An inventory scanner, also known as a barcode scanner or a scan gun, is a handheld device used to scan and read barcodes on products. These devices are often used in warehouses, factories, and retail stores to track and monitor inventory levels.
We all know how important it is for manufacturers and retailers to keep accurate inventory records. Some problems associated with inventory management, such as overstocking or understocking, can lead to higher costs or lost sales.
For this reason, scan guns have become an indispensable component for businesses aiming to automate and streamline their inventory management process.
In this article, we’ll take a closer look at inventory scanners to understand how they work, why they are important and how to use them in your inventory management.
How does an inventory scanner work?
Nowadays, most products carry a barcode that contains information about the product itself. These barcodes consist of a series of bars, spaces and numbers that can be decoded using an inventory scanner.
Once the barcode has been scanned, the scan gun sends the data to an inventory management system on a computer or mobile device via Bluetooth or Wi-Fi. This makes it easier to track inventory levels.
What are the advantages to using an inventory scanner?
It is no surprise that retailers use barcode scanners to manage their inventory. In fact, there are several advantages to using an inventory scanner. These advantages include:
- Time-saving: it can help businesses save time and money by automating the inventory tracking process. By using a scan gun, employees can simply scan the barcode rather than count products manually.
- Accuracy: tracking inventory manually can be not only time-consuming, but also more prone to errors. Using barcode scanners can drastically reduce the risk of human error.
- Better inventory management: these devices can also help businesses avoid overstocking or understocking products. By tracking inventory more efficiently, businesses can anticipate some problems such as excessive inventory or lost sales.

3. How does the Sheetgo inventory management template work?
The inventory management template is an automated workflow that consists of 4 spreadsheet files and 3 forms. The first 3 spreadsheets are dedicated to different aspects of your inventory: items, check-in, and check-out. The items sheet is connected to both the check-in and check-out sheets.

All of these spreadsheets are connected to a master sheet, which is your inventory database. This master sheet helps sort your data and provides insights into your inventory through a visual dashboard.
Additionally, Sheetgo offers forms that simplify the inventory management process. There are three forms for each area of your inventory: item registration, check-in, and check-out. These forms include a barcode scanner system that can automate the entire item management process. Once you scan or input your items, Sheetgo automatically transfers the data into the corresponding spreadsheets for your use.
4. Using the Sheetgo forms to input your items
There are 3 Sheetgo forms that will help you input your data into the spreadsheets.
Register item: Input new items into your inventory using the register item form.
Check-in item: Input the items that have entered the inventory with the check-in item form.
Check-out item: This form is used to show which items have left the inventory.
When you fill out the forms, Sheetgo will automatically transfer the data to the corresponding spreadsheet and update the rest of the sheets accordingly.
In order to register an item, open the corresponding form and input the data into the fields.

Whenever you want to check in or check out an item, open the corresponding form and use your inventory scanner to read the barcode.
Bear in mind that you can also use a mobile phone, a tablet or a computer camera to scan the barcode. Once you submit your forms, Sheetgo will automatically transfer your data to the other spreadsheets.

5. Checking your master spreadsheet
You can track real-time inventory levels by opening the master spreadsheet at any time.

6. Schedule automatic updates
If you want to schedule automatic updates, click on the floating menu bar inside your workflow and select Automate.
Select how often you want automatic updates: hourly, daily, weekly, or monthly.
Sheetgo will automatically update the data in all spreadsheets.

7. Share the workflow with your team members
Your team members can have access to the forms and help you check in and check out the items.
