Switching guide · AVImark is a Covetrus product

Switching from AVImark to a cloud PIMS

AVImark has run clinics for decades on a server in the back room. Here is what its owner's own documents say about the system and your data, what a managed move looks like day by day, and what changes on the first morning without the server.

Facts checked on the vendors' own pages, September 3, 2026 · written by the Bittsi team · sources at the end

Stay on AVImark if
  • Your server, backups and Windows updates are handled and you have no appetite for change this year.
  • You depend on a local integration or custom report that no cloud system has offered to rebuild.
  • Your team is fully trained and turnover is low, so the click cost is invisible to you.
Choose Bittsi if
  • You want the server, the backups and the after-hours IT calls gone, and the whole clinic in one browser system: records, hospital floor, anesthesia, dental, inventory, payments, messaging and the pet-owner app.
  • You want the migration done for you and verified row by row, live in 14 days, with staff trained by role.
  • You want to leave the way you came: month to month, your data exported free whenever you ask.
What Bittsi is

One system. Nothing to integrate.

Everything below is built into Bittsi and priced on one page. Enter it once and it is everywhere it needs to be: the charge posts and inventory moves the moment a treatment is logged. The only integrations are the ones only a lab or a card network can provide: IDEXX, Antech and Bittsi Pay.

What AVImark's own documents say

Not our opinion of the product. What its owner publishes, with the source next to each point.

Who owns it, and where they are going

Covetrus, taken private by Clayton, Dubilier & Rice and TPG in October 2022 at about $4 billion of enterprise value. A merger with MWI Animal Health, announced in February 2026, awaits regulatory approval and is not expected to close in Cencora's fiscal 2026. Covetrus's own cloud product, Pulse, launched in 2022 and reported more than 3,000 practices a year later. No end-of-life notice for AVImark has been published and we do not claim one; but a vendor's new investment tells you where its next decade of features will land.[1][2][7]

What you are maintaining

A server in the main hospital that, for multi-location use, "must be on a Windows Server Edition", set up by "a qualified technician, experienced in terminal services". The recommended-settings sheet asks for Microsoft Word 2021, 2019 or 2016 for documents, notes that Office 365 "does have known issues with Avimark" and that "Libre and Open Office no longer works properly", and says not to install Office on the database server.[5][6]

What the data terms say

Covetrus's Data Vault backup terms state that at cancellation the customer's access to data stored by the service may be permanently terminated. Your local database is yours to export; the hosted backup is not something to rely on after you leave.[4]

Why clinics move

The reasons we hear are the same every time: the server, the click count, remote access, and the modern gaps: no documentation AI, no clinical assistant, no built-in payments, no pet-owner app. None of those is a criticism of a system designed in a different decade; it is a description of what a clinic needs now.

Side by side, from the published record

Every AVImark cell carries a source number. “Not published” means the vendor does not say on the pages we checked; ask them, and get it in writing.

What AVImark does well

  • The largest self-reported installed base in the last published industry survey, more than 10,000 US practices in 2021, so most staff you hire will already know it.
  • A locally installed system keeps working when the internet does not.
  • Real multi-location capability through its Site feature, with a bi-directional IDEXX VetLab Station integration at the main hospital.
  • Candid technical documentation: the Site guide and the recommended-settings sheet say plainly what the system needs and what it cannot do.
  • Document Writer has been included since version 22.10, and a parent with more than 100,000 customers and a cloud successor, Covetrus Pulse.
  • Decades of practice history in a format that migration teams, ours included, know how to read.

What a switch actually looks like

The same plan for every clinic that moves to Bittsi, with a date and an owner on each step. It is written into the Switch Guarantee.

  1. 01Before you sign: one fixed quote and a sandboxWe size the migration from your current system and load a sandbox with your own records. You click around your real patients, not a demo clinic.
  2. 02Days 1 to 3: exportYour data comes out of the old system while it keeps running. Nothing changes for the front desk.
  3. 03Days 3 to 8: mapping and importClients, patients, visit history, prescriptions, reminders and balances, mapped field by field. Anything that cannot be mapped cleanly is archived read-only and labelled.
  4. 04Days 8 to 10: verificationEvery record checked against the source, row by row. You get the report.
  5. 05Days 10 to 13: training by roleShort sessions for the front desk, technicians and doctors on the parts they touch, not an all-day shutdown.
  6. 06Day 14: go-liveOn a lighter day, with your launch lead on call. The old system stays readable for reference until you retire it.

Questions clinics ask about AVImark and Bittsi

Can all my AVImark history move?

Clients, patients, full visit history, prescriptions, reminders and balances move and are verified row by row against the source. Anything AVImark cannot export cleanly is archived read-only in Bittsi, clearly labelled, so nothing is lost even when it cannot be mapped.

How long does it take?

About 14 days from kickoff to go-live for a typical clinic: export and mapping in the first week, verification and role-based training in the second, then a supported go-live on a lighter day.

Do we keep seeing patients during the switch?

Yes. AVImark stays available for reference until cutover, training runs in short role-based sessions, and the go-live is scheduled around your calendar.

What does the migration cost?

One fixed quote before you sign, based on your database size. It is included with annual billing and always included for founding clinics. There is no hourly billing.

Can we run AVImark and Bittsi side by side for a while?

Yes, and most clinics do for a few weeks. AVImark stays read-only for reference on the old server while Bittsi holds the live record. Nothing new is entered in AVImark after go-live, so there is one source of truth from day one.

What happens to the server?

It becomes a backup you keep for as long as your state's record-retention rule requires, and then a paperweight. Bittsi holds the live record and exports it free whenever you ask.
