ezyVet vs Cornerstone 2026: 6 Workflows Compared

Choosing a practice management system is a multi-year commitment. ezyVet and Cornerstone (IDEXX) are the two platforms most commonly shortlisted by established veterinary clinics — one built cloud-first with API depth, the other a mature on-premise system with decades of workflow muscle memory baked in. This comparison covers 6 core workflows, real pricing ranges, and the integration gaps that push clinics toward a separate automation layer regardless of which platform they choose.

TL;DR: ezyVet wins on cloud access, API integration depth, and modern client communication automation. Cornerstone wins on diagnostic integration speed for IDEXX in-house equipment, on-site data control, and legacy portability for clinics already in the IDEXX ecosystem. Neither platform automates the full post-visit follow-up and patient reactivation chain without external tooling.

Who This Comparison Is For

Who this is for: Veterinary clinics with 2–8 DVMs, annual revenue of $1.5M–$8M, and at least one staff member who manages scheduling software daily. You are either replacing an aging system (VIA, ImproMed, older Cornerstone versions) or selecting a platform for a new or acquiring practice.

Red flags: Skip both platforms if your clinic has fewer than 2 DVMs and under $600K in revenue — a lightweight tool like Vetspire may be sufficient. Skip this comparison if you are a large multi-site group (10+ locations); that evaluation requires enterprise licensing negotiations and a different integration architecture than this guide covers.

ezyVet vs Cornerstone: Platform Overview

ezyVet is a cloud-native practice management system built in New Zealand and now owned by IDEXX (the same parent as Cornerstone). Cornerstone is IDEXX's legacy on-premise platform, first deployed in the early 1990s and still the most widely installed veterinary PMS in North America. The shared IDEXX parent means both now share some diagnostic integrations — but their architecture, pricing models, and automation capabilities differ significantly.

According to AVMA (American Veterinary Medical Association, 2024), practices that offer online self-scheduling see a 23% reduction in front-desk phone volume during peak morning hours. Platform selection has direct operational impact from day one.

Workflow 1: Appointment Scheduling

ezyVet's appointment module includes a client-facing booking portal out of the box. Cornerstone requires a third-party integration (PetDesk, VetPort, or similar) to expose online booking. For clinics where online self-scheduling is a priority — particularly those serving younger pet owner demographics — ezyVet reduces friction faster.

Workflow 2: Medical Records and SOAP Notes

Cornerstone has a meaningful advantage for clinics whose diagnostic volume runs through IDEXX in-house equipment (Catalyst, ProCyte, Coag Dx). Results flow into Cornerstone records automatically without a middleware step. ezyVet handles IDEXX diagnostics via API, which works well but adds a configuration step and occasional sync lag of 2–5 minutes.

IDEXX in-house lab attachment speed: under 30 seconds in Cornerstone according to IDEXX (2025), versus an average of 2–5 minutes via API-connected systems like ezyVet.

For clinics using a third-party reference laboratory (Antech, Zoetis, regional labs), neither system has a built-in edge — both require the lab's integration module or HL7 configuration.

Workflow 3: Invoicing and Payment Collection

Both platforms generate invoices at discharge. ezyVet's estimate workflow allows digital client approval via SMS link — the clinic sends an estimate and the client taps to approve before the procedure begins. Cornerstone typically handles this via a printed or emailed estimate requiring verbal confirmation.

According to AVMA (2024), clinics that capture digital estimate approval before procedures report a 31% reduction in post-invoice disputes.

A worked example: a 3-DVM general practice in Ohio runs 55 appointments per week with an average invoice of $210. When a client checks in and the appointment.checked_in event fires in ezyVet, US Tech Automations triggers a pre-visit estimate SMS for appointments flagged "surgery" or "dental." The client approves the $680 estimate via a link before the procedure. Of 8 such procedures per week, this eliminates 2–3 post-discharge billing calls and reduces same-day write-offs by approximately $400–$600/month. For a full picture of how the estimate-to-invoice workflow connects, see US Tech Automations agentic workflows for veterinary practices.

Workflow 4: Client Communication and Retention

This is where ezyVet pulls ahead most clearly. Cornerstone's communication module was designed when email was the primary channel. Two-way texting, post-visit instruction delivery by SMS, and automated recall sequences are add-on integrations — each with its own licensing cost and sync delay. ezyVet builds these natively, with patient communication tied directly to the appointment and medical record.

Veterinary recall via automated SMS: 78% open rate vs. 22% for email according to Podium (2024). Clinics automating recall recover an average of $18,000–$45,000 per year in lapsed patient visits.

Workflow 5: Reporting and Analytics

Cornerstone's reporting is robust but designed for power users comfortable with query-based filtering. ezyVet's dashboard layer is more accessible for practice managers without a data background. Neither platform provides benchmarking against industry averages natively; that requires a third-party analytics tool (Covetrus Pulse, VetSuccess, or custom BI).

Workflow 6: Integration and API Access

ezyVet's open REST API and webhook support are the single biggest structural advantage for practices that want to add automation on top of their PMS. When a patient record updates, when an appointment is confirmed, or when an invoice is paid, ezyVet can fire a webhook to an external orchestration layer in real time. Cornerstone requires polling or vendor-specific connector tools, which introduces latency and complexity.

ezyVet REST API coverage: over 150 documented endpoints according to ezyVet (2025), covering appointments, patients, invoices, and clinical records.

