Inventory Lab Review 2026 — FBA Accounting + Scanner Worth $39/Month?
Inventory Lab bundles FBA accounting with the Scoutify scanner. Here's what each component actually delivers, how it compares to SellerAmp, and when the $39/month justifies itself.
What Is Inventory Lab?
Inventory Lab is an Amazon FBA seller management platform that handles three things: profit and loss accounting (tracking what you actually made after all fees and COGS), FBA listing and prep workflow (creating shipments faster than Seller Central), and mobile sourcing via its Scoutify scanner app.
It launched in 2012 and remains one of the most-used FBA accounting tools among mid-level sellers. The $39/month fee covers all three components — making it a genuine bundle rather than a standalone accounting tool at a premium price.
What You Get: 3 Components
Connects to your Amazon account and pulls all sales, fees, refunds, and reimbursements automatically. You enter your cost of goods per unit and Inventory Lab calculates your actual net profit — not Amazon's estimated numbers, which exclude COGS and other costs. Essential for understanding whether you're actually profitable.
Creates FBA shipments faster than Seller Central's native interface. Track your buy costs at listing time, print labels, and create shipment plans in a streamlined interface. Products bought with BNPL can have their installment costs entered as COGS for accurate P&L.
iOS and Android barcode scanner. Shows ROI calculation, Keepa chart, BSR, and gating status per scan. Buys logged in Scoutify automatically populate in your Inventory Lab account with cost entered at scan time.

Inventory Lab vs SellerAmp — The Real Decision
Who Inventory Lab Is Actually For
Inventory Lab earns its $39/month for sellers who are past the beginner stage and need to know their real numbers. The accounting component — actual net profit after COGS — is something neither the Amazon Seller App nor SellerAmp provides. If you're spending $2,000+/month on inventory and tracking profit on a napkin, Inventory Lab closes a significant gap.
Frequently Asked Questions
Inventory Lab is an FBA management tool that combines profit and loss tracking, inventory management, FBA listing creation, and the Scoutify barcode scanner in one subscription. It connects directly to your Amazon Seller account and automatically tracks your revenue, fees, and cost of goods to show your actual net profit per product and in total.
Inventory Lab is worth it for sellers doing $5,000+/month who need accurate accounting and want to track cost of goods (COGS) per unit. For beginners, the Amazon Seller App and a simple spreadsheet (or the PayLaterProfit Starter Kit tracker) are sufficient. Add Inventory Lab when you need real profit tracking across hundreds of SKUs.
SellerAmp is the better mobile scanner for most retail arbitrage sellers. SellerAmp includes Keepa price history, IP complaint flags, hazmat warnings, and a more complete buy-decision interface. Scoutify's main advantage is direct integration with your Inventory Lab account so buys are logged automatically — a genuine time-saver if you're already an Inventory Lab subscriber.
Inventory Lab costs $39/month and includes the Scoutify scanner at no extra charge. This makes it comparable to SellerAmp ($19.99/month) + a separate bookkeeping solution. If you need both scanning and accounting, Inventory Lab's bundled price is competitive.
