Your Amazon dashboard says last month was your best ever: $24,000 in sales, up 30 percent. But your bank balance barely moved, and you cannot say which of your eight products actually made money after referral fees, fulfillment fees, storage, returns, and ad spend. That gap between the sales number Amazon shows you and the profit number you keep is the most expensive blind spot in an FBA business — and the three best-known seller tools each attack a different side of it.
Helium 10, Jungle Scout, and sellerboard are often compared as if they were three versions of the same product. They are not. One is a broad suite that covers research, keywords, listings, ads, and profit in a single subscription. One is a product-research specialist that finds and validates what to sell. One ignores research entirely and tells you, down to the fee line, what you kept on what you already sold. Buying the wrong one for your stage means paying a suite price for a single-tool job — or flying blind on margin while holding a drawer full of keyword data.
This guide compares the three on the jobs that matter: product research depth, keyword and listing tools, and the fee-level profit dashboard. Prices below are the vendors' published rates as checked by independent 2026 roundups; SaaS prices move often, so confirm the final number on the vendor's own page before you buy.
The three jobs, and why one tool rarely does all three well
Every Amazon seller eventually needs three answers:
- What should I sell? Product research: demand, competition, review depth, and whether the numbers work at a realistic price.
- How do buyers find it? Keyword and listing work: which search terms matter, how competitors rank for them, and whether your listing is indexed for the terms you target.
- What did I actually keep? Profit tracking: gross sales minus every fee Amazon takes, minus ads, minus your landed cost, per SKU.
Pre-launch estimates and post-launch reality come from different data. Research tools model a product's margin from public marketplace data before you sell a single unit. A profit tracker reads your own settlement, fee, refund, and advertising data after the fact. The gap between the two is where money goes missing: referral fees of 8 to 15 percent depending on category, per-unit fulfillment fees, monthly storage that roughly triples in the fourth quarter, return processing, and ad spend routinely consume 40 to 60 cents of every sales dollar on a typical FBA product. Sellers who budget from the referral fee and product cost alone discover the rest one settlement report at a time.
That is the lens for this comparison. Judge each tool by the job it was built for, not by the length of its feature list.
Helium 10: the all-in-one suite
Helium 10 is the broadest tool of the three. Its catalog groups roughly into product research (Black Box, Xray), keyword research (Cerebro, with Magnet merged into it), listing optimization (Listing Builder, Listing Analyzer, Index Checker), daily operations (Profits, inventory, alerts, a managed refund service), analytics, and advertising (Helium 10 Ads). If you want one login that stretches from "what should I sell" to "how did my ads perform," this is the only one of the three that tries.
The plan you buy matters more than the tool list, because the entry plan is far narrower than the suite's reputation suggests:
- Platinum runs $99 a month billed yearly, or $129 month to month. It caps keyword research at 100 searches a month across Cerebro lookups, includes no rank tracking (available as an add-on from $19 a month), and excludes Helium 10 Ads entirely.
- Diamond runs $279 a month billed yearly, or $359 month to month. It lifts the keyword research cap, includes rank tracking, and bundles Helium 10 Ads with a 2 percent management fee on ad spend in managed profiles.
Those limits bite in specific ways. A single reverse-ASIN lookup across 10 competitor listings consumes 10 of Platinum's 100 monthly searches, so a seller actively researching a category can burn a month's allowance in an afternoon. And a seller whose bottleneck is "are my rankings moving" gets nothing on Platinum without the add-on. Helium 10's own framing positions Platinum for businesses under $100K in yearly sales and Diamond for the stretch up to $10M — which reads less like upselling and more like an honest map of where the caps start to hurt.
Helium 10 fits the seller who is already launched, already spending on ads, and would rather pay one subscription than stitch together specialists. It is a poor first purchase for a pre-launch seller with no product shortlist, and an expensive answer to the single question "what is my margin," which the Profit tool addresses only in limited form on Platinum.
Jungle Scout: product research depth
Jungle Scout's strength is the first job: finding, validating, and sourcing a product. Its Product Database and Opportunity Finder screen the catalog for niches with demand and manageable competition, the Product Tracker follows shortlisted ASINs over time, and the Supplier Database connects a validated idea to manufacturers. For a seller who has not committed to a product yet, that chain — find, validate, source — is the whole game, and Jungle Scout covers it on one mid-priced plan.
