Veterinary Practice Management Software Comparison: Cornerstone vs AVImark vs ezyVet vs ImproMed

PIMS — practice management software — is the system a practice runs on for scheduling, medical records, invoicing, inventory and client communication: the day-to-day tool a practice manager lives in.

The four names this page compares are Cornerstone, AVImark, ezyVet and ImproMed.

What's easy to miss going in is that the names are less independent than they look: three of the four trace back to two companies.

Here is what the vendors' own pages establish as of this writing (all retrieved 2026-10-22).

Cornerstone and Neo are IDEXX products — both product pages sit on IDEXX's own software site. ezyVet markets itself as cloud veterinary software "backed by IDEXX" — ezyVet's own wording rather than a statement from IDEXX.

And the Covetrus pages we read sell AVImark and Pulse.

ImproMed is the one name our research couldn't pin to a company, which we come back to below.

None of this is hidden, but none of it is front and center in a sales pitch either — and it changes what questions are worth asking.

Laid out by the pages we read: IDEXX — Cornerstone and Neo on its own software site, plus ezyVet, which markets itself as "backed by IDEXX."

Covetrus — the pages we read sell AVImark and Pulse.

That's the entire verified map.

It's worth being precise about what that map doesn't include.

Our research found no public market-share figure for veterinary practice management software, so a "market leader" claim from any vendor or comparison site — this page included — needs to show its data before it counts for anything.

Two names under the same company roof aren't the same product, and sharing a company doesn't automatically mean they integrate seamlessly with each other — but the map is worth having on the table before you evaluate, for a few concrete reasons.

First, roadmap risk.

A company selling several products in the same category has to decide where new development goes.

Ask directly whether the product you're evaluating is still being actively developed, or whether the company is steering new customers toward a sibling product instead.

Second, procurement leverage.

If your practice already uses other IDEXX or Covetrus products — in-house lab equipment, pharmacy distribution, other software — ask whether that changes pricing, contract terms or support priority, in either direction.

Third, switching risk.

Moving from one IDEXX product to another, or one Covetrus product to another, may get framed by the vendor as an easier migration than moving to an outside competitor.

That may be true, but "easier for us to sell you" and "easier for your practice to execute" aren't the same claim — get the migration process described in writing rather than taking the framing at face value.

Strip out the feature grids and a PIMS comparison comes down to five factors: who stands behind it — the company attached to the product and where that product sits in the company's portfolio, which is the map above; hosting — where the software runs and who is responsible for it; integrations — whether it connects to the lab, imaging and payment processing you already run; exit terms — contract length, cancellation cost and the format your data leaves in; and workflow fit — whether the system matches how your team actually books, charts and bills.

One dimension can't be compared at all: market share, for the reason the callout above gives.

Hosting is the factor vendors do describe on their own pages, and our buying guide already sets those descriptions side by side.

This table sticks to the first factor instead: what the pages we read, retrieved 2026-10-22, establish about who stands behind each system.

Two names the table leaves out — ImproMed and Shepherd — aren't in it because the vendor pages we read for this comparison didn't establish who sells either system or how either is hosted, so there's nothing honest to put in a cell.

Ask those vendors directly and get the answer in writing.

One hosting gap is worth knowing before a Covetrus demo: the Covetrus pages we read didn't state a hosting model for AVImark or Pulse, and the only description of Pulse as a cloud PIMS in our research came from Provet — a competitor.

For the hosting side-by-side and the rest of the process — mapping workflows and integrations, pricing the full first year, and switching without losing staff — work through our veterinary practice management software buying guide.

Budget for the decision itself, too.

In AVMA's 2024 owner survey, 69.5% of practice owners felt they were keeping up with technology and 19.3% felt they were falling behind, with time and financial constraints the most common reasons for falling behind.

Both constraints argue for one disciplined comparison now rather than a reactive purchase later.

Search reviews of any system on this page and you'll meet three kinds of material: testimonials and case studies the vendor itself published, star ratings on general software-review sites, and word-of-mouth in practice-manager groups and forums.

All three are inputs.

None of them is a comparison.

The limits are structural, and reading more reviews doesn't fix them.

A vendor's case study is marketing — the vendor chose the practice, the quote and the metric.

Public reviews pool experiences from practices that can differ from yours in size, species mix, country and the support tier they pay for, and a review written a few years ago can describe a product that has since been rebuilt.

Review pools are also self-selected — people post when moved to, which is information, but not a representative sample.

So use reviews as a question generator, not a verdict.

Comb the negative ones for complaints that repeat — support responsiveness, an update that broke a workflow, difficulty getting data out — and turn each recurring theme into a line on the pre-signing checklist below.

Treat praise the same way: if reviewers rave about a feature, have the vendor show it running on your scenario, not theirs.

The closest substitutes for a review you can trust are the two things reviews can't give you: your own team driving a demo built on your workflows, and candid input from practices that resemble yours.

Both are steps in the evaluation at the end of this page, and our PIMS buying guide covers the full selection process.

The remaining two vendors in the table describe their products on their own sites: Digitail calls its software "cloud-based, AI-native veterinary practice management software," and Provet Cloud describes its PIMS as cloud-based.

Provet's site also names ezyVet and Covetrus Pulse as other cloud PIMS.

Go one question deeper, though, and the table runs out: our research didn't verify either company's ownership or corporate ties, so the "who actually owns this product today?" question from the checklist below goes to these vendors too.

Neither description above is a verdict on its own; it's one more input alongside the demo, the contract terms, and what your own team makes of the day-to-day workflow.

Every one of these has a written answer the vendor can put in front of you before you sign — and a vendor unwilling to answer one of them in writing is itself useful information.

A PIMS switch is a major operational project, which is exactly why it deserves the same diligence as a lease or a major equipment purchase — not a decision made off a single demo and a sales rep's slide about market share.
