Change Orders

Change Order Software for Plumbers

Scope changes are where plumbing shops bleed money. Create a change order in seconds, get customer approval before you pick up a wrench, and protect your margin on every job.

Free plan. No contracts. Built only for plumbers.

  • Create from any approved estimate
  • Customer approves by text or email
  • Original estimate stays intact
  • Auto-convert to updated invoice

"While you're here, can you also…"

Four words that sink plumbing margins. The homeowner sees a leak under the sink while you're swapping the water heater. The property manager asks about a clogged drain while you're hydro-jetting the main line.

Without a formal change order, one of three things happens: you eat the cost, you awkwardly negotiate on the spot, or you finish the job and fight about the bill later.

Plumb Ace fixes it. Spin up a change order from the approved estimate, add the extra line items, set the new total, and send it for approval — all before you touch the new scope.

Protect every job — in under 60 seconds

From scope change to signed approval before you turn a valve.

  1. 1

    Tap 'Create Change Order' on the approved estimate

    Plumb Ace pulls in every original line item automatically. The customer still has their signed quote — nothing is overwritten.

  2. 2

    Add the new scope and pricing

    Add line items from your template library or write custom ones. Set labor, materials, and any additional fees just like a regular estimate.

  3. 3

    Send for approval by text or email

    The customer gets a clean, branded change order showing the original total, the additions, and the new final price. They tap to approve.

  4. 4

    Auto-convert to updated invoice

    Approval locks in the new scope. The updated total flows straight to the invoice. No retyping, no math errors, no arguments at checkout.

Built to keep your margins intact

Every change order feature is wired into the estimates, invoices, and customer records you already manage in Plumb Ace.

Create from any estimate

One tap creates a change order from an approved estimate. Original scope is preserved. New scope is separate and clear.

Add line items like a quote

Use your template library or write custom descriptions. Labor, materials, and fees — structured exactly like your regular estimates.

Original stays protected

The signed original estimate is never altered. The change order is a separate document with its own approval record.

Customer signs off in seconds

Branded change order sent by text or email. Customer taps to approve from their phone — no printing, no scanning.

Auto-updates the invoice

Approved change orders automatically roll into the final invoice. No manual calculations. No forgotten charges.

Scope alerts for your crew

Techs see the approved change order on their job sheet. They know exactly what's in scope and what's extra before they start.

The jobs that change mid-stream are the jobs that kill profit

A $1,200 water heater swap turns into a $2,400 job when the homeowner discovers a slab leak while you're in the crawlspace. If you don't get that in writing before you start digging, you're either eating $1,200 or having an uncomfortable conversation at checkout.

Plumb Ace change orders put a hard stop to that. New scope goes into a formal document, the customer approves it on their phone, and the updated total is locked in before a single extra fitting is installed.

Your original estimate is still on file. Your customer is still happy. Your margin is still intact.

Stop scope creep

A formal change order makes it crystal clear what's included and what's extra. Verbal agreements become written approvals.

Avoid billing disputes

When the customer signed off on the new total before the work started, there's nothing to argue about at invoice time.

Capture every dollar

Unbilled scope changes are lost revenue. Plumb Ace makes sure every additional sink, valve, and hour gets billed.

Everything you need to handle scope changes professionally

Change orders aren't an afterthought in Plumb Ace — they're a core part of the job workflow. From the moment a customer asks for something extra to the moment the final invoice clears, everything is tracked, approved, and billed.

Free. Cheap. No contracts. No BS.

The big field service platforms charge $49–$699 per month and either don't offer change orders or bury them behind enterprise tiers. You're left managing scope changes with texts and handshake deals.

Plumb Ace includes change orders in every plan — including the free one. Because scope changes aren't a luxury feature. They're a reality of plumbing work.

No setup fees. No annual lock-in. Cancel with one click.

Free forever plan

Change orders included even on the free plan. Protect your margins from day one without spending a dime.

No contracts ever

Month to month. Cancel anytime. We win by keeping you happy, not by trapping you in a 12-month agreement.

Cheaper than everyone

ServiceTitan starts at $245/tech. Jobber is $49–$699. Housecall Pro is $59–$299. Plumb Ace is free to $79 with change orders included.

Built for the truck, not the desk

Scope changes don't happen in the office. They happen when you're under a sink and the homeowner walks in with a new request. You don't have time to drive back and draft a change order on a laptop.

Plumb Ace is mobile-first. Pull out your phone, add the new line items, set the price, and send the change order before you even wipe your hands. The customer approves while you're still kneeling on their bath mat.

Create from anywhere

Every screen is thumb-friendly. Add line items, adjust prices, and send for approval without squinting at tiny buttons.

Under 60 seconds

From scope change to signed approval faster than the homeowner can finish their sentence. Protect the job before you start the work.

Works offline

Draft the change order in a basement with no signal. It syncs the second you're back in range.

Built only for plumbers — not generic contractors

Generic contractor apps treat change orders like project management tickets. They don't understand that a plumbing change order might involve a slab leak discovery, a gas line reroute, or a commercial grease trap replacement.

Plumb Ace speaks plumbing. Your line items say "PEX repipe with pressure test" instead of "additional labor hours." Your customers understand what they're approving. And you never have to explain why a "service call" suddenly costs $800 more.

Stop eating scope changes. Start getting them approved.

The only change order software built exclusively for plumbers. Free to start. No contracts. No BS.