The plan structure rewards reading carefully:
- Starter costs $29 a month billed annually, or $49 month to month. It is a sampler: 100 Product Database and 100 Opportunity Finder searches a month, 50 Keyword Scout searches, one month of keyword history, and no Supplier Database or data exports.
- Growth Accelerator costs $49 a month billed annually, or $79 month to month. It removes the cap on Product Database and Opportunity Finder searches, tracks 150 products, includes 250 Keyword Scout searches a month plus rank tracking, and unlocks the Supplier Database, exports, and listing tools.
Growth Accelerator is the plan the product's reputation rests on, and at $49 a month on annual billing it undercuts Helium 10's entry plan by half while including more usable research. The trade is scope: Jungle Scout covers Amazon marketplaces only, so a seller expanding to Walmart or TikTok Shop needs another data source, and its keyword and advertising depth do not match Helium 10's Diamond tier.
Pick Jungle Scout when choosing the product is the bottleneck — first-time private-label sellers, or established sellers hunting a second or third product. Once the product is live and the question shifts to rankings, listings, and ads, the center of gravity moves elsewhere.
Sellerboard: the fee-level profit dashboard
Sellerboard does not help you pick a product or rank a listing. It answers one question with unusual precision: after every Amazon fee, every refund, every ad dollar, and your cost of goods, what did each SKU actually earn? It computes that from your own account data rather than marketplace estimates, which is exactly the number the research tools cannot give you.
The pricing is the lowest of the three by design:
- Standard is $19 a month, or $179 a year, covering up to 3,000 orders a month. Higher tiers scale by order volume up to 50,000 orders on Enterprise.
- Every plan includes the real-time profit dashboard, PPC profitability views, inventory signals, reimbursement tracking for lost and damaged FBA stock, and listing-change alerts.
- A one-month free trial requires no credit card, which makes it the cheapest experiment on this list: connect the account, see your real margin for a month, then decide.
Why a dedicated tracker earns its place even beside a suite: a pre-launch estimate assumes a fee stack, while a tracker reads the actual one. Long-term storage surcharges on slow movers, inbound placement fees, refund admin fees that Amazon keeps on returns, and PPC spend drifting past breakeven all show up in settlement data weeks before they show up in your intuition. Sellers commonly discover that their best-selling SKU by revenue is a middle performer by profit — or that a product they considered killing is the one carrying the catalog once ad spend is allocated honestly.
Sellerboard fits any seller with live units and unsettled questions about margin — which, frankly, is most sellers past their first quarter. It fits poorly only for pre-launch sellers with nothing to track yet.
How to choose by stage
Name your bottleneck first, then buy the tool that solves it. In order:
You cannot state your real margin per SKU. Buy the profit tracker first. A month of sellerboard's free trial against your own data will teach you more about your business than any research database, and it costs nothing to find out whether your winners are actually winners.
You have not chosen a product yet. Start with Amazon's free tools — Brand Analytics for brand-registered sellers and the Product Opportunity Explorer inside Seller Central report Amazon's own data, which no paid tool can beat for accuracy. When you are screening candidates in bulk, Jungle Scout's Growth Accelerator is the value pick: uncapped product screening plus supplier sourcing for $49 a month on annual billing.
The listing is the bottleneck. If rankings are flat and conversion lags, you need the keyword-to-listing chain: reverse-ASIN research, rank tracking, and indexing checks. That is Helium 10's home turf, but only on Diamond — Platinum's 100-search cap and missing rank tracking make it a frustrating listing tool. Price the $279 accordingly against the revenue a fixed listing would unlock.
You are spending real money on ads. Price PPC tooling against ad spend, not against other tools' subscriptions. Below a few thousand dollars a month, Amazon's free Campaign Manager keeps 100 percent of a small budget working; Helium 10 Ads arrives with Diamond plus its 2 percent management fee. The common mistake is buying breadth to solve a depth problem: a $279-a-month suite for a $19 question, or an intelligence plan when what you needed was a better title.
Two pairings cover most sellers without waste: sellerboard plus Jungle Scout Growth Accelerator for the research-to-launch stretch (about $68 a month combined on annual billing), and sellerboard plus Helium 10 Diamond for the scaling stretch, where rank tracking and ads join profit as daily concerns.
