Construction agreements, finally understood.
“Is my subcontractor sure what they agreed to?”
XOsign reads the subcontracts, change orders, and lien waivers your crews and subs actually sign — explains them in plain language, translates them for Spanish-speaking crews, and gets them signed on any device, right on the jobsite.
- Read and sign in English or Spanish — on any device.
- NOCs, NTOs, lien waivers, COI tracking and AIA pay apps — the Construction Pack.
“Indemnification” means one party agrees to cover the other's losses or legal costs if something goes wrong.
Most tools stop at the signature. XOsign starts four steps earlier.
Make sure every crew and sub understands the deal.
On most jobs the person signing is not the person who wrote the contract — and often not reading in their first language. XOsign puts the agreement in plain language and side by side in English and Spanish, so consent is genuine and disputes get rarer.
- Plain-language explanation of every clause that matters.
- English and Spanish side by side, from the same source document.
- Translations built to preserve the legal meaning of the original.
- Tap any term to understand what it actually commits you to.
The Contractor shall provide indemnification to the Client for claims arising from the work performed under this Agreement.
El Contratista proporcionará indemnización al Cliente por reclamaciones que surjan del trabajo realizado en virtud de este Acuerdo.
Una parte cubre las pérdidas o los costos legales de la otra. Tap any term for a plain-language explanation.
Know what is in the contract before you sign it.
XOsign reads construction documents the way a careful reviewer would and flags the terms that decide who gets paid and who carries the risk — the ones that cost real money when they are missed.
Indemnification & hold-harmless
Who carries the liability when something goes wrong on site — and how far that obligation actually reaches.
Retainage & payment terms
How much is held back, when it is released, and the schedule that decides when you actually get paid.
Pay-when-paid / pay-if-paid
Whether you get paid only after the owner pays the GC — one of the most consequential lines in any subcontract.
Termination & default
How the agreement can be ended, what counts as a default, and the cure period you are given to fix it.
Scope gaps & exclusions
What is in the scope, what is quietly excluded, and the gray areas that turn into change-order disputes.
Change-order pricing
How extra work gets priced, approved, and documented — before a crew ever picks up a tool.
Lien & notice deadlines
The notice-to-owner and lien deadlines the job runs on — surfaced and tracked so none of them pass unnoticed.
Insurance & COI requirements
The coverage limits and additional-insured language you are agreeing to carry for the life of the job.
Refine the terms that govern your payment and your crew.
Beyond reading the contract, XOsign suggests where it is thin — missing clauses to add and vague language to tighten — so the agreement you send is clearer than the one you received.
- Flag missing clauses a subcontract should include.
- Clarify payment, retainage, and pay-application terms.
- Firm up termination, notice, and cure-period rights.
- Close scope and change-order gaps before they become disputes.
Sign on any device — or in person, right on the jobsite.
Send an agreement by email or text, or hand your phone or tablet to a sub standing in front of you and sign in person. Every signer sees the document in their language first, and you keep a signing record you can verify later.
- General contractor and subcontractor both sign.
- Works in the trailer, the truck, or the field.
- A signing record you can verify after the job.
Built for the documents construction runs on.
These are not generic contracts. XOsign is built for the specific paperwork that moves a job from bid to final payment.
Subcontracts
The agreements your subs actually work under, read clause by clause.
Change Orders
Extra work, priced and agreed before it starts — not after the dispute.
Purchase Orders
Materials and equipment on clear terms, with the fine print surfaced.
Notices to Owner (NTO)
Preserve your right to get paid, with the deadlines called out.
Lien Waivers
Conditional or final — understand exactly what you are releasing.
Pay Applications (G702/G703)
Progress billing your GC will recognize, explained line by line.
Insurance / COI
The coverage and additional-insured terms everyone on site carries.
Scope of Work
What is included — and, just as important, what is not.
Independent Contractor Agreements
Clear, understood terms for the 1099 crews you bring on.
Everything the job needs to get paid — and stay compliant.
Reading and signing contracts is the start. The Construction Pack adds the paperwork that decides whether you actually collect: notices, notarization, certified mail, compliance documents, lien waivers, and billing your GC will recognize. It unlocks Money and the Compliance Vault.

Notices of Commencement
Draft the § 713.13 NOC, get it notarized and recorded with the county, then track the recording and posting from one place — with a warning before it lapses and exposes the job.
Online notarization
Book a commissioned notary in a live video session, right from the document. The sealed, notarized PDF comes back into the job file — no appointment, no driving, no printing.
One-click USPS certified mail
Send any document as certified mail without leaving your desk. XOsign formats it, mails it, and tracks it — so you have the green-card proof of service the statute expects.
Compliance packages
Bundle the documents a GC or owner always asks for — W-9, COI, licenses, waivers — into one named package tied to a client or project, and send the whole set with a single tracked link.
License & COI monitoring
XOsign reads each certificate for limits, additional-insured status and endorsements, then watches the expiration dates. You get reminders before coverage lapses, and a dashboard showing which subs are green, expiring or missing.
Lien waivers
All four Florida § 713.20 statutory waivers — conditional or unconditional, partial or final — prefilled from the client and project, grouped so you can see which ones you sign at your own risk, then sent for signature.
Notices to Owner
Build the § 713.06 NTO, serve it by certified mail or notary, and let the clock run in the background: the 40-day mail-by date, the 45-day deadline, and the 90-day Claim-of-Lien window all come back as reminders.
Compliant pay applications
AIA-shaped G702/G703 — the nine numbered cover lines, retainage, and less-previous-certificates on page one, the continuation sheet on page two. A pay app cannot go out unsigned or undated.
Change orders that flow through
Approve a change order and it rewrites the schedule of values into a new version with the price change baked in — so the next draw bills against the contract sum as it actually stands, not as it started.
