Old process
- Change orders agreed verbally then disputed at payment
- Subcontractors in the field could not access desk scanners
- Unsigned change orders were the top payment dispute source
- Project folders mixed paper and email with no audit trail
With WoltSign
- Subcontract template: GC signs first, sub countersigns on mobile
- Change order template with description and price confirmation checkbox
- Lien waiver at payment milestone with sub signature
- Envelopes organized by project folder
Digital subcontract e-signature for construction moves agreements to subcontractors who work from job sites, not desks. A general contractor with 15 active subs per project sends change orders constantly. Unsigned change orders create payment disputes when scope shifts in the field.
Why GCs need change order e-signature before extra work
Subcontracts, change orders, and lien waivers need signatures under time pressure. Construction document signing must work on mobile browsers. See WoltSign for operations teams.

FAQ
Frequently asked questions
Short answers to the questions teams ask most often about this topic.
Can a subcontractor sign from a mobile phone on a job site?
Yes. The signing link works in any mobile browser. No app required.
Does a digitally signed change order hold up as a contract amendment?
Under ESIGN and UETA, an electronic signature has the same legal effect as a wet signature when the parties have consented to electronic contracting. Consult your attorney for project-specific advice.
Can I require the sub to upload proof of insurance in the same packet?
Yes. Add an Attachment field to the subcontract envelope for COI upload.
