Threecolts Seller 365

Verdict: the best-value toolkit for arbitrage and wholesale sellers, because it bundles the sourcing, listing, and repricing tools they would otherwise buy one by one. Private-label brands should look at the specialist tools instead.

What’s in the bundle

Seller 365 is Threecolts’ subscription to its own portfolio of Amazon seller tools, sold as one login:

• Tactical Arbitrage: sourcing across 1,400+ retailers, plus wholesale and book searches.
• ScoutIQ, Scoutify, ScoutX: mobile and browser scanning for books and in-store finds, with profit, ROI, fees, and sales rank.
• InventoryLab and InventoryLab Accounting: listing, FBA shipment building, inventory, and bookkeeping-ready sales data.
• SmartRepricer: automatic repricing against competing offers.
• FeedbackWhiz Emails, Alerts, Profits: review and feedback requests, alerts for hijackers and Buy Box changes, and a profit dashboard.
• Seller 365 Reimbursements: recovery of money Amazon owes for lost or damaged inventory, charged as a commission.

Every plan also includes AI Operator, an assistant that runs tasks inside the connected tools, with a monthly usage allowance.

Brands plans (Seller 365 plus UniCon multichannel, aimed at private label) run from $149/mo annually (Brands 1K) to $999/mo (Brands 10K). UniCon can be added to a reseller plan from $49/mo. All plans have a 14-day free trial: 7 days at signup and 7 more when you connect your Amazon or Walmart seller account. Some limits on the pricing page conflict with its own plan descriptions, so check the comparison table for the number that matters to you before buying.

Who it is for

The math works for resellers. Tactical Arbitrage, InventoryLab, and a repricer are the core stack for online arbitrage and wholesale, and buying them separately costs more than Seller 365 Standard. For a private-label brand with a few dozen ASINs, most of the bundle has nothing to do; the research and keyword work is better covered by SmartScout, Helium 10, or Data Dive, and repricing rarely matters when you are the only seller on your listings. If repricing is the job you need, compare SmartRepricer with Aura and Seller Snap.
