The 12 tools, reviewed
#1 sellerboard
Profit analytics for Amazon sellers, priced by order volume. · Germany · sellerboard.com
Profit analytics Margin tracking EU vendor
This is the tool that answers the question most small sellers actually have: what did I keep? It nets out Amazon's fees (the vendor cites more than 100 of them), refunds, advertising and your own purchase costs, then shows profit by product and day.
- Pricing: Per order-volume tier / month. Four tiers by monthly order volume, listed from $19 (3,000 orders) to $79 (50,000 orders) on monthly billing, with cheaper annual rates and a one-month trial. Free plan: free trial.
- Best for: Small sellers tracking real margin
- Strengths: Profit dashboard; COGS management with FIFO; Returns statistics.
Where it falls short
The extras around the dashboard, such as the repricer and PPC rules, are lighter than dedicated products. It does not offer a product database for finding what to sell.
Wrong for
A seller who has no product yet, or one who wants a full product database and rank tracker before launch, should start with a research suite.

#2 SmartScout
Amazon market intelligence organized around brands and sellers. · United States · smartscout.com
Market research Brand data Seller data
Most research suites start from a product or keyword. SmartScout starts from the market: which brands sell in a subcategory, which sellers carry each brand's ASINs, and how fast each is growing. It covers 40,000+ subcategories that do not appear in Amazon's public browse tree, and its Traffic Graph shows how shoppers move between related products.
- Pricing: Tiered / month. Basic, Essentials and Business tiers listed between $29 and $299 a month depending on tier and billing period, a custom Enterprise plan and a 7-day money-back guarantee. Free plan: none.
- Best for: Brand-level market research
- Strengths: Brand-level revenue estimates; Subcategory explorer; Traffic Graph.
Where it falls short
The view is US-native and built around estimates, so figures for rivals stay approximations. Seller-level and sub-category data sit in the upper tiers, and some of the more practical modules are in the Essentials plan or above.
Wrong for
A seller who needs margin tracking or advertising automation will find little here; look at sellerboard or Perpetua.

#3 Keepa
Amazon price and sales-rank history charts. · Germany · keepa.com
Price tracking History charts API
Keepa does one thing and keeps its scope narrow. Open any product and it shows how price, sales rank and offer count moved over time, so a seller can see whether a competitor's sales spike was a one-day coupon, whether a sourcing target sells in summer only, and whether the Buy Box price has been sliding.
- Pricing: Free + paid subscription. A free tier with charts and a paid data subscription for deeper tracking and API use, billed in euros. Free plan: free plan.
- Best for: Checking price history and trends
- Strengths: Price history charts; Sales rank history; Price drop alerts.
Where it falls short
It tracks public listing data and shows no profit, fee or advertising figures from your own account. Sales volumes are inferred from rank movements, not reported.
Wrong for
A seller wanting keyword research, listing scores or account analytics should look at Helium 10 or sellerboard.

#4 Helium 10
Large all-in-one research and operations suite. · United States · helium10.com
All-in-one Keyword research Listing tools
Helium 10 is the name most Amazon sellers know, and the breadth justifies it. Xray estimates a product's sales, Cerebro reverse-searches a competitor's keywords, Black Box filters a product database, and the Profits and Ads modules reach into daily operations. The pricing page lists a Free plan with limited access, so a newcomer can try the extension without paying.
- Pricing: Tiered / month. Platinum is listed at $129 a month ($99 on yearly billing), Diamond at $359 ($279), Enterprise from $1,499 a month billed annually, plus a limited Free plan. Free plan: free plan.
- Best for: Sellers wanting one broad suite
- Strengths: Xray; Cerebro; Magnet.
Where it falls short
Its breadth means each module is shallower than a specialist, and the profit and ad tools trail dedicated products. Diamond costs nearly three times Platinum on monthly billing. The interface has many tools and a steep learning curve.
Wrong for
A seller who only needs a margin dashboard will pay for modules never used; sellerboard fits better.

#5 Jungle Scout
Research suite for sellers, plus enterprise brand analytics. · United States · junglescout.com
Product research Brand analytics Enterprise option
Jungle Scout splits its offer by company size. Catalyst, aimed at sellers under $1M in annual revenue, bundles product research, keyword research and tools for launching and getting reviews. Cobalt, aimed at brands above that, adds category benchmarking, share-of-market views and a dedicated customer success manager. The vendor states it has more than a million customers and 11 years of sales-estimate refinement.
- Pricing: Tiered + per seat / month. Catalyst plans for sellers under $1M in revenue include Starter, Growth Accelerator and Brand Owner tiers, extra seats cost $49 a month, and there is a 7-day money-back guarantee instead of a trial. Free plan: none.
- Best for: New and growing private-label sellers
- Strengths: Product database; Keyword research; Sales estimates.
Where it falls short
There is no free trial, only a refund window of seven days, so you pay before you learn how your category behaves. Estimates are modeled and not exact.
Wrong for
A seller on a tight budget who wants a free tier should compare Helium 10 or SellerApp.

