Inventory management for Shopify medical supply stores

The inventory problems medical supply stores run into

• Lot and expiry tracking. Many items (gloves, wound dressings, test kits, incontinence supplies) carry expiry dates, and FIFO rotation matters more than in most retail categories.
• Wide SKU spread with inconsistent case packs. A single supplier might sell gloves in cases of 1000 but bandages in boxes of 50, so rounding orders to the right pack size by hand is slow and error-prone.
• Mix of fast movers and slow, high-value items. Daily disposables (gloves, masks) move constantly while mobility aids or diagnostic devices sell occasionally but tie up more cash per unit.
• Backorders and allocation from manufacturers. Some medical suppliers ration popular items during shortages, so lead times can swing unpredictably and orders may arrive partial.
• Regulatory and brand substitution limits. Customers and clinics often require a specific brand or model, so you cannot always substitute a similar in-stock item the way you might in general retail.

Seasonality and demand

Medical supply demand has real seasonal shape: cold and flu season drives spikes in masks, thermometers, and over-the-counter remedies, while wound care and mobility aids see steadier demand with mild upticks after holidays when falls and injuries are more common. Incontinence and daily living aids tend to be flat year-round but can see new-customer surges tied to insurance plan renewals in January. Plan safety stock higher going into autumn and January, and review slow movers like mobility aids twice a year rather than weekly, since over-ordering there locks up cash in bulky, low-turn items.

Suppliers, lead times and minimums

Suppliers in this space range from large medical distributors with next-day or short local lead times, to specialty manufacturers of mobility aids or diagnostic devices where overseas suppliers often take several weeks. Case packs are common and strict (gloves by the case, dressings by the box of a fixed count), and many distributors set a minimum order value or unit count before they will ship at all. Smaller specialty brands may also require you to reorder in full case packs with no mixing of sizes or colors within a pack.

Worked example

Say you sell nitrile exam gloves, size medium, and you average 8 boxes a day. Your supplier's lead time is 7 days and you keep 3 safety days, so your reorder point is 8 x (7 + 3) = 80 boxes. You want 14 days of cover, you currently have 60 boxes on hand and 0 on order, so order quantity = 8 x (7 + 14) - (60 + 0) = 168 - 60 = 108 boxes. If the supplier's case pack is 20 boxes, you round up to 120 boxes to hit the next full case.

Try it with your own numbers in the reorder point calculator, or size your buffer with the safety stock calculator.

A simple system to start this week

1. List every SKU with its supplier, lead time, and case pack size, including shelf-stable vs expiry-dated items separately.
2. Set safety days higher for items tied to clinics or insurance reorders, where a stockout means a lost contract, not just a missed sale.
3. Build reorder points using actual daily sales per variant, not gut feel, especially for gloves, masks, and other fast movers.
4. Track expiry dates manually or in a separate system, and rotate stock FIFO before SteadyShelf-driven reorders arrive.
5. Review slow-moving, high-cost items like mobility aids quarterly to avoid over-ordering into a low-turn category.
6. Confirm supplier minimums and case packs before approving any draft purchase order, since medical distributors enforce these strictly.

How SteadyShelf fits medical supply stores

SteadyShelf fits the repetitive, case-pack-heavy reordering work in medical supply stores: it forecasts daily sales per variant, tells you when to order from each supplier based on their lead time, and rounds quantities to case packs and minimums automatically. It does not track lot numbers or expiry dates, so you still need a separate process (spreadsheet or your receiving workflow) to rotate stock FIFO and flag items nearing expiry before they go into a purchase order.
