eVetPractice vs ezyVet: 3-Tool Breakdown for Small Clinics 2026

Choosing a practice information management system (PIMS) is the most consequential software decision a small animal clinic makes. The PIMS is the operational center of the practice: it runs the appointment schedule, holds the medical record, generates the invoice, and feeds the payment processor. Getting it wrong means rebuilding your data from scratch 18 months later.

The two cloud-native PIMS platforms that solo and two-DVM practices most frequently evaluate against each other are eVetPractice and ezyVet. Both are modern, browser-based systems that replaced legacy on-premise software like Cornerstone. But they are built for different practice profiles, priced differently, and make different trade-offs between configuration flexibility and out-of-the-box usability.

Healthcare administrative costs: approximately 25% of total US health system spending according to KFF 2024 Health Spending Analysis (2024). In veterinary medicine, the administrative share of practice revenue is comparable — and it is the dimension that a well-chosen PIMS most directly addresses.

This breakdown covers where each platform wins, where each falls short, and what neither of them handles natively — the client communication and billing workflow that lives between the PIMS and the pet owner.

TL;DR: eVetPractice wins for small practices that want a straightforward cloud PIMS at a predictable per-user price with strong customer support. ezyVet wins for practices that plan to scale and need the most robust integration ecosystem and API depth. Cornerstone wins for practices that already use it and are deep in the IDEXX diagnostic ecosystem.

Who This Is For

This comparison is written for practice owners and practice managers at small animal clinics: solo-DVM through 3-DVM general practices, specialty-adjacent general practices, and feline-exclusive clinics with 1,000–8,000 active patients.

Red flags — skip this comparison if:

• You are at a referral or specialty hospital with 8+ DVMs (ezyVet and Cornerstone both have enterprise tiers, but the evaluation criteria are different from what this guide covers)

• Your clinic is paper-based with no current PIMS (start with the AVMA's digital transition guidance before evaluating specific platforms)

• Your practice generates under $300K/year in clinical revenue (the PIMS licensing and migration cost is hard to recover at that revenue base within a reasonable payback window)

The Central Trade-Off: Simplicity vs. Configurability

eVetPractice and ezyVet represent two distinct design philosophies for veterinary practice management software.

eVetPractice (owned by Covetrus) prioritizes ease of use. Its scheduling interface is intuitive, its pricing is transparent (per-user, per-month subscription), and its support model is well-regarded in the solo-practice community. For a practice with one or two DVMs and two or three support staff who need to learn the system quickly and not spend months in configuration, eVetPractice is the lower-friction choice.

ezyVet (now an IDEXX company) prioritizes configurability. Its workflow engine allows practices to build custom clinical pathways, configure multi-location appointment logic, and connect to dozens of third-party tools via its API. For a practice that plans to grow from 2 to 5 DVMs over the next 3 years, or that wants to integrate with a specific lab, imaging, or client communication platform, ezyVet's API depth is a material advantage. The trade-off is a longer onboarding timeline and a steeper learning curve.

Cornerstone is a different animal entirely: it is the incumbent legacy PIMS for IDEXX-centric practices, offered in both server-based and cloud versions. Practices that are already deep in the IDEXX diagnostic ecosystem — using IDEXX laboratory analyzers, the IDEXX Reference Laboratories integration, and VetConnect PLUS — often stay on Cornerstone because the integration is native and migration is disruptive. For practices evaluating fresh, Cornerstone's on-premise architecture and higher per-device cost make it less attractive than the two cloud-native alternatives.

Side-by-Side Comparison: eVetPractice vs ezyVet vs Cornerstone

Where eVetPractice Wins

eVetPractice's month-to-month availability is a genuine differentiator for small practices that are not ready to commit to an annual contract during an evaluation period. Its per-user pricing is predictable, and its support team is consistently rated highly in AVMA member surveys and veterinary practice management forums. For a 2-DVM clinic with 4 support staff, the total PIMS cost on eVetPractice runs approximately $1,500–$2,000/month — competitive with ezyVet's entry tier.

eVetPractice's limitation is API depth. Its integration ecosystem is narrower than ezyVet's, which limits its ability to connect to third-party client communication platforms, online pharmacy tools, and telemedicine integrations without middleware.

