Aesthetics Beauty Supplies Inventory: How to Set Reorder Levels

Running short on a product mid-treatment is one of the more avoidable problems in clinic management, yet it happens regularly when reorder levels are based on guesswork rather than actual data. Setting sensible reorder points across your aesthetics beauty supplies inventory takes a bit of upfront work, but it pays off in fewer emergency orders and less stock sitting unused on the shelf.

Build an accurate starting inventory

Before setting any reorder levels, you need a reliable picture of what's currently in stock. This means physically counting items, not relying on estimates or what an order history implies should be there.

For each product, record:

• Current quantity on hand
• Location within the clinic (useful for multi-room or multi-site clinics)
• Expiry date of each batch currently in stock

This baseline becomes the foundation for everything that follows. Without it, reorder calculations are built on assumptions rather than fact, and are far more likely to be wrong.

Measure consumption before setting quantities

Reorder levels should reflect how a product is actually used, not how much a clinic expects to use it. Look back over at least three months of usage, ideally longer, and calculate an average consumption rate per week or month for each product.

This step often reveals surprises. A treatment product assumed to be in high demand might show inconsistent usage tied to a handful of specific bookings, while a less "exciting" consumable might show steady, predictable use that makes it a far better candidate for a structured reorder point.

Calculate a practical reorder point

Once you know average consumption, the reorder point calculation becomes straightforward:

Reorder point = (average usage per day × supplier lead time in days) + safety stock

Lead time is how long it typically takes a delivery to arrive after an order is placed. Safety stock is a small buffer to cover unexpected demand or a delayed delivery, and doesn't need to be large for most items, a few days' worth of average usage is usually enough.

For example, if a clinic uses six units of a product per week (roughly 0.86 per day), and the supplier's typical delivery lead time is three days, the reorder point sits at around 2.6 units, plus a small safety margin, perhaps rounding to 4 units. When stock falls to this level, it's time to reorder.

Adjust for orders already placed and upcoming demand

Reorder points work best when they're checked against what's already in motion. If an order has been placed but not yet delivered, that stock should be considered when deciding whether a new order is genuinely needed, to avoid duplicate ordering. Similarly, if a clinic has upcoming bookings that will noticeably increase demand for a specific product, such as a promotional push on a particular treatment, it's worth temporarily adjusting the reorder point upward to account for it.

Create a repeatable stock-review routine

Reorder levels aren't a one-off calculation. Usage patterns shift as treatment popularity changes, new products are introduced, and clinic capacity grows or contracts. A simple, repeatable routine keeps reorder points accurate over time:

1. Conduct a physical stock count on a set schedule, such as monthly or fortnightly.
2. Compare actual usage against the assumptions used to set current reorder points.
3. Adjust reorder points where usage has meaningfully changed.
4. Flag any products approaching expiry that may need to be prioritised for use before reordering more.

Clinics that build this into a regular routine, rather than reacting only when stock runs low, tend to spend far less time on urgent, last-minute ordering.

Frequently asked questions

How often should reorder levels be recalculated?
Most clinics benefit from reviewing reorder levels monthly, or whenever a noticeable shift in treatment demand occurs.

What counts as a reasonable safety stock buffer?
This varies by product, but a few days' worth of average usage is typically sufficient for steady-demand items. Products with longer or less reliable delivery lead times may need a slightly larger buffer.

Should every product have a reorder point?
Setting reorder points is most useful for regularly used products. Occasional or highly seasonal items may be better managed through periodic review rather than a fixed reorder trigger.

What if usage is too inconsistent to calculate a reliable average?
For highly variable products, a shorter review cycle (checking stock weekly rather than monthly) tends to work better than a fixed reorder point.

A clear reorder system takes the guesswork out of restocking and helps avoid both shortages and unnecessary surplus. Once your stock review is complete, use it to prepare a focused replenishment order from IGO.
