Looking for a Carbon6 / SPS Revenue Recovery alternative? Here's what to consider.

If you're looking for a Carbon6 alternative, you probably already know what Carbon6 — now operating as SPS Revenue Recovery under SPS Commerce — does. You've likely used it, been pitched on it, or had a finance conversation triggered by it.

This isn't a takedown. Carbon6 / ChargeGuard is a genuinely capable product. The question worth asking isn't "is it good?" — it's "is it solving the right problem for where you are now?"

Here's an honest assessment of what it does well, where it stops, and what the alternative category looks like.

#What Carbon6 / SPS Revenue Recovery is good at

ChargeGuard — now part of SPS Revenue Recovery — is built to recover money Amazon has already taken. It does this thoroughly:

• It audits up to 5 years of Vendor Central history. That's real money sitting unclaimed on brands that have never run a systematic deduction audit.
• It runs on a free audit (the C.E.R.A. — Carbon6 Evaluation & Recovery Assessment) with no upfront cost. You pay 25% of what they recover. If they find nothing, you pay nothing.
• It handles the full dispute workflow — identifying eligible chargebacks, assembling documentation, filing, following up. The Head of Amazon doesn't have to manage it.
• It covers shortage claims, compliance chargebacks, pricing discrepancies, and overbillings across Amazon Vendor Central. Post-acquisition, SPS adds Walmart, Target, Kroger, and more through the SupplyPike product.

For a brand that has never run a systematic deduction audit, or that has 2–3 years of accumulated historical chargebacks, Carbon6 / SPS Revenue Recovery is probably the right first tool. The free audit produces a number. You recover some of it. The ROI is immediate and visible.

#Where it stops

The deduction rate doesn't fall.

This is the pattern that drives most people to look for alternatives. Recovery happens. The commission is paid. Next quarter, the same chargebacks appear. The same ASN accuracy issues, the same shortage claims for the same product lines, the same compliance fines from the same fulfilment centres. Another dispute cycle begins.

This isn't a flaw in Carbon6's execution — it's a structural limit of the recovery model. Disputing a chargeback doesn't tell your warehouse to fix the ASN format. Recovering a shortage claim doesn't change what your 3PL does at the dock. The cause of the deduction lives upstream — in your ERP, your WMS, your carrier handoff. Recovery tools work entirely downstream, in Vendor Central.

Carbon6 does include root cause analysis — it will tell you, after the dispute, that ASN accuracy errors were the cause of these shortage claims. But that analysis is retrospective. It describes what happened. It doesn't close the loop back into operations so it stops happening.

The 25% commission scales with your pain.

At 25% commission on recovered amounts, a brand recovering £400K/year is paying Carbon6 £100K annually. If recovery runs for three years, that's £300K in commission on a problem that isn't shrinking. A brand that genuinely eliminates its deduction sources stops paying that commission — but elimination requires intervening upstream of the deduction, not downstream of it.

The acquisition created complexity.

Carbon6 is now one product among many inside SPS Commerce, a $750M supply chain EDI company. The Carbon6 brand redirects to SPS Commerce. The product naming — ChargeGuard, SPS Revenue Recovery, SupplyPike, Seller Investigators — is in flux. If you're evaluating for a long relationship, the question of which team, product roadmap, and account manager you're actually signing with is worth getting a direct answer on.

#The question recovery tools can't answer

Here's how to test whether you need an alternative.

Ask your current recovery service — or any recovery service you're evaluating — this question:

"What has happened to our deduction rate since we started working with you?"

Not "how much did you recover." The deduction rate: the percentage of your Vendor Central revenue that Amazon deducts, measured over time.

If the rate is flat or rising despite active recovery, the tool is working as designed. For your business. The deductions are being monetised — disputed, partially recovered, commissioned on — but the underlying problem is unchanged. Your P&L shows a recovery line and a deduction line. The deduction line isn't moving.

Recovery tools are optimised to answer "how much can we get back?" Prevention tools are optimised to answer "how do we reduce what Amazon takes?"

Those are different products with different architectures and different incentives. A tool that earns 25% of recovery has no revenue incentive to reduce the deduction volume. A tool built to reduce the deduction rate needs to connect to the systems upstream of the deduction — ERP, WMS, carriers — not just Vendor Central.

#How PACMAN approaches it differently

PACMAN starts from the same place Carbon6 does: every deduction gets investigated, documented, and disputed if it's disputable. The difference is what happens next — and where it looks.

Carbon6 works Vendor Central data. PACMAN works the systems upstream of Vendor Central — ERP, WMS, EDI, carriers — at the same time. That's the whole game. The root cause of a shortage claim (the WMS scan failure, the ASN timing error, the 3PL labelling issue) lives in systems Amazon never sees. Trace it there and you can name the specific operational failure and close the loop back into operations automatically — so the same deduction doesn't reappear next quarter. Carbon6's root cause analysis stops at description, after the dispute. PACMAN's drives prevention, before the flag.

Most recovery tools give you a dispute outcome. We prevent the dispute from being necessary.

Two consequences fall out of that — and both invert Carbon6's incentives:

• Commission. We don't charge on Amazon's own auto-corrections (Smart Match resolved 61–72% of shortage claims within 30 days across our own client set, no dispute filed). We wait for that to settle and bill only on cases PACMAN actually won — not on money Amazon was returning anyway. Carbon6's 25% applies to gross recovery.
• The metric that moves. PACMAN is built to move the deduction rate — the number on the CFO's dashboard — not just the recovery total. Recovery offsets the loss; prevention shrinks it.

This is the recovery-vs-prevention split in miniature. The full argument — why prevention wins as your deduction base scales, and where each major recovery tool sits on that line — is here: recovery vs. prevention, compared across the market.

#Side by side

#Which is right for you

Start with Carbon6 / SPS if:

• You've never run a systematic deduction audit and have years of historical chargebacks sitting unclaimed
• You need fast, no-upfront-cost recovery wins for a finance conversation this quarter
• You need multi-retailer coverage (Walmart, Target, Kroger) alongside Amazon

PACMAN makes more sense if:

• You've been recovering deductions for 12+ months and the rate hasn't moved
• Your CFO is asking why the deduction line isn't shrinking despite active recovery
• The same chargebacks are recurring every quarter from the same root causes
• You want the metric on the board to be deduction rate, not recovery rate
• You're approaching an AVN and need a credible compliance improvement story for Amazon

The honest answer for some brands: do both, in sequence. Clear the historical backlog first. Then fix the compliance layer so the backlog doesn't rebuild.
