Amazon 出品者向けツールのトップ3

sellerboard comes first because most small sellers need to know their profit, and it adds stock planning, review requests and lost-stock claims from $15 a month billed yearly. Helium 10 is second for sellers still finding a product. Keepa is third for resellers checking price and sales rank history; it grades higher than sellerboard on free use and its phone app, but it is data only. Carbon6 narrowly missed: ManageByStats has a free profit dashboard, but its other tools are priced one by one. Jungle Scout's research costs $29 a month billed yearly, with no free trial.

   無料トライアル · $15/月 から

   Most small Amazon sellers 向け

   sellerboard counts Amazon fees, ad spend, refunds, product costs and other expenses to show net profit by product and order. Every plan adds inventory forecasts, review requests, PPC optimization, listing change alerts and claims for lost FBA stock, and it also connects to Shopify, Walmart and eBay. Standard is $15 a month billed annually at $179 ($19 monthly) for up to 3,000 orders a month, after a 1-month free trial with no card. It runs on the web, iPhone, Android and as a browser extension. Know the limits: there is no product or niche research, no free plan after the trial, and limiting each user's access needs Enterprise at $63 a month.

   2位: Helium 10

   無料プラン · $99/月 から

   Sellers still looking for a product to launch 向け

   Helium 10 covers product research with Black Box and Xray, keyword research with Cerebro and Magnet, an AI listing builder, rank tracking, profits, inventory, review requests and FBA refund claims, and reaches Walmart and TikTok Shop too. A free account with limited uses of each tool has no end date, and Platinum, for up to $100K a year in sales, is $99 a month billed annually ($129 monthly). It is second because Platinum is mostly research, with 20 tracked ASINs and 40 inventory SKUs, while ad automation and profit and loss reports need Diamond at $279 a month. It runs on the web and a Chrome extension only.
