That's the difference between a fair charge and an angry customer.
How it's calculated, with numbers
Take a common rate: $4 for the first hour, $3 for each additional hour, $20 daily maximum.
| Customer stays | Would pay without a cap | Pays with the cap | What happened |
|---|---|---|---|
| 3 hours | $10 | $10 | Never hit the cap, pays normally |
| 8 hours | $25 | $20 | Passed the cap, stops there |
| 12 hours | $37 | $20 | Same: the cap is the cap |
| 30 hours | $91 | $38 | One full day at the cap + 6 loose hours |
| 48 hours | $145 | $40 | Two days at the cap |
Look at the 30-hour case: the first day charges the cap ($20) and the remaining 6 hours are charged normally ($18). You don't charge a second full day for 6 hours.
And one detail that matters: the first hour is charged only once, at the start of the stay. The customer who stays three days doesn't get billed for a "first hour" every 24 hours. Same with grace minutes, if you have them set up.
When it's worth setting up
1. If there are offices or shops nearby. The person working next door needs to know what the day will cost. With a cap, you have a price you can quote on the spot: "all day is twenty." Without one, you have to do the math every time, and it always sounds expensive.
2. If you're near a station, an airport, or a hospital. Multi-day stays aren't rare there — they're the bread and butter. The cap is what makes that customer possible in the first place.
3. If the lot next door already advertises "all day." A cap lets you compete without giving anything away to the customer who only stays two hours. You charge hourly to the short stay and a day rate to the long one, with the same setup.
How to set it up in Parqueadero.app
It's one field on the rate for each vehicle type. You enter the daily maximum and that's it: the system applies the ceiling on its own, on every charge, without the attendant having to remember anything or do math.
The system also won't let you set something that makes no sense: you can't set a maximum lower than the price of the first hour, because then nobody would ever pay a full first hour.
It works with hourly and per-minute pricing. If you charge in fractions of an hour or by time bands, the cap doesn't apply in those modes yet.
And it works offline: if the connection drops, the system still calculates the charge with the cap, right on the device. Here's how.
Frequently asked questions
Does the maximum reset at midnight? No. It's counted in 24-hour blocks from the moment the car came in. If it arrived at 8 p.m. Monday, its first day runs until 8 p.m. Tuesday.
What if the customer stays under the maximum? They pay the normal hourly amount. The maximum only acts as a ceiling; it never charges more or less than it should.
Can I set a different maximum for cars and motorcycles? Yes. The maximum is part of each vehicle type's rate, so each one can have its own.
Is this the same as a flat rate? No. With a flat rate everyone pays the same, even for 20 minutes. With a daily maximum, the short stay pays little and only the long stay reaches the ceiling. It's the best of both models.
Does the customer see the maximum on their ticket? They see the amount they owe, with the cap already applied. They don't need to understand the mechanics — they just see that the bill didn't blow up.
In short
A daily maximum solves the worst argument at the booth: the customer who parked for many hours and sees a bill they weren't expecting. You charge hourly to the short stay, put a ceiling on the long one, and the system applies it on its own — offline too — without anyone doing math by hand.