Your profit dashboard is not your books
One caution that applies whichever tool you buy: a profit dashboard and an accounting ledger answer different questions, and neither replaces the other. Sellerboard tells you what you kept this month. Your books must also produce cost of goods sold from landed cost, reconcile every settlement payout to the bank deposit, support your tax return, and survive an audit. Queries run against your ledger, not your dashboard — and the dashboard's numbers assume your entered product costs are right, which is itself a bookkeeping discipline.
The habit that matters is reconciling each Amazon settlement as its own entry: gross sales as income, every fee class as its own expense line, and the net payout to cash. Kept in plain text, a month's settlement looks like this:
2026-01-01 open Assets:Cash:Operating USD
2026-01-01 open Assets:Receivable:Amazon USD
2026-01-01 open Assets:Inventory USD
2026-01-01 open Expenses:Amazon:FBA-Fees USD
2026-01-01 open Expenses:Amazon:Referral-Fees USD
2026-01-01 open Expenses:Amazon:Refund-Admin USD
2026-01-01 open Expenses:Advertising:Amazon-PPC USD
2026-01-01 open Expenses:CostOfSales:COGS USD
2026-01-01 open Income:Sales:Amazon USD
2026-11-01 * "Amazon" "October sales — 100 units at 29.99"
Assets:Receivable:Amazon 2999.00 USD
Income:Sales:Amazon -2999.00 USD
2026-11-01 * "Amazon" "COGS — 100 units at 8.50 landed cost"
Expenses:CostOfSales:COGS 850.00 USD
Assets:Inventory -850.00 USD
2026-11-03 * "Amazon" "October settlement payout, net of fees"
Assets:Cash:Operating 1863.75 USD
Expenses:Amazon:Referral-Fees 449.85 USD
Expenses:Amazon:FBA-Fees 450.00 USD
Expenses:Advertising:Amazon-PPC 210.40 USD
Expenses:Amazon:Refund-Admin 25.00 USD
Assets:Receivable:Amazon -2999.00 USDThree lines deserve attention. The referral fee sits in its own account because rates vary by category, and a blended "Amazon fees" account hides which categories are eating you. PPC is advertising, not an Amazon fee — mixing it into fulfillment costs corrupts both your channel analysis and your tax categories. And COGS books from landed cost (product, freight, prep, inbound shipping), not from the factory quote; the gap between the two is a perennial source of phantom profit.
Once settlements book this way, the payoff compounds. A dashboard-style view over the ledger — Fava renders income statements and charts straight from the file — lets you compare the tracker's live margin against the ledger's audited margin and investigate when they disagree. That disagreement is usually the most valuable signal either tool produces: unclaimed reimbursements, misallocated ad spend, or a landed cost that drifted since you entered it. The docs walk through setting up this structure from your first settlement file.
Mistakes to avoid
A few patterns recur across seller forums and teardown guides:
- Trusting pre-launch estimates after launch. The estimate that justified the product assumed a fee stack and a conversion rate. Six months later the fees changed, storage tiered up, and returns ran hotter than the category average. Re-validate every SKU against settlement data quarterly.
- Budgeting from revenue instead of payout. A $29.99 sale is not $29.99 of income; after a 15 percent referral fee, roughly $4.50 in fulfillment, storage, and ads, the cash event is closer to $18. Price, reorder, and ad decisions should all start from the payout figure.
- Letting reimbursements leak. Lost and damaged FBA inventory, overcharged fees, and unreturned customer refunds are recoverable — but only if someone files the claims. Both Helium 10 and sellerboard flag candidates; an unmonitored account donates this money to Amazon permanently.
- Hitting Platinum's keyword cap by surprise. If you buy Helium 10 for keyword depth, count your searches in week one. Ten-ASIN Cerebro runs against a 100-search monthly allowance disappear fast, and discovering the cap mid-project is how sellers end up paying for Diamond in a panic.
- Skipping the free tier of the funnel. Amazon's own Brand Analytics and Product Opportunity Explorer cost nothing and report first-party data. Whatever you buy, check its claims against the free source before acting on them.
Your next step this week
Pull your most recent Amazon settlement report and compute one number by hand: net payout divided by gross sales. That ratio — typically somewhere between 0.40 and 0.60 for FBA sellers once ads are included — is your business's real take rate, and every tool decision flows from whether you trust it. If you cannot compute it, start the profit tracker's free month today; if you can but do not like it, the fee lines will tell you whether the fix is pricing, ads, or the product itself. Either way, you will be deciding from your own data instead of a dashboard's estimate — which is the entire point.