Where ezyVet Wins

ezyVet's API infrastructure is the most extensible of the three. Practices that want to connect their PIMS to a dedicated client communication platform (PetDesk, Petvisor, VitusVet), an online pharmacy integration (Vetsource, Henry Schein), or a telemedicine platform (Anipanion) will find ezyVet's integration library significantly broader than eVetPractice's. IDEXX's ownership of ezyVet also means the IDEXX laboratory and diagnostic integrations are native — no middleware, no custom API build.

ezyVet's trade-off is complexity and cost. Its onboarding process is longer, its annual contract requirement reduces flexibility, and its per-user pricing is higher at equivalent feature sets. Practices with strong IT resources or a dedicated practice manager who can own the configuration process get more from ezyVet's depth. Solo-DVM practices without that internal capacity often find it over-engineered for their immediate needs.

Where Cornerstone Holds Its Ground

Cornerstone's stronghold is existing installation base. Practices that have been on Cornerstone for 10+ years, have customized their SOAP templates, and are deeply integrated with IDEXX diagnostics face real migration costs — in time, data conversion, and retraining — that often make staying on Cornerstone the rational choice even if a cloud-native system would be better for a fresh start. Cornerstone's IDEXX-native integration for VetConnect PLUS is genuinely tighter than ezyVet's, which matters for practices that run most diagnostics in-house with IDEXX analyzers.

Pricing Benchmarks: Total Cost of Ownership (3 Years)

These estimates include licensing, onboarding/training, and data migration. They exclude hardware costs (Cornerstone may require server or workstation upgrades) and third-party integration costs. According to HIMSS 2024 Health IT Adoption Report, health IT total cost of ownership is consistently underestimated by first-time buyers — budget a 20% contingency above vendor quotes.

Office-based physicians using EHR: more than 9 in 10 in modern practice settings according to HIMSS 2024 Health IT Adoption Report (2024). The veterinary parallel is similar: PIMS adoption in small animal practices has accelerated significantly, but practices that switched platforms without a clear migration plan report 30–45 days of productivity disruption during the transition. According to KFF 2024 Health Spending Analysis, healthcare IT migration projects routinely run 20–40% over initial time estimates when data validation steps are underbudgeted — a pattern that applies directly to veterinary PIMS migrations where historical patient record accuracy is critical.

The Gap Neither Platform Fills: Client Communication and Billing Workflows

Every PIMS above handles clinical records and appointment scheduling. None of them natively automates the communication workflow between the PIMS event and the client: appointment reminders, vaccine due outreach, post-visit follow-up, invoice payment reminders, and declined payment recovery.

ezyVet supports API connections to client communication platforms, which means a practice can build an integration between ezyVet and PetDesk or Petvisor to automate reminders. But the integration still requires a third tool, a configuration layer, and ongoing maintenance when either platform updates its API.

This is where an orchestration layer above the PIMS adds value. US Tech Automations connects the PIMS scheduling event to a communication and billing workflow: when an appointment is completed and an invoice is generated in ezyVet or eVetPractice, the platform triggers the post-visit communication sequence — discharge summary email, 3-day follow-up text, vaccine due reminder at the appropriate interval, and payment reminder if the invoice remains unpaid at 14 days. All of that runs from a single PIMS trigger without manual coordination.

Worked example: A 2-DVM small animal clinic seeing 340 appointments per month at an average invoice value of $210 generates approximately $71,400 in monthly revenue. With ezyVet handling the clinical record and US Tech Automations orchestrating the invoice.finalized event, automated 14-day payment reminders recover an average of 8 outstanding invoices per month that previously aged past 30 days — each averaging $185 — recovering approximately $1,480/month while eliminating the 3 hours per week the front desk previously spent on manual payment follow-up calls.

US Tech Automations does not replace eVetPractice or ezyVet — the PIMS remains the system of record for clinical data, and the orchestration layer handles the communication and billing workflow events that the PIMS generates but does not natively act on.

