Clinic inventory: consumables, expiry and reordering without a monthly count
Inventory is the one cost in a clinic that disappears without anyone noticing. A needle here, a filler vial expired there, an urgent order at a higher price because nobody saw the gloves run out. Here is how to run it without a Saturday stock count.
3 ways a clinic loses money on stock
First, unrecorded consumption. The session is delivered, the consumables leave the shelf, and nobody knows how much is left until it runs out.
Second, expiry. Filler, botox, vaccines and solutions have a date, and a vial that expires in the drawer costs its full price.
Third, the urgent order. Whatever runs out suddenly is bought from the nearest supplier at any price, and appointments are cancelled while waiting for it.
All three have one fix: the system knows what went out and when, instead of someone counting at month end.
Deduct with the service, not from a ledger
Every service on the price list has a consumption recipe: a laser session = two gloves, protective eyewear and gel. A filler injection = one vial, a needle and solution. When the session is recorded, the consumables are deducted on their own.
That gives you two things at once: a correct balance without a count, and a real consumables cost per session, per service and per doctor.
The difference between what was deducted and what is found at the periodic count is waste, and that number deserves to be read by room and by doctor.
Expiry by batch
Vials are not recorded as a count only, but by batch and expiry date. So "how many filler vials do we have" becomes the second question, and the first is "how many expire within 60 days".
The alert comes early enough to use the vial or return it to the supplier. Issue goes earliest-expiry first, which does not happen when staff take the vial nearest to hand.
For medicines and vaccines, batch recording is not an operational choice but a traceability requirement: when a product is recalled, you need to know which patient received which batch.
Reorder level: two numbers per item
The minimum, which is enough to last until the next order arrives. And the order quantity, which makes the order economical without filling the store with what will expire.
The first is calculated from weekly consumption and the supplier's lead time. When the balance drops below it, the item appears in a ready order list, with the supplier's name and last price. All the manager has to do is press send.
Consumables in pricing
Consumables cost per session is the first component of package pricing and the most neglected. When consumables are deducted with the service, the number is available without calculation: this session cost 38 SAR in consumables, this package 230 SAR.
When the supplier raises a price, the effect shows in the service margin the same week, not at year end.
Main store and branches
A centre with three branches has 4 stores: one main and one per branch. A transfer between them is a recorded movement with who sent and who received, not a bag in a car.
Each branch has its own reorder levels, because an aesthetics branch does not consume like a physiotherapy branch. The report shows waste and cost per branch, which explains why two branches have different margins on the same service.
The periodic count: confirmation, not discovery
The count does not disappear, but it changes. Instead of counting everything to find out what you have, you count a sample to confirm the system is right. Any difference gets explained: consumption not recorded, a service recorded with the wrong recipe, or something that walked out of the door.
A quarter of an hour a week on the expensive items replaces a day a month on everything.
Questions
Does a small clinic need inventory management?
If it uses filler, botox, vaccines or any expensive item with an expiry date, yes. One expired vial is worth months of subscription.
Who records consumption?
Nobody. It is deducted when the service is recorded, according to a consumption recipe set once per service. Only exceptions are recorded by hand.
How do I handle an item used in variable quantities?
The recipe carries the usual quantity, and the doctor adjusts it at the session if it differs. The gap between usual and actual is a report in itself.
Should I link the supplier to the system?
At least their name, last price and lead time per item. That is what turns an alert into a ready order.
What about medicines dispensed to the patient?
Deducted at dispensing and shown on the patient's invoice, by batch. That covers traceability and pricing at once.
How do I know the waste?
The difference between what the system deducted and what the periodic count found, per item and per room. A small recurring number deserves a question.
