Uniform Reorder Points: A Simple Buffer-Stock Method for Growing Teams
A uniform shortage begins before the shelf is empty. Hiring, replacement demand and supplier lead time consume the remaining stock while procurement still believes there is enough on hand. A reorder-point system turns that problem into a calculation.

Direct Answer
Set a trigger for each size: expected demand during supplier lead time plus safety stock. If M-size usage averages 6 pieces per week, replenishment takes 4 weeks and you want 2 weeks of safety stock, the trigger is (6 × 4) + (6 × 2) = 36 pieces.
Calculate demand by size
A company can hold 100 spare shirts and still be out of stock if the next hires need L and only XS remains. Track issues by size for several months. Separate new-hire issues, damaged-garment replacements and planned refreshes because their demand patterns differ. If history is limited, start with the current workforce size distribution and update it as real issues occur. Do not split inventory equally across sizes unless the workforce is actually distributed equally. The goal is a stock profile that predicts the next request, not a visually tidy shelf.
Use lead-time demand plus safety stock
The basic formula is reorder point = average usage during lead time + safety stock. If L usage is 4 pieces per week and lead time is 5 weeks, lead-time demand is 20 pieces. Add three weeks of protection, or 12 pieces, and the trigger becomes 32. Stable office teams may need a smaller buffer than retail openings or project crews. If demand is seasonal, use the expected seasonal rate rather than a yearly average. Reorder points should change when the business pattern changes.
Separate trigger from par level
The reorder point says when to buy; the par level says what stock level to restore. If M triggers at 36 pieces but the preferred full-stock position is 60, an order placed at 34 should normally restore toward 60. This reduces constant small orders and can consolidate decoration runs. Do not inflate par stock just to chase a lower unit price. Decorated uniforms can become obsolete when branding, garment models or staff sizing changes. Buying efficiency and obsolescence risk must be balanced.
Keep one ledger and one approved reference
HR, operations and procurement should not keep competing stock counts. Use one ledger for issues, returns, write-offs and incoming stock. Track blank garments separately from personalised garments because their reuse value differs. Store the approved style code, colour, decoration size and placement with the inventory record. A perfect reorder formula is useless if the replacement batch arrives in a different navy or with a shifted logo. Inventory control and specification control belong together.
| Planning area | What to verify |
|---|---|
| Calculate demand by size | Decision rule and operational check |
| Use lead-time demand plus safety stock | Failure mode and control |
| Separate trigger from par level | Decision rule and operational check |
| Keep one ledger and one approved reference | Failure mode and control |
Make the specification measurable, test it in the real operating environment, and keep the approved reference for the next reorder.
Frequently Asked Questions
Should we test before a full run?+
Yes. A production-size sample exposes fit, handling, adhesion or durability problems that are easy to miss on screen.
What should be kept for reorders?+
Keep the approved specification, artwork version, supplier reference and a physical control sample where practical.
Is the lowest unit price the best buying decision?+
Not necessarily. Include replacement risk, obsolete stock, reprint frequency and operational failure in the total cost.
