Sheet Names

• Product Inventory: Main data sheet for all products.
• Cost Summary: Aggregates total costs, average prices, and cost trends over time.

Table Structures & Data Organization

The core table in the Product Inventory sheet is structured with a clean, user-friendly format. Each row represents a unique product, and columns capture all relevant information related to cost control and inventory.

Columns and Data Types:

• Product ID (Text): A unique identifier for each item (e.g., "P001"). Mandatory for tracking.
• Product Name (Text): Full name of the product.
• Description (Text): Optional field for detailed product notes.
• Category (Text): Grouping such as "Electronics", "Kitchen", or "Office Supplies". Helps in filtering and analysis.
• Purchase Price (Currency): Cost to acquire the product. Used to calculate cost per unit and profit margins.
• Sale Price (Currency): Selling price. If not available, leave blank or use "N/A".
• Quantity on Hand (Number): Current stock level. Must be non-negative.
• Last Restock Date (Date): When the last purchase was made. Helps in tracking inventory turnover.
• Reorder Point (Number): Minimum quantity to reorder (e.g., 5 units). Automatically flagged if below this threshold.
• Cost Per Unit (Calculated - Currency): Auto-calculated as =Purchase Price / Quantity on Hand.
• Total Value (Calculated - Currency): Auto-calculated as =Quantity on Hand * Purchase Price.
• Last Update (Date/Time): Timestamp of when data was last edited.

Formulas Required

The template uses only basic Excel functions to ensure accessibility and stability:

• =IF(Quantity on Hand < Reorder Point, "REORDER", ""): Flags items needing restocking.
• =COST PER UNIT = Purchase Price / Quantity on Hand (dynamic formula)
• =TOTAL VALUE = Quantity on Hand * Purchase Price (automatically updates when quantities change)
• =SUMIFS(Cost Summary, Category, "Kitchen"): Used in the Cost Summary sheet to filter by category.
• =AVERAGEIF(): Calculates average cost per product within a category.
• DATE() & NOW(): For timestamping last updates and restock dates.

Conditional Formatting Rules

To enhance visibility and decision-making, conditional formatting is applied in key cells:

• High-Cost Alert (Green/Red Highlight): If Total Value > 100%, highlight in red with "HIGH COST" message.
• Low Stock Warning: If Quantity on Hand < Reorder Point, the row turns yellow with a bold border.
• Overstock Indicator (Purple): If Quantity on Hand > 10x of Reorder Point, shows a purple background.
• Cost Efficiency: Cells where Purchase Price / Sale Price < 0.6 are highlighted in blue to indicate poor margins.
