InventoryLab handles FBA shipment creation, cost tracking and profit reporting, and includes the Scoutify 2 scanning app. It is now sold only as part of the Threecolts Seller 365 bundle. It is popular with retail arbitrage and wholesale sellers who want accurate profit numbers.
Jungle Scout is an Amazon research suite covering product research, sales estimates, keyword research, supplier database and listing optimisation. It is aimed at sellers launching their own products or sourcing wholesale.
Retail and online arbitrage on Amazon live and die by data: sales rank, price history, Buy Box competition, fees and ungating restrictions. These tools range from free browser extensions to full research suites. Beginners usually start with one scanner app plus Keepa, and add a sourcing suite once they are consistently profitable. The deciding factors usually come down to each tool's standout strength (for InventoryLab: accurate fba profit tracking; for Jungle Scout: comprehensive amazon research) weighed against its main drawback (amazon-only versus overkill for casual arbitrage).
