Q: Is the platfrom web based or an installed application?
A: The entire platform is web based and can be used from any computer or mobile device with a modern browser (Firefox, Chrome, Safari, IE10+). We recommend using Firefox because of it supports silent printing (bypassing print dialog boxes).

Q: Can I see how these tool work?
A: You can check out demos of the basic FBA box packing workflows via the Scangun input demo, the Bulk input demo or the multi-box pack shipments demo. The demo's provide a view into our most basic FBA functionality to see if it fits your workflow. The demo does not show reporting, shipment validation, VendorCentral or any of the other advanced features.

Q: Does this software connect to my Amazon account?
A: You have the option to connect your Amazon account to download shipment plans. That is not required. You can manually upload shipment plans into our platform, if you do not want to connect your account or have more than one account.

FBA Workflow and Functionality

Q: I sell on Amazon via FBA. What can 2D barcodes do for me?
A: All FBA sellers are required to provide box content information for each box to Amazon. If you do not provide box contents information, Amazon will apply a fees per box shipped. The fee varies for Amazon US and EU warehouse destinations. If you provide box content information, you will not be charged this fee. You can get more details about the Amazon box contents requirements in SellerCentral help: for Amazon US and Amazon EU.

Important: If you do not see using 2D barcodes as an option in SellerCentral, enable the 2D barcode option in Seller Central Inbound Settings page.

Q: Are the 2D barcodes compatible with Amazon US, Canada and Amazon EU warehouses?
A: We support all Amazon FBA warehouses globally that require box contents information. The 2D barcode that Amazon requires for box contents are universal for all FBA destinations.

Q: Can I use this tool to skip providing box contents for Amazon FBA in SellerCentral?
A: You can use this tool to avoid using the manual web form or uploading an Excel/CSV file into SellerCentral.

Q: Why use this tool to generate the 2D barcodes for Amazon FBA?
A: This tool provides multiple optimized workflows for creating the 2D barcodes, validating packed items to your shipment plans and other replenishment workflow optimizations.

If you use 2D barcodes, you do not need to provide box contents information through Seller Central. Apply a 2D barcode to each box as it's packed and then you can skip providing box contents in SellerCentral. Amazon FBA can simply scan the barcodes to determine the contents of a specific box.

The 2D barcode label method is particularly recommended for:

  • Sellers shipping inventory from third-party suppliers. Your supplier can provide box-level detail without coordinating with you regarding FBA shipment creation details. FBA shipping labels still need to be applied to boxes, but FBA shipping labels can be applied independently of the 2D barcode labels specifying the box’s contents. Alternatively, you can use our combined labels to generate a combined 2D box content and inbound FBA label together.
  • Sellers using the Marketplace Web Service to create shipments or who otherwise have high-volume operations. The benefit to 2D barcode labels is that the solution is easily scalable.
  • FBA prep centers. Simplest way to provide box contents information without additional files or customer account access.
NOTE: The 2D barcode is not a replacement for the FBA label and shipping label. The FBA label will still need to be present on each box of a shipment to properly process your inbound shipments. Our premium and enterprise plan does have the functionality to combine the FBA label alongside the box content label. Using this functionality, you only need to apply our label to the box.

Q: What about expiration date labels?
A: Products that expire must be prepped to ensure that the expiration date is accessible for Amazon associates during the receiving process. You are required to include the expiration date on the outside of the prepped product. Failure to include the expiration date may cause the items to be relabeled at your cost. Please review the Amazon instructions for handling items with expiration dates.

You can print FNSKU and expiration date labels and track expiring inventory at FBA as part of your box packing workflow.

Q: What if my entire shipment fits into one box?
A: Per Amazon, for shipments with only one box, you do not need to provide box level information unless the shipment contains expiration-dated products.

Q: We work on multiple shipments at one time. Can I pack multiple shipments at the same time or switch between shipments as I'm packing?
A: You can work on multiple shipments at the same time. You can either pack different shipments at different pack stations or you can pack a few items from Shipment A, switch to packing Shipment B and then when ready go back to finish Shipment A. Everything is stored and you can pick up where you left off.

Q: Can this tool be used for the same shipment on the multiple computers at the same time?
A: Yes. If you have a shipment consisting of multiple boxes, you could have multiple boxes being packed at the same time. HOWEVER, you cannot have multiple computers packing one box. For example, if you have a shipment of 10 boxes and 2 workstations, each workstation can pack a box at a time for the same shipment. If you have a 1 box and 2 workstations, this will not work.

Q: Can this tool keep track of the items I scan?
A: Yes. With the premium or enterprise plan, the platform keeps track of the items you pack. You are able to look up the item and box information by Shipment, FNSKU / UPC, and by expiration dates. The information is retained for at least year from creation date. This is the perfect way to reconcile the items you packed to Amazon shipment plan using our shipment validation functionality. You can upload the Amazon shipment plan to verify that the packed items match the plan.

