Why this matters

The change order that doesn't get signed is the change order that doesn't get billed.

Construction work generates paperwork at every step: signed proposals before the work starts, signed work orders when scope is locked, signed change orders when scope changes, signed lien releases when payment is exchanged. The traditional path is a signature on a paper form in the truck or at the kitchen table, then someone in the office scans it (badly) into the project file. Every step has friction; some steps get skipped under pressure; and skipped change orders are unbillable change orders.

CT Signature collapses that. The change order goes out from a template the moment the homeowner agrees to it — signed on their phone in the time the contractor takes to clean up the site. The signed PDF and audit trail land in the project file before the contractor leaves. The work that gets billed is the work that's documented; the friction that used to lose change orders disappears.

For contractor businesses, pay-as-you-go pricing matters. A 2-truck operation that sends 8 documents a month and a 50-person GC that sends 800 each pay for what they send. There's no per-seat tax for adding a project manager or a sub's office manager. The pricing scales with volume, not headcount.

Capabilities for construction

What the platform delivers for trade businesses.

Mobile-first signing for job-site moments

Send a work order or change order from your phone in the truck. Customer signs on their phone at the kitchen table or on the porch. The signed PDF returns before you leave the site. The friction that used to lose change orders is gone.

Reusable templates for standard documents

Build your standard service agreement, common work order template, change order form, and lien waiver into reusable templates. Every future send is a template fill, not a document rebuild. New customer types or new project categories are template variants.

Multi-signer support for subs and partners

Sub agreements that need signature from both the GC and the sub use sequential routing. GC signs first, sub gets notified, sub signs, both have copies with full audit trail. The sub coordination that used to require an in-person meeting is a 24-hour async cycle.

Lien release / waiver workflow

Conditional and unconditional lien releases sent in exchange for payment. Track which releases are signed against which payment milestones. The lien-related compliance that protects the GC and the property owner is documented end-to-end.

Tamper-evident PDFs with audit trail

Every signed contract has a cryptographic signature and an audit certificate showing every action: viewed, signed, IP, device, timestamps. If a customer later disputes the scope or the price, the audit certificate documents what was agreed and when.

Pay-as-you-go pricing

Subscription tiers cover capabilities; volume scales with envelopes sent. A 2-person operation and a 50-person GC each pay for what they actually send. Self-serve onboarding means there's no sales call to get started — sign up and send your first contract today.

What it looks like in practice

A few ways teams use this.

Change order during a kitchen remodel

Halfway through a kitchen remodel, the homeowner decides to upgrade countertops. Contractor pulls out his phone, fills the change order template (line items, new total, signature blocks), sends. Homeowner gets the link, reviews on her phone, signs. Contractor has signed change order before he leaves the site. The work proceeds; the billing is documented; nobody is renegotiating the scope when the invoice arrives.

Subcontractor agreement before the job starts

GC bringing on an electrical sub for a project. Sub agreement template covers scope, schedule, payment terms, insurance requirements. Sequential signing: GC sends, sub signs first, then GC countersigns. Both have signed copies with audit trail before the electrical work starts. The handshake that used to be 'we'll get the paperwork together' is documented before mobilization.

Lien waiver in exchange for progress payment

Property owner ready to make a 50% progress payment. GC sends the conditional lien waiver template — line items match the payment, signature block, payment terms. Owner signs on her tablet, payment is released, GC has signed waiver in the project file. The lien-protection compliance that protects everyone is documented at every payment milestone.

Frequently asked

Common contractor questions.

Are electronic signatures legally binding for construction contracts?

Yes. Federal ESIGN and state UETA laws give electronic signatures the same legal standing as ink for service agreements, work orders, change orders, and most lien-related documents in all 50 states. Some specific lien filings have state-specific filing requirements that may require notarized originals; CT Signature handles the contract and waiver categories where electronic signature is permitted, which is the vast majority of contractor paperwork.

Can customers sign without creating an account?

Yes. Customers receive a secure email link or text-message link, click to open the document on whatever device they have, sign with their finger or stylus. No app download, no account creation. The signed PDF and audit trail come back to the contractor automatically.

Can I send a quick change order without setting up a template?

Yes. Templates save time on documents you send repeatedly, but ad-hoc one-off documents work too. Drop in any PDF, drag fields onto it, send. A one-off change order takes maybe 90 seconds from upload to send.

What about projects with multiple parties (GC, owner, architect, lender)?

Multi-signer routing handles complex signing flows. Sequential, parallel, or mixed orders. Each signer only sees their assigned fields. AIA-style documents that need multiple parties' signatures in specific sequences are supported.

How does the platform handle integrations with construction management tools?

Standard exports for signed PDFs feed common project management and accounting systems. Custom integrations for specific construction-management vendors are available for early-access partners. Most small to mid-size operations use the platform standalone alongside their existing project management workflow.

How does pricing work for a small contractor?

Pay-as-you-go pricing on top of subscription tiers means a small contractor pays for the envelopes they actually send. There's no enterprise sales call required to get started. Self-serve onboarding means you can have your first signed change order before lunch tomorrow.
