In many veterinary practices inventory is the largest expense after staff, yet it is the one managed with the least method. Drugs ordered by feel, unmonitored fridges, boxes that expire at the back of a drawer, capital locked up in slow moving products: these are common situations that erode the margin without anyone really seeing them, because they never show up on a single bill but dissolve into a thousand small wastages. Governing stock does not mean turning the practice into an industrial warehouse; it means applying a few repeatable criteria that reduce expiries, avoid stock-outs exactly when a lifesaving drug is needed, protect the cold chain and make every batch traceable in case of a recall. This page does not cover the controlled drugs register, which has its own rules, but the routine management of drugs, vaccines and consumables. The aim is practical: free up cash and cut errors with simple habits.
Reorder points and product classification
The heart of good management is to stop ordering by feel and define, for each product, a level below which you reorder and a quantity to reorder. But not every product deserves the same attention: a few items make up most of the value and the consumption, and that is where control should be concentrated.
| Category | Characteristics | How to manage it |
|---|---|---|
| High value or high use | Few products that weigh heavily on spend and turnover | Calculated reorder point, frequent counting, reliable supplier |
| Medium value or use | Regularly used but less critical products | Simple reorder point, periodic check |
| Low value or low use | Many items that weigh little | Minimum stock, batch reordering, rare counting |
| Lifesaving drugs and antidotes | Rarely used but indispensable in an emergency | Always available, expiry monitored separately, never go below threshold |
| Perishable and cold chain | Vaccines and refrigerated drugs | Orders calibrated to real use, dedicated temperature management |
The reorder point accounts for how much you use on average and how long the supplier takes to deliver, with a small safety margin for the unexpected. Setting it once and reviewing it periodically avoids both stock-outs and excess. Many veterinary practice systems let you set it and generate automatic alerts when stock drops: using them reduces mental load and errors.
Expiry, batches and the cold chain
Three risks deserve a written procedure, because they touch cost, quality of care and legal responsibility at once: managing expiry dates, batch traceability and controlling the temperature of refrigerated products.
Apply first expiry, first out
Whoever restocks the shelf puts new products behind and those with the nearest expiry in front, so what is about to expire is always used first. It is the single measure that cuts expiries the most.
Check expiries at fixed intervals
A monthly review of shelves and fridge catches products near expiry in time to use or return them. Flag those expiring within a few months and plan their use.
Record batches of traceable products
For vaccines and recall prone drugs, note the batch against the patient. In a batch recall you can quickly trace the animals involved and warn owners without reconstructing everything by hand.
Monitor the fridge temperature
A dedicated drug fridge, with a min-max thermometer or continuous logging, protects the cold chain. Check and record the temperature daily and define what to do in case of a spike or a power cut.
Define disposal of expired drugs
Separate expired products from active stock immediately, to prevent accidental use, and dispose of them according to the rules on clinical and pharmaceutical waste, documenting the operation.
Making the process sustainable over time
A stock management system only works if it survives busy days, when the temptation is to skip the checks. The key is to keep it light, assign it to someone and build it into the tools already in use, rather than an extra task that depends on goodwill.
- Assign clear responsibility: one person who owns the stock, with a deputy, instead of a diffuse task that belongs to no one.
- Use the practice system you already have: automatic deduction on use, reorder alerts and turnover reports reduce manual work.
- Set a periodic review: a fixed monthly slot for expiries, stock levels and reordering prevents problems piling up.
- Measure a few indicators: stock value, annual expiries, number of stock-outs. If they improve, the system works.
- Revise reorder points when consumption changes: new therapies, seasonality and price changes shift the thresholds.
The goal is not accounting perfection but balance: always having what you need, wasting as little as possible and not locking up cash needlessly. Even a lean approach, if consistent, produces visible results on margin and service quality within a few months.
Frequently asked questions
- How often should I take stock inventory?
- A full inventory once or twice a year remains useful for accounting, but on its own it is not enough to govern stock. Better to pair it with more frequent, targeted checks: a monthly review of expiries and levels on high value and perishable products, and a rolling count that over the year covers everything without halting the practice. Many practice systems keep stock current in real time through automatic deduction, reducing the need for extensive manual counts.
- How do I calculate a drug's reorder point?
- The reorder point starts from two figures: how much of that product you use on average over a given period and how many days the supplier takes to deliver. Multiplying the average daily use by the delivery days gives the quantity you need to cover the wait, to which you add a safety margin for the unexpected and for peaks. When stock drops to that level, you reorder. It is worth calculating carefully on high value or critical products and more simply on the rest.
- Why is recording vaccine batches important?
- Because in a batch recall or an adverse reaction report you must be able to trace quickly which animals received that product. Linking the batch to the patient at the moment of administration lets you, if a recall arrives, identify and warn the owners involved within hours instead of reconstructing everything by hand. It is also legal protection and a traceability requirement that a well used practice system makes almost automatic.
- What do I do if the drug fridge loses power?
- You need a procedure decided in advance, not improvised in the moment. Keep the fridge closed as much as possible to hold the temperature, note the start time and the length of the outage and check with a min-max thermometer whether and by how much the temperature left the range. On restoration, compare the recorded values with the manufacturer's guidance to determine which products remain usable. If in doubt about vaccines or sensitive drugs, contact the supplier or manufacturer before using them.
What to do next
Treat inventory as a process, not an unavoidable cost: first measure annual expiries and the value of dead stock to make the losses visible, then define reorder points for high value and critical products and let the practice system raise the alerts. Apply first expiry, first out, check expiries and fridge temperature at fixed intervals, record batches for recalls and give stock responsibility to one named person. With a few indicators tracked over time, you free up cash, cut waste and prevent stock-outs exactly when they matter.
