ManageByStats Review (2026): The All-in-One Amazon Seller Suite, Honest Pros & Cons

ManageByStats is a broad Amazon seller suite — profit-and-loss reporting, statistics, a customer database, advertising data, product research, supply chain, and the SellerMail email module — now owned by Carbon6, which SPS Commerce acquired in February 2025. Our verdict: the modules are genuinely wide and the official documentation is still public and detailed, but two things should slow you down in 2026 — the recurring, independently repeated complaints that its numbers do not reconcile, and the fact that ManageByStats no longer publishes a readable pricing or feature page at all. Every public marketing URL we checked on 2026-07-25 redirects to a Carbon6 login screen, which means you cannot confirm what you will be charged before you hand over an email address.

How this review was produced, plainly: we do not have an Amazon Seller Central account and we have not used ManageByStats. This is a desk review built from ManageByStats’ own public knowledge base, its Chrome Web Store listing, SPS Commerce’s investor announcements, dated third-party review pages, and verified public user reviews. There are no screenshots of the logged-in product here and no claims about what it feels like to run day to day. All checks below are dated, and the URLs are cited so you can repeat them.

The 2026 situation you need to know first

Start here, because it changes how you shop. On 2026-07-25 we followed each public ManageByStats URL with an automated HTTP check:

So the marketing site is gone but the ManageByStats knowledge base is intact and remains the best first-party source about the product. That combination is unusual, and it is worth reading as a signal rather than a conspiracy: the product is clearly still operating and documented, but nobody is currently selling it to you on a public web page.

The ownership chain explains part of it. SPS Commerce announced on 2025-01-02 that it would acquire Carbon6 “for a total purchase price of approximately $210 million (subject to customary purchase price adjustments at closing)” and completed the acquisition on 2025-02-07 . Both releases describe Carbon6 as “a provider of software tools to Amazon sellers, including specialized offerings for revenue recovery for both first-party (1P) and third-party (3P) suppliers.” The January announcement names two Carbon6 products specifically — ChargeGuard and Seller Investigators — and ManageByStats is named in neither release. That does not prove ManageByStats is being wound down, and we are not claiming that. It does tell you that the analytics suite was not the headline of the deal, and that the acquirer’s public storefront today points at deduction recovery, not seller analytics.

A second dated data point in the same direction: the only ManageByStats extension listed in the Chrome Web Store as of 2026-07-25 is ManageByStats: Plugin , published by Carbon6 Technologies Inc, at version 0.1.0, last updated 2025-05-14, with 36 users and no ratings. Earlier reviews treated the browser extension as a selling point; the current listing is a small, year-old, barely-installed one.

What ManageByStats actually includes

The official knowledge base index (checked 2026-07-25) organises the product into these sections, which is the most reliable feature map available right now: Dashboard, Finances, Statistics, Customers, Catapult, Advertising, Products, Supply Chain, SellerMail, Notifications, Consulting, Settings, and Change Log.

Unpacking the parts that matter for a buying decision:

• Profit & Loss. The official Profit & Loss doc says the tab “gives you a thorough breakdown of P&L for your entire business,” with data grouped into “Weekly, Monthly, Quarterly or Yearly periods” and sortable by date order, profit, orders, refunds, or Amazon payout. Rows expand for more detail. The doc does not enumerate which fee categories are included, so treat the granularity as unverified until you see your own account.
• Catapult is the research group, and it is wider than older reviews suggest. The knowledge base files eight tools under it (nav checked 2026-07-25): Finder (product discovery), MBS Retriever, Keyword Scout, Distiller, Wordsmith, Keywords Tracker, Keyword Performance, and Launch Tracker. This is the part that overlaps with general research suites rather than pure accounting tools.
• Customers, including a customer list, a customer hub, and Repeat Buyers tracking. Repeat-purchase visibility is a useful edge over tools that stop at SKU-level profit, since it answers a question a pure P&L view cannot.
• SellerMail for buyer messaging and review requests. This is the one module with an official, current price attached (see below).
• Change Log is not a product changelog — the official Change Log doc (checked 2026-07-25) says it “can be used to note changes you made to any aspect of your Amazon business,” which are “then flagged on graphs.” In other words it lets you record your own actions so you can line up a sales shift against the thing that caused it. That annotation habit is genuinely useful and rarely built into analytics tools; it is the module we would test first in a trial, and the one here that a spreadsheet does not replace.
• Supply Chain and Notifications round out operations. Depth here is undocumented publicly; if inventory planning is your actual bottleneck, a dedicated forecaster like the one in our SoStocked review — another Carbon6 tool — is the more direct comparison.

Setup: what it asks of your Seller Central account

Worth knowing before you start a trial. The official User Permissions doc states that the ManageByStats user you create inside Amazon Seller Central needs “View & Edit” on Transactions, Brand Analytics, Business Reports/Sales Summary, and Payments. That is broader than read-only reporting access, and the same doc notes you will see a warning inside ManageByStats “if we’ve lost permissions for the ManageByStats user you created in your Amazon Seller Central, or the permissions are incomplete” — i.e. permission drift is common enough to have its own troubleshooting page. Budget a few minutes and know which access you are granting.