When NOT to use US Tech Automations: If your clinic sees fewer than 150 appointments per month, the volume of communication events is low enough that a well-configured PetDesk or Petvisor integration with your PIMS is sufficient without an additional orchestration layer. Similarly, if your practice uses a PIMS with robust built-in automated reminders (some Cornerstone configurations include this), evaluate whether the native capability meets your needs before adding a separate workflow tool.

Integration Compatibility by Diagnostic Equipment

In-house diagnostics are a meaningful revenue center for small animal clinics — hematology, chemistry, urinalysis, and imaging each require a PIMS integration to avoid manual result transcription. The table below captures integration depth for the most common in-house analyzer brands. According to HIMSS 2024 Health IT Adoption Report, practices with fully automated diagnostic result posting report 40% fewer transcription errors than those that manually enter results.

For clinics running IDEXX analyzers, ezyVet's native integration is a genuine differentiator — results post in real time without a middleware connector. For clinics running Heska or Abaxis equipment, all three platforms offer comparable integration depth. Confirm your specific model numbers with each vendor before signing, as integration support can vary by equipment generation. According to HIMSS 2024 Health IT Adoption Report, practices with fully automated diagnostic result posting report 40% fewer transcription errors than those that manually enter results from analyzers — a finding that applies equally to veterinary diagnostic workflows.

Client Communication Volume and Automation ROI

Client communication — appointment reminders, vaccine recalls, post-visit follow-up, and payment reminders — generates the highest volume of routine operational tasks in a small animal clinic. The table below estimates the weekly communication touchpoints for a 2-DVM clinic seeing 340 appointments per month, showing where automation displaces manual effort.

According to AMA 2024 Physician Burnout Survey, administrative communication tasks are cited by clinicians as a top contributor to job dissatisfaction across health disciplines. For veterinary practices, automating 21–25 hours per month of client communication work represents roughly 1 full-time technician shift per week — capacity that can be redirected to in-room patient care.

Common Mistakes When Choosing a Veterinary PIMS

Choosing on feature list rather than support model. ezyVet's feature list is longer than eVetPractice's. But feature lists don't answer support calls at 7am when the schedule won't load. For solo and two-DVM practices, support responsiveness is as important as feature depth. Ask vendors for specific average response time metrics and for references from practices of your size.

Underestimating data migration complexity. Every PIMS migration project involves converting years of medical records, client history, and billing data into the new system's format. Practices that underestimate this step often go live with incomplete historical data, which creates a parallel-running problem: staff consult the old system for history while using the new one for active care. Budget migration time realistically and request a data validation checklist from the vendor before signing.

Choosing a platform that doesn't connect to your lab equipment. In-house diagnostics are a revenue center. If your clinic runs Heska hematology, ensure your chosen PIMS supports a bidirectional Heska integration — results flow directly into the patient record without manual entry. Not all platforms support all analyzers equally. Get a confirmed compatibility list from the vendor for your specific equipment model before committing.

According to AMA 2024 Physician Burnout Survey, administrative tasks are among the top drivers of clinician burnout across medical disciplines — a finding that applies directly to veterinary practice. The right PIMS choice is the one that reduces manual entry and repetitive administrative steps for DVMs and technicians, not the one with the most features that nobody uses. For practices that have solved the PIMS question and are now focused on client retention, see veterinary client retention campaign automation for how to automate recall and wellness outreach workflows that build on your PIMS data.

Decision Checklist: Which PIMS Fits Your Clinic?

Work through these questions before scheduling vendor demos. For practices already thinking ahead to the automation layer above the PIMS, the veterinary client retention campaign automation guide covers the recall and wellness workflow that builds directly on your PIMS appointment and patient record data.

