Table Structures and Data Types

1. Inventory Master (Sheet: Inventory Master)

This is the central inventory repository. Each row represents a unique product or item.

• Item ID (Text/Number): Unique identifier, e.g., PROD001.
• Item Name (Text): Descriptive name like "Handmade Ceramic Mug".
• Description (Text): Additional details such as size, color, or material.
• Category (Dropdown List): E.g., "Ceramics", "Jewelry", "Supplies" – helps in filtering and grouping.
• Current Quantity (Number): Real-time stock count. Automatically updated from the Transactions sheet.
• Reorder Level (Number): Minimum quantity threshold triggering a restock alert.
• Unit Cost (Currency): Cost price per unit in your local currency.
• Selling Price (Currency): Retail price per unit.
• Supplier Name (Text): Name of the supplier or vendor.
• Last Restock Date (Date): Date when the item was last replenished.

2. Client Directory (Sheet: Client Directory)

Each row records a unique client, ideal for personal use where relationships matter.

• Client ID (Text/Number): e.g., CLI001.
• Full Name (Text): First and last name of the client.
• Email (Text, Validation): Email address with built-in validation to prevent errors.
• Phone Number (Text): Optional contact number.
• Preferred Contact Method (Dropdown): "Email", "Phone", "Message".

• Total Spent (Currency): Cumulative amount spent by the client (automated via formula).
• Last Interaction Date (Date): Most recent contact or transaction date.

3. Sales & Transactions (Sheet: Sales & Transactions)

Records every sale, delivery, or service rendered to a client.

• Transaction ID (Text/Number): e.g., SALE2024-045.
• Date (Date): When the transaction occurred.
• Client ID (Linked to Client Directory): Uses data validation to pull only existing clients.
• Item ID (Linked to Inventory Master): Ensures consistency in stock tracking.
• Quantity Sold (Number): How many units were sold.
• Selling Price per Unit (Currency): Auto-filled from the Inventory Master.
• Total Amount (Currency): Formula = Quantity × Selling Price.
• Payment Status (Dropdown): "Paid", "Pending", "Overdue".

Formulas and Automation

To enhance accuracy and reduce manual effort, the template includes powerful formulas:

• Inventory Update in Inventory Master: Uses =SUMIF(Sales!$C$2:$C$1000, A2, Sales!$E$2:$E$1000) to calculate total sold items per product and subtracts from the current stock.
• Total Spent by Client: In the Client Directory: =SUMIF(Sales!$C$2:$C$100, A2, Sales!$F$2:$F$100) where A2 is the client ID.
• Reorder Alert Indicator: Conditional formatting triggers when Current Quantity ≤ Reorder Level (using formula in a helper column).
• Aging Payment Tracker: Calculates days since due date for pending payments.

Conditional Formatting

To improve readability and highlight critical data, the template uses:

• Low Stock Alerts: Red background for items where current quantity is below reorder level.
• Pending Payments: Orange fill for transactions with "Pending" status.
• Frequent Clients: Green highlight (e.g., clients with 5+ transactions in the last 6 months).

User Instructions
