Carbon6 Reviews — Pricing, Features & The Honest Take

Carbon6 is a portfolio of eight Amazon-seller tools, and this listing’s link goes to exactly one of them: ScanUnlimited, a wholesale sourcing scanner. It is worth knowing that before you click, because “Carbon6” and “a tool for scanning wholesale price lists” are very different purchases. On its own terms ScanUnlimited is good value — the free plan never expires, and the paid plan is $60 a month billed annually. The one number that does not survive checking is the “2 months free!” on annual billing, which is really 1.7 months.

• What it is: A wholesale product-sourcing scanner for Amazon sellers, part of the Carbon6 group.
• Best for: Amazon wholesale sellers screening supplier price lists.
• Pricing: Free forever, or $60/month billed annually ($70 monthly). Verified August 2026.
• The honest catch: The link is one product, not the Carbon6 suite.

What Is Carbon6 — and What Does This Link Actually Give You?

Carbon6 is a group of software products for Amazon FBA sellers. Its site lists eight, each branded “by Carbon6”:

• Seller Investigators — FBA reimbursement recovery
• PixelMe — off-Amazon advertising and external traffic
• DSP Prime — Amazon DSP campaign management
• PPC Entourage — Amazon PPC optimisation
• SoStocked — inventory and demand planning
• ScanUnlimited — wholesale product sourcing
• D8aDriven — AI-powered operational insights
• ManageByStats — profit analytics

The affiliate link on this listing resolves to ScanUnlimited, so that is the product reviewed here. It scans wholesale supplier price lists against Amazon data to find products worth buying: “Quickly scan wholesale product lists to find profitable, fast-selling products on Amazon.” ScanUnlimited reports over 20,000 Amazon sellers using it.

It requires an Amazon Professional Seller account, because it uses your MWS credentials to query Amazon’s products API.

A note on the listing: this product is currently described on Findstack as a platform “integrating tools for CRM, project management, team collaboration” — which describes neither Carbon6 nor ScanUnlimited. Carbon6 is Amazon seller software. This review covers what the link actually delivers.

How ScanUnlimited Works

• Upload a supplier price list, it scans against Amazon data.
• 300,000+ products an hour scan speed on both plans.
• Free plan is permanent — one file upload a month.
• Paid plan is $60/month billed annually, $70 monthly.
• Requires an Amazon Professional Seller account.
• Downgrade to free at any time, effective at cycle end.

ScanUnlimited Pricing

What actually decides your cost:

• “2 months free” on the annual plan is really 1.7 months. Two months free on a twelve-month term means paying for ten: 10 × $70 = $700, or $58.33 a month. ScanUnlimited sells the annual plan at $60 a month, which is $720 a year — a $120 saving against monthly billing, or 14.3%. That is a genuine discount worth taking, just $20 short of the claim attached to it. Small, but it is the kind of number this review series checks every time.
• The free plan is a real product, not a trial, and the company says so. Asked “Do you offer a free trial?” the FAQ answers: “The free plan is essentially a perpetual free trial.” One file upload a month, up to 10,000 products, at the same 300,000+ products an hour as the paid plan, with product detail access, automatic backups and the Power-Up feature. For a seller evaluating one supplier list a month, that may be the whole requirement indefinitely.
• The paid plan buys volume and one data feature, not speed. Scan speed is identical on both tiers. What $60 a month adds is unlimited uploads, 100,000 products per file instead of 10,000, and Keepa charts with Sales Rank History rather than basic charts. Sales rank history is the substantive one — it is what tells you whether a product actually sells rather than merely existing at a good price.
• Ten thousand products per file is the constraint that will bite first. Wholesale price lists routinely run longer than that. If your suppliers send 30,000-line catalogues, the free plan cannot process one in a single pass regardless of how many months you wait, which pushes you to paid for reasons of file size rather than frequency.
• You can downgrade at any time without penalty. “Once you sign up for a paid plan, you are allowed to choose the Free plan at anytime and your account will automatically downgrade to Free at the end of your billing cycle.” Combined with a permanent free tier, that makes seasonal use practical — pay during heavy sourcing periods, drop back when you are not buying.
• An Amazon Professional Seller account is mandatory. ScanUnlimited works through your MWS credentials against Amazon’s products API. If you are not already paying Amazon’s $39.99-a-month professional tier, that is a prerequisite cost, not an optional one.
• This is one tool, not the Carbon6 suite. The other seven Carbon6 products — reimbursements, PPC, DSP, inventory forecasting, analytics — are separate purchases with separate pricing. Nothing here grants access to them.
• The affiliate link tracks correctly. /go/carbon6 returns 200, resolves through PartnerStack to scanunlimited.com with the partner key intact, and sets the full PartnerStack cookie set (growSumoPartnerKey, ps_partner_key, ps_xid, psuid).

