Day work you never saw is a claim you can't check.

Paper sheets turn up at month end, unsigned or signed by someone who wasn't there. With Workstamp your site manager signs on the day, and only signed, approved sheets reach the month-end summary.

Your limit, checked.

The sub is warned at 80 %. Past 100 % needs their manager's override, and you see it, with the reason, before you sign.

  • At 80 %, a warning.

    The sub sees how much of your instruction is left before they send.

  • Past 100 %, an override you can read.

    Their manager overrides with a reason, and it's on the sheet you sign.

What arrives with every sheet.

When it's wrong.

The sub fixes it and sends the next revision; each revision keeps its own PDF and code.

  • Decline with a reason.

    One line of why. The sub gets it straight away.

  • Propose new hours and sign that.

    If the sub accepts, it becomes the next revision; if not, they reject it with a note.

Month end per sub.

Each sub's approved sheets arrive as one summary. Accept it or dispute it.

Up the chain.

Forward a signed sheet to your own client unchanged. The PDF gains a chain page, so the proof carries through.

Bring your subs.

From now on, please send day work through Workstamp so our site manager can sign it on site. workstamp.app

  • Who pays

    Your subcontractors pay for their own company. Paying for your subs from your own account is coming.

  • Free to receive

    Receiving and signing sheets is free on every plan, including Solo.

Questions

  • Do my subs need a paid plan?

    No. Solo is free: 10 sheets a month, 1 person. Subs who send more pick a plan for their own company.

  • Does it replace Procore?

    No. It covers day work sheets and their proof. Signed PDFs and CSV go into any system.

  • What if a sub won't use it?

    Run paper and Workstamp side by side on one job.

Tell your subs: day work comes signed, or it doesn't come.
