What Our Clients Say
JSA helped us step back and really understand what was happening across our Amazon business. They showed us where we were leaving opportunities on the table and gave us a clear, practical plan for improving performance and profitability.
What I appreciate about JSA is that they don't look at advertising or operations in isolation. They helped us see how everything fits together and gave us a much clearer direction for growing the brand profitably on Amazon.
Running an Amazon business can become overwhelming, but JSA helped us make sense of it. They clarified what we needed to focus on, helped us strengthen our processes, and made us feel much more confident about our decisions.
What Results Look Like With JSA
Results from brands JSA manages on Amazon. Measured from account data, with the measurement period stated on every study.
Grew sales while cutting TACoS 27.6% in two months
Challenge
A healthy Amazon business with room to improve sales efficiency. The goal was simple: grow without letting ad spend eat into margins.
Approach
JSA took over the account in June 2026 and audited the advertising account to find where spend could work harder. We focused on campaign efficiency and shifted spend toward the traffic and opportunities driving the strongest results.
Results
Results measured over June to August 2026 compared with March to May 2026. TACoS reduction measured after two months of management. Individual results vary based on account conditions.
Get Similar ResultsAd sales up 74.8% with ACOS down eight points
Challenge
The brand needed full Amazon coverage without building an internal team to run it. Ad spend was working against a 29.9% ACOS, and advertising, catalog, inventory, and reporting were all competing for attention nobody had.
Approach
JSA has managed the account for two years: advertising, catalog, reporting, inventory planning, promotions, and day-to-day operations. The opening audit set the priorities. Everything since has been scaling what proved out and cutting what didn't.
Results
Results measured over the most recent 15 months (June 2025 to August 2026) against the prior 15 months, which includes one additional Prime Day event. Individual results vary based on account conditions.
Get Similar Results$110,000 recovered from an unapproved co-op rate
Challenge
Amazon raised the brand's co-op rate without approval. The higher allowance came off every remittance from that point on, quietly eating margin nobody had agreed to give up.
Approach
JSA reconciled the deductions against the signed vendor agreement, found the rate Amazon was applying didn't match the rate the brand had approved, and disputed the difference with the agreement as evidence. Every remittance was checked against contracted terms for the rest of the engagement.
Results
Individual results vary based on account conditions.
Get Similar ResultsThe questions we get on every first call.
A real read of your account, not a template. We look at advertising efficiency, listing indexing, account health, inventory position and, for vendors, deductions and chargebacks. You get the findings ranked by dollar impact, with the numbers behind each one. You keep the findings either way.
Advertising waste comes down in the first two to three weeks because negations and bid changes take effect immediately. Organic rank moves on a slower clock, usually six to twelve weeks depending on category. Deduction recovery depends on Amazon's dispute timelines, which we don't control.
Both, and the work differs. Vendor accounts turn on deductions, co-op terms and purchase orders. Seller accounts turn on Buy Box, fees and inventory. We audit for whichever you actually run, or both if you're hybrid.
User access to your Seller or Vendor account and your ads console, read-only to begin. That's enough for the audit. Nothing changes in the account until you've seen the findings and approved a plan.
No. We work month to month with no lock-ins and no exit fees. Clients stay because the reporting shows the work is paying for itself.
