Multi-marketplace EC sales, made visible in one view by product × platform × week.
We consolidate sales data from Rakuten, ZOZOTOWN, Amazon, Yahoo!, your own D2C store, and more into a single BI dashboard (equivalent to Looker Studio/Metabase) that you can access anytime. On top of that, for the KPIs you need to track, an AI writes a weekly report covering why sales rose or fell and what to do next — reviewed by an analyst with hands-on e-commerce experience and delivered automatically.
The more marketplaces you add, the harder it is to see the full picture
Recurring scenes for EC sellers running multiple marketplaces.
Monday morning starts with opening a stack of admin dashboards
Rakuten RMS, ZOZOTOWN, Amazon Seller Central, Yahoo!, your own store. Just pulling together last week's sales eats your whole morning — and you still can't break it down by product.
You can't answer "where should this product actually sell?"
The same product might do better on Rakuten one week and Amazon the next. You can sense it, but without numbers to back it up, ad spend and inventory allocation stay a guessing game.
You always notice the post-sale slump too late
After a major sale event, your best sellers often drop off — but you don't notice until month-end close. By the time you act, the next sale is already here.
A stack of admin dashboards, turned into one BI dashboard
Sales, inventory, and SKU-level views. Scroll to see the actual screens. The dashboard is available anytime — not just something you check once a week.
Sales View
See what's selling, and where
Sales by product × platform, shown through KPI summaries and weekly trend charts. The dashboard is always accessible — you'll see the latest numbers every time you open it.

The KPIs you need to track, sent to the tools you already use
Delivered automatically on a set morning each week, separate from the dashboard. You never have to open the dashboard just to see the report.
Why it happened, and what to do next
You don't need to open the dashboard every time. A weekly summary, key findings (why the numbers moved), and next actions arrive automatically, in plain language, on a set morning each week.
Did last week's suggestion get done?
We track every week whether last week's recommendation was acted on, and what happened as a result. Reports never end at "delivered and forgotten."
Ask us anything, anytime
Ask "how should I read this number?" over email or chat as often as you like. You stay in control of operations — we hand you the information to decide.

We build the BI dashboard
We build a BI dashboard, available anytime, that automatically aggregates by product × platform × period. Quoted individually based on the number of marketplaces you need connected.
A human reviews it
An analyst with hands-on e-commerce experience checks the interpretation and turns it into the one move to make this week.

Every week, on a set morning, the weekly AI report arrives automatically — delivered separately from the dashboard.
Build and analysis run on an AI pipeline designed by an analyst with hands-on e-commerce experience, reviewed by a human every week before delivery.

Send us the CSV exports from each marketplace's admin panel, and we'll consolidate sales for the same product side by side into a single BI dashboard broken down by product, platform, and period. If you sell on a marketplace not listed here, just ask whether we can support it. Ad performance (GA4 × each ad platform) can also be built into the same dashboard.