On marketplace coverage, the extension’s published manifest declares host permissions for 16 Amazon domains (amazon.com, .co.uk, .ca, .fr, .de, .com.br, .com.mx, .co.jp, .it, .es, .cn, .in, .nl, .se, .sg, .com.au) and no non-Amazon marketplaces, checked 2026-07-25. A 2022 third-party review likewise described the tool as limited to Amazon with no multichannel capability. Both point the same way, but neither is an official 2026 statement about the web app, so confirm during a trial if you sell on Walmart or Shopify.

ManageByStats pricing in 2026: what is verifiable and what is not

The honest answer: only one ManageByStats price is officially verifiable today, and it is not the subscription.

The official SellerMail doc (Activating SellerMail , checked 2026-07-25) states the free option gives “up to 1,000 emails/month free, with an $8 per 1,000 emails overage fee,” and that “using the Amazon Review Request feature in ManageByStats does not add to your total email count.” Higher-volume subscription options exist and the plan can be changed at any time.

For the platform subscription itself, the official pricing page is behind the login wall described above, so every figure below is third-party and dated. They do not agree:

Read the conflict carefully rather than averaging it. The $24.97 entry figure traces back to a 2023-dated review and is repeated by a 2026-dated one; the $59.97 figure appears on an undated aggregator listing. Both may have been correct at different times, or one may be a stale copy. The third-party sources also contradict each other on whether a free tier exists at all — the SourceForge listing indicates a free version is available, while WebRetailer’s facts box records “FREE VERSION: No” (both checked 2026-07-25) — and with the official pricing page unreadable there is no way to settle that from outside, so treat the free tier as unconfirmed until you see it on the signup screen. A 2022 third-party review adds that additional seller accounts cost $10/month each beyond two included accounts, which is the kind of add-on that quietly moves the real bill — the same true-cost problem we break down in our Amazon seller tools pricing comparison .

Practical guidance: do not budget off any number on this page. Start the trial, then read the price on the checkout screen before the card goes in. If a vendor will not show you a price without a login, that is itself a data point about how the renewal conversation will go.

What real users complain about

We read ManageByStats’ public reviews for this article, and the distribution skews positive. The WebRetailer page is a software-directory listing rather than an editorial hands-on test: alongside a short vendor-style product description it carries 29 user-submitted reviews dated between 2016-02-04 and 2021-12-09, of which 25 give a 100% overall rating (counted 2026-07-25), and several of the positive ones name customer support specifically. Note the date range — nothing on that page is newer than 2021. So the themes below are the minority view, not the average experience. They are worth reading anyway, because they are specific, they recur across independent reviewers, and they all land on the same organ: the numbers.

1. Accuracy of the numbers. This is the loudest theme and the most damaging one for an analytics product. A long-term user who benchmarked it against a cheaper competitor wrote:

“I used manage by stats for years, which was ok to start with, but after comparing it to sellerboard recently, I realized that the profit margin stats were wildly out compared to sellerboard and very misleading, I couldn’t believe it, even though i had checked all my settings on both platforms.” — Trustpilot, 2★, 2022-04-13

A 2024 reviewer reported the same class of problem at the dashboard level:

“This company is complete garbage. The dashboard, which used to be pretty decent, is now unintelligible. Their mobile app does not work. And the sales numbers across different marketplaces are dubious.” — Trustpilot, 1★, 2024-09-25

Two more accuracy issues come from one older but unusually specific account — a single user review posted in WebRetailer’s user-review section by a reviewer named Joe, scoring the tool 73% overall, who wrote at the time that they were still a paying user:

“The PPC data is inaccurate and does not give you 100% of the spend for your Products/brands. A big miss in profitability. We have found it be 10-20% off/low. Customer support did not help much except for excuses about why they couldn’t be accurate. […] If you are a multi-channel fulfillment customer MBS will overstate your expense by the cost and FBA fee for these orders, no way for them to exclude. This over reports expense.” — WebRetailer user review , 73% overall, 2020-07-09

Read that with its date attached: it is one reviewer’s account from 2020, the oldest evidence we cite here, and it is not our own measurement. What makes it worth quoting anyway is that it names two mechanisms — advertising spend arriving low, multi-channel fulfillment orders arriving as inflated expense — rather than just saying the numbers feel wrong, and both are exactly the kind of thing you can check against your own Seller Central reports inside a trial.

2. Breadth turning into clutter. The clearest published statement of this is in the 2022 third-party review , which lists as cons “Content overload: The sheer amount of material flying your way can make it so that the user interface gets cluttered, and the title of widgets become hard to read” and “Somewhat advanced: Not ideal for beginners, as it requires at least intermediate selling knowledge” (checked 2026-07-25). The 2024 reviewer above puts the sharpest version of it: a dashboard that got worse in redesign.

