The problem

You're losing money in the seams.

Cashback you forgot to track that never posts

Buyers who promised to take 5 units but ghosted on 3

Inventory aging in your closet for months unnoticed

Sales below break-even because tax wasn't in your math

No idea which products actually make money

Spreadsheets with stale numbers from Monday

One system, every workflow

Designed like a trading desk, not a spreadsheet.

Cockpit dashboard

Open the app and know exactly what to do next.

Buyer commitments

Never oversell again.

Track who promised what, what's been paid, what's overdue. Get warned the moment your committed quantity exceeds inventory.

Finance command center

Know your true P&L.

Revenue, COGS, taxes, fees, cashback, gift card savings. Tax-friendly summaries you can hand straight to your accountant.

Smart alerts

The system tells you what's wrong.

Card payment due, cashback expected, commitment overdue, sale below break-even, inventory sitting too long. All surfaced before they cost you.

Inventory truth

In stock, committed, sold, aging. Always live.

10 calculators

Cashback, GC arbitrage, bulk, break-even, what-ifs.

Invite-only

Your data, your circle. No public signups.

Insights engine

Best products, risky deals, margin drops. Surfaced.

Private, by design.
