What mess does
Everything Sellerboard should have shown you

True profit, not gross fantasy

Every referral fee, FBA charge, and storage cost tracked to the penny — settled figures shown separately from estimates, always.

%

VAT that actually makes sense

See true cash flow and after-reclaim profit side by side, so you know exactly what's yours today and what's coming back from HMRC.

Flags before they're a problem

Unusual fees, thin margins, and high return rates surfaced automatically — not buried three tabs deep in Seller Central.

📦

Inventory that talks back

Days-of-stock, reorder points, and incoming shipments in one place — know what's about to run out before it does.

📱

On your phone, not just a tab

A real mobile app with push notifications the moment a sale lands — not a bookmark you forget to check.

Synced every 5 minutes

No manual "sync" button to remember. Your numbers stay current in the background, automatically.

Built by a seller, for sellers

mess. started as a private tool to answer one question honestly: "did I actually make money on that sale?" Turns out that's harder to answer than it should be.

No black-box profit numbers — every figure is explained
Settled vs. estimated always shown separately, never blended silently
VAT handled the way an accountant would, not a spreadsheet guess
Your data stays yours — private by default
