What it does
The parts of five different tools a seller actually looks at, on one page per marketplace.
Profit and loss that adds up
Sales, ads, fees, refunds, shipping and cost of goods for today, yesterday, month to date and last month, with the previous period beside each. Amazon fees come from the posted events, not an estimate.
Costs you're missing
Any order whose SKU has no cost on record asks you for one, right on the order row. Enter it once and every past order re-costs itself.
One master catalog
Amazon is the master. Titles, images, prices and quantities flow to Walmart, eBay and Shopify every morning, with every change and outcome logged.
Listing health
Amazon's own quality alerts and issue codes, Walmart's rejected SKUs and the reasons, and the eBay and Shopify twins that are missing or mismatched.
Inventory planning
Days of cover per SKU from real shipment velocity, what to send to FBA for six weeks, and the cheapest way to get it there.
Targets and alarms
A daily sales target per store with a sparkline of the last 30 days, and an alarm when a marketplace stops sending orders.
How it works
Read-only by default. Anything that writes to a marketplace is dry-run first and applied only when you say so.
Connect your stores
Amazon Selling Partner, Walmart Marketplace, eBay and Shopify through each platform's own app authorisation. No pasted passwords.
Set your costs and targets
Import costs from a spreadsheet or type them as orders come in. Pick a daily target per store.
Open one page each morning
Every marketplace on one screen, plus a short written brief of what changed and what needs you.
