By combining forecasting models with inventory control mechanisms across multiple interconnected worksheets, users gain a holistic view of operational efficiency and future demand patterns.

Sheet Structure & Navigation

The template consists of seven distinct sheets, each serving a specialized function within the sales and inventory ecosystem:

1. Data Input (Raw): Central hub for importing daily sales, purchase orders, and inventory adjustments.
2. Inventory Dashboard: High-level overview of stock levels, reorder alerts, and warehouse utilization.
3. Sales Forecasting Engine: Advanced modeling engine using historical data to predict future sales volume.
4. Reorder Recommendations: Automated suggestions based on forecasted demand and safety stock thresholds.
5. Inventory History Log: Detailed audit trail of stock movements, including receipts, withdrawals, and adjustments.
6. Product Catalog: Master list containing product details such as SKU, category, supplier info, lead time, and unit cost.
7. Performance Analytics & Charts: Interactive dashboards with visualizations for sales trends and inventory turnover.

Table Structures & Data Types

Data Input (Raw) sheet contains a structured table named "tblSalesRaw", formatted as an Excel Table (Ctrl+T). Columns include:

• Date (Date/Time): Date of transaction.
• Product ID / SKU (Text): Unique identifier from the Product Catalog.
• Quantity Sold (Number, Decimal): Units sold on a given day.
• Sales Price (Currency): Unit sale price in local currency.
• Order Type (Text): "Retail", "Wholesale", "Internal Transfer", etc.

The "tblInventory" table on the Inventory Dashboard includes:

• SKU (Text)
• Description (Text)
• Current Stock (Number, Integer)
• Reorder Point (Number, Integer)
• Safety Stock (Number, Integer)
• Last Updated Date (Date/Time)

The "tblForecast" table on the Sales Forecasting Engine uses historical data to generate weekly and monthly predictions:

• Period (Text or Date): Weekly or Monthly period (e.g., "2024-W15", "March 2024").
• Actual Sales (Number, Decimal)
• Forecasted Sales (Number, Decimal)
• Error Margin (%) (Percentage): Deviation between actual and forecasted values.

Required Formulas & Functions

Dynamic formulas ensure automatic updates across sheets:

• =FORECAST.LINEAR(): Used in Sales Forecasting Engine to predict future sales using linear regression based on historical trends.
• =SUMIFS(): Aggregates total sales per SKU and date range from the raw data table.
• =VLOOKUP() or XLOOKUP(): Pulls product details (e.g., safety stock, lead time) from the Product Catalog sheet into other tables.
• =IF(AND(...), "Reorder Needed", "OK"): Conditional logic to flag products below reorder point after considering safety stock.
• =DATEDIF(): Calculates lead time between order placement and delivery for reorder recommendations.

Conditional Formatting Rules

To enhance visual clarity, the template uses conditional formatting:

• Red Background + Bold Text: For inventory items with stock ≤ reorder point.
• Yellow Highlight: Items where current stock is between 80% and 100% of safety stock.
• Green Fill: Stock levels above safety threshold (optimal).
• Red Error Margin (>15%): Highlights forecast inaccuracies in the Sales Forecasting Engine sheet.
