Best overall for Amazon brands that want one set of numbers the whole business agrees on.
The operating system for a brand selling on Amazon: one command center across profit, sales, advertising, inventory, content, and customers, with the reason behind every number and the next move.
Strengths
- Accounting-grade P&L reconciled to the settlement, on order, shipment (GAAP), or payout basis
- Six pillars on the same numbers, with Sales and Advertising Diagnostics that rank the drivers behind a change
- One rollup across every marketplace and account, then the same figure per ASIN
- Unlimited users, accounts, and orders on every plan; price grows only with active products
- EU-native: VAT held outside profit, priced in EUR, and data loaded within hours of connecting
Limitations
- Amazon only today; Shopify and off-Amazon connectors are in development
- API access is on the roadmap; today data leaves through CSV, Excel, and Google Sheets exports, plus an MCP server in beta for AI assistants
- Ratings and reviews module, keyword workspace, and dayparting are still in development
- Higher entry price than budget P&L trackers
