Built for contractors. Loved by customers.

Sign Off makes it easy to create, share, and collect approval on change orders — so every scope change is documented, agreed upon, and archived before work continues.

How Sign Off works

A simple three-step workflow that keeps contractors and clients on the same page.

Submit a change order

Describe the change in plain language. Sign Off structures it into a clear, professional document automatically.

Notify your client

Your client receives a notification by SMS or email with a link to review the change order details.

Get approval

The client approves or requests changes digitally. You both have a permanent, timestamped record.

Real-world use cases

Sign Off was designed around the situations contractors face every day.

Unexpected Scope on the Job

Your plumber opens a wall and finds corroded pipes that weren't in the original quote. Snap a photo, draft the change order in Sign Off, and send it to your client for review and approval — all before leaving the job site.

Customer-Requested Upgrades

Mid-renovation, your client decides they want upgraded fixtures or a different tile. Document the change, price it out, and get a digital signature — so there are no surprises on either side when the invoice arrives.

Multi-Trade Coordination

Managing a general contract with multiple subs? Sign Off keeps every change order in one place, with a clear approval trail, so electricians, framers, and finish carpenters are all working off the same approved scope.

Dispute Protection

When a client questions a charge months later, you have a timestamped record showing exactly what was approved, by whom, and when. Sign Off creates a paper trail that protects your business.
