Detailed Comparison

1. Jobber: Best for Growing Plumbing Teams That Need Quoting, Scheduling, and Invoicing in One Tool

Jobber is one of the better apps for trades work, covering scheduling, invoicing, payments, reporting, and even a website widget in one platform. It’s built for small-to-mid-size plumbing shops that want clean workflows without an enterprise price tag or a six-month implementation.

At a Glance

Category Detail
Location Edmonton, Canada
Founded 2011
Users 250,000+ companies worldwide
Best For Plumbing teams of 1-15 needing quotes, scheduling, and invoicing
Notable Clients Verify on vendor site
Specialization Field service job management

Differentiator: Jobber ties quoting, job scheduling, and invoicing into one linear workflow so nothing falls through the cracks between the estimate and the final bill. It simplifies scheduling, quoting, invoices, and client communication all in one place, which makes a real difference as a company adds employees and recurring routes.

  • Automated invoice follow-ups chase unpaid balances without you lifting a finger
  • Client hub lets homeowners approve quotes and pay invoices online
  • Mobile app is excellent for field techs managing jobs on-site

Proof point: Jobber has a G2 rating of 4.6/5 from 478 verified reviews, ranking it as the number one tool in two field service categories on G2’s 2026 Best Software Awards.

Limitation: Once your team hits 10:15 people, the per-user pricing becomes a real problem. You’re paying a premium for simplicity, and the tools you’d expect at that price point, like advanced reporting, aren’t always there.

  • Team plans jump sharply: $149/mo for 5 users, $529/mo for 15 users
  • No built-in AI call answering or after-hours lead capture

Who it’s for: Plumbing businesses with 1:10 techs that want a single tool to run quotes, jobs, and invoices without stitching together separate apps.

Who it’s NOT for: Large plumbing operations with complex dispatching, multi-location reporting, or enterprise CRM needs.

Pricing Breakdown

Core (Solo) $39/mo Invoicing, scheduling, client management

What Users Say

Love: Clean interface and fast invoice creation

G2 reviewers consistently praise Jobber for making scheduling, inputting clients, and invoicing super easy, with a dashboard that allows rescheduling and assignment flexibility without losing opportunities.

  • Setup is fast and the mobile app works reliably in the field

⚠️ Complain: Per-user pricing gets painful at scale

Once teams grow beyond 10, 15 people, the pricing structure becomes a significant concern, with advanced reporting tools not matching what buyers expect at that price point.

  • Jobber occasionally drops line items during QuickBooks sync, about 2% of the time in independent testing.

2. ServiceAgent: Best for Adding AI Call Answering and Automated Payments on Top of Your Plumbing Software

ServiceAgent is not a plumbing invoice tool. It’s the AI front office layer that pairs with whatever invoicing or FSM tool you already use, answering every inbound call, booking jobs, and processing payments 24/7 so you stop losing work after hours. If your current software handles the invoice but your phone goes unanswered at 9pm, ServiceAgent fills that gap.

At a Glance

Category Detail
Location Austin, Texas
Founded 2024 (launched April 2025)
Users Early stage; customers in solar, plumbing, and roofing trades
Best For Service businesses with high inbound call volume wanting an AI front office layer
Notable Clients Aurora Energy Solutions, Greenflow Plumbing, Summit Peak Roofing
Specialization AI Front Office Platform for service businesses

Differentiator: ServiceAgent is not a replacement for your CRM or FSM. It’s the AI layer that sits above your existing stack, answering calls, booking appointments, sending invoices, and following up on unpaid balances, all without a human receptionist. It connects to 70+ tools including Jobber, Housecall Pro, ServiceTitan, Stripe, and QuickBooks.

  • Plumbing GPT: a voice AI tuned specifically for plumbing emergency intake and dispatch
  • 100% call answer rate after deployment, no more missed jobs after 5pm
  • Free platform, pay only per call handled and per payment processed

Proof point: ServiceAgent reports a 75% booking conversion rate via its public booking widget versus a 15% baseline, and a 77% reduction in no-shows through automated reminders. Parent company SaaS Labs has raised $74M (Sequoia-backed) and builds JustCall.io, a proven telephony platform.

Limitation: ServiceAgent launched in April 2025 and is early stage. It doesn’t have G2 or Capterra ratings yet, and its AI voice quality for highly complex plumbing dispatch scenarios should be tested on demo before committing. It’s also not a standalone invoicing tool: you still need an FSM or accounting tool for full job costing.

  • No G2 or Capterra rating yet (launched April 2025)
  • Not a replacement for Jobber, ServiceTitan, or QuickBooks job costing

Who it’s for: Plumbing businesses with 20+ inbound calls per day that want AI handling intake, booking, and payment follow-ups on top of their existing invoicing or FSM tool.

