Step 1: Download Your Barcode Scanning App
It’s never been easier to barcode scan with your phone in the warehouse! Start by downloading CartonCloud’s mobile app for iOS or Android and then connect your device to a handheld Bluetooth scanner. It’s that simple.
Step 2: Create Your Barcode Labels
You can’t scan what isn’t labeled! Before you start scanning, make sure every stock item, storage location, and pallet has a clear, scannable barcode label.
At Rockstar 3PL, barcode labeling is the key to accurate put-away and inventory management from the moment stock arrives in the warehouse.
“Stock comes in and we create a purchase order for an item. We print a label — a scannable label that has all the information that we just input on the initial purchase order and [then] we allocate those to locations.
We use a handheld scanner to scan the barcode on the pallet and whoever's putting it away just goes to the location and marries it to that location.” — Jimmy Skodras, Vice President of Operations and Logistics, Rockstar 3PL
By having clear barcode labels in place, your team can confidently scan and assign items to the right location, right from the start!
“We have the locations that are already on our racks, so if there was any question of what item is in that specific location — it’s as easy as scanning that barcode, and it pops up on your CartonCloud app.” — Jimmy Skodras, Vice President of Operations and Logistics, Rockstar 3PL
Once you have each label created, it’s time to get them printed. In CartonCloud, you can print warehouse labels on the move — simply export as a PDF, or directly print to a label printer via CartonCloud Connect.
Step 3: Start Scanning
Now you’re ready to put your barcode scanning app to work! Here’s how you can use CartonCloud’s WMS app while on the warehouse floor:
- Check in new stock on arrival — Simply scan barcodes as freight comes in, logging details instantly in your WMS.
- Pick and pack with confidence — Scan each item as you pick, ensuring every order is spot-on before it heads out the door.
- Move and update stock locations on the go — Scan as you move inventory between bins, aisles, or pallets, while keeping your system up-to-date in real time.
- Stay on top of inventory control — Need to know what’s in a location? Scan the barcode and instantly view or update inventory records in your app.
- Make put-away a no-brainer — Assign products to storage locations on the spot by scanning a stocks location.
- Track every movement, big or small — Scan as you go, whether you’re replenishing shelves or transferring pallets, so every move is logged and nothing gets missed.
Pro Tip: Mobile barcode scanning is especially useful in e-commerce operations, where order accuracy and fulfillment speed are paramount. In picking workflows like Pick to Tote, barcode scanning allows your team to pick multiple orders at once — while confirming accuracy at every step.

Using the CartonCloud mobile app, a smartphone, and a tote trolley, your team can move efficiently through the warehouse, scanning at key intervals to ensure every item is packed into the right order:
- First, scan the item location to pull up the products required for the order.
- Then scan the item barcode to pick the correct SKU.
- Lastly, scan the tote barcode assigned to the order so the correct items are packed together.
Each scan verifies the process along the way, so there’s no need to backtrack — speeding up fulfillment and helping you get more e-commerce orders out the door, faster.
