Carbon6 Review (2026)
The best operations tools remove repetitive work quietly — the win is fewer dropped balls and less manual oversight, not more dashboards. So where does Carbon6 actually fit?

What Carbon6 does
SPS Commerce Revenue Recovery — the toolset formerly sold as Carbon6, acquired by SPS Commerce on 7 Feb 2025 and folded into spscommerce.com. Recovers retailer deductions, chargebacks and shortages for 1P suppliers across Amazon, Walmart, Target and Kroger, alongside SoStocked, ScanUnlimited and SPS Ad Performance (formerly PixelMe). Note: the 3P Amazon FBA reimbursement arm was divested on 30 Jun 2026 to an undisclosed buyer.
Pricing (2026)
What we can verify on the vendor's own pages today (checked 21 Jul 2026): SoStocked lists ProfitFlow at $97/mo and ProfitFlow + Inventory at "starting at" $250/mo; ScanUnlimited lists a free Limited tier, Unlimited at $720/yr and Unlimited Plus at $1,080/yr. SPS Ad Performance (the former PixelMe) publishes no price at all — it is contact-sales only. The 3P FBA-reimbursement service publishes no commission rate on its page; it is sold as a contingency arrangement (vendor claim: you pay only on money actually recovered, with the fee reversed if Amazon claws a reimbursement back), and since that business changed hands on 30 Jun 2026 we cannot verify who sets the rate now. We therefore quote no reimbursement percentage. Our previous figures — entry tools from about $49/mo, PixelMe from about $500/mo with a 6-month minimum, about 25% of recovered, and $300-500+/mo for a working stack — are withdrawn: none of them is verifiable against a live authoritative source today. Plans change — always verify the live price on their site.
The honest knock
The honest headline is no longer pricing — it's ownership. This is not a standalone vendor: SPS Commerce bought Carbon6 for roughly $210M on 7 Feb 2025 and retired the brand into spscommerce.com. Then on 30 Jun 2026 SPS announced it had sold the entire 3P (Amazon marketplace seller) revenue-recovery business for $9.5M cash, booking an estimated $20M loss, and did not name the buyer. Read those two numbers carefully, because they are not the same thing: the $210M bought the whole Carbon6 stack, while the $9.5M was the 3P arm on its own. Even so, offloading that arm at a book loss seventeen months in tells you how it performed — and it is precisely the piece we previously told you to start with. Sign-up flows still route through login.carbon6.io and the SoStocked page still links to a Carbon6 notice, so the plumbing is mid-migration. Compounding it: Reuters reported on 23 Jun 2026 that SPS itself hired Morgan Stanley to explore a sale under activist pressure, talks early and no deal assured. Buy the 1P deduction-recovery work on its merits — SPS kept it and is investing in it. For 3P reimbursements, wait until you can name the counterparty on your contract.
What buyers report about Carbon6
Recurring themes from G2, Capterra and Amazon-seller comparisons, read in August 2026. We have not run Carbon6 ourselves, so this is other buyers' experience rather than ours. We summarise it here because the complaints are usually the part a vendor page leaves out.
- • It consolidates tools sellers otherwise buy separately — SoStocked, PixelMe, ManageByStats and others under one roof. Around 4.3 on G2 across roughly 23 reviews.
- • SPS Commerce acquired it for $210M in February 2025, so there is real corporate backing behind it.
- • The FBA reimbursement commission is 25%, against 18% at Refully and 10% at TrueOps. On recovered money that difference is large.
- • Amazon's 31 March 2025 policy change moved reimbursements from sale price to manufacturing cost, which shrinks what any provider can recover. The case for this category is weaker than it was in 2024.
- • Pricing is confusing across the suite — several tools, several tiers, no clean total.
- • The acquisition fragmented the brand: carbon6.io redirects to spscommerce.com and pricing became more opaque.
- • The ad tools are decent but not as deep as Perpetua or Pacvue.
When the paid plan is worth it
Carbon6 is not one subscription, so there is no single premium tier to weigh. The only tool in the suite with a real free-versus-paid decision is ScanUnlimited. Its free Limited plan is capped at one file upload per month and 10,000 products per upload, and that cap is what bites first: a supplier catalogue often runs past 10,000 lines, and once you have spent your single upload you cannot re-scan the same list when the supplier reprices. If you evaluate one modest list a month, stay on free. If you work several suppliers, or re-scan as costs move, Unlimited ($60 a month on the annual plan, $720 a year) lifts you to unlimited uploads and 100,000 products per file; Unlimited Plus, at $1,080 a year, adds course access and daily picks, not scan capacity. What upgrading does not fix: you are still buying one tool. SoStocked is billed separately, from $97 a month for ProfitFlow and from $250 a month once inventory forecasting is included, and the advertising tools price separately again: PixelMe from $500 a month plus a $500 onboarding fee, PPC Entourage at 2.9% of connected ad spend. Paying for ScanUnlimited buys scan volume, not the suite.
How to actually use Carbon6
The shortest route to a usable result runs through ScanUnlimited. Create an account, connect an Amazon marketplace under Settings and the Amazon Credentials tab, then click New Scan and upload a supplier list. You choose the product identifier type (UPC, EAN, ASIN, ISBN or keyword), map the identifier and cost columns, pick a marketplace, and the scan returns matched listings. Distilled from ScanUnlimited help-centre articles (Adding Your First Amazon Marketplace, Upload a File, How to Format a File), the ScanUnlimited pricing page, the SPS Commerce product pages for ScanUnlimited and SoStocked, and the Carbon6 product pages for PixelMe and PPC Entourage
Common Carbon6 setup mistakes
Where Carbon6 setups actually go wrong, and what it costs you when they do. Same sources as the setup notes above — not from a walkthrough we ran ourselves.
Where it goes wrong is the file and the connection.
- Only CSV, XLS and XLSX are accepted, and in a workbook only the first sheet is read, so a hidden or second sheet quietly produces the wrong scan.
- Cost values must be in US number format.
- Long product IDs saved to CSV from a spreadsheet turn into scientific notation and stop matching.
- Keyword scans are capped at 10,000 lines, and a scan can display 8 custom columns.
- On the connection side, a newly created seller account can show as invalid; the documentation says to wait 24 hours before resubmitting, and it still walks you through the retired MWS token flow rather than the current API.
The natural comparison is Helium 10 or GETIDA — Helium 10 is the flat-priced seller suite with published tiers; GETIDA is the independent FBA-reimbursement specialist — against a business that has changed hands twice in eighteen months, both win on the plain fact that you know who you are contracting with. Decide by which one fits the job above, not by the louder brand.
My ex-banker filter is simple: does Carbon6 remove a real cost — time, errors, missed revenue — bigger than what it charges? If the job above is genuinely yours, it's worth a look. We never publish fake or “exclusive” prices, so always confirm the current plan on their site.
Frequently asked questions
Does Carbon6 replace my current setup or sit on top of it?
Usually it sits on top rather than replacing everything. Tools in this class tend to become the layer where work is tracked and handed off, while your existing systems stay the source of truth for their own data. Before you buy, map which tools it would replace outright and which it would merely sync with. If the answer is that it syncs with all of them, you are adding a layer rather than removing one.
Who should not use Carbon6?
Skip it if your job is 3P Amazon FBA reimbursements — that arm was sold on 30 Jun 2026 to an undisclosed buyer, so you cannot yet name who holds your contract, your Seller Central access or your fee. Buying a tool to fix a problem you don't have yet just adds cost and another login to manage.
