Estimates · NOC Signatures
Send a written estimate, get an e-signed acceptance back, and start the job with the scope and price locked in — no more "that's not what I agreed to." Every accepted estimate is protected by a legally binding electronic signature with SHA-256 hashes, signer IP capture, and an append-only audit trail.
Documents e-signed through NOC Signatures are enforceable under the federal E-SIGN Act and state UETA. Every signed estimate carries the signer's drawn signature, printed name, title, timestamp, and IP address for non-repudiation, plus SHA-256 hashes of the original and signed PDFs for tamper-evidence. Free for all signed-in NOC Signatures users while in beta.
An estimate is your written proposal — scope, price, assumptions, exclusions. When the customer e-signs it, you have a written acceptance. Many states treat a signed estimate as an enforceable contract for the work described. For larger or more formal jobs, follow up with our Construction Contract product.
A handshake estimate is unenforceable when scope creeps. An e-signed estimate captures the customer's acceptance, IP, and timestamp — the same audit trail we use for NOCs and lien waivers. Disputes get a lot shorter when you can show a signed scope.
Assumptions = facts you're relying on (e.g. "electrical panel has spare 20A capacity"). Exclusions = work you're NOT doing (e.g. "asbestos abatement; permit fees billed at cost"). Being explicit on both protects you from change-order arguments.
Estimates aren't open offers forever — material and labor costs change. The valid-until date sets a clear expiration. Past the date, you can renegotiate or re-issue rather than be locked into stale pricing.
This page is general information about estimates and electronic signatures — not legal advice. Consult a licensed construction attorney for questions about your specific project or state.
