Short answer: Most people who call a vet clinic and hang up without booking are never contacted again. A simple callback system fixes much of that: log every unbooked call with a reason, follow up within one business day, offer two specific appointment times, and check the numbers every week.
What happens to callers who don't book?
Two recent studies show how big the gap is.
- Patient Prism's Veterinary Patient Access Report (published 2 July 2026) looked at 568,309 calls to 384 veterinary locations on its platform in 2025. Of 195,186 real booking opportunities, 69,227 callers left without an appointment, and fewer than 1,000 of them got a callback (about 1.4%).
- The same data shows clinics booked roughly 8 in 10 returning clients but fewer than half of new ones. And 68.1% of lost callers were still deciding or couldn't find a suitable time.
- A peer-reviewed JAVMA secret shopper study called 5,053 general practices in six US states in early 2025. Callers got an appointment in 67.0% of attempts. The main failures were not reaching a person (15.1%) and holds longer than five minutes (8.2%).
Note that the first report comes from a vendor's own platform data, so treat it as a strong signal rather than an industry average.
Why does this matter for your clinic?
These callers already found you, chose you and picked up the phone. In the Patient Prism data, 82% of calls with a known source came through Google search, Google Ads or Google Business listings. So an unbooked call that nobody follows up is marketing spend you have already paid for. Most of those lost callers are new clients, the people a growing clinic needs most.
How do you set up a callback system? 5 steps
- Log every unbooked call. Record the caller, the pet and one reason: still deciding, no suitable time, price, service not offered, or couldn't get through.
- Set a callback deadline. We suggest the same day for calls during opening hours, and the next morning for voicemails and after-hours calls. The longer you wait, the more likely they've booked somewhere else.
- Match the follow-up to the reason. Use the table below, so each callback answers what actually stopped the booking.
- Offer two specific times. "Tuesday at 10 or Thursday at 4?" is easier to say yes to than "call us when you're ready".
- Review it weekly. Track three numbers: unbooked calls, callbacks made and appointments recovered. Compare them with your own first month.
What should you say for each reason?
| Reason they didn't book | What to do in the callback |
|---|---|
| Still deciding | Answer the question they had, explain what a first visit includes, then offer a time |
| No suitable time | Offer two openings, or add them to a waitlist and call when a slot frees up |
| Price | Explain what the fee covers and any payment options you genuinely offer |
| Couldn't get through | Call back quickly, and send a text if they don't answer |
| Service not offered | Refer them kindly and don't chase further |
What are the common mistakes?
- Waiting for them to call back. The data above suggests most won't.
- Making only one attempt. Try a call, then a text, or WhatsApp where your clients prefer it.
- Having no owner. Give one person the callback list each day.
- Pushing too hard. Stop when someone says no, respect opt-outs, and keep clinical advice with your vets, not reception.
Where does RevisitCare fit?
Many unbooked calls start with a phone nobody could answer. RevisitCare is an AI voice and WhatsApp front desk for pet businesses. It answers incoming calls and books appointments around the clock, including when your front desk is busy or the clinic is closed. If a caller has a medical question, it flags the conversation and offers a callback from your team, and its human-in-the-loop unified inbox lets staff take over with full context. It integrates with AVImark, Cornerstone and ezyVet for vet recall and follow-ups, and you can start free with 20 AI conversations and no credit card. If you're new to AI at the front desk, start with our 5-step plan for rolling out AI at a vet clinic.
FAQs
How quickly should a vet clinic call back someone who didn't book? As soon as you can. We suggest the same business day for calls during opening hours and the next morning for voicemails and after-hours calls.
How many unbooked vet callers get a callback today? Very few. In Patient Prism's 2025 platform data, fewer than 1,000 of 69,227 callers who left without booking were called back, about 1.4%.
Should we call or text callers who didn't book? Call first, then text if they don't answer. Use the channel your clients actually reply on, such as WhatsApp in markets where it is the norm.
Can an AI receptionist help with unbooked calls? Yes, for routine booking calls it can answer when your team can't. Keep medical questions, complaints and sensitive conversations with your staff.
