Independent Amazon seller reinstatement agency with zero upfront fees

Founded by Michele Corvo, a former Amazon employee, Northline helps sellers keep their accounts in good standing, from reinstatements and appeals to disputes at both the account and ASIN level. We built this service for Amazon sellers who need a clearer approach: no upfront fees, no made-up success rates, and no generic AI-written text that solves nothing.

Priority Route

The priority callback is meant for recent suspensions, repeatedly rejected appeals, or funds under immediate pressure. It only makes sense when delay would genuinely worsen the next move.

About The Case-Review Team

Northline’s case-review team brings together founder Michele Corvo and two independent specialist consultants. All three are former Amazon employees.

At Amazon, he worked on major projects related to Seller account suspensions, particularly during the “Great Crackdown of 2019,” a major turning point when Amazon significantly changed its internal systems for evaluating Seller performance and behavior, with a direct impact on the intensity of controls and the number of suspensions.

The two independent consultants support cases when their relevant specialist experience matches the issue. Case staffing depends on the facts and scope, so not every specialist works on every engagement.

Northline is independent from Amazon. Former Amazon employment is professional background only and does not imply affiliation, endorsement, privileged access, or influence over Amazon’s decisions.

Amazon Section 3 deactivation: what the notice means and what sellers should check first

A Section 3 notice is usually the contractual wrapper for an account deactivation, not the operational root cause. The appeal has to start by identifying the real trigger.

FAQ

Questions sellers usually ask before they submit

In this category, trust comes from clarity. These answers are here to keep the tone and promises realistic.

No. Northline Seller Recovery is an independent consultancy built around former Amazon experience, not an official Amazon service. We do not represent Amazon, we do not control Amazon’s decisions, and we do not claim privileged channels. The value here is diagnosis-first case review: understanding the real issue family, evidence burden, and next route before another weak submission damages the record.

No legitimate service can guarantee reinstatement, because Amazon remains the final decision-maker on accounts, listings, and funds. What can be done is narrower and more useful: classify the notice correctly, review the record already on file, identify evidence gaps, and decide whether the next move should be documents, a cleaner POA, escalation control, or a different route entirely.

For eligible cases, no upfront fee. If we take the case, the commercial trigger is defined in writing before work begins. Funds-on-hold matters are billed only after the agreed result is achieved. If the case is outside scope or the fit is weak, that should be made clear early rather than wasting time and money on a generic engagement.

It does not mean a vague promise. It means the commercial success trigger has to be defined in writing before work starts. Depending on the case, that may be account reinstatement, listing restoration, a held-funds milestone, or another clearly agreed outcome. If the case is still too mixed to define success honestly, the first step should be diagnosis, not a loose commercial promise.

Yes, but held funds are not one single case type. Sometimes the real issue is reserve pressure, negative balance, bank verification, reimbursement-claims behavior, or fallout from a wider suspension. The first job is to separate the economic pain from the real root cause. If Amazon is holding payouts, send the notice history, payments timeline, and anything already submitted before treating it like a generic funds appeal.

The fastest first pass usually needs three things: the latest Amazon notice, a short factual timeline of what happened, and a clear list of what has already been sent to Amazon. If the case involves documents, include the current document set or explain what is missing. If it involves funds, account linkage, or repeated rejections, include that context early so the next route can be judged properly.

Yes. A rejected appeal does not automatically mean the case is over, but it does mean the next move has to be cleaner than the last one. The first job is usually to review what Amazon already saw, identify contradictions or missing proof, and decide whether the real problem is weak evidence, wrong classification, or a submission path that never matched the live issue.

No. Good Amazon recoveries rarely come from reusable templates alone, because verification, related-accounts, authenticity, review-manipulation, and performance cases do not fail for the same reason. A useful submission follows the live notice, the real root cause, the evidence already on file, and the route Amazon is actually using. Template language is often what makes a recoverable case look weaker.

Use the Priority Route only when timing pressure is real: a recent suspension, repeated rejected appeals, funds under immediate pressure, stranded inventory, or a warning-stage case that could harden quickly. If the case is important but not genuinely time-sensitive, standard intake is usually safer because it leaves more room to classify the issue cleanly before another rushed upload or appeal.

Use the homepage when the case is still mixed or the notice language is not clear enough to classify confidently. Use a case-type page when the category is already visible—for example related accounts, inauthenticity, identity verification, review manipulation, or a performance metric. The goal is to avoid answering the wrong problem with the wrong documents.

Yes, provided the operating structure and who controls the Amazon accounts can be explained clearly. Multi-account, agency-managed, aggregator, and group-level setups often create harder linkage, access, and document-governance questions than simple single-seller cases. That is exactly why the file needs clean ownership, operator history, and prior-submission context from the start.
Ready for Review

Send the Amazon notice, get a human review, and understand the next step.

Use this form when the issue is unclear or crosses several categories. If Amazon's notice names a specific issue, open the matching case page first. Use the priority callback only when delay creates additional risk.
