If you are doing Retail Arbitrage or Online Arbitrage on Amazon, you will inevitably hit a breaking point where managing shipments in Amazon’s clunky Seller Central interface becomes a nightmare. This is exactly where InventoryLab steps in.
In this comprehensive 2026 review, we analyze whether InventoryLab is still the gold standard for FBA accounting, prep, and shipping, or if you can survive without it.
Key Takeaways
- Scoutify 2 is Incredible: The included mobile sourcing app is arguably the best retail arbitrage scanning tool on the market.
- Streamlined Shipping: It drastically reduces the time it takes to prep, label, and box shipments for FBA warehouses.
- Profit Tracking: It calculates your true ROI by factoring in the exact buy cost, Amazon fees, and inbound shipping costs.
Why Arbitrage Sellers Need InventoryLab
When you are scanning items at Target or Walmart, you need to know exactly how much profit you will make after Amazon takes their FBA fulfillment fee, referral fee, and storage fee.
InventoryLab solves this with Scoutify 2 (included in your subscription). When you scan a barcode with your phone, it instantly pulls up the Amazon listing, shows you your precise profit margin based on your buy cost, and checks if you are actually restricted from selling that brand.
The Desktop Application (Stratify)
Once you buy the inventory, you have to ship it to Amazon. Creating shipments in Seller Central is notoriously tedious. InventoryLab’s desktop app (Stratify) allows you to list the item, print the FNSKU barcode label instantly via a Dymo/Zebra printer, and assign it to a shipping box in one seamless workflow. What used to take 3 hours in Seller Central takes 30 minutes in InventoryLab.

Start InventoryLab TrialFAQs
Does InventoryLab track my overall business profit?
Yes! Unlike Amazon's reports which only show revenue, InventoryLab tracks your COGS (Cost of Goods Sold), inbound shipping, and subscription fees to show you a true P&L statement.
Do I need InventoryLab for Private Label?
No. Private label sellers usually ship massive pallets directly from China to Amazon. InventoryLab is specifically designed for arbitrage sellers who are boxing up dozens of different individual SKUs in their garage.
Is Scoutify 2 better than the Amazon Seller app?
Yes. The free Amazon app doesn't factor in your specific inbound shipping costs or prep costs, meaning its profit estimates are often highly inaccurate. Scoutify 2 is much more precise.
Conclusion
If you are sending more than 100 arbitrage items to Amazon FBA every month, InventoryLab is not a luxury; it is a necessity. The time you save on shipment creation alone pays for the software, and the accounting accuracy ensures you actually know if your business is profitable.
