E-commerce & Marketplace Tools

Research, list, and fulfill on Amazon and TikTok Shop without fifteen browser tabs open. These are the tools we have actually used to source products, track competitors, and automate the parts of selling that do not need a human doing them by hand.

Helium 10Best for: Amazon FBA sellers doing full research and PPC

The deepest Amazon research stack available, keyword tracking, listing optimization, and PPC management in one place. Pricing jumped in 2026 and the interface takes real time to learn.

Pros

  • All-in-one suite, most sellers never need a second tool for Amazon research
  • A limited free plan exists to try the core tools before paying
  • Large training and community ecosystem

Cons

  • Entry paid plan is now $99/month (Platinum), the old $39 Starter plan is gone
  • Steep learning curve, budget a real weekend to get comfortable with it

KalodataBest for: TikTok Shop sellers researching viral products

Tracks TikTok Shop products, creators, and videos down to individual view counts, so you can see what is actually selling before you commit inventory to it.

Pros

  • 200M+ creator profiles and 400M+ video records, TikTok-specific depth Amazon tools do not have
  • Tracks livestream and video-level performance, not just product listings
  • 7-day free trial, no credit card required

Cons

  • TikTok Shop only, no Amazon data if you sell on both
  • $45.90 to $99.90/month before you have made a sale on the platform

Pros

  • Connects to Shopify, eBay, Wix, and WooCommerce plus 25+ suppliers
  • Automatic price and stock monitoring so listings do not go stale
  • Social-spy tool shows which products competitors are actively advertising

SmartScoutBest for: Wholesale and online arbitrage sellers doing brand research

An Amazon market-intelligence platform that tracks over 1.5 million brands, built for finding under-served brands and running bulk profitability checks, not for private label product discovery.

Pros

  • Brand-level data most tools do not track: revenue estimates, FBA seller count, Buy Box pricing
  • UPC bulk scanner checks thousands of distributor SKUs against Amazon in one pass

Cons

  • No free trial, only a 7-day money-back guarantee
  • Built specifically for wholesale and arbitrage, less useful if you are doing private label

Seller AssistantBest for: Wholesale and arbitrage sellers who want research and sourcing together

Shows FBA and FBM margin directly on the product page, fees included, and its Price List Analyzer can check up to 20,000 ASINs from a distributor list at once.

Pros

  • Restricted products get flagged before you place a purchase order, not after
  • Sub-accounts let a VA run sourcing without access to your Seller Central login
  • 14-day free trial

Cons

  • The bulk-research tools are built around distributor price lists, less useful outside wholesale sourcing

CJdropshippingBest for: Dropshippers who want sourcing and fulfillment handled for them

Sources from Chinese manufacturers, stores inventory in its own US, EU, and Asia warehouses, and ships to your customer, so you are not relying on a single overseas seller for fulfillment speed.

Pros

  • Base plan has no monthly charge, unlimited listings and automated fulfillment included
  • Warehouses outside China mean faster delivery than direct AliExpress-style sourcing
  • One-click import to Shopify, WooCommerce, and eBay

Cons

  • Product quality and shipping time still vary by which supplier CJ sources from
  • VIP product access and higher sourcing-request limits need a paid tier ($16 to $60/month)
