Best tools for Amazon FBA sellers in 2026

Sellerboard takes first place because it answers the question every FBA seller eventually asks: after referral fees, FBA fees, storage, ad spend, refunds and your cost of goods, what did you actually make on each product? Revenue in Seller Central looks great. Profit is a different number, and Sellerboard shows it in a real-time dashboard per product, per marketplace and per period.

The Standard plan costs $19 a month, or $15 a month billed yearly ($179 a year). It covers 3,000 orders a month, 150 review request emails a month, 4 extra seller accounts, 1 extra user and 3 automated reports. Professional, at $29 a month ($23 billed yearly), doubles the order limit to 6,000 and raises review emails to 6,000. Business ($39) goes to 15,000 orders and 4 users. A solo seller under 3,000 orders a month can stay on Standard.

Beyond profit, the feature list covers listing change alerts, PPC optimization, a repricer for FBA and FBM, inventory management, an LTV dashboard and lost inventory reimbursements. The pricing page doesn't make it clear which of these sit in which plan, so check the plan grid before you count on the repricer. Sellerboard is a Germany-based company founded in 2017, it works with all Amazon marketplaces and it reports more than 20,000 sellers. Accounts top out at 30,000 products.

The limits are honest ones. There's no product research and no keyword tool, so it won't help you find what to sell. And reviewers describe a dashboard that gets slow, with filters that reset themselves. It still holds 4.5 out of 5 across 162 reviews on a large review site, with most praise for clear profit numbers at a low price.

Helium 10 is the broadest toolbox on this page: product research, keyword research, listing builder, keyword tracking, follow-up emails, inventory management, fraud alerts, reimbursements, plus an ads module on Diamond. For a private label brand that lives on keywords and listings, nothing else here covers as much ground. That's why it ranks second, ahead of tools that do one job well.

The catch is the price, which went up in 2026. Platinum now costs $129 a month, or $99 a month billed yearly (a $360 saving over the year). Sellers on review sites note that it used to be $99 a month, and that you can no longer buy single tools on their own. Platinum is also tighter than its name suggests: Market Tracker is limited to 3 tracked markets and detailed analytics to 20 of your ASINs, with 2 Seller Central accounts, 100 keyword searches a month, 50 competitor listing analyses a month and 40 SKUs in inventory management. Diamond, at $359 a month ($279 billed yearly), lifts that to 5 tracked markets, 1,000 ASINs, 10 accounts and 500 SKUs.

Two fees hide below the plan price. The managed reimbursement service takes a 15% commission on Platinum (10% on Diamond). And Helium 10 Ads, which requires Diamond, charges 2% of the ad spend it manages. One seller on a sellers' forum worked out that the 2% would cost a small US account about $3,000 more a year. Add-ons start at $19 a month if you need more keyword tracking.

The free plan exists, but it only gives limited access to the Chrome extension. On a large review site Helium 10 sits at 2.0 out of 5 across 716 reviews, with complaints about the price rise, a yearly renewal charged without a reminder, refunds refused and data lost after cancelling. That record is why it scores 3.0 on billing and transparency, the second-lowest mark on this page.

Jungle Scout is the easiest way into product research. Its Starter plan costs $49 a month, or $29 a month billed yearly ($348 a year), which ties it with SmartScout as the cheapest research tool on this page on yearly billing. You get the browser extension, 50 tracked products with 30 days of history, 500 sales estimates a month, 100 searches a month in Opportunity Finder and the Product Database, and 50 keyword searches a month.

Read what Starter leaves out, though. There's no export, no inventory management, no FBA reimbursements, no ad analytics and no automated review requests. Those all arrive with Growth Accelerator at $79 a month ($49 billed yearly), along with the Supplier Database and 150 tracked products. If your plan is to manage stock and claims in Jungle Scout too, Starter is the wrong plan, and Sellerboard at $19 may be the better partner for it.

