Built by an Amazon seller
We built OmniSeller to run our own Amazon accounts. Seller Central told us what sold. It never told us what we kept.

Orders, fees, ads and inventory live in different reports, one account at a time. OmniSeller started as our in-house system for pulling them together. Now we are opening it to other sellers who want the same clarity.

What it does

Everything you need to run a profitable Amazon business

OmniSeller turns raw Amazon data into clear operational and financial insight, so you decide on real profit instead of guesswork.

PROFIT

True net profit

Combines orders, Amazon fees, ad spend and product costs into one accurate net-profit figure per product and per period.

Net profit · margin · ROI per ASIN
FEES

Fee transparency

Breaks down every Amazon charge, from FBA fulfillment and referral to storage and refunds, so nothing erodes margin unnoticed.

Referral · FBA · storage · refunds
ADS

Advertising performance

Reads Amazon Ads metrics and ties them back to product-level profit, so you see which campaigns actually make money.

Spend · ad sales · ACOS · TACOS
INVENTORY

Inventory health

Tracks FBA stock levels and storage costs to help you avoid stockouts and aged-inventory fees.

Units on hand · days of cover · storage cost
REPORTING

Daily & intraday reporting

Refreshes sales and advertising data throughout the day, so you always see current performance.

Hourly ad data · scheduled reports
PORTFOLIO

Multi-brand management

Run several Amazon brands and marketplaces from one workspace, with team seats for the people who help you.

Brands · marketplaces · team KPIs
One workspace

Every brand, one view

Built with Claude

Built in house with Claude, by a seller who needed it

OmniSeller is engineered with Claude. We used Claude to build every layer, from the connections to Amazon’s APIs to the dashboards sellers use each day. That lets a small, seller-led team ship like a full product team.

In development PPC optimization & automation and an A+ Content & listing editor, also being built with Claude.

  1. Connect

    Amazon API integration

    Connections to the Amazon Selling Partner API and Amazon Ads API, built and maintained with Claude. They bring orders, fees, inventory and campaign reports into OmniSeller.

  2. Measure

    Performance dashboard

    Net profit, fees, TACOS and inventory health by brand, ASIN and period, designed and coded with Claude.

  3. Decide

    Ads data for better decisions

    Spend, ad sales and ACOS tied back to product profit, so sellers can see which campaigns to scale, fix or pause.

OmniSeller AI · Powered by Claude

Your numbers, explained in plain words

We are building AI features on Claude that read your OmniSeller data and tell you what changed, why, and what to do next. They are in development and will roll out to early-access sellers first.

Daily performance brief

In development

Each morning, a short summary of yesterday: profit, the brands and ASINs that moved, and the reason behind each change.

Brief · exampleYesterday: $3,412 revenue, $812 net profit (23.8%). Brand B margin fell 4 pts because monthly FBA storage fees posted. Brand A ad sales rose 18% at a steady ACOS.

Ask your shop data

In development

Ask a question in your own words and get an answer from your own orders, fees, ads and inventory.

You · exampleWhich ASINs lost money this month?OmniSeller3 ASINs are negative after fees and ads. The largest is B0C7K2M9QX at −$214, driven by a 61% ACOS.

Ad optimization suggestions

In development

Campaigns and keywords to scale, trim or pause, judged on real product profit instead of ACOS alone.

Suggestion · examplePause keyword “garden kneeler pad” (exact): $96 spend, 0 orders in 14 days. Raise bid 15% on “kneeling cushion”: ACOS 18% on a 34% margin product.

Anomaly alerts

In development

A heads-up when something breaks pattern: a fee jump, a stockout coming, ACOS spiking or profit dropping suddenly.

Alert · exampleBrand C · Amazon.ca: FBA fee per unit rose from $4.12 to $5.38 on 2 ASINs. Check package dimensions for a size-tier change.

Examples are illustrative. Suggestions are advice only: nothing changes in your Amazon account without your approval.

Founder

Alice Ho

Alice has sold on Amazon for many years and comes from a technology background.

Every feature runs on TEEZWONDER’s own seller accounts before other sellers see it.

FAQ

Questions sellers ask us

How does OmniSeller connect to my Amazon account?

Through Amazon’s official authorization flow for Selling Partner and Amazon Ads. You never share your Seller Central password with us, and you can revoke access from your Amazon account at any time.

Can I connect more than one brand or marketplace?

Yes. Multi-brand management is built in. The number of connected brands and accounts depends on your plan, from 4 on Starter to 8 on Business, with custom limits on Enterprise.

Does OmniSeller see my customers’ personal information?

No. We do not access or store buyer names, shipping addresses, email addresses or phone numbers. We work only with aggregated business and financial data.

How is net profit calculated?

For each product and period we start from order revenue, subtract every Amazon fee (referral, FBA fulfillment, storage, refunds), subtract advertising spend from Amazon Ads, then subtract the product cost you enter for each SKU.

Is OmniSeller free right now?

Yes. OmniSeller is in invitation-only early access and we are not billing yet. The prices above are our launch pricing for when billing opens, and we will tell invited sellers well before that happens.

How was OmniSeller built?

Alice Ho, our founder, built OmniSeller in house with Claude, including the Amazon Selling Partner and Amazon Ads API integrations and the dashboards. We run it on our own Amazon accounts every day.
