When the clinic closes, the phones don't stop. Pets get sick at 9 p.m. and anxious at 2 a.m., and every call carries a decision: come in, wait, or go somewhere else. The question is who makes that decision, and with what information.
For most practices tonight, the answer is nobody. The call rolls to an answering service, which takes a message and a phone number and leaves the client to decide. The client decides to go to the ER. The ER treats the pet, sends a bill, and gains a client your practice may never see again.
Where the number comes from
The $88,000 figure gets quoted a lot, and it deserves a transparent origin. It starts with call volume. A typical practice with four full-time veterinarians receives 40 to 80 after-hours calls a month. Take the middle of that range: 60 calls.
Then the conversion rate. When an after-hours call is handled by a licensed RVT, VetWise client outcomes show about 70% of those calls convert into appointments at the practice. Not every call becomes a visit. The 70% comes from real client outcomes, and real outcomes include the calls that don't convert.
The arithmetic: 60 calls a month, 70% convert, 42 appointments. At a $175 average appointment value, in line with industry benchmarks, that's $7,350 a month in appointment revenue the practice would otherwise send down the road. Twelve months later: $88,200.
60 x 0.7 = 42. 42 x $175 = $7,350. Times twelve, $88,200.
What the ER actually costs you
The ER visit itself isn't the main cost, even though it's the visible one. The main cost is the client. A client who shows up at an unfamiliar ER at 2 a.m., pays an unfamiliar bill, and gets care from an unfamiliar team is a client in motion. Some of them come back to you. Many don't, and the ones who don't take their annual exams, their vaccines, and their refill requests with them.
There's a second cost that never shows up in a ledger. The client called you first. They called because they trust you. When nobody answers, that trust gets tested at the worst possible moment, and no message slip captures it.
What a triage line changes
A licensed RVT answers as your practice, works from your triage protocols, and makes the decision an answering service can't: how urgent is this, really?
The routine case gets talked down, educated, and booked into your morning. The urgent case gets seen before it becomes an emergency. The true emergency gets directed to your ER partner with instructions and a heads-up. In every lane, the client experiences a clinical conversation with their practice instead of a message slip.
The revenue impact follows the behavior. The 70% conversion doesn't come from magic; it comes from clients who were told "we'll see you at 8 a.m." instead of "the clinic is closed." When the appointment books into your calendar while the client is still on the phone, that revenue is captured in the moment.
The honest caveat
Not every after-hours call is recoverable, and pretending otherwise is how practices get burned by unrealistic ROI promises. Some calls are true emergencies and should go to the ER. Some clients will choose the ER regardless of how well you answer. The 70% figure is an observed outcome. What any single practice gets depends on its call volume, its market, and its protocols.
The math scales to your practice, though. Half the call volume, half the number: a two-vet practice working the same assumptions is looking at roughly $44,000 a year. Our ROI calculator runs the numbers on your actual inputs, and it takes about a minute.
What your team gets back
The quieter benefit is the one your staff feels on Monday. No one starts the day wondering what happened overnight, because the records are waiting. No one rebuilds a conversation from a voicemail, because every call produced a chart-ready note. The practice keeps the client, keeps the revenue, and the people who work there get their nights back.
How VetWise handles it
Every VetWise line is staffed by licensed RVTs with ten-plus years of experience, answering as your practice under the triage protocols your team writes. Routine calls book into your schedule; emergencies route to your ER partners; and where the VCPR laws of your state or province permit, a licensed veterinarian steps in when the pet needs care that night. The mechanics of a call, from first ring to chart-ready record, are covered in what actually happens on an after-hours line, and the legal side of what an RVT can do is in our scope-of-practice guide.
FAQ
Is $88,000 realistic for my practice? It depends on your call volume. The figure assumes 60 after-hours calls a month, 70% conversion, and a $175 average appointment value. Run your own numbers in the ROI calculator; the assumptions are right there on the page.
I'm a two-vet practice. What's my number? Roughly half, on the same assumptions: about $44,000 a year. The math is linear in call volume, and the calculator adjusts for your actual FTE count and call volume.
How many after-hours calls does a typical practice get? 40 to 80 a month for a four-vet practice, per the calculator's model. It varies by location, client base, and how well your daytime team books follow-ups.
Do clients really come in after an after-hours call? VetWise client outcomes show about 70% of clinically handled calls convert to appointments. The behavioral reason is simple: the client was told what to do next and given a time to come in.
What's the difference between a triage line and an answering service? An answering service takes a message. A triage line assesses urgency, educates the client, and books the outcome. The revenue difference is the 70% that books into your calendar instead of walking to the ER.
How fast can we start? The line can be live in under a week. Protocol writing is the one thing that takes real time, and it's the part worth taking time on.