Jungle Scout's Catalyst plans cover 8 marketplaces: the US, Canada, Mexico, the UK, France, Germany, Italy and Spain. Some features stay US-only, and its euro price list shows 1 marketplace on Starter, 3 on Growth Accelerator and 10 on Brand Owner, so check how many your plan includes. Extra seats cost $49 a month on Growth Accelerator and Brand Owner.

There's no free trial. The US pricing page offers a 7-day money-back guarantee instead (its euro price list says 14 days), and sellers call it rigid: refunds are only possible within seven days of the charge. On a yearly plan that means the whole year is charged upfront. Its public score holds at 4.0 out of 5 across 3,940 reviews, but only a handful are recent, and some describe sales estimates that don't match reality.

Keepa does one thing, and almost every FBA seller keeps it open: it shows the price history, sales rank history and Buy Box history of any Amazon product. Before you send 300 units to a warehouse, a Keepa chart tells you whether that price holds all year or only spikes in December, and whether the rank you see today is normal or a one-week accident.

Keepa doesn't publish a readable pricing page, so take the numbers here as approximate. Sellers who pay describe a subscription of about €29 a month, billed in euros, so your card will convert it. In 2026, the free tier changed: users report that free tracking dropped from several thousand products to 200, and many recent one-star reviews are about exactly that.

Resellers who check dozens of products a week usually outgrow the free tier. Complaints are about money and lag, not about the charts: no refund after a yearly renewal, disputed charges, and data that sometimes lags or looks wrong. Its review profile is small and unsolicited (1.6 out of 5 across 45 reviews), so don't read too much into it. The positive reviews say the same thing in different words: they use Keepa every day.

SellerAmp SAS is the tool resellers open on every product they look at. You land on a product, and it shows the profit, the ROI, whether you're allowed to sell it, and how the Buy Box behaves. For someone scanning dozens of products an hour in a store aisle or on a retailer's website, that speed is the whole point.

Pricing is simple. Getting Started costs $19.95 a month, Getting Serious $29.95 and Going Pro $49.95, and paying yearly gives you two months free. Every plan includes the same core features: profit calculator, alerts, charts, Buy Box analysis, the Chrome extension, a web app and a mobile app. You can try any plan for 14 days and cancel at any time.

Its pricing page lists 7 supported marketplaces: the US, the UK, Canada, France, Spain, Germany and Italy. That matters if you source in one country and sell in another.

What holds its score back is a thin public record: only 3 reviews on a large review site, too few to say much about billing or support either way. And it's built for resellers. A private label brand with five products of its own will get little from it.

SmartScout is built for the wholesale question: which brands are worth emailing for an account, and which of their products would sell. Its data is strongest on Amazon US. The Basic plan includes 5,000 ASIN lookups a month, the browser extension, review requests, a price list scanner (paste a supplier's file, see which items could sell) and a sales estimator.

Basic costs $49 a month, or $29 a month billed yearly. Essentials is $119 ($99 yearly) and Business $299 ($239 yearly), with Enterprise on quote. Every plan comes with a 7-day money-back guarantee.

Coverage of European marketplaces is unclear from what the vendor publishes, so if you sell mainly on Amazon UK or Germany, ask before paying. For a private label seller hunting a first product, Jungle Scout is the simpler pick.

InventoryLab has long been a reference for US resellers who list and ship a high volume of FBA inventory. It costs $69 a month, or $58 a month billed yearly (a $138 saving), with unlimited users, which helps if a family member or a prep assistant works on the account. A Restocking Insights module costs $25 a month on top. The 30-day free trial matches Sellerboard's free month.

The big limit is geography. InventoryLab's help center states that it only supports the Amazon.com US platform. If you sell on Amazon UK, Canada or Europe, it isn't for you.

Its ownership changed too. InventoryLab now belongs to Threecolts and is also sold inside the Seller 365 bundle (Standard at $69 a month, or $65 billed yearly, with a 14-day trial). Users describe the price doubling from $35 to $70 a month, slower support and a drop in quality since the acquisition. The public review count is small, 7 reviews at 2.9 out of 5, so treat it as a warning sign rather than a verdict.
