Multi-marketplace store management

One team across every marketplace

Most sellers run each marketplace as its own island — different prices, different stock counts, different logins, different problems. We run them as one business: unified pricing strategy, coordinated inventory, consistent branding, and a single report that shows every channel. Amazon, eBay, Walmart, Etsy, and TikTok Shop as the core five — plus Newegg, Poshmark, and Grailed where they fit your catalog.

What’s included

• Listings & SEO — optimized per marketplace, because what ranks on Amazon doesn’t rank on eBay.
• Pricing strategy & repricing — competitive across channels without margin suicide.
• PPC & promoted listings — Amazon PPC, eBay Promoted Listings, Walmart and TikTok ads, managed to targets.
• Inventory & order-flow coordination — one view of stock across channels. No overselling.
• Review & feedback management — legitimate velocity, handled properly on every platform.
• Performance reporting — weekly, plain English, every channel in one place.

The ZAXIUS framework: Audit → Structure → Operate → Protect

Every engagement runs the same four phases. Audit: we tear down your current operation and find the leaks. Structure: we rebuild listings, pricing, and processes on solid foundations. Operate: we run the day-to-day — that’s the management you’re buying. Protect: account health, brand protection, and compliance, so one policy email doesn’t end the business.

Who full-service management is for

Sellers doing real volume on two or more marketplaces who can’t keep up manually. Brands expanding to new marketplaces without hiring. Founders who’d rather sell than spreadsheet. If you’re still validating your first product, start with our free audit — management pays for itself once the operation is bigger than one person.

What a managed week actually looks like

Management is mostly unglamorous, repeated work done on schedule — which is precisely why it slips when a founder does it between everything else. In a typical week on a managed account: listings are checked against search performance and refreshed where rankings or click-through slip; prices are reviewed against competitors and your margin floor, using the same math as our FBA profit calculator and break-even calculator; ad campaigns are pruned — search terms harvested, wasted spend cut, budget moved toward what converts; stock positions are compared across channels so a bestseller never goes dark on one marketplace while it sits in a warehouse for another; and buyer messages, reviews and account-health notifications are handled before small issues become cases. None of these tasks is individually dramatic. Together, done every week without exception, they are the difference between an operation and a hope.

What we need from you — and what we measure

Your side is deliberately small: one decision-maker we can reach, prompt approval on the handful of calls that are genuinely yours (new products, price floors, budget changes), and honest information about stock, costs and constraints. In return, everything we do is measured against numbers you can see in the weekly report: sales and conversion by channel, advertising efficiency against your targets, listing health, stock coverage and account-health status. We do not report vanity metrics or cherry-picked screenshots — if a channel has a bad week, the report says so, with what we are doing about it. That transparency is the point of the Protect phase as much as the Operate phase.

Mistakes that stall multi-marketplace growth

Three patterns show up in almost every account we take over. Copy-paste listings: the same title and bullets on every marketplace, even though each platform's search and buyers behave differently — eBay rewards specifics Amazon truncates, and TikTok Shop sells socially, not by keyword alone. One price everywhere: fee stacks differ by channel, so a single price quietly loses money on one marketplace while overpricing another. Set-and-forget advertising: campaigns launched once and left running while search terms drift. Our guides to choosing between an Amazon agency and a freelancer and what Amazon account management actually costs explain how to judge any provider — including us — against these failure modes before you commit.

What you keep control of

Your account stays yours. You remain the account owner, you hold the primary login, and you grant us access through the marketplace’s own user-permission system — never by handing over your password, and we will never ask for it. Payments, payout details and tax information stay in your name and under your control, and you can revoke our access at any time. We operate inside your account; we never hold it, or your brand, hostage.

One rule never changes: marketplace accounts are always created in your own name and your own business. ZAXIUS never sells, rents or creates marketplace accounts for transfer — if an account is set up during onboarding, it is set up as yours, under your details, from day one.

Example: how an onboarding runs

Illustrative walkthrough — this example shows the process a new client moves through. It is not a client case study and no results are claimed for it.

• Day 1–2: you grant user-permission access on each live marketplace and share stock, cost and margin data.
• Week 1: one audit across every channel — the copy-paste listings, one-price-everywhere and set-and-forget ads patterns are usually found here.
• Week 2: pricing is rebuilt per channel against each fee stack, and listings are separated so each marketplace gets copy written for its own search.
• Week 3 onwards: one team runs every channel and you get one weekly report covering all of them.