#6 SELLERLOGIC
Repricer, analytics and reimbursement tools from Düsseldorf. · Germany · sellerlogic.com
Repricer Analytics EU vendor
SELLERLOGIC is the closest thing here to an operations back-office from Europe. The Repricer adjusts offers automatically, Business Analytics shows profit, Review Manager handles feedback, and Lost & Found chases reimbursements for lost or damaged FBA stock.
- Pricing: Freemium + paid tiers. A Freemium tier gives permanent access to Repricer, Business Analytics and Review Manager, a 14-day trial unlocks premium features, and Lost & Found runs under a separate service agreement. Free plan: free plan.
- Best for: Sellers on Amazon EU marketplaces
- Strengths: Repricer; Business Analytics; Review Manager.
Where it falls short
Paid prices are not published on the pages we read, so budgeting means a conversation. It offers no product research, so you will need a second tool for launch decisions.
Wrong for
A seller choosing what to launch needs a research suite such as Jungle Scout.
Visit SELLERLOGIC →
#7 SellerApp
Research, analytics and ad automation with agency options. · United States · sellerapp.com
Research Ad automation Agency services
SellerApp offers a free entry point and two paid steps, and then a model few rivals have: an agency program from $300 plus a share of ad spend, and managed services starting at $750 a month. The Pro tier adds keyword tracking and listing quality checks, while the Smart tier brings ads automation, a dedicated account manager and a quarterly review.
- Pricing: Tiered / month. A Freemium plan costs $0, Pro starts at $99 a month, Smart (with ads automation) starts at $149, a custom plan is by quote, and the FAQ says annual billing saves 50%. Free plan: free plan.
- Best for: Sellers and agencies wanting a free tier
- Strengths: Product research; Keyword tracking; Listing quality.
Where it falls short
The mix of self-service and service work makes the product line harder to compare. Several services are priced from starting points that depend on negotiation. The free tier is thin, and its profit analytics lag behind sellerboard.
Wrong for
A seller wanting only a margin dashboard has no reason to pay for agency features.

#8 AMZScout
Product finder with profit scores and supplier links. · United States · amzscout.net
Product finder Chrome extension AI chatbot
AMZScout is built for the moment before a launch. On any Amazon page its extension shows a private-label score, a reselling score, estimated monthly sales and a profit estimate, and it points to Alibaba suppliers. A built-in chatbot answers selling questions, and an MCP connection feeds live Amazon data to Claude or ChatGPT. The vendor says it began in Philadelphia in 2017.
- Pricing: Subscription. Sold as paid subscriptions per tool bundle, with the current price list shown on its pricing page. Free plan: none.
- Best for: First-time product hunters
- Strengths: Product Database; Chrome extension scores; Profit estimates.
Where it falls short
It offers little for running a live business: no profit dashboard fed by your account and no ad management. Scores compress several judgments into one number that you cannot audit. Read the renewal and cancellation terms before subscribing.
Wrong for
A seller who already has products and needs margin and ad control should skip it for sellerboard or Perpetua.
Visit AMZScout →
#9 Sellerise
Profit, keyword and reimbursement tools in one subscription. · United States · sellerise.com
Profit analytics Keywords Reimbursements
Sellerise bundles finance and keyword work in one place. Its Sales and Profit, Profit and Loss and Payouts modules cover the numbers an owner reviews each month, Keyword Tracker and SQP Insights handle search terms, and a Review Requester automates feedback emails.
- Pricing: Subscription tiers. Monthly subscription tiers; reimbursement recovery is included in every plan with no percentage fee, according to the vendor's FAQ. Free plan: none.
- Best for: Cost-conscious sellers wanting bundled tools
- Strengths: Sales and Profit; Profit and Loss; Payouts.
Where it falls short
Plan prices did not load on the pages we read, so confirm what is included before committing. It is a smaller player than Helium 10 or Jungle Scout, with a shorter public track record.
Wrong for
A brand running large ad budgets needs a bid platform like Perpetua.

#10 ZonGuru
Listing monitoring and AI-readiness scoring for Amazon. · United States · zonguru.com
Listing monitoring AI readiness Alerts
ZonGuru has moved its pitch toward keeping listings healthy and readable by AI shopping assistants. Each plan monitors every managed listing, raises alerts when content or offers change, and connects through the Selling Partner API. A free AI Readiness Score rates a live listing before you pay, which doubles as a quick audit.
- Pricing: Per managed listing tier / month. Starter at $149 a month, Growth at $299 and Pro at $699 on monthly billing, priced by managed listings. Free plan: none.
- Best for: Brands guarding a small core catalog
- Strengths: Listing monitoring; Change alerts; AI Readiness Score.
Where it falls short
The entry price is higher than most tools here, and the listing caps are low for large catalogs. It does not show profit or ad data. No trial is mentioned on the pricing page, only the free score.
Wrong for
A seller with hundreds of SKUs will hit the limits quickly; SellerApp or sellerboard scale more cheaply.

