Table Structures & Data Types

The template is built around relational data structures to ensure consistency, scalability, and ease of analysis. Each sheet uses a normalized table format to avoid redundancy and improve data integrity.

1. Product Master

Data types are strictly defined: Product ID as primary key (text, unique), prices as currency (number), status as text with a defined set of values. All fields are validated using data validation rules.

2. Monthly Inventory Log

This sheet logs all inventory events on a monthly basis. The "Type" field is a dropdown with predefined options to ensure data consistency. Quantity is stored as integer (number).

3. Sales Summary (Monthly)

Formulas Required

The template utilizes a robust set of Excel formulas to automate key metrics:

• SUMIFS() and VLOOKUP(): To calculate monthly sales and pull product prices from the master table.
• IF() with AND(): To determine reorder status based on stock level thresholds.
• CONCATENATE() or TEXTJOIN(): To generate SKU labels and formatted dates.
• MEDIAN(): For identifying average selling prices across product categories.
• DATEVALUE() & EOMONTH(): To calculate month-end totals and compare with previous months.

Conditional Formatting Rules

To enhance user experience and highlight critical data, the following conditional formatting rules are applied:

• Red fill for stock below 10 units – alerts low inventory in Monthly Inventory Log.
• Green background for products with sales growth >10% – indicates high performance.
• Purple highlight for negative profit margin (cost > selling price) – identifies losses.
• Dashed borders on rows where reorder alerts are active – draws attention to urgent restocking needs.
