Getting approval without chasing your GC

No account, no download, nothing for them to install — they approve however works for them.

The problem

Chasing down a signature after the fact means phone tag, lost paperwork, and tickets stuck in limbo for weeks.

How Sub's Flow solves it

  1. 1

    Create the ticket

    Log labor, materials, and equipment on-site, right as the work happens — no reconstructing hours from memory back at the truck. Every ticket ties directly to the job it's billed against, with photos attached if you need them.

  2. 2

    Sign off, on the spot

    On your device, by email link, or by QR code — whatever's easiest for the GC rep standing in front of you. There's nothing for them to download or log into first, so the signature captures the moment the work was confirmed, not a guess at it days later.

  3. 3

    Approve (GC touchpoint)

    The one moment a GC rep touches the app at all — no account required on their end. They see exactly what's on the ticket and approve it in seconds, right from their own phone or yours, and nothing else about their day-to-day changes.

  4. 4

    Export for billing

    The signed ticket routes back to your team, ready to hand off to billing. No re-keying hours from a paper copy, no hunting down whoever's holding the signed original.
