SupplyPike or Carbon6 for 1P? One Owner Now

If you searched "SupplyPike alternative" or "Carbon6 alternative," you probably noticed the top results are software directories comparing ERP and inventory tools. None of them answer the actual question: what are the real options for an Amazon 1P vendor who wants deductions recovered? This page does.

First, the fact that changes the comparison

SupplyPike, Carbon6, and ChargeGuard are no longer three independent vendors. All three now sit inside one company: SPS Commerce.

• SPS Commerce acquired SupplyPike effective July 31, 2024, for a total consideration of $205.8 million net of cash acquired.
• SPS Commerce then completed its acquisition of Carbon6 in early 2025, for approximately $210 million.
• ChargeGuard was already a Carbon6 product. Carbon6 acquired it in 2023 to add 1P recovery to its portfolio, and SPS now lists it on its customer sign-in page as 1P Rev Recovery, formerly ChargeGuard.

So if you are evaluating "SupplyPike vs Carbon6 vs ChargeGuard," you are comparing product lines within one owner, not competing firms. That is not automatically bad. Consolidation can mean more investment and better retailer coverage. But it does mean the market has fewer genuinely independent options than the brand names suggest, and it explains why so many vendors are searching for alternatives right now: pricing, packaging, and account teams change after roll-ups, and buyers want a second option before renewal.

Where the absorption stands as of August 2026. The three brand names are disappearing rather than being defended: SPS's own Revenue Recovery product page and its Amazon-deductions content hub no longer mention SupplyPike, Carbon6, or ChargeGuard at all, and SPS completed the sale of the 3P Amazon recovery business it picked up in the roll-up on June 30, 2026. The content migration is also visibly mid-flight: the same educational articles are currently live on two or three different domains (the legacy SupplierWiki and help sites alongside spscommerce.com), some redirected, some not. If you bought from any of these brands on the strength of their name, the thing you bought is being renamed, repackaged, and in the 3P case already sold, which is exactly when contract terms and account teams tend to change.

What each product actually does well

An honest comparison starts with credit where it is due.

SupplyPike

SupplyPike built its reputation as invoice-deduction software: it monitors remittance data, identifies invalid deductions, and automates dispute filing, with reporting that helps you fix root causes. Its SupplierWiki content is some of the best free education in the category, including the definitive write-ups on Amazon's roughly 2-year dispute window for shortage and price claims. That write-up is explicit that "any claims or re-disputes for invoices older than two years are now automatically rejected by the dispute management system," and that "the two-year time limit is according to the invoice date itself." Historically strongest in Walmart supplier recovery, with Amazon coverage added alongside. If you have in-house staff who will work the disputes and you want software to find and file them, it is a credible pick.

Carbon6

Carbon6 assembled a broad toolkit for Amazon sellers on both sides of the platform: 3P reimbursement recovery, plus 1P deduction management through ChargeGuard. Breadth was the strength. A brand running both Vendor Central and Seller Central could consolidate recovery streams with one provider, and Carbon6's blog is a consistently useful reference on chargeback types and policy changes. That both-sides breadth has now split: SPS sold the 3P Amazon recovery business on June 30, 2026, so the 1P and 3P halves of the old Carbon6 offer sit with different owners. Verify who holds your contract before renewal.

ChargeGuard

ChargeGuard is the 1P-specific offer: connect your Vendor Central account, get a free recovery audit, and pay nothing until refunds land. Published third-party reviews describe a 25% commission on recovered funds. Contingency pricing with no upfront cost is genuinely vendor-friendly: the provider only earns when you do. For a vendor who wants disputes handled entirely hands-off, this model works.

The differences that actually matter

Strip away the branding and there are three real decision axes.

Software-first vs service-first. SupplyPike was built as software your team operates. Its current home, SPS Revenue Recovery, calls the product "deduction management software," says "Dedicated retailer specialists add expert guidance on top," and leads with "A free, no-obligation audit." ChargeGuard sells an outcome a team delivers. The middle path, a consultant who runs the recovery process and fixes the upstream causes, is what the pure tools do not do: renegotiating allowance terms, correcting EDI and ASN processes so deductions stop accruing, and building evidence capture into your shipping workflow. Recovery without prevention is a subscription to your own problem.

Pricing model. Software suits vendors with steady deduction volume and a team that will work the queue; a service suits accounts where nobody owns the queue, the backlog is aged, or the claims need judgment a rule cannot apply. Published contingency rates in this category cluster around 25 to 30% of recovered amounts. Neither is wrong; the math depends on your deduction volume, win rates, and internal capacity. What you should not accept is paying a full contingency rate on deductions that a process fix would have eliminated.

Who owns prevention. Deductions are not small, though every published rate for what they cost a typical vendor traces back to recovery-provider marketing, so the only reliable number is the one in your own remittance data. A recovery-only engagement claws some of that back every quarter, forever. A prevention-led engagement makes the number shrink. Ask any provider what percentage of their client base sees deduction rates fall year over year; the answer tells you which business they are really in.

How to evaluate a 1P deduction-recovery partner: 7 questions

Use this checklist with any provider, including us.

1. Is Amazon 1P their core competence? Walmart-first tools bolt Amazon on. Ask how they handle Vendor Central Dispute Management specifics: item-level claim filing (Amazon has restricted the settlement route that bundled many shortages into one case), the roughly 2-year hard window for shortage and price claims, and the 30-day chargeback dispute window.
2. Recovery, prevention, or both? Ask for the split of their work. If 100% is dispute filing, budget separately for fixing root causes.
3. What is the all-in cost model? SaaS fee, contingency percentage (published rates cluster around 25 to 30%), or fixed fee. Model it against your trailing 12 months of deductions before signing.
4. Who does the work? Software you operate, their analysts, or a hybrid. Match it to your team's real capacity, not the capacity you wish you had.
5. What evidence do they need from you? Practitioners point to signed PODs, BOLs, and ASN transmission logs indexed to POs as the records that win disputes. A provider who never asks about your evidence capture will plateau at the easy wins.
6. What happens at contract end? Do you keep the dispute history, the reporting, and the documented process? Or does the capability leave with the vendor? Ask where that history lives, too. Amazon's Data Protection Policy for Selling Partner API solution providers, effective November 25, 2025, bars them from storing non-PII data for longer than 18 months unless the law requires longer retention, so ask whether a provider's history comes from Amazon's API, where that limit applies, or from Vendor Central exports you keep yourself.
7. Are they independent of your EDI provider? Post-consolidation, your EDI network, your recovery software, and your recovery service may all be one company. Decide whether that concentration helps or worries you.

Where a service-first partner fits

Tahiti North is not a software platform, and we do not pretend to be one. We are the service-first alternative: a margin recovery engagement that audits all deduction streams (chargebacks, shortage and price claims, co-op and freight allowances), files and escalates disputes with audit-ready evidence, and then fixes the upstream processes so the deduction rate falls instead of recurring. The dispute-quality gap is the whole game: recovery providers report that an incomplete package can lose on the paperwork before anyone weighs the merits. You can see the full offer on our services page, or go straight to the deduction recovery service.

If you are comparing SupplyPike, Carbon6, and ChargeGuard, add one more data point to the spreadsheet: a free deduction scan of your own account. We review your remittance data, size the recoverable pool across the streams your exports cover, and show you the number before you commit to anyone, us included.
