Contracts & eSignatures
Contracts and E-signature Software for Plumbers
Get every plumbing job signed before the truck pulls up. Plumb Ace generates a clean, legally-formatted service contract from your estimate and lets your customer sign it from their phone — in seconds.
No DocuSign account. No printer. No scanner. No "I'll get back to you tomorrow."
- Signed in seconds from any phone
- Legally binding ESIGN / UETA compliant
- Auto-attached to every estimate
- Signed PDF filed on the customer record
Unsigned jobs are how plumbers get burned
You quote the job verbally. You shake hands. You buy the parts. You spend a day at the property. Then the customer disputes the scope, refuses to pay the deposit, or tells their credit card company they never authorized the charge.
Without a signed contract, you're stuck eating it. With one, you have a clean document showing exactly what was agreed to, when, and by whom — with a timestamped IP address and a clean digital signature.
Plumb Ace makes signing so frictionless that customers actually do it. No app to download. No account to create. Just a text link, a tap, and a signature drawn on the screen.
Plumbing contracts — written for the work you actually do
Generic eSignature tools hand you a blank PDF and wish you luck. Plumb Ace ships with contracts pre-written for plumbing service work, so you can send a legally-formatted agreement in under a minute.
Service agreement templates
Pre-written contracts for water heater installs, repipes, drain work, sewer repairs, fixture installs, and general service calls — already worded for plumbing.
Auto-filled from the estimate
Customer name, job address, scope, line items, total, deposit, and payment terms pull straight from the approved estimate. No double entry.
Liability & warranty clauses
Standard plumbing warranty language, change-order policy, access requirements, and dispute terms built in — written for residential and light commercial work.
Custom contract templates
Save your own contract language once. Reuse it on every job. Edit clauses for service plans, larger installs, or commercial work in seconds.
ESIGN & UETA compliant
Every signature captures the signer's name, IP address, browser, and timestamp — meeting U.S. ESIGN Act and UETA standards for legally binding eSignatures.
Signed PDF on the customer record
Once signed, the contract is sealed as a PDF and filed against the job and the customer — searchable, downloadable, and audit-ready forever.
Estimate, contract, signature — in under two minutes
From job walk to signed agreement without leaving the truck.
- 1
Build the estimate
Pick a plumbing template, adjust line items, and price it for the job. Plumb Ace auto-attaches your matching contract behind the scenes.
- 2
Send by text or email
One tap delivers the estimate and contract together. The customer opens it on their phone — no PDF download, no login, no app install.
- 3
Customer signs on screen
They review the scope, draw or type their signature, and tap Agree. Their IP, timestamp, and device are captured automatically.
- 4
Signed contract is filed
A sealed PDF is saved on the customer record and the job. You get a notification, the customer gets a copy by email, and the job is locked in.
Everything you need to lock in a plumbing job
Plumb Ace pairs every estimate with a real contract — not a one-line "I agree" checkbox. Your customer sees the scope, the total, the warranty, the change-order policy, and the payment terms before they sign.
That clarity is what protects the job. And because the contract is part of the estimate flow, you never have to chase a separate document.

Legally binding — and built to hold up in court
Electronic signatures are legally enforceable in all 50 U.S. states under the federal ESIGN Act and the Uniform Electronic Transactions Act (UETA). Plumb Ace meets both standards on every signed contract.
Every signature event captures the signer's full name, email, IP address, browser fingerprint, and a UTC timestamp. The signed PDF is sealed so any later modification is detectable. If a customer ever disputes the agreement, you have a complete audit trail.
Tamper-evident PDFs
Once signed, the contract is sealed. Any change to the document invalidates the signature — courts and merchant processors recognize this standard.
Full audit trail
Every signed contract carries a signature certificate with IP, device, timestamp, and signer identity. Download it any time you need it.
Dispute-ready
Win chargebacks and small-claims disputes faster with a signed scope of work — not a verbal handshake and a hand-written invoice.
Customers actually sign — because it works on their phone
DocuSign and HelloSign require the customer to create an account, verify their email, and figure out a clunky desktop UI. Most homeowners give up halfway through.
Plumb Ace contracts open in the browser the moment the customer taps the link in your text. They scroll, they sign with their finger or type their name, and they're done — usually in under 30 seconds.
Faster signing means faster deposits, faster scheduling, and fewer jobs that quietly disappear because the paperwork was too much hassle.
No app, no login
Customers sign from the browser. Works on iPhone, Android, tablet, or laptop. No download, no account creation, no friction.
One link, every channel
Send the contract by text, email, or both. The same secure link works everywhere and tracks who opened it and when.
Auto reminders
If a customer hasn't signed in 24 hours, Plumb Ace sends a friendly nudge automatically. No more chasing paperwork yourself.
Change orders get signed too
Halfway through the repipe and the customer wants you to add a new shut-off valve and re-route the laundry line? Spin up a change order from the existing contract, add the new line items, and send it for signature before you pick up another fitting.
The original contract stays untouched. The change order is attached, signed, and filed on the same job — so the final invoice always matches what the customer actually agreed to.
Stop paying for a separate eSignature subscription
DocuSign is $15–$45 per user per month. HelloSign is $20–$30. PandaDoc is $19–$49. None of them know what a tankless install looks like, and none of them are connected to your estimates, jobs, or customers.
Plumb Ace includes contracts and eSignatures on every plan — starting free. Pro is $19/month. Elite is $79/month. No setup fees, no per-signature charges, no annual contracts.
Free forever plan
Send contracts with every estimate on the free plan. No DocuSign, HelloSign, or PandaDoc subscription required.
No per-signature fees
Unlimited contracts and signatures on every paid plan. Send as many agreements as you can quote — no usage caps.
Built into the workflow
Contracts live next to estimates, invoices, jobs, and customers — not in a separate app you have to context-switch into.
