Table Structures and Column Definitions

Sheet 1: Weekly Overview (Annual View)

This is a chronological table spanning 52 weeks, with each week represented as a column. The first row lists the week number (Week 1 to Week 52), while the second row contains dates for the Monday of each week. Key inventory metrics are presented in rows below:

• Item Name (Text – String): Product or material name.
• Category (Text – String): e.g., Raw Materials, Packaging, Finished Goods.
• Last Week's Stock (Number – Integer): Opening stock level from the previous week.
• Week’s Sales/Usage (Number – Integer): Units consumed or sold during the week.
• Replenishment Ordered (Number – Integer): Quantity ordered for delivery before the next cycle.
• Expected Delivery Date (Date): Arrival date of replenished stock, based on supplier lead time.
• This Week’s Closing Stock (Number – Integer): Calculated using formula: Opening Stock + Replenishment – Usage.
• Status Indicator (Text – Conditional Status): “Normal”, “Low Stock Alert”, or “Stockout Risk”.

Sheet 2: Item Master List

This static reference table contains essential item metadata:

• Item ID (Text – Unique Code): Alphanumeric identifier.
• Description (Text – String): Full product description.
• Unit of Measure (Text – String): e.g., Units, Pounds, Liters.
• Reorder Point (Number – Integer): Minimum stock level triggering a reorder.
• Lead Time (Days) (Number – Integer): Time from order placement to delivery.
• Safety Stock Level (Number – Integer): Buffer stock to prevent shortages.

Sheet 3: Weekly Replenishment Tracker

A dynamic log that records ordering activities per week:

• Week # (Number – Integer).
• Date Ordered (Date).
• Item ID.
• Quantity Ordered.
• Status: Open, Shipped, Delivered, Canceled (Text – Dropdown).
• Expected Delivery Date (Auto-calculated): =Date Ordered + Lead Time.

Formulas Required

• Closing Stock Formula: In Weekly Overview, column for Closing Stock: =B4 + D4 - E4 (assuming B is opening stock, D is usage, E is replenishment).
• Status Indicator Logic: Using IF and COUNTIFS: =IF(F4 <= G2,"Low Stock Alert",IF(F4 = 0,"Stockout Risk","Normal")) — where F4 is closing stock, and G2 is reorder point (pulled from Item Master).
• Expected Delivery Date: On Replenishment Tracker: =Date_Ordered + Lead_Time, referencing lead time from the Item Master.
• Weekly Forecast: Use a rolling average formula to estimate demand based on last 4 weeks of usage: =AVERAGE(OFFSET(Usage_Column, -4, 0, 4)).

Conditional Formatting Rules

To enhance readability and highlight critical inventory conditions:

• Low Stock Alert: If Closing Stock ≤ Reorder Point → Highlight cell in orange.
• Stockout Risk: If Closing Stock = 0 → Highlight cell in red.
• Past Due Deliveries: On Replenishment Tracker, if Expected Delivery Date is earlier than today and Status ≠ Delivered → Highlight in dark red.
• Overstock Warning: If Closing Stock > 2× Safety Stock → Highlight in yellow.

User Instructions

1. Set Up the Master List: Fill out the Item Master List with all inventory items. Ensure each Item ID is unique and lead times are accurate.
2. Populate Weekly Overview: Begin by entering opening stock for Week 1 (from actual physical count), then enter usage data weekly as sales or consumption occur.
3. Generate Replenishment Orders: Based on forecasts and closing stock levels, use the Replenishment Tracker to place orders. The system will auto-calculate delivery dates.
4. Update Weekly: Each Monday, input updated usage and replenishment data. Review status alerts before finalizing.
5. Analyze Performance: Use the Inventory Performance Dashboard weekly to review KPIs and adjust reorder points or safety stock levels if needed.