#11 Teikametrics
Advertising and inventory automation for Amazon and Walmart. · United States · teikametrics.com
Advertising Walmart Refunds recovery
Teikametrics runs advertising for sellers on Amazon and Walmart, with a strategic suite it calls ARI covering ads, catalog, inventory and insights. The Essentials tier carries a price tag and a free trial, and the higher tiers add DSP, Walmart Onsite Display, an Amazon Marketing Cloud connection and optional managed services.
- Pricing: Ad-spend tiers / month. Essentials costs $149 a month on annual billing or $179 monthly for up to $10K in ad spend, with a free trial. Free plan: free trial.
- Best for: Sellers spending up to $10K on ads
- Strengths: Ads automation; Catalog tools; Inventory insights.
Where it falls short
Costs rise with ad spend, so the platform gets pricier exactly when you scale. Higher tiers are custom-priced, and the page is inconsistent on the Enterprise threshold.
Wrong for
A seller with a tiny ad budget gets more from sellerboard's lighter PPC rules.
Visit Teikametrics →
#12 Perpetua
AI-driven bid and campaign management for Amazon ads. · United States · perpetua.io
Advertising Bid automation Enterprise
Perpetua is the most expensive entry on this page, and it is honest about why: it is an ad engine, not a research suite. You set objectives such as growth or profitability, and the platform handles campaign creation, keyword harvesting and bid changes, with hourly reporting and intraday optimization on the Growth tier. Premium adds competitor intelligence, custom AMC reporting and dashboards.
- Pricing: Monthly fee + % of ad spend. Essentials is $695 a month for up to $10K in monthly ad spend, Growth adds a percentage of spend above that, and Premium is custom for spend above $500K. Free plan: none.
- Best for: Brands with larger Amazon ad budgets
- Strengths: AI bid optimization; Automated keyword harvesting; Profitability reporting.
Where it falls short
The entry price is out of reach for small sellers, and there is no trial, so you must book a demo first. The page references only Amazon, so multi-marketplace sellers need to ask.
Wrong for
A seller under $10K a month in ad spend should use lighter automation inside sellerboard or SellerApp.

What the data says about this market
Our list holds twelve products. Nine are headquartered in the United States (Helium 10, Jungle Scout, SmartScout, AMZScout, SellerApp, Sellerise, ZonGuru, Teikametrics and Perpetua) and three in Germany (sellerboard, Keepa and SELLERLOGIC). Seven print an actual price on their public pages: sellerboard, SmartScout, Helium 10, ZonGuru, SellerApp, Teikametrics and Perpetua. Three offer a permanent free tier, namely Helium 10, SellerApp and SELLERLOGIC, while sellerboard and SELLERLOGIC also run a time-limited free trial. That mix says the research end of the market competes on price transparency and free entry, and the advertising end stays sales-led.

Questions and answers
What is the best Amazon seller tool in 2026?
sellerboard ranks first of 12, best for small sellers tracking real margin. SmartScout is second (brand-level market research) and Keepa third (checking price history and trends). Places 1 to 3 go to challengers, vendors outside the best-known brands, wherever the category has them.
Do I need a research tool and a profit tool, or can one product do both?
Plenty of sellers get by with one. Helium 10 covers research, listings and a profits dashboard, and Sellerise mixes profit with keyword tracking. In practice the dedicated tools go deeper on their own job.
How accurate are the sales estimates in product research tools?
They are modeled, not measured. Vendors infer units from sales rank, category and their own panel data, and Amazon shares exact figures only with the account owner.
What does a profit analytics tool need from me to be accurate?
Landed cost per SKU is the main input, meaning product price plus freight, duties and prep. Without it the dashboard shows revenue minus Amazon fees, which flatters every product.
Is Keepa worth using next to a larger suite?
Often yes, because it covers a different question. A suite estimates how a product sells today, while Keepa shows how price, offer count and sales rank behaved over months.
How are Amazon seller tools priced, and which model is cheapest at scale?
Four meters appear: order volume (sellerboard), tiers with user seats (Helium 10, Jungle Scout), managed listings (ZonGuru) and ad spend (Teikametrics, Perpetua). Order-based and ad-spend pricing grow with your business, so they are cheapest while small.
Are there Amazon seller tools from European companies?
Yes, three on this list are German: sellerboard (profit analytics), Keepa (price tracking) and SELLERLOGIC (repricer, analytics and reimbursements). That does not mean they handle only European marketplaces, but a German contracting entity can simplify GDPR paperwork.
Is it safe to connect a seller account through the Selling Partner API?
Connecting uses Amazon's own authorization flow, so you grant read access to chosen data and can revoke it in Seller Central.
What should I check before enabling an MCP connection to an AI assistant?
Several vendors on this list now offer MCP access so an assistant can query their data.
When does it make sense to hire an agency instead of buying a tool?
When ad spend or catalog size has outgrown the hours you can give it. SellerApp runs an agency program from $300 plus a share of ad spend, and Teikametrics offers Managed Services as an add-on.
How do I move from one Amazon seller tool to another without losing history?
Export what you can before you cancel: cost-of-goods uploads, profit reports as spreadsheets, keyword lists and ad rules documented by hand. sellerboard offers spreadsheet export and SELLERLOGIC offers API access, but market estimates and learned bid models do not travel.
