Streamline Inventory Management: Using Excel for Small Businesses

How to Use Excel for Inventory Management

An Excel inventory management system is essentially a spreadsheet that lists each product and its key details. This data usually includes product name, stock keeping unit (SKU), supplier, costs, retail prices, and quantity in stock. Maintaining this data gives you a real-time snapshot of your business’s inventory position.

Start by opening Excel and creating a new workbook. Your first sheet will become your main inventory database. Each row represents a unique product, and each column represents a type of information—such as price, supplier, or quantity—that helps you track and manage your products efficiently. As you work with the spreadsheet, you’ll determine which columns you want to include.

Essential Columns to Include:

• Unique Identifier: A product ID or SKU unique to each item.
• Product Name: The item’s name.
• Description: Size, color, model, and other characteristics.
• Supplier Information: The vendor or supplier name.
• Unit Price: The cost your business pays per item.
• Retail Price: The price customers pay.
• Quantity in Stock: Current number of units available.
• Inventory Value: Total value of the stock (Unit price x Quantity in stock).
• Reorder Level: Minimum stock quantity that triggers a reorder.

After building this framework, populate it carefully with your product data. As you make sales or receive new stock, regularly update this sheet to keep it accurate. Your inventory system works only if you maintain it consistently—reliable data entry prevents overselling items or missing reorder deadlines.

Excel Template for Inventory Management

To get started, use an effective inventory management template. This template includes an inventory list sheet, a sales orders sheet, and a purchase orders sheet. Keeping sales orders and purchase orders separate creates a clear audit trail and lets you use formulas that automatically update the main inventory list. This setup helps you manage inventory more accurately and minimize errors from manual data entry.

Inventory List: This is a detailed, itemized record of all the goods your business has in stock. It forms the foundation of your Excel inventory management system by providing an accurate picture of your current inventory.

Sales Orders Sheet: Whenever you sell a product, log it in the Sales Orders sheet. This record ensures that inventory levels decrease automatically when linked formulas are in place.

Purchase Orders Sheet: When you receive new stock, record it in the Purchase Orders sheet. Similar to the Sales Orders sheet, it helps you track stock increases and provides a record of purchases for reconciliation.

Excel Inventory Management Best Practices

Although Excel is a useful tool, maintaining an accurate and reliable inventory system depends on consistent updates and careful verification. Here are five practices to keep your spreadsheet accurate and actionable:

1. Establish a Unique Identifier for Each Item: Every product variation—size, color, model, etc.—needs a unique SKU or product ID.
2. Audit Your Physical Inventory Regularly: Schedule regular physical inventory counts and compare the numbers to the data in your Excel inventory template.
3. Use Data Validation to Minimize Errors: Excel’s data validation feature prevents mistakes by creating drop-down menus for columns like “Category” or “Supplier.”
4. Set Up a Dashboard with Key Metrics: Create charts and tables that show your most important key metrics, such as total inventory value, top-selling products, and items low in stock.
5. Back Up Your Excel File: Create backups often and store copies in a secure cloud service or external drive.

Useful Formulas and Features for Excel Inventory Management

Excel formulas can automate calculations, save time, and reduce the risk of manual errors, while built-in features like PivotTables help analyze your data visually. Some key formulas include:

• SUMIF: Automates stock level updates by summing values that meet specific conditions.
• VLOOKUP: Pulls accurate product information automatically from your main inventory list into other sheets.
• IF Statement: Automatically alerts you when an item reaches its reorder point.
• SUMPRODUCT: Calculates the total inventory value by multiplying each item’s quantity by its unit price.
• PivotTable: Summarizes, groups, and analyzes large amounts of inventory or sales data.

Alternatives to Excel Inventory Management

Excel is a great starting point for small business owners—it’s inexpensive, flexible, and familiar. But as your business grows, Excel spreadsheets can become difficult to maintain. The need for manual data entry increases the risk of human error, and managing hundreds (or thousands) of products across multiple sales channels can quickly get unwieldy.

Dedicated inventory management software provides a centralized system to automatically track stock levels, manage sales, and process orders in real time. Platforms like Shopify’s built-in inventory management tools sync data across your online and in-person sales channels, offering features such as:

• Real-time stock level updates across various sales channels
• Detailed reports and analytics on sales and inventory performance
• Automatic purchase order generation when stock is low
• Barcode scanner integration for faster and more accurate receiving and order fulfillment
• Multiuser access with defined permissions, eliminating version control problems