3. Billing surprises and cancellation friction. One reviewer was caught by an intro-rate step-up:

“The first-month subscription is 20+ dollars and the second month on its about 4 times.” — Trustpilot, 1★, 2021-07-04

The same reviewer added: “I was asked way too many questions before the final button of cancelling, and my subscription was ended right after I clicked despite the fact that I have just paid $89 for the current month.” Combined with the fact that no price is publicly readable in 2026, this is the theme we would stress-test hardest: know the month-two price and the cancellation mechanics before you subscribe.

All three of these themes rest on evidence that predates the close of the SPS Commerce acquisition on 2025-02-07: the oldest complaint we cite is dated 2020-07-09 and the newest 2024-09-25. None of it is guaranteed to describe the product you would sign up for today. We found no 2026-dated verified user review either confirming or clearing them, which is part of why the pricing opacity matters — there is not much recent public signal to go on.

ManageByStats scorecard

Scored on our 8-dimension seller-tool scorecard , based on official documentation, the Chrome Web Store listing, and public user reviews as of 2026-07-25. This is a desk assessment, not a controlled benchmark or a long-term account.

The shape of that scorecard is consistent: ManageByStats scores on breadth and loses on trust and transparency. For a tool whose entire job is telling you your true numbers, those are the two columns that decide it.

Who it fits, and who should skip it

Consider ManageByStats if you are an established, Amazon-only seller who wants analytics, customer data, research, and buyer messaging behind one login instead of four subscriptions; if repeat-buyer tracking or the business Change Log solves something your current stack cannot; or if you are already inside the Carbon6 ecosystem and consolidation has real value to you.

Skip it if you are a beginner who needs one clean profit number today; a seller whose accounting has to reconcile to the cent (the accuracy complaints target exactly that); selling meaningfully off Amazon; or unwilling to subscribe to a product that will not show you its price before you create an account. If your genuine bottleneck is only the money Amazon owes you rather than analytics breadth, a focused reimbursement auditor is a cheaper route — ReimburseOps runs a free tier that shows the total owed and a severity breakdown but reveals only three records in full, with a flat $19/month Pro tier for full detail, claim-ready exports, and monthly re-scans, and it takes no commission on recoveries (pricing checked 2026-07-25). For the broader landscape, our Amazon reimbursement guide compares the category.

If you decide to leave

This review is about whether ManageByStats is worth your money. If you have already concluded it is not, the replacement depends on which of the three complaint themes drove you out — accuracy, clutter, or price — and we have matched specific tools to each in our ManageByStats alternatives comparison. In short: accuracy-driven switchers tend to land on focused profit dashboards, breadth-driven switchers want fewer modules rather than different ones, and sellers who only used SellerMail can replace that single job far more cheaply — the options are compared in our review and feedback tools hub .

Frequently Asked Questions

Is ManageByStats still active in 2026? Yes. Its knowledge base is publicly online and its Chrome extension listing is live under Carbon6 Technologies Inc (both checked 2026-07-25). What is no longer available is a public marketing or pricing page — those URLs redirect to a Carbon6 login screen.

How much does ManageByStats cost? Not officially confirmable as of 2026-07-25, because the pricing page redirects to a login. Third-party sources report a Starter tier at $24.97/month and Elite at $89.97/month with Enterprise by quote (MerchantSpring, dated 2026-04-06; WebRetailer, last updated 2023-10-23), while an undated SourceForge listing reports a $59.97/month starting price. The one official figure is for SellerMail: 1,000 emails per month free, then $8 per 1,000 emails. Confirm the live price at checkout before subscribing.

Who owns ManageByStats? It is part of Carbon6, which SPS Commerce agreed to acquire for approximately $210 million on 2025-01-02 and completed on 2025-02-07. Neither press release names ManageByStats specifically; both frame the deal around revenue recovery for 1P and 3P suppliers.

Is ManageByStats accurate? That is its most contested area. Independent reviewers have reported profit margins diverging from a competitor (Trustpilot, 2022), questionable cross-marketplace sales figures (Trustpilot, 2024), and PPC spend under-reported by roughly 10–20% alongside multi-channel fulfillment orders inflating expense (a WebRetailer user review dated 2020-07-09). Most public user reviews are positive — 25 of the 29 on WebRetailer’s listing carry a 100% rating, though all 29 predate 2022 — but if your use case is reconciliation, benchmark it against a second source during the free trial before you rely on it.

Does ManageByStats work for multichannel sellers? Its Chrome extension declares host permissions for 16 Amazon marketplaces and no other retailers (checked 2026-07-25), and a 2022 third-party review described it as Amazon-only. We have no official 2026 statement on the web app’s non-Amazon coverage, so verify during a trial if you sell off Amazon.

What is the ManageByStats free trial? Third-party sources consistently report a 14-day free trial, with MerchantSpring (2026-04-06) stating no credit card is needed. Because the official trial terms are behind the login wall, confirm the terms on the signup screen.
