Step 3: Set Reorder Points

Inventory Management Example

Here is an example of inventory optimization for a product line:

Stockout Risk

Product A

Current: 15 units

Daily Sales: 8 units

Days Left: 2 days

Action: Reorder NOW

Overstock Warning

Product B

Current: 250 units

Daily Sales: 3 units

Days Left: 83 days

Action: Reduce Order

Optimal Level

Product C

Current: 85 units

Daily Sales: 5 units

Days Left: 17 days

Action: Maintain

💡 Key Insight

Product A needs immediate reorder to avoid stockout. Product B is overstocked — reduce next order by 50%. Product C is at optimal levels.

Tips for Better Inventory Control

💡 Calculate Your Reorder Point

Reorder Point = (Daily Sales × Lead Time) + Safety Stock. This ensures you reorder before running out.

💡 Monitor Sell-Through Rate

Aim for a sell-through rate of 30-40% per month. Lower rates indicate overstock; higher rates risk stockouts.

💡 Use ABC Analysis

Classify products by value: A-items (top 20% revenue), B-items (next 30%), C-items (bottom 50%). Focus management effort on A-items.

💡 Plan for Seasonality

Build inventory 60-90 days before peak seasons. Use historical data to predict seasonal demand spikes.

💡 Regular Inventory Audits

Conduct monthly inventory audits to reconcile physical counts with system records and identify discrepancies early.
