Supply Chain & Inventory Control: Reorder & Stocking Toolkit

Welcome — this interactive toolkit helps supply managers and clinical leaders translate usage data into practical reorder rules, par levels, and emergency protocols that reduce stockouts and expiry waste. Use the guided calculators for single-item decisions, save item-specific worksheets for sharing or later review, and complete the vendor scorecard and daily supply-board fields to improve visibility on the unit.

How to use: 1) Enter the item and basic demand/lead-time numbers into the calculator. 2) Follow the guided formulas and enter the computed results (help text explains each step). 3) Save the worksheet so your team can review or compare items. 4) Use the vendor scorecard template to record vendor performance and the daily supply-board fields to drive unit-level visibility.

Key formulas (for reference):

  • Demand during lead time = average daily usage × lead time (days)
  • Simple safety stock (approx.) = z × stddev_demand_during_lead_time (z depends on service level; e.g., z≈1.28 for 90%, 1.65 for 95%)
  • Reorder point = demand during lead time + safety stock
  • Par level = average daily usage × par period (days) + safety stock

If you need more advanced statistical methods (variable lead time, intermittent demand), treat this worksheet as a starting point and consult your analytics or quality team.

Descriptive name used on order forms and unit boards (e.g., 'Sterile Gloves - Size 7').
Where this worksheet applies (e.g., OR, SPD, ED, Ward 3).
Primary clinical or operational use for this stock
How the item is counted (each, box of 50, pack, tray).
Average units consumed per day over a representative period. If you track weekly/monthly averages, convert to daily.
Typical time from order placement to receipt. Use average lead time. If lead time varies, capture stddev in the next field.
If you have historic usage variability, enter it here. If unknown, leave blank and use a simple safety factor instead.
If lead time varies, provide its standard deviation to use a more accurate safety stock estimate.
Target probability of not stocking out during lead time. Higher service levels require more safety stock.
Suggested z: 1.28 for 90%, 1.65 for 95%, 2.05 for 98%. This field is a convenience; you may override if you prefer a different margin.
Formula: average daily usage × lead time (days). You can compute here and save the result.
Simplified method: safety stock = z × stddev_demand_during_lead_time. If you provided stddevs, estimate stddev_demand ≈ sqrt(lead_time_days) × stddev_daily_usage. If no stddev available, consider using an ad-hoc safety multiplier (e.g., 1–3 days of average usage).
Formula: reorder point = demand during lead time + safety stock. Enter the computed value to save the rule.
How many days of stock you want on hand between replenishments (e.g., 7 days for weekly restock).
Formula: par level = average daily usage × par period (days) + safety stock. Enter the computed par-level to help unit staff with stocking.
If on-hand inventory falls below this many days of average usage, follow the emergency reorder protocol below. Example: 1–2 days for critical OR items.
Yes/No. If no, use the guidance section in the introduction to draft a protocol (who to call, expedited shipping, alternative items).
Vendor or distributor used for this item.
Rate from 1 (poor) to 5 (excellent) based on received quality.
1.0 10.0
Rate from 1 to 5 for on-time performance.
1.0 10.0
Rate from 1 to 5 for customer service and issue resolution.
1.0 10.0
Notes used to discuss vendor performance or trigger procurement actions.
Use this field to paste or summarize what the unit should display on a daily supply board (on-hand, reorder point, par level, next expected delivery).
Select any known risks related to this item.
Person responsible for maintaining the par and reorder rule locally.
Record why values were chosen, dates of changes, approvals, or follow-up actions.