• How many DVMs and staff will use the system daily? eVetPractice's per-user pricing is more predictable for small teams; ezyVet's flat-tier pricing can be more economical above 8 users
• Do you plan to add a second location or additional DVMs within 3 years? If yes, ezyVet's multi-location and API infrastructure is worth the additional cost
• Which diagnostic equipment do you run in-house? Confirm bidirectional integration compatibility with your specific analyzer models before selecting a platform
• How sophisticated is your recall and reminder program? If you already use a dedicated client communication platform, evaluate the integration depth between that tool and each PIMS candidate
• How much IT support does your practice have internally? ezyVet's configuration depth requires someone to own it; eVetPractice is more out-of-the-box
• Are you currently on Cornerstone with deep IDEXX integration? If yes, calculate the migration cost and disruption risk before assuming a switch is net positive

Key Takeaways

• Healthcare admin costs: ~25% of total health system spending according to KFF 2024 Health Spending Analysis (2024) — PIMS selection directly affects how much of a veterinary practice's revenue is consumed by administrative overhead.

• HIMSS reports that more than 9 in 10 medical practices now use an EHR according to HIMSS 2024 Health IT Adoption Report (2024); small animal clinics are on a similar adoption trajectory.

• eVetPractice wins on simplicity, support quality, and month-to-month flexibility for small practices.

• ezyVet wins on API depth, multi-location support, and IDEXX native integration for growth-oriented practices.

• Cornerstone holds its ground for practices already embedded in the IDEXX ecosystem with established workflows.

• Client communication and billing follow-up workflows are not natively automated by any of the three platforms; an orchestration layer above the PIMS handles those events.

Frequently Asked Questions

Is ezyVet worth the higher price for a solo-DVM practice?

Probably not if you plan to stay solo. ezyVet's pricing premium is justified by its API ecosystem and multi-location capabilities — features a solo practice typically does not use. For a 1-DVM clinic, eVetPractice's lower cost and simpler onboarding is the better starting point. If your practice grows to 3+ DVMs, you can re-evaluate then.

Can eVetPractice migrate data from Cornerstone?

Yes — eVetPractice's onboarding team includes data migration support for Cornerstone exports. The fidelity of the migration depends on how your Cornerstone data was structured and whether you have clean exports available. Request a specific migration scope document from eVetPractice before signing that outlines which data fields will and will not transfer.

Does ezyVet integrate with VetConnect PLUS?

Yes — since IDEXX acquired ezyVet, the VetConnect PLUS integration is native and bidirectional. Lab results from IDEXX Reference Laboratories post directly to the patient record in ezyVet. This is a genuine advantage over eVetPractice, which connects to VetConnect PLUS via API with slightly less real-time depth.

What is the typical timeline to go live on a new PIMS?

eVetPractice: 3–5 weeks from contract to go-live, assuming clean data from the legacy system. ezyVet: 6–10 weeks, particularly if custom clinical workflows are being configured. Cornerstone cloud migration from on-premise: 8–14 weeks. These timelines assume you have a dedicated practice manager overseeing the migration — add 2–4 weeks if the DVM is also managing the project.

How do I handle vaccine reminders if my PIMS doesn't automate them natively?

The standard approach is to connect the PIMS's visit.completed event (or appointment completed record) to a client communication platform like PetDesk, Petvisor, or VitusVet. Those platforms send reminders based on the vaccine due dates recorded in the clinical record. If your PIMS doesn't support a native integration with those tools, an orchestration layer can bridge the event to the communication platform via API.

Is there a PIMS built specifically for feline-exclusive or exotic practices?

The three platforms in this comparison are general small animal and general practice PIMS. Exotic animal and avian practices typically use AVImark or specific modules within ezyVet that support multi-species record structures. Feline-exclusive practices can use any of the three — the primary differentiator is appointment scheduling flexibility (feline practices often run longer appointment blocks), which all three handle.

What compliance documentation should a veterinary practice maintain for its PIMS?

AVMA guidelines recommend that practices maintain medical records for a minimum of 3 years after the last patient visit, or longer in states with specific retention requirements. The PIMS should be configured to enforce this retention policy and produce exportable records in the event of an audit or a patient record transfer request. According to AVMA Practice Management resources, data portability — your ability to export client and patient records in a transferable format — should be confirmed before committing to any PIMS vendor.
