The Problem

You're leaving profit on the table. Every single flip.

If you manage flips in spreadsheets, notes, and chat screenshots, you can't maximize what you can't see. Fees get missed. Costs get estimated. Real net profit stays invisible — and your margins shrink without you knowing.

Unknown true margin

Fees, shipping, parts costs — they all eat into profit. But most flippers only track buy and sell price.

Messy inventory tracking

Parts from teardowns live in your head, a box, or a spreadsheet tab nobody maintains.

No repeatable process

Every flip is ad-hoc. No standardized steps from acquisition to sale. No way to compare what works.

How It Works

One workflow. Buy to sale.

FlipStash replaces scattered tools with a single, structured pipeline. Every step feeds the next — and every euro is tracked.

4
Build
Select parts from inventory and assemble new builds. Total cost calculates in real time.
5
