eSignature for construction · Updated
E-signatures for contractors and construction companies
On a job site, a change order signed today can prevent a payment dispute next month. Contractors need signatures from clients and subcontractors quickly, often from a phone.
eSignSimple works in any mobile browser, so clients can approve contracts and changes on the spot, with an audit trail for every document.
Most payment disputes in construction are really scope disputes. Someone asked for an extra outlet or a different tile, someone else agreed on the phone, and months later nobody remembers the price. A signed change order, dated and tied to the original contract, ends that argument before it starts.
Our take: contractors do not need a construction ERP to fix this. They need to be able to send a one-page change order from the truck, have the homeowner sign it on their phone while standing in the kitchen, and get a PDF with an audit trail back in their inbox.
What slows down paperwork in construction?
Undocumented changes
Verbal approvals lead to disputes. A signed change order records scope and price. Put the price, the extra days on the schedule and a short description of the work in writing, every time.
Working from the field
Send and sign from a phone without returning to the office. The signing page is built for small screens, so clients can review and sign without zooming around a desktop layout.
Many parties
Owners, general contractors and subcontractors can each sign in order. Signing order lets the owner approve first and the general contractor confirm, with every step time-stamped.
Paper does not survive the site
Printed contracts get rained on, covered in dust or left in the van. A signed PDF in your inbox is the copy that still exists when the invoice is disputed.
Subcontractors without office staff
Many subs are one- or two-person outfits who run their business from a phone. A link they can sign between jobs gets agreements back faster than a scan-and-email request.
Which documents do construction teams sign with eSignSimple?
| Document | Who signs | How it works in eSignSimple |
|---|---|---|
| Construction contract | Owner, contractor | Start from the construction contract; upload your own Word version if you have one. |
| Change order | Owner, contractor | Send the change order from your phone and have the client sign on site. |

How do you get the most out of e-signatures in construction?
- Get every change order signed before work begins.
- Some states require specific notices in home improvement contracts; check local law.
- Mechanics' lien documents may have special filing or notarization rules.
- Reference the original contract number or address on every change order so the documents clearly belong together.
- Photograph the site before and after changes and attach the photos to the change order PDF.
- Our take: set a simple rule for your crew that no extra work starts without a signed change order. It feels awkward the first few times and saves you from being the one who absorbs the cost.
- Save a change order template with blank fields for description, price and extra days, so the foreman only fills three things on site.
- Get the client's email address right on day one; signing links go by email, and a typo found at the kitchen island wastes the moment.
- Signing from the truck? Our guides on signing a PDF on iPhone and on Android cover the mobile side, and the change order template is a good first template to save.
Before you rely on an e-signature for a specific document, check the rules where you work: see e-signature law in the United States, the United Kingdom or other countries, and read how we store and protect signed documents.
How does a change order get signed on site in five minutes?
Picture a kitchen remodel. Halfway through, the homeowner asks the foreman to move the island outlet and upgrade to a larger tile. The foreman prices it at $1,240 and two extra days. Standing in the kitchen, he opens the saved change order template on his phone, types the description, the price and the schedule change, references the original contract number, and sends it to the homeowner's email.
The homeowner opens the email on her own phone, reads the one page, and signs with her finger. A minute later the completed PDF with its certificate of completion arrives in both inboxes and in the office. The extra work starts that afternoon with a signed price behind it, instead of a verbal yes that will be remembered differently when the final invoice arrives.
Two details make this work. Keep the template to one page, because nobody reads three pages on a phone in a dusty kitchen. And send from the job, not from the office that evening: the moment the client agrees in person is the moment they will sign.
Who should sign a change order: owner, contractor, architect or sub?
On a residential job, it is usually just the homeowner and the contractor. Have the homeowner sign first, since they are approving the cost, and the contractor confirm. On commercial work, the main contract decides: many require the owner's representative, the general contractor and sometimes the architect to sign every change. Read the change clause and copy its signatories into your template's signing order.
Subcontractors are a separate step. When an owner-approved change affects a sub's scope, the general contractor issues a matching change to the sub under the subcontract. Send it right after the owner signs, using signing order sub first and GC last, so the price you agreed upstream is locked downstream before the work starts.
What if the client will not sign the change order?
Do not start the extra work. That is the whole point of the rule, and a client who will not sign today usually has a question about price or scope that is better answered now than at the final invoice. If they decline in the signing page, the decline is recorded with the time. Talk it through, adjust the scope or price, void the old change order and send the revised one.
If the client simply goes quiet, paid plans send reminders every 3 days, up to 3 times. Meanwhile, keep working to the original scope. A pending change order with a timestamp is still useful: it shows you raised the change and its cost before doing the work, which matters if the client later claims the extra was included.

Frequently asked questions
Are e-signatures legally binding for these documents?
In most cases, yes. Simple electronic signatures are recognized under the US ESIGN Act, UETA and the EU eIDAS Regulation. Some documents, such as wills or certain court and real property filings, may need wet ink, witnesses or notarization depending on the jurisdiction.
Can clients sign on a phone?
Yes. The signing page works in any mobile browser.
Is it legal to e-sign construction contracts?
Generally yes. Construction contracts and change orders are ordinary commercial contracts, which ESIGN and UETA cover in the US. Some states require specific notices or cancellation rights in home improvement contracts, and lien documents may need notarization. See our US legality page and check state rules.
Can I send a change order from the job site?
Yes. You can upload and send from a phone browser, and the client signs on any mobile device without an account.
Does every change order count against my monthly limit?
Yes. Each document counts once when it is sent. The Free plan covers 3 documents a month and Bronze covers 25; if you write several change orders a week, Silver at $9.99/month removes the limit. See pricing.
Can my office manager and foremen share the same templates?
Yes, on Gold: up to 5 senders share templates such as your change order and contract, while each sender's documents stay their own.
