Table Structures & Column Definitions

1. Inventory List Sheet

This is the central table that defines all products in stock. The structure supports scalability and ease of updates.

2. Transactions Sheet

This sheet logs every inventory movement with timestamps and user inputs, enabling auditability and tracking of changes.

Data Types & Formulas Required

• Auto-Numbering (Product ID, Transaction ID): Use =CONCATENATE("INV-", ROW()) or similar to generate unique IDs.
• Stock Update Formula: In the Inventory List sheet, use: =SUMIFS(Transactions!$E$2:$E$100, Transactions!$C$2:$C$100, B2, Transactions!$D$2:$D$100, "Purchase") - SUMIFS(Transactions!$E$2:$E$100, Transactions!$C$2:$C$100, B2, Transactions!$D$2:$D$100, "Sale") This dynamically updates current stock based on transactions.
• Profit Margin Calculation: =IF(Cost Price <> 0, (Selling Price - Cost Price) / Cost Price, 0) – Displays margin percentage.
• Reorder Alert Formula: =IF(Current Stock Quantity <= Reorder Level, "LOW STOCK", "") – Triggers warning if below threshold.
• Total Value of Inventory: =SUM(Stock Quantity * Selling Price) – For quick valuation.

Conditional Formatting Rules

• Low Stock Highlighting: Apply red fill to cells where "Current Stock Quantity ≤ Reorder Level" using conditional formatting based on the formula above.
• Expiry Date Reminder: For products with expiry dates, highlight in yellow if within 30 days.
• Sales Trends: Use green fill for product categories with >10% growth over last month in sales data.
