One-view research

Everything you need to make the call, without opening another tab.

True cost

Profit after every Amazon fee, before you commit to a buy.

ScoutX calculates true costs upfront — all Amazon fees and category-specific charges included. Separate FBA and FBM calculators show both options side by side, so the comparison matches the fulfillment method you actually use.

  • All Amazon fees accounted for, not estimated.
  • Category-specific charges included upfront.
  • Separate FBA calculator for fulfilled-by-Amazon costs.
  • Separate FBM calculator for merchant-fulfilled costs.

From research to action

Research that flows straight into your workflow.

  • Export to Google Sheets in one click.
  • Add directly to InventoryLab unlisted inventory.
  • No data entry between research and listing.
  • Research done — your inventory pipeline already has it.