Who it’s NOT for: Shops looking for a single all-in-one FSM and invoicing platform with job costing and dispatch boards.

Pricing Breakdown

Plan Price Key Features
Free Platform $0/month Full CRM, scheduling, payments, booking widget

What Users Say

Love: Free to start, no subscription risk

Product Hunt reviewers give ServiceAgent 5.0/5 at early stage, citing the free usage model as a major differentiator for small service businesses tired of stacking monthly SaaS fees.

  • Plumbing GPT voice agent handles emergency intake without a human on call

⚠️ Complain: Too new for deep review data

No G2 or Capterra reviews exist yet given the April 2025 launch. Buyers should request a live demo and test the voice agent with real plumbing scenarios before going live.

  • Early-stage product: integrations and edge cases still being refined

3. Housecall Pro: Best for Small Plumbing Crews That Want Fast Dispatch-to-Invoice

Housecall Pro gets you from booked job to paid invoice faster than almost anything else at its price point. It’s built for small plumbing teams that want scheduling, dispatching, and invoicing in one mobile-friendly tool without a steep learning curve.

Location Denver, Colorado (formerly San Diego, California)

Users 45,000+ businesses (200,000+ home service pros)
Best For Small plumbing teams needing fast dispatch-to-invoice workflow
Notable Clients Verify on vendor site
Specialization Field service management for home service pros

Differentiator: Housecall Pro stands out for its real-time scheduling and online invoicing, with many reviewers noting its ease of use and mobile accessibility. Techs can send an invoice from the job site in under a minute, and customers can pay by card on the spot.

  • Financing options and mobile check deposits built into payments
  • Automated review requests sent after each completed job
  • Housecall Pro has the cleanest QuickBooks integration for smaller operations

Proof point: Housecall Pro is trusted by over 45,000 businesses and holds a G2 rating of 4.4/5 from 202 verified reviews, with 69% of reviewers giving it five stars.

Limitation: Pricing is seen as high for small teams and inconsistent with feature availability, and some users cite calendar sync issues and invoice formatting limitations.

  • Basic plan at $69, 79/mo has no GPS tracking, no QuickBooks integration, and limited support
  • Calendar sync issues and invoice formatting limitations frustrate users on lower tiers

Who it’s for: Plumbing shops with 1:5 techs that want a simple, mobile-first tool to dispatch jobs and collect payment the same day.

Who it’s NOT for: Larger plumbing operations that need advanced job costing, multi-location dispatch boards, or detailed financial reporting.

Pricing Breakdown

Plan Price Key Features
Basic From $59/mo (billed annually) 1 user, scheduling, dispatching, invoicing, estimates, online booking
Essentials From $149/mo (billed annually) Up to 5 users, QuickBooks sync, employee GPS tracking, automated follow-ups
MAX From $299/mo (billed annually) Advanced custom reporting, open API integration, sales proposal tool, recurring service plans

What Users Say

Love: Mobile-first, easy to use from day one

Capterra users consistently highlight Housecall Pro’s ease of use and mobile accessibility as its top strengths, especially for small teams in the field.

  • Setup takes hours, not weeks, and techs pick it up without training

⚠️ Complain: Pricing jumps and missing features on lower tiers

The Basic plan at $69, 79/mo lacks GPS tracking, QuickBooks integration, and strong support, making it expensive compared to alternatives at that price point.

  • Some users report inconsistency between what features are advertised and what’s actually available on their plan

4. ServiceTitan: Best for Large Multi-Tech Plumbing Operations That Need Enterprise Billing

ServiceTitan is the heavyweight. It’s built for plumbing companies running 10+ techs across multiple locations that need serious dispatch boards, CRM, and billing workflows all under one roof. The price reflects that.

At a Glance

Category Detail
Location Glendale, California
Founded 2007 (launched platform commercially in 2012)
Users 10,800+ active commercial customers (representing 100,000+ field technicians)
Best For Large plumbing operations needing enterprise dispatch, CRM, and billing
Notable Clients Verify on vendor site
Specialization Enterprise field service management

Differentiator: ServiceTitan is the number one software platform for managing a service business, trusted by over 100,000 professionals, and it incorporates industry best practices to help streamline operations, improve sales, and manage costs. Its billing and invoicing module is deeply tied to job costing, customer lifetime value tracking, and marketing attribution.

  • Tracks customer lifetime value, service history, and equipment records per job
  • Multi-company support: manage residential, commercial, and new-builds in one platform
  • Advanced dispatch board with real-time technician GPS and job status

Proof point: One verified G2 reviewer running three plumbing companies in one (service, new-homes, and commercial) credits ServiceTitan with managing all three with a single piece of software. G2 rating: 4.5/5 from 345 reviews.

