How We Built a Custom Booking System for a Pet Sitting Business
One of the most rewarding projects I've worked on was building a complete booking and scheduling system for a local pet sitting business. The owner had been running the business for a couple of years, had built a solid client base through word of mouth and social media, and was at the point where the manual approach to booking was actively holding them back.
This is the story of what the problem looked like, what we built, and what changed.
The situation before
The owner was doing everything through a combination of text messages, a personal Google Calendar, and Square invoices. Here's how a typical booking worked:
A client would text asking about availability for a specific date. The owner would check their Google Calendar, reply with open times, and go back and forth until they landed on a slot. Then they'd ask for the pet's details — or, if it was a returning client, try to find the details in old text threads. Once the booking was confirmed, they'd manually add it to Google Calendar and send a Square invoice for a deposit.
Reminders? Manual, if they remembered. Sometimes they'd text the client the day before, sometimes they forgot. No-shows happened a couple of times a month.
For a while, this worked. But the business had grown to 60-80 bookings per month across multiple service types — drop-in visits, daily walks, and multi-day pet sitting stays. The text volume was overwhelming. Double-bookings had happened more than once. The owner estimated they were spending 15-20 hours per month on scheduling logistics alone, and they were pretty sure they were losing potential clients who never followed through after the initial "how do I book?" inquiry.
What they needed
Through our initial audit, we mapped out the real requirements:
Multiple service types with different rules. Drop-in visits were 30 minutes with one pricing structure. Daily walks were 45-60 minutes with a different structure. Overnight stays had nightly pricing and required much more detailed intake. Each service type needed its own configuration — you can't treat a 30-minute drop-in the same as a 3-night stay.
Detailed intake per service. Every booking needed pet information: name, breed, age, temperament, feeding schedule, medication, vet contact, emergency contact. First-time clients also needed to provide their home address, entry instructions, and any alarm or security codes. This information needed to be collected before the appointment, not chased after it.
Deposits with flexible rules. The owner wanted a flat deposit for standard bookings and a higher deposit percentage for extended stays. They also wanted returning clients to be able to book without re-entering payment information every time.
Automated reminders. 24-hour and 2-hour email reminders for every booking, with service-specific content. The overnight stay reminder should include drop-off logistics. The walk reminder should confirm the pickup time.
Square integration. The owner was already established with Square for payments and didn't want to switch processors. The booking system needed to process deposits and payments through their existing Square account.
A branded experience. The owner had a nice website and a strong visual brand. They didn't want the booking page to look like a generic third-party tool. It needed to feel like a natural extension of their site.
What we built
The final system lives on the owner's website as a dedicated booking section. Here's what the client experience looks like:
Service selection. The client lands on the booking page and sees the available services: Drop-In Visit, Daily Walk, and Pet Sitting (overnight). Each one has a brief description, duration, and starting price. They pick the service they want.
Availability and scheduling. A calendar shows available dates and times for the selected service. The owner's real availability is reflected — if they're already booked for a time slot, it doesn't show. For overnight stays, the client selects a check-in date and check-out date. For visits and walks, they pick a single date and time.
Intake form. After selecting a time, the client fills out a form tailored to the service they chose. The overnight stay form is the most detailed — pet name, breed, feeding schedule, medication, vet info, emergency contact, home address, entry instructions, and any special notes. The walk form is lighter — pet name, breed, behavioral notes, pickup location, and leash/harness location. Returning clients see their previous information pre-filled and just need to confirm or update.
Deposit and payment. The next step collects payment through Square. For standard bookings, it's a flat deposit. For extended stays, it's a percentage of the total. The client enters their card info (or, for returning clients, confirms the card on file). The remaining balance is charged after the service is completed.
Confirmation. Immediately after booking, the client gets a confirmation email with all the details: service, date, time, pet name, deposit amount, cancellation policy, and what to expect. The booking also appears on the owner's dashboard and syncs to their Google Calendar.
Automated reminders. 24 hours before: a detailed email with the appointment info, any prep reminders, and a reschedule/cancel link. 2 hours before: a shorter reminder with just the essentials. Content varies by service type.
From the owner's side, the system provides a dashboard showing upcoming bookings, client history, and payment status. They can see their week at a glance, pull up a client's pet details before an appointment, and track which payments are completed versus pending. New booking notifications come in by email so they're immediately aware of incoming business.
What changed
The impact was noticeable almost immediately.
Time savings. The owner went from 15-20 hours per month of scheduling admin to about 2-3 hours. Most of that remaining time is reviewing new client intake forms and checking the weekly schedule — things that take minutes, not hours. The back-and-forth text conversations about availability basically stopped.
No-show reduction. With automated reminders and required deposits, no-shows dropped significantly. The owner went from a couple of no-shows per month to maybe one every other month. When someone does need to cancel, they use the reschedule link in the reminder email instead of ghosting, which means the slot gets freed up and can be filled.
More bookings. Within the first month, the owner saw an increase in total bookings. The new bookings were almost entirely from people who booked online in the evening or on weekends — clients who found the business on social media, saw the "Book Now" button, and converted on the spot. These were bookings that would have been lost under the old text-and-call system.
Better client experience. The owner started getting unsolicited positive feedback about how easy booking was. Clients mentioned it to friends when referring them. The professional booking flow, combined with the automated reminders and smooth payment process, elevated the perception of the entire business.
Returning client convenience. Regulars especially loved it. They could rebook in under a minute — their pet info was saved, their payment method was on file, they just picked a date and confirmed. Several clients started booking more frequently because the friction was gone.
What I learned from this build
Every custom project teaches you something. This one reinforced a few things I now bring to every build.
First, the intake form is more important than most people think. Collecting the right information upfront doesn't just save the owner time — it makes the service better. When you show up to a pet sitting stay and already know the feeding schedule, the medication needs, and where the spare key is, the client feels taken care of. That starts with the booking system.
Second, deposits change behavior. The owner was hesitant about requiring deposits at first — worried it would scare clients away. It didn't. Clients expected it. And the ones who balked at a $30 deposit were the same ones who would have no-showed anyway.
Third, the branded experience matters more than you'd think for a small service business. When the booking page matches the website, when the confirmation email looks professional, when every touchpoint feels intentional — it builds trust. Clients don't just book; they feel confident about the business they're booking with.
