Nearly everything on your shelves — drugs, vaccines, consumables, much of your equipment — arrives through a veterinary distributor. For a new practice, distributors are also an underappreciated resource: they run startup programs, extend payment terms, and their reps know your local market. Here’s how the system works and how to set it up well from the start.
The landscape: fewer, bigger players
US veterinary distribution has consolidated hard. Covetrus agreed to acquire MWI Animal Health in a $3.5B deal that reduces nationwide distributors of veterinary pharmaceuticals and supplies to two — the combined Covetrus–MWI, and Patterson Companies. Regional and specialty distributors (Midwest Veterinary Supply, Victor Medical, and others) still serve many markets, often with strong service on specific categories. Verify the current landscape when you open accounts — consolidation is ongoing and program details shift with it. What this means practically: you have limited leverage as a single new clinic, but distributors compete hard for new practices because a clinic’s first distributor usually keeps most of its business for years. Use that window.
Opening accounts
Expect to provide: your business entity details and EIN, state veterinary license (premises license where applicable), DEA registration for controlled substances, and a credit application. Start the paperwork 2–3 months before opening — DEA-linked account setup and first controlled-substance orders take longer than general supply. Open accounts with at least two distributors even if one will be primary. You’ll want a fallback for backorders (chronic in veterinary supply), a price check, and access to items one house doesn’t carry.
Startup programs: real money, ask for them
Both major houses court new practices. MWI runs new-practice startup programs that defer payment on the large opening orders — pushing due dates out and splitting the cost into the months when the clinic has actual revenue. Patterson pairs deferred-payment plans for new practices with financing on large equipment purchases. Your opening pharmacy-and-supply order is $20,000–$40,000 (see our pharmacy stocking guide); deferring it meaningfully protects opening working capital. These programs aren’t always volunteered — ask each rep directly what their new-practice package includes.
The primary-vendor decision
Distributors offer better pricing tiers in exchange for share-of-wallet — a primary vendor agreement typically commits ~80%+ of your purchasing in return for discounts and rebates. For a new practice the honest advice is: take the startup program, but delay signing a long primary-vendor commitment until you’ve run 6–12 months and know your purchasing pattern. Once you have volume data, negotiate from it (our companion article covers distributor negotiation in detail). Also weigh a buying group/GPO membership, which pools small-practice volume for better pricing — often the bigger lever for independents (see our GPO guide).
Working the relationship
Your distributor rep visits regularly and knows things you’ll want: which local practices are expanding, what equipment is coming off lease, current manufacturer promotions and vaccine programs. Treat the rep as a market-intelligence channel, not just an order-taker. At the same time, keep discipline: reps are compensated on your volume, so every “special” still deserves a second-source price check, and your inventory system — not the rep’s suggested order — should drive purchasing (see our inventory management guide).
What distributors don’t cover
Some manufacturers sell certain products direct-only or through restricted channels (some vaccines, some parasiticides with brand-integrity programs); reference labs and diagnostics companies typically have their own reps and agreements; and compounded medications come from compounding pharmacies. Your supply chain will have four or five legs — the distributor is just the biggest one. Set-up checklist: accounts open at two houses 8–12 weeks out · startup/deferred-payment program confirmed in writing · DEA-linked ordering tested before opening · electronic invoicing wired into your accounting from day one · a standing weekly order day so purchasing becomes routine, not reactive.