Q: I ship LTL, what features are available to help me?
A: With the premium or enterprise plan, you can log the weight of each box and pallet IDs. The reporting will then track the weight of each pallet and which boxes are supposed to be on each pallet. Please remember, per Amazon instructions, the units on each pallet must all belong to one shipment and the total weight of the pallet must not exceed 1,500.00 lbs. You can also print Pallet labels directly from the app as your pallets are completed.

Q: How come the UI looks a little plain?
A: Our UI is optimized for high volume operations. It's not pretty because it's optimized for warehouse environments where speed and accuracy are the key factors.

VendorCentral Workflow and Functionality

Q: How can I generate SSCC Carton labels for my VendorCentral shipments?
A: We allow a simple way to generate SSCC labels for all your cartons by uploading a CSV file with shipment information. For each carton in the CSV file, we will generate the 4x6 formated labels for you to print. The CSV file template is available here.

Q: How can I generate 2D BPS Carton labels for my VendorCentral shipments?
A: We allow a simple way to generate BPS labels for all your cartons by uploading a CSV file with shipment information. For each carton in the CSV file, we will generate the 4x6 formated labels for you to print. The CSV file template is available here.


Q: What label sizes are supported for the FBA and VendorCentral labels?
A: The generated FBA and VendorCentral labels are designed to fit a 4x6 label that are used with thermal (label) printers. If you're using a regular printer, it will neatly print in the left top corner of a regular sized page.

Q: Can you recommend a label printer that works well with this?
A: The following printers are known to work well for printing the 4x6 labels:

  • Dymo 4XL
  • Zebra LP2844
  • Zebra GC420
  • Zebra GK420, GK420d
  • Zebra ZE450
  • Brother HL-2275DW

However, the platform should work with any label printer that supports a 4x6 label. This is just a list gathered from happy customers. The Dymo 450 will NOT work as the labels are too small.

Q: What label sizes are supported for expiration date and FNSKU item labels?
A: Today, we support 2.00in x 1.00in, 2.5in x 1.00in, 2.61in x 1.00in and 3.00in x 1.00in labels among many others. If you find yourself using a different label size and want to use the tools, please contact us and we'll work with you to get the settings right to use your preferred labels.

Q: Can I setup silent printing of the labels, without the Print Dialog box?
A: You can setup silent printing in Firefox. Follow the silent printing instructions to learn more.

Mobile Devices

Q: Does this work on tablets/phones?
A: Yes. However, there are two main topics that come up with mobile devices: barcode scanning and printing. Try using the demo functionality to verify that it works in your environment.

  • Printing. Since the tool uses the built-in browser on your device, if you set up your mobile device to print to a printer in your environment, you should be able to print the 2d barcode without any problems.
  • Barcode Scanning. Because this tool is web-based (runs in a browser) and not a native app it does not have access to the phone's camera for barcode scanning. We recommend using a Bluethooth scanner paired with your mobile device for the barcode scanning. This will let you scan barcodes much faster than with the device's camera, and works with our tools.

Q: Can you recommend a barcode scanner?
A: Any barcode scanner that works with your device / computer will work with the app. We use a basic USB scanner to test the platform and it seems great. For tablets and phones, a Bluetooth or any other wireless scanner would work much the same way. The computer sees all scanners as just a keyboard, so there is no difference in wireless or wired. If you want something for the long run, the recommended brands are Symbol/Motorola or Zebra because they are built to withstand a good amount of abuse.


Q: How much does this service cost?
A: There are tiered pricing plans, which are outlined here. You can try all of the packing and barcode generating functionality by using the demo. Once you sign up, there is a 1 day grace period before your credit card is charged.

Q: Can I use multiple workstations or is that an extra fee?
A: There are no extra fees if you want to use 1-2 workstations at the same time. If you're running a warehouse with over 3 packing workstations at the same time, you need to be on the premium or enterprise plan.

Q: Are there any additional costs?
A: No. You only pay the monthly subscription fee for the chosen plan.


Q: Is my data safe?
A: All billing is done securely via Stripe. We never store (or even see) your credit card information.

Q: Do you use or collect any of the information I provide?
A: Only if you ask. If you want to keep a history of packages and contents, signup for the premium or enterprise plan. In this case, the information will be stored, but that data will be accessible only to you. It will not be shared with anyone. If you do not use the premium plan, then no information about your shipments will be stored.

Q: Are there any limits on the monthly plan?
A: Yes. To prevent abuse and account sharing, the plans are limited by amount of shipments per month. Additionally, if you have more than 3 workstations used for packing at the same time, please select the enterprise plan.
