A discounted purchase does not automatically improve a medical distributor’s profitability. If products remain in storage for months, capital is tied up while fast-moving items may be out of stock. Effective purchasing balances unit price, demand, lead time, inventory turnover and available working capital.
Understand inventory turnover
Inventory turnover describes how often inventory is sold and replenished over a period. A common financial measure is cost of goods sold divided by average inventory value for the same period. For operational planning, also examine units sold and days of stock on hand by SKU.
Review the last three months by product and customer
Group sales by product, packaging format, customer segment and order frequency. Flag unusual tender deliveries, one-off bulk purchases and seasonal changes so they do not distort the forecast. The objective is to identify recurring demand rather than simply repeat the previous purchase quantity.
Calculate reorder points
A basic reorder point combines expected demand during replenishment lead time with a safety-stock allowance. If average daily demand is 20 units and lead time is 10 days, expected lead-time demand is 200 units before any safety stock. Adjust the buffer for variability and service requirements; this example is illustrative, not a universal rule.
Validate demand before introducing a new SKU
Discuss the proposed item with existing customers and, where feasible, collect purchase intentions or pre-orders. A product that looks attractive in a catalogue may not match the sizes, materials or packaging actually used by the market.
Negotiate the right assortment with manufacturers
Discuss minimum order quantities, carton configurations, delivery intervals, product specifications and whether staged deliveries are possible. A larger order may reduce unit cost but increase holding costs and obsolescence exposure.
Monitor a small set of purchasing KPIs
Track stockout frequency, inventory days, aged stock, forecast error, order fulfillment and working capital committed to slow-moving lines. Review exceptions frequently rather than relying on a single monthly total.
Worked example: inventory turnover and replenishment
Consider a distributor with annual cost of goods sold of TRY 2,400,000 and average inventory at cost of TRY 400,000. Annual inventory turnover is 2,400,000 ÷ 400,000 = 6 turns. Approximate days in inventory are 365 ÷ 6 = 60.8 days. These are illustrative figures; calculate the numerator and denominator using the same valuation basis and reporting period.
For one examination table cover SKU, suppose demand averages 20 rolls per working day, supplier lead time is ten working days and the chosen safety stock is 80 rolls. The reorder point is (20 × 10) + 80 = 280 rolls. Place or release a replenishment order when the inventory position—on-hand stock plus confirmed inbound stock minus allocated demand—reaches the reorder threshold. Do not rely on physical stock alone when large customer orders are already committed.
Operational KPI dashboard
| KPI | How to calculate | Why it matters |
|---|---|---|
| Inventory turnover | Cost of goods sold ÷ average inventory at cost | Capital efficiency |
| Days of stock | 365 ÷ annual turnover | Stockholding exposure |
| Reorder point | Lead-time demand + safety stock | Replenishment trigger |
| Stockout rate | Unfulfilled requested order lines ÷ total requested lines | Service continuity |
| On-time in-full | Orders delivered complete and on time ÷ orders due | Supplier performance |
Review demand at SKU level
Segment products by dimensions, packaging, material construction and customer application. For example, examination table covers of different roll lengths should not be combined into one forecast when customers purchase them for distinct workflows. Remove exceptional tender shipments from the baseline or model them separately. Compare three-month demand with the prior year where seasonal information exists.
Purchase-order planning checklist
- Confirm product dimensions, carton quantity and technical specification.
- Validate available stock, open customer commitments and confirmed inbound orders.
- Calculate average and variable demand over the real supplier lead time.
- Agree minimum order quantity, production capacity, lead time and staged deliveries.
- Review transport, storage, payment terms and the cost of slow-moving stock.
- Reassess the plan after major customer wins, tender deliveries or demand changes.

Frequently asked questions
What should be measured first?
Start with a clearly defined baseline, a consistent reporting period and an outcome directly connected to the purchasing or commercial decision.
Does one metric tell the full story?
No. Combine quantitative results with technical suitability, operational constraints and feedback from the people using the products.
