Stop chasing paper on the jobsite. Upload any construction PDF — contract, change order, subcontractor agreement, daily report — and sign it with your finger directly in the Jobsite Sentry app. Legally binding. Timestamped. Done in under a minute.
E-Signature is a feature in the Jobsite Sentry mobile app that lets you upload any PDF construction document and sign it directly on your phone — using your finger or a stylus — from anywhere on site. The signed PDF is timestamped, IP-logged, and legally binding under the U.S. ESIGN Act and UETA. Sign contracts, change orders, subcontractor agreements, daily reports, lien waivers, and any other PDF in under 60 seconds, then share or export the signed copy instantly without printing, scanning, or returning to the office.
No more waiting until you’re back at the trailer. No more chasing subs for a signature. Open the app, upload the PDF, sign on the spot, send it — right from the field.
Pull your PDF from your phone’s files, an email attachment, Google Drive, Dropbox, or iCloud. If it’s a PDF, you can sign it — no conversion needed.
Tap any signature field to open the signing pad. Your actual handwritten signature is captured and embedded directly into the PDF — not a typed font substitute.
Need the sub’s signature too? Send the document to any other party. All signers sign their designated fields and the final PDF collects every signature with its own timestamp.
Tap Finalize to lock and timestamp the document. The signed PDF saves to your Jobsite Sentry account and can be shared by email, download link, or exported to cloud storage.
Every document that used to require a printer, a pen, and a drive back to the trailer can now be signed on the spot.
New sub arriving today but the agreement isn’t signed? Upload the PDF, hand them your phone, and have it signed before they pick up a tool.
Walk the change with the owner on site, pull up the change order PDF, get their signature right there, and send the countersigned copy before you walk back.
End-of-day sign-off done in 30 seconds. Pull up the daily report PDF, sign on your phone, and send the signed copy before you leave the site.
Collect conditional or unconditional lien waivers from subs on the day of payment. Have the signed waiver before the check clears.
Get the safety acknowledgment signed by every worker before the shift starts — right from the app. No clipboards, no lost paper, no missing signatures.
Sign the bill of lading on your phone right at the gate. The signed copy goes to your account and the supplier simultaneously.
Four steps from PDF to signed and sent — all from your phone, all from the field.
Open Jobsite Sentry, go to E-Signature in AI Tools, and upload your PDF from your phone’s files, email, Google Drive, Dropbox, or iCloud. Any PDF works.
The app auto-detects standard signature zones. For custom documents, tap anywhere on the page to drop a signature field, initial block, or date stamp.
Tap the signature field. The signing pad opens. Sign with your finger or stylus — your handwritten signature is captured and placed precisely on the document.
Tap Finalize. The document is timestamped, locked, and saved. Share by email or link, export to cloud storage, or attach to a job record — instantly.
If it’s a PDF that needs a signature, Jobsite Sentry E-Signature handles it.
Prime contracts, subcontractor agreements, owner-contractor agreements, and any binding construction contract requiring one or more signatures.
Field-generated or office-issued change orders and scope change authorizations. Signed by the GC, sub, or owner in the field the same day.
Daily site reports, superintendent logs, and any end-of-day documentation requiring sign-off before submission to the owner, PM, or project file.
Conditional and unconditional lien waivers, partial and final releases. Collected on the day of payment to protect your project from future claims.
Toolbox talk sign-offs, safety orientation acknowledgments, OSHA forms, and hazard recognition forms requiring on-site worker signatures.
RFI responses, punch list completions, certificate of substantial completion, and closeout docs requiring sign-off from the owner, architect, or inspector.
Every signature meets or exceeds U.S. legal requirements for a binding electronic signature.
Compliant with the federal Electronic Signatures in Global and National Commerce Act — legally equivalent to a handwritten signature in all 50 states.
Meets the Uniform Electronic Transactions Act requirements across 49 states — ensuring enforceability for your construction contracts across jurisdictions.
Every signing event records the exact date, time, and IP address of the signer — creating a verifiable audit trail for disputes, arbitration, and legal proceedings.
Once finalized, the signed PDF is locked. Any post-signing alteration is detectable and invalidates the signature record, protecting all parties.
