OMNI SELLER CONSTELLATION
Your channels already produce the data. Constellation reads all of it — Amazon, Target Plus, Nordstrom, Shopify, every marketplace and DTC site you sell through — on one contribution-margin basis and runs the same checks every week and every month. What comes back is a short list: the media, listing, restock and assortment changes worth making, with the evidence attached.
Built by marketplace operators. Running on live brand data across Amazon, Target, Nordstrom, Shopify, and more.
The problem
Ad consoles, retailer portals, your storefront and finance each report performance with their own definitions, their own attribution and their own blind spots. The data is there. Reading it on one basis is still someone's job.
Every dashboard shows everything. Another login, another set of charts, and the question “so what do we change?” still lands on someone's desk on Monday morning.
A 5× ROAS can lose money on one retailer and make money on another, depending on price point, return rate and shipping cost. No ad console knows that. Omni Seller Constellation does. Without that floor, budget scales what looks efficient.
Sales, returns, commission, shipping and media need to be reconciled before you can decide what to change. That work happens after the month closes, after the budget already moved.
A sales decline can come from lost availability, a listing issue, a price change, weaker traffic or lower conversion. Separate dashboards show the symptom; tracing the likely cause means reading those signals together before deciding what to fix.
Attributed sales aren't always additional sales. A campaign can take credit for demand that would have arrived anyway, or move it between channels. Understanding what actually grew requires looking beyond ROAS to total sales, organic demand and contribution.
Media, conversion, organic visibility and in-stock availability interact. A budget or assortment decision needs to consider how it may affect the rest of the channel, alongside immediate contribution. Is it supporting profitable growth, or paying to mask a problem elsewhere?
SKU-level reporting can bury the commercial story in sizes, colors and channel-specific identifiers. A style-level view brings those variants together across retailers, while SKU detail shows exactly which size, color or listing needs attention. You need both to make the right assortment and restock calls.
Meet Omni Seller Constellation
Omni Seller Constellation does the work a full-time ecommerce director would do every Monday and every month-end, if they had the time. It normalizes sales, returns, inventory, pricing, advertising and channel terms onto a single product master, then strikes a full contribution P&L at any grain: company, channel, retailer, style or SKU. One style, side by side across every channel it sells on, at true margin — so you can see where it earns and where it's being carried.
Your channel dashboards stay where they are; Constellation reads them on one basis. What comes back is a ranked set of changes, each with the number behind it and the reasoning attached, and each figure stating how much of the catalog it covers.
The commercial picture
The methodology
The method is frozen so a recommendation can be compared with last month's, not so the report looks tidy.
Unknown is never zero.
Every analysis begins with a coverage check: which channels, which date ranges, which data families, which advertising upload windows. A date that no upload covers is unknown, never zero.
Constants such as resale rate, COGS basis and fee terms are versioned. Methodology stays still so performance can move. If an assumption changes, the change is declared and the prior period is restated on the new basis — otherwise the month-over-month delta means nothing.
Where source systems disagree — duplicated return authorizations, inflated order counts, returns attributed to the wrong marketplace — the report shows the direction and magnitude of the variance instead of quietly correcting it.
Every number in every report traces to a numbered note stating its source, its formula and its coverage.
From reporting to decisions
Your channels already produce the data. Omni Seller Constellation reads it on a fixed cadence, using the same methodology and screens, and returns the few changes that matter this week and this month.
One page per retailer that ends in one to three changes for the week ahead: budgets to move, styles to pull media from, restocks needed before adding spend. Headline media KPIs, week-over-week trends, and campaign and style detail provide the evidence. Delivered as the Weekly Media Review.
The channel P&L plus the fixed screens, ending in the decisions for the month. Advertising KPIs and top styles ranked by revenue and by contribution sit side by side; the screens filter for revenue movers by channel, expensive revenue, negative-contribution media, under-invested winners, sub-1× spend, shipping burden, and stockouts holding back spend. Delivered as the Monthly Marketplace Performance Report.
Every review ends in what to change and why. The screens and thresholds are the same every period, so this month's recommendation is comparable to last month's — and every recommendation is reviewed by your Omni Seller team before it reaches you.
What a month reduces to
Fictional data, shown only to illustrate the report format. This is a contribution P&L excerpt, not a live brand report or a statement of product results.
Fictional: 4 channels · 60 styles · 7 screens → 3 recommended actions
Negative-contribution media: pull spend from two styles.
Expensive revenue: review Nordstrom returns before adding budget.
Under-invested winner: restock and fund one style.

Coverage: All figures are invented for one complete illustrative month across four USD channels. No customer data is used. Real reviews state source coverage, missing inputs and known variances before analysis.
How it works
Amazon Seller Central, Shopify, and Acenda — which fronts Target Plus, Nordstrom and other retail marketplaces. Advertising performance is loaded per channel. Unit costs and channel terms are entered on the product master.
Channel SKUs are linked to one master product. Duplicate feeds are excluded. Non-USD marketplaces stay in their own currency on their own line — nothing is silently converted or double-counted.
The same screens run on schedule every week and month, using a frozen methodology. They return only what fired, reduced to the few changes to make with the evidence behind each.
Media budgets, restocks and assortment calls grounded in contribution rather than revenue — made by your team, or by Omni Seller's media managers on your behalf.
Who it's for
Leaders at mid-market consumer brands selling through three or more marketplaces and retailers, who want the few changes that matter each week without reading every dashboard.
In-house or agency — who want ROAS read against margin, and who need to know when a scaled campaign is buying stockouts instead of sales.
Teams who want the reconciliation done once, on a stated basis, so the conversation can be about what to change rather than whose number is right.
A few more answers
No. Most brands already have the numbers. Omni Seller Constellation is the standing review that reads them on one basis and returns what to change. The P&L is the evidence, not the product.
No. Seller Central, Shopify and your retailer portals remain the sources. Omni Seller Constellation reads them on one basis and runs the same screens every week and month, returning a short, ranked list of changes with the evidence attached.
Amazon (every marketplace, each reported in its own currency), Shopify, and any retail marketplace fronted by Acenda — including Target Plus and Nordstrom. Additional channels are scoped per engagement.
No. Omni Seller Constellation returns the few budget and bid changes that the scheduled screens identify, with the number and reasoning behind each. The changes are made by your team or by Omni Seller's media managers — and every recommendation is reviewed by a person before it reaches you.
Today Omni Seller Constellation is delivered through Omni Seller engagements. Brands outside the agency can request early access.
Your data is yours. Any benchmark work uses anonymized, aggregated figures only, is opt-in, and never includes customer PII.
Profit is struck against returns that actually occurred in the period, not against an assumed return rate. It is the harder number to argue with. An accrual lens is on the roadmap for brands that carry expected return rates on their product master.
