Sheet Names and Their Purposes

• 1. Inventory Overview (Main Dashboard): A dynamic summary sheet showcasing key metrics such as current stock levels, low-stock alerts, monthly sales trends, and reorder recommendations.
• 2. Product Catalog: Centralized list of all products with unique identifiers, descriptions, unit costs, selling prices, supplier information, and safety stock levels.
• 3. Monthly Inventory Log: Detailed daily/weekly entries for purchases, sales, returns, adjustments (e.g., damage or theft), and ending balances for each product.
• 4. Reorder Tracker: A color-coded table that highlights which products need immediate reordering based on predefined thresholds and current stock levels.
• 5. Supplier Performance: Tracks delivery times, order accuracy, and responsiveness from each supplier to support better vendor decisions.

Table Structures and Column Definitions

The template uses structured tables (Excel Tables) for easy data management, filtering, and formula integration. Below is a breakdown of key tables:

1. Product Catalog Table

2. Monthly Inventory Log Table

Formulas Required for Automation

• =VLOOKUP(Product ID, ProductCatalog, 10, FALSE) – To pull current stock level from the Catalog.
• =IF([@Current Stock Level] < [@[Safety Stock Level]], "Reorder Now", "OK") – For alert generation in Reorder Tracker sheet.
• =SUMIFS(InventoryLog[Quantity], InventoryLog[Product ID], [@Product ID]) + [@[Initial Stock]] – To calculate running stock balance.
• =IFERROR(VLOOKUP([@Product ID], ProductCatalog, 8, FALSE), 0) – Safe lookup for cost and price values.

All formulas are designed to auto-update when new transactions are added, reducing manual errors and saving time.

Conditional Formatting Rules

• Low Stock Alert: Highlight cells in the “Current Stock Level” column red if less than safety stock (e.g., < 10).
• Reorder Recommended: Color code cells in the Reorder Tracker sheet yellow for items below threshold.
• Daily Changes: Apply gradient fill to the “Quantity” column based on transaction size (large positive/negative values highlighted).
