Which one is for you
Pick Helium 10 if
- Fits if you're launching private label products and want research and profits in one account
- Works for sellers branching out from Amazon to Walmart or TikTok Shop
Look elsewhere if
- Pricey if you want ads automation or profit and loss reports, which start on Diamond at $279
- Skip it if all you need is a profit dashboard, as sellerboard starts at $15
- Tight if you're on Platinum: 20 tracked ASINs, 40 SKUs, and a forced move to Diamond past $100K a year in sales
- Watch out: Helium 10 Ads takes 2% of managed ad spend, and the refund service keeps 15% on Platinum
- Watch out: add-ons cost extra, with tracked keywords from $19 a month, MCP from $50 and Market Tracker 360 from $650
Pick SellerEngine if
- Fits if you scout stock with your phone and reprice with the same company's tools
- Works for sellers with under 20,000 items on BuyBoxBuddy
Look elsewhere if
- Skip it if you need Sellery's price, because the pages we read don't show it
- Tight if you stay free: it's 20 scans, then a trial
- Pricey if you want both scouting and batch, since the mobile and batch plans add up
- Watch out: BuyBoxBuddy's three price tiers beyond the $50 entry aren't shown
How we grade them
| 2.4GPAHelium 10Fair | 2.2GPASellerEngineFair | |
|---|---|---|
| Value for money | CPlatinum, the plan for sellers under $100K a year, is $99 a month billed annually ($129 monthly). That's inside the normal range here, but it's mostly research. Ads automation, profit and loss reports and the AI agent need Diamond at $279. | CScouting app $9.99 a month, batch tool $49, BuyBoxBuddy from $50. The category's middle is $37, so the repricer lands in the ordinary band. |
| Free plan and trial | CA free account with no end date, but with limited uses of each tool and of the Chrome extension, for one user. Enough for a look round, not for running a store. | CTwo-week trial on Sellery, 15 days on BuyBoxBuddy, both with no card, plus 20 free scans on the app. |
| Features | BBlack Box and Xray for product research, Cerebro and Magnet for keywords, an AI listing builder, rank tracking, profits, inventory, review requests, refunds and ads. It covers the whole job and reaches Walmart and TikTok Shop, though ads and P&L need Diamond. | CTwo repricers plus a scouting app and batch tool. Analytics and shipping options in Sellery are enterprise extras set up on request. |
| Ease of use | CNo rating on record. It's a big suite with a lot of separately named tools to learn, and seller and ad accounts to connect before most of it works. | CNo store rating on record. You connect your Amazon account and set repricing rules. |
| Platforms and integrations | BWeb and a Chrome extension, with no phone or desktop app on record. It connects to Seller Central, Amazon Ads, Walmart and TikTok Shop, and its MCP lets Claude and other AI tools query your data. | BWeb, plus iPhone and Android apps for scouting. |

More comparisons
How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
