Karos Labs is a hands-on operations agency for e-commerce sellers. We do not sell software, and we do not hand your store to an automated tool. A real account manager logs in, audits your dashboards, and fixes what needs fixing, every single day.
Our team builds and repairs listings, defends account health, tracks inventory against real sales velocity, and runs advertising in step with your stock. Every task happens inside your account, done by a person who checks the work, not a script left running unattended.
We build new listings, structure parent-child variations correctly, and clear the problems that hide your products: suppressed listings, stranded inventory, and broken detail pages.
We audit your account health daily, respond to policy violations, file and track IP disputes, and log cases directly with marketplace support until they close.
We track sales velocity, forecast demand to prevent stockouts and long-term storage fees, and create inbound shipments so stock arrives before you run dry.
We manage sponsored ad campaigns and run promotions, holding ad spend in line with the stock you actually have, so you never pay to advertise a product about to sell out.
We own the day-to-day: account health, support case logs, and the small fires that eat your week. Operational stress stops being yours to carry.
Precise inventory forecasting keeps you in stock and out of fee territory, and keeps PPC spend matched to what you can actually sell. Your profit margin stays intact.
A straightforward weekly report breaks down true net sales, margin at the item level, and conversion rates. No vanity metrics, just the numbers you run the business on.
Our expertise is practical. It comes from running real e-commerce accounts every day, intensive self-study of how the marketplace actually behaves, and direct mentorship from established e-commerce operators.
We do not hold formal institutional certifications, and we do not pretend a certificate is what fixes a suppressed listing or a stuck shipment. What fixes those is a person who has done it before, doing it again, by hand, inside your account. That is what we sell: execution you can point to.
We operate to strict data-protection standards. Access to your account is controlled, limited to the people doing the work, and never shared outside the team.
Every credential we hold meets a 12-character minimum.
MFA is enforced on every account with access to your store.
People reach only the systems their role requires, nothing more.
Credentials live in encrypted vaults, never in plain text or shared documents.
We never share your data with outside parties.
The following is a representative example of how we work, not a specific client account.
A brand came to us with a catalog in disarray: detail pages suppressed, listings stranded, and a recurring stockout loop. The previous setup leaned on automated software nobody was watching, and the errors had been compounding for months.
Our team took over daily account audits by hand. We cleared the backlog of open support cases, rebuilt the parent-child variation structure so products were findable again, and synced PPC spend to live inventory run-rates so ad budget followed real stock.
The account stabilized. Suppressions cleared, the case log stayed short, and advertising stopped burning budget on products that were about to run out. The owner got a daily operational arm and a weekly view of true margin.