Who Should Use ScanUnlimited

• Amazon wholesale sellers. Screening supplier lists is the entire product.
• Occasional sourcers. The free plan handles one list a month permanently.
• Sellers with large supplier catalogues. 100,000 products per file on the paid tier.
• Seasonal buyers. Downgrade to free between sourcing pushes.

It fits poorly for private-label or arbitrage sellers, who are not scanning wholesale price lists; for anyone without a Professional Seller account, which is a prerequisite; and for buyers expecting the wider Carbon6 toolset, which this does not include.

Honest Pros and Cons

Strengths

• A permanent free plan, described as such by the vendor.
• Same scan speed on free and paid — no artificial throttling.
• Downgrade any time, effective at cycle end.
• 100,000 products per file on the paid tier.
• Keepa charts with sales rank history where it matters.
• No credit card required to start.

Limitations

• “2 months free” is really 1.7 months.
• Free tier caps files at 10,000 products, below many catalogues.
• Requires a paid Amazon Professional Seller account.
• One product, not the Carbon6 suite.
• The Findstack listing describes a different kind of product entirely.
• No mid-tier between free and $60 a month.

ScanUnlimited Alternatives and How It Compares

• Jungle Scout covers product research more broadly, including private label.
• Helium 10 is the largest all-in-one Amazon seller suite, at a higher price.
• Tactical Arbitrage targets the same wholesale and arbitrage scanning niche.
• The other seven Carbon6 tools solve adjacent problems and are bought separately.

The Verdict

Judged as what the link actually delivers — ScanUnlimited, not the Carbon6 portfolio — this is a well-structured product with honest tiering and one small overstatement.

The free plan deserves the credit. It is permanent, the vendor calls it “essentially a perpetual free trial”, and it runs at the same 300,000-products-an-hour scan speed as the paid tier. There is no throttling to make free feel broken, which is the usual pattern. One upload a month at up to 10,000 products is genuinely enough for a seller evaluating a single supplier list, and you can stay there indefinitely.

The $60-a-month Unlimited plan buys three things: unlimited uploads, 100,000 products per file, and Keepa charts with sales rank history. That last one is the real upgrade — price data without rank history tells you what something costs, not whether it sells. For anyone sourcing seriously, that is the reason to pay rather than the upload limit.

The “2 months free!” on annual billing does not quite hold. Two free months on a twelve-month term implies $58.33 a month; the plan is sold at $60, which is $720 a year against $840 monthly — a real 14.3% saving, but 1.7 months rather than 2. Take the annual plan anyway; just do not expect the twentieth-of-a-year the label promises.

Two things to settle before buying. You need an Amazon Professional Seller account for it to work at all, since it queries Amazon through your MWS credentials. And be clear that this is one of eight Carbon6 products — reimbursements, PPC, DSP, inventory forecasting and analytics are all separate purchases. If you came looking for the suite, this link is not it.

FAQ

How much does ScanUnlimited cost?

There is a permanent free plan at $0, allowing one file upload a month of up to 10,000 products. The paid Unlimited plan is $70 a month billed monthly, or $60 a month billed annually — $720 a year. No credit card is required to start on the free plan, and you can downgrade back to it at any time, taking effect at the end of your billing cycle.

Is ScanUnlimited’s “2 months free” annual discount accurate?

Not quite. Two months free on a twelve-month term would mean paying for ten months — $700 a year, or $58.33 a month. The annual plan is sold at $60 a month, $720 a year. Against $840 for monthly billing that is a $120 saving, or 14.3% — equivalent to 1.7 months free rather than 2. The discount is real and worth taking; the label is about $20 optimistic.

Is the ScanUnlimited free plan actually usable?

Yes, and permanently. It allows one file upload a month of up to 10,000 products, at the same 300,000+ products-an-hour scan speed as the paid plan, with product detail access, automatic backups and the Power-Up feature. The company describes it as “essentially a perpetual free trial.” The limitations that will push you to pay are file size and frequency, not throttled performance.

What do I get for $60 a month that the free plan does not include?

Three things: unlimited file uploads instead of one a month, 100,000 products per file instead of 10,000, and Keepa charts with Sales Rank History instead of basic charts. The sales rank history is the meaningful upgrade — it distinguishes products that genuinely sell from products that merely look cheap.

Is Carbon6 the same thing as ScanUnlimited?

No. Carbon6 is a group of eight Amazon-seller products — Seller Investigators, PixelMe, DSP Prime, PPC Entourage, SoStocked, ScanUnlimited, D8aDriven and ManageByStats. ScanUnlimited is one of them, covering wholesale product sourcing, and is where this listing’s link leads. Buying it grants no access to the other seven, which are priced separately.