Performance Benchmarks: Automation Impact by Workflow

The difference between a connected and a disconnected practice management stack shows up in measurable outcomes. The data below reflects industry benchmarks from practices using ezyVet or Cornerstone with various levels of automation layered on top.

These benchmarks reflect the compounding effect of layering communication automation on top of a functional PMS. Neither ezyVet nor Cornerstone delivers the "full orchestration" outcomes alone — that tier requires connecting the PMS to external communication, CRM, and billing tools via API.

According to Podium (2024), veterinary practices that automate post-visit recall reduce manual front desk reminder time by an average of 70% while increasing recall response rates by 2.5×.

DIY and No-Code Alternatives

Many clinics attempt to bridge ezyVet or Cornerstone gaps with Zapier or Make. Zapier handles straightforward appointment-to-reminder sequences well. But a 3-DVM clinic running 55 appointments per week with vaccine recalls, post-visit instructions, and payment follow-up sequences hits Zapier's per-task pricing quickly — roughly $200–$350/month for the task volume required, with no retry logic when ezyVet's webhook fires and Zapier's rate limit is exceeded mid-chain. US Tech Automations orchestrates these sequences at the workflow layer, with error handling and audit trails built in, rather than stitching individual zaps together at per-task cost.

When NOT to Use US Tech Automations

If your clinic runs under 20 appointments per week and your primary need is automated reminder texts, both ezyVet's native communication module and a standalone tool like PetDesk ($99–$199/month) are sufficient without adding an orchestration layer. US Tech Automations adds value when you need multi-step sequences (check-in → pre-estimate → post-discharge instructions → recall reminder) that span multiple platforms and require error handling. For billing software considerations, see best billing invoicing software for veterinary clinics.

US Tech Automations connects to ezyVet's REST API to run the post-visit discharge sequence: when the invoice.paid event fires, it triggers a discharge instruction SMS with the patient's specific treatment summary, schedules a 48-hour wellness check-in, and writes a follow-up task to the CRM record — without requiring staff to manually initiate each step. For Cornerstone practices, the same workflow runs via a polling connector that checks for status changes every 5 minutes. Review pricing options for veterinary automation to see which integration tier fits your practice size.

Glossary: Key Terms for Evaluating Veterinary Practice Management Systems

• ERA (Electronic Remittance Advice): An electronic version of the explanation of benefits sent from an insurer after a claim is processed. Practices with insurance billing need their PMS to post ERAs automatically — a feature Cornerstone handles natively for US payers.

• HL7: A healthcare data interoperability standard used to transfer clinical data between systems (e.g., lab results from a reference lab to the PMS). Both ezyVet and Cornerstone support HL7 connections for external labs.

• API (Application Programming Interface): A documented interface allowing external tools to read from and write to the PMS. ezyVet's REST API is publicly documented with 150+ endpoints. Cornerstone's API is available but vendor-gated, requiring IDEXX approval for each integration partner.

• Webhook: A real-time push notification sent by the PMS to an external system when a specific event occurs (e.g., appointment confirmed, invoice paid). ezyVet supports webhooks; Cornerstone does not natively.

• PIPEDA: Canada's Personal Information Protection and Electronic Documents Act, the primary federal privacy law governing how businesses collect, use, and disclose personal information. Jane is PIPEDA-compliant; Cornerstone's compliance focus is US-centric.

• Recall reminder: An automated communication sent to a client when a patient is due for a vaccination, wellness exam, or follow-up procedure. ezyVet includes recall automation natively; Cornerstone requires a third-party tool.

Frequently Asked Questions

Is ezyVet owned by IDEXX the same as Cornerstone?

Both are owned by IDEXX Laboratories, but they are separate products with different architectures. ezyVet is cloud-native, acquired by IDEXX in 2022. Cornerstone is IDEXX's legacy on-premise platform. They share some diagnostic integrations but have distinct codebases, pricing models, and feature roadmaps.

How much does ezyVet cost compared to Cornerstone?

ezyVet is typically priced per user per month at $250–$450/DVM/month depending on modules selected. Cornerstone is typically priced via a perpetual license plus annual maintenance, with initial costs of $8,000–$25,000 depending on practice size. ezyVet's total cost of ownership is often lower at the 5-year mark for smaller practices due to no server infrastructure requirements.

Can Cornerstone users access records remotely?

Yes, but it requires a VPN connection to the on-premise server or deployment on a hosted server environment (which IDEXX offers as a managed option). ezyVet provides full cloud access via browser or mobile app without VPN setup.

Which system is better for multi-location veterinary practices?

ezyVet scales more cleanly to multi-location because all locations share a single cloud database, allowing shared patient records and centralized reporting. Cornerstone multi-site setups require server replication and more complex IT infrastructure.

What happens to Cornerstone data if we migrate to ezyVet?

IDEXX provides a migration path between Cornerstone and ezyVet since both are IDEXX products. Migration typically takes 6–12 weeks and includes patient demographics, medical history, and invoice records. Prescription history and some custom report templates may require manual recreation.
