Why Use Google Sheets Instead of Expensive Inventory Software?

Many businesses assume that a robust inventory system requires costly software like SAP, NetSuite, or Fishbowl. However, as a 3PL provider specializing in logistics efficiency, we’ve helped companies cut costs by switching to Google Sheets-based inventory tracking.

Google Sheets provides significant cost savings. It is free, eliminating monthly software fees that can cost thousands annually. It also supports real-time collaboration. Multiple users can edit and update inventory simultaneously, making it perfect for remote teams and warehouse operations.

Customization is another key advantage. Unlike rigid inventory software, Google Sheets allows businesses to tailor columns, categories, and automation to their needs. It integrates seamlessly with Google Forms, barcode scanners, and Google Apps Script to automate data entry.

Scalability is another reason to use Google Sheets. While Excel is limited to local files, Google Sheets stores data in the cloud, making it ideal for businesses with multiple warehouses and locations. For companies handling FTZ fulfillment, eCommerce logistics, or retail distribution, an inventory management system in Google Sheets is often the smartest, most cost-effective choice.

Step 1: Creating Your Inventory Spreadsheet in Google Sheets

To build a functional inventory management system in Google Sheets, you need to organize data efficiently. Start by creating a new spreadsheet and setting up the first row for column headers.

Each column represents an essential part of your inventory. You should have an Item Name column to identify each product. The Item SKU column ensures that every product has a unique identifier.

A Description column provides brief details about the product. The Quantity in Stock column tracks available units in real time. A Reorder Level column helps identify when restocking is necessary.

Include a Supplier column to track vendor details. Add a Last Ordered Date column to monitor purchase cycles. Finally, a Stock Location column ensures the team knows where each item is stored.

Once these columns are set, populate the spreadsheet with your current inventory data. This will act as your real-time stock tracking system.

Step 2: Automating Calculations with Google Sheets Formulas

One of the biggest advantages of Google Sheets is the ability to automate inventory calculations. You can use formulas to track stock levels, reorder alerts, and overall inventory health.

A SUMIF formula allows you to automatically add incoming and outgoing stock levels. This helps maintain an up-to-date count of each product. A COUNTIF function tracks how often an item is sold, which is useful for sales analysis.

You can use a VLOOKUP function to quickly pull product details based on SKU. This eliminates the need for manual searches. An IF Statement formula can create automatic reorder alerts when stock is low.

By leveraging these formulas, Google Sheets will automatically update inventory levels and alert you when stock needs replenishment. This reduces manual errors and increases efficiency. Read more.

Step 3: Automating Data Entry with Google Forms

A common challenge with manual inventory tracking is data entry errors. At Tri-Link FTZ, we recommend integrating Google Forms to streamline updates.

Google Forms allows warehouse staff to update inventory without directly editing the spreadsheet. You can create a Google Form to log new stock arrivals and product sales. When staff submits a form, the data automatically updates in Google Sheets.

To improve accuracy, use drop-down menus in the form. This prevents typos and ensures accurate SKU entries. Notifications can be enabled to alert warehouse teams when stock changes.

Approval workflows ensure that all inventory adjustments are verified before updates go live. By automating data entry, businesses can reduce errors, improve efficiency, and save time.

Step 4: Enhancing Efficiency with Barcode Scanning

Barcode scanning can dramatically improve inventory accuracy. You can integrate a barcode system with Google Sheets in a few simple steps.

First, generate barcodes using an online barcode generator. Attach barcode labels to each product. Using a mobile barcode scanner, link scanned data directly to your Google Sheets inventory.

Setting up Google Apps Script allows stock levels to update automatically when scanned. This reduces human error and eliminates the need for manual data entry. Warehouse staff can simply scan a barcode, and Google Sheets will instantly update stock counts.

For high-volume logistics operations, integrating barcode scanning with an inventory management system in Google Sheets helps eliminate stock discrepancies. This ensures inventory data remains accurate and up to date.

Step 5: Linking Multiple Sheets for a Scalable Inventory System

As a 3PL provider handling large-scale fulfillment, we often set up multi-sheet inventory systems for businesses. Managing inventory across multiple locations requires an organized approach.

A Main Inventory Sheet should track stock levels, reorder status, and supplier information. A separate Sales Sheetshould log all outgoing products. A Purchases Sheet should record incoming inventory.

Additionally, an Order History Sheet should archive past sales and restocks. This allows businesses to track trends and manage supply chains effectively. Using IMPORTRANGE and QUERY formulas, businesses can pull data from multiple sheets, creating a centralized dashboard.

By structuring Google Sheets this way, businesses can manage large inventories efficiently. This setup makes it easier to track stock movements across different warehouse locations.
