The short answer
Separate pages, with their own prices and their own list of what is included. The arrangement is different, the price is different, and the level of trust the owner has to extend is far higher, so it does not belong as a row at the bottom of the drop-in visit table.
Why they need splitting from visits
A thirty minute visit is a service. Somebody sleeping in the owner's house for nine nights is closer to a tenancy in how it feels to the person agreeing to it.
The owner's questions change completely. Not "will the cat be fed" but "who is in my house, which bed are they using, are they there all day, can they bring their partner, what about my post and my heating, and what happens if the boiler fails."
A page that answers those is a different page. Trying to answer them in a footnote under a price grid is why so many sitting sites get long messages instead of bookings.
What the overnight page has to say
Define the night. This is the single biggest source of misunderstanding in sitting. Say the hours: arrive by a stated time in the evening, stay overnight, leave by a stated time in the morning. Say whether daytime hours are included or charged as visits on top, and how long the animal is alone in between.
Then the practicalities. Whether you sleep in the house every night without exception. Whether the dog sleeps in your room or its own. What you do with your own day, since most sitters go to work and return. Whether you have a car and where you park.
Price it per night, and say what a night includes and what it does not.
What the house sitting page has to say
House sitting is the fuller arrangement, and the difference is that you are looking after the property as well as the animal.
Say what that covers: post and deliveries, bins out on the right day, plants watered, lights and curtains varied so the house looks lived in, heating checked, and the owner told promptly if something breaks. Say what it does not cover, which is usually cleaning, decorating, and letting in tradespeople unless agreed in writing.
Say who else may be present. Whether a partner stays, whether you have visitors, whether you would ever have anyone in the house who has not been vetted. The honest answer, stated up front, is what an owner is looking for.
Price it in a unit owners understand
Per night for overnights, per day or per week for house sitting, whichever matches how you sell it. Whatever you choose, write the unit in the heading and repeat it under the table.
State the extras separately: additional pets, the bank holiday and Christmas surcharge, and whether daytime dog walks during a house sit are included or charged. Long bookings are where an unstated surcharge does the most damage to a relationship.
Never publish a single number without a unit next to it.
The proof has to be stronger here
Everything on your trust page matters more for an overnight arrangement. Insurance including care custody and control. The background check, named and dated. Pet first aid. References, ideally from clients whose houses you have actually stayed in, which you should ask for specifically.
Add a short paragraph about how you treat somebody's home. It sounds obvious and it is the thing owners most want to read.
Put it in the agreement, not just on the page
The service agreement your software sends should carry the arrangement in the same words the page uses: the hours, what is included, the surcharge dates, cancellation terms for long bookings, emergency vet authority, and what happens if the owner is delayed coming home.
Delayed returns are worth a clause of their own. Flights get cancelled, and both of you will be glad it was written down.
Booking still starts with a meet-and-greet
For an overnight or a house sit, the meeting is longer and covers the house as well as the animal. Say that on the page, and say that for a first house sit you would rather do a shorter trial booking before somebody's three week holiday.
Sitters who offer that trial get more long bookings, not fewer, because the owner is not risking the whole trip on a stranger.
Where this sits
Overnight and house sitting pages, with their own prices, hours and inclusions, are part of how we build a pet sitting website, and the same page-per-arrangement pattern runs through the other pet business websites we make. Packages are on pricing. Different arrangement, different page.
