Formulas Required

The template uses a suite of Excel formulas to automate calculations and ensure real-time accuracy:

• Stock Balance = SUMIF(Stock Levels & Movements!$D:$D, [Product ID], Stock Levels & Movements!$G:$G): Calculates current stock level.
• Days to Reorder = (Reorder Level - Current Stock) / Daily Demand: Automatically calculated based on sales trends.
• Stock Turnover Ratio = COGS / Average Inventory: Tracks efficiency of inventory use.
• Forecasted Demand (Monthly) = AVERAGE(Previous 12 Months Sales) * (1 + Growth Rate): Based on historical data.
• Cost of Goods Sold = SUM(Selling Price * Quantity Sold): Calculated in Sales & Revenues sheet.
• Inventory Value = Sum(Stock Level × Cost Price): Critical for financial reporting.

Conditional Formatting

• Red Highlight (Low Stock): When stock level is below reorder level or less than 10% of max.
• Yellow Highlight (High Stock): When stock exceeds 90% of max level to alert overstock risk.
• Green Background (On-Time Delivery): In Purchase Orders when delivery date is met or early.
• Warning Borders: Applied to entries with negative quantity in transactions.
• Different Font Colors for Statuses: E.g., Red for “Pending,” Green for “Received” in PO sheets.