Limitation: ServiceTitan pricing ranges from $245 to $398 per technician per month. For a company with 5 technicians, that’s roughly $1,225 to $1,990 per month in software fees alone.

  • Some parts of the product aren’t very intuitive, requiring frequent reliance on the support team
  • Long implementation timelines: not a tool you spin up in a day

Who it’s for: Plumbing businesses with 10+ techs, multi-location operations, or those needing enterprise-grade job costing, CRM, and reporting.

Who it’s NOT for: Small or solo plumbing shops. The cost and complexity will overwhelm a team of 1:5.

Pricing Breakdown

Plan Price Key Features
Starter $245–$300/tech/mo Core dispatch, invoicing, basic CRM, payments, scheduling
Essentials $300–$400/tech/mo Advanced CRM, custom reporting, integrations, customer portal
The Works $400–$500+/tech/mo Full platform: configurable payroll, inventory, advanced analytics, marketing tools

What Users Say

Love: Consolidates everything for complex operations

G2 reviewers running multi-entity plumbing companies specifically praise ServiceTitan’s ability to manage service, new-homes, and commercial work inside a single platform.

  • Dispatch board and real-time job tracking are consistently rated as top features

⚠️ Complain: Expensive and support can be slow

A G2 reviewer noted: “The product is complicated, which means you need help regularly, but their product support is TERRIBLE.”

  • At $245, $398 per tech per month, cost is a major barrier for smaller plumbing operations

5. Field Edge: Best for Plumbing Businesses That Live Inside QuickBooks

Field Edge is a field service management tool built specifically for HVAC, plumbing, and electrical contractors that want deep QuickBooks integration. If your bookkeeper runs everything in QuickBooks, Field Edge keeps the field and the books in perfect sync.

At a Glance

Category Detail
Location Atlanta, Georgia (with offices in Fort Myers, Florida)

Users 40,000+ contractors
Best For Plumbing shops needing deep, real-time QuickBooks two-way sync
Notable Clients Verify on vendor site
Specialization FSM for plumbing, HVAC, and electrical contractors

Differentiator: Field Edge features deep two-way QuickBooks sync, including job costing, and its mobile app lets technicians manage their full day from their phone: clocking in, viewing job details, capturing photos, collecting payment, and sending the invoice, all without going back to the office.

  • Real-time past-due balance visibility when creating invoices in the field
  • Price book on mobile: techs find and quote line items without calling the office
  • Red-flag feature marks do-not-service customers across the whole team

Proof point: G2 reviewers specifically highlight Field Edge’s QuickBooks communication and the ability to see real-time past-due balances and create and accept quotes on both mobile and desktop as key benefits.

Limitation: Field Edge does not publish pricing publicly, which makes it harder to compare against alternatives without sitting through a sales call. G2 reviewers also flag navigation issues for office staff.

  • Platform does not allow office staff to access jobs in some configurations, and it frequently locks out technicians and office staff
  • Only 83 G2 reviews: less social proof than Jobber or Housecall Pro

Who it’s for: Plumbing businesses with an established QuickBooks workflow that need field-to-office sync without rebuilding their accounting setup.

Who it’s NOT for: Shops that don’t use QuickBooks or want transparent, publicly listed pricing before talking to sales.

Pricing Breakdown

Plan Price Key Features
Select Custom Quote (Estimated $100–$150/user/mo) Core dispatching, live scheduling, basic quotes, customer management, QuickBooks sync
Premier Custom Quote (Estimated $150+/user/mo) All Select features, plus service agreements, advanced custom reporting, flat-rate price book
Elite Custom Quote All Premier features, plus unlimited saved reports, outbound call recording, Proposal Pro, MarketingEdge with 2-way texting, and inventory management

What Users Say

Love: QuickBooks sync and mobile invoicing work reliably

G2 reviewers praise Field Edge for its real-time QuickBooks communication, past-due balance visibility, and the ability to create and accept quotes on both mobile and desktop.

  • Techs can send invoices and collect payment from the job site without office involvement

⚠️ Complain: Navigation is clunky and pricing is opaque

Capterra reviewers report that the platform is hard to handle for both technicians and office staff, and that it frequently locks users out with no clear resolution from support.

  • Pricing requires a sales call, which slows down the evaluation process

6. Invoice2go: Best for Solo Plumbers Who Just Need Fast, Professional Invoices on the Go

Invoice2go does one thing well: it gets a professional invoice into a customer’s inbox in under two minutes from any phone. It’s not an FSM, it’s not a CRM. It’s a mobile invoicing tool built for plumbers who don’t need a full platform.

