  • The paytrader.net app: a bathroom renovation with its four stages, the first released and the second held in escrow, and a button to review photos and approve the stage.
    The paytrader.net mark

    paytrader.net: escrow that pays when the job is done

    Our own product. Money for UK home-improvement work held safely until each stage of the job is confirmed, for homeowners and tradespeople. Mobile apps and a web platform, built so every balance reconciles and every movement leaves a trail.

Apps that feel native.

Web and mobile, and the system behind them. paytrader.net, our own product, is both: the wallet a homeowner checks on a laptop and the app a tradesperson taps on site, built by the same small team.

  • The tradesperson submits proof on the phone; the client confirms on the web; the escrow releases. One codebase, one ledger.
  • Offline first where the signal drops.
  • Hosted if you want, and handed over in your name.