Notable Clients Verify on vendor site
Specialization Mobile invoicing and estimates for small businesses

Differentiator: Invoice2go strips invoicing down to its simplest form: add your logo, enter the job details, send. It has an overall average rating of 4.3 out of 5 from verified users on Capterra, and it provides three invoicing plans tailored to the needs of all types of small businesses.

  • Converts estimates to invoices in one tap once a customer approves
  • Recurring invoice support for maintenance contract customers
  • QuickBooks and Xero integration on the Premium plan

Proof point: Invoice2go gets ratings of 4.3/5 on G2 (from 89 reviews) and 4.1/5 on Trustpilot (from 3,300+ reviews), indicating broad adoption and consistent satisfaction among freelancers and small operators.

Limitation: Invoice2go is invoicing-only. There’s no scheduling, no dispatch board, no job management, and no built-in CRM. It also gets expensive relative to its feature set compared to tools like Jobber.

  • Capterra users flag that it’s “a bit expensive for what it offered compared to other options”
  • No scheduling, dispatch, or job management at any price point

Who it’s for: Solo plumbers or 1:2 person crews that just need to send clean invoices and get paid fast, without paying for features they’ll never use.

Who it’s NOT for: Any plumbing business with more than one tech, recurring dispatch needs, or a requirement for job costing.

Pricing Breakdown

Starter $5.99/mo Create up to 2 invoices/mo, client communications, website builder

7. QuickBooks Online: Best for Plumbing Businesses That Want Accounting-First Invoicing

QuickBooks Online isn’t built for plumbers specifically, but it’s the accounting backbone of millions of small businesses, and its invoicing is solid. If your accountant already uses it and you want invoicing tied directly to your books, it’s a natural fit.

Best For Plumbing businesses wanting invoicing tied directly to accounting
Notable Clients Verify on vendor site
Specialization Small business accounting and invoicing

Differentiator: QuickBooks Online gives you invoicing that’s native to your accounting ledger. Every invoice you send automatically hits your P&L, tracks accounts receivable, and reconciles with your bank. No export, no sync, no gap.

  • Customers can pay bills with one click from an emailed invoice, and you can also send a text payment link
  • Connects to nearly every other plumbing tool via native integrations or Zapier
  • Accountant access built in: your bookkeeper works in the same system

Proof point: QuickBooks Online holds a G2 rating of 4.0/5 from 3,759 verified reviews, making it one of the most widely reviewed accounting and invoicing tools in the small business category.

Limitation: QuickBooks Online has no plumbing-specific features. There’s no scheduling, no dispatch, no job photos, and no field service workflow. You’ll need a separate FSM tool alongside it, which means more subscriptions and more data entry.

  • No scheduling, dispatch board, or job management
  • Some users report frustration with customer support when trying to resolve billing or linking issues, and are told to pay for help with basic tasks

Who it’s for: Plumbing businesses with an accountant who already uses QuickBooks, or owners who want invoicing and bookkeeping in one place without a separate accounting tool.

Who it’s NOT for: Plumbers who need scheduling, dispatch, and job management: QuickBooks doesn’t do any of that.

Simple Start $38/mo Invoicing, expense tracking, basic reporting
Essentials $75/mo 3 users, bill management, time tracking
Plus $115/mo 5 users, inventory, project profitability
Advanced $275/mo 25 users, custom reporting, dedicated support

What Users Say

Love: Invoicing tied directly to accounting books

Capterra users love that customers can pay with a single click from the invoice email, calling it a stable program that gets continual updates and rarely requires support.

  • Accountants already know it, which cuts onboarding time to zero

⚠️ Complain: Support is hard to reach for basic problems

Capterra reviewers report being told to pay for help with basic invoice-linking tasks that should be self-service, which frustrates small business owners on tight budgets.

  • No plumbing-specific features: you’ll still need a separate FSM tool

FAQs

What’s the best invoicing software for a solo plumber?

Invoice2go or Jobber’s Core plan at $29/mo. Invoice2go is cheaper if you just need to send invoices fast. Jobber is better if you also want scheduling and automated follow-ups. Don’t pay for ServiceTitan or Housecall Pro at this stage.

Can I use QuickBooks for plumbing invoicing?

Yes, and it works well if your accountant already uses it. But QuickBooks has no scheduling or dispatch features. You’ll need a separate FSM tool like Jobber or Housecall Pro alongside it, which means two subscriptions.

What’s the difference between plumbing invoicing software and field service management software?

Invoicing software sends bills and tracks payments. FSM software handles the whole job: scheduling, dispatch, job notes, invoicing, and payments. For most plumbing businesses with more than one tech, FSM software is the better buy.

Is ServiceTitan worth the cost for a plumbing company?

Only if you have 10+ techs and need enterprise-level dispatch, CRM, and reporting. At $245, $398 per tech per month, a 5-tech shop pays $1,225, $1,990/month. For smaller shops, Jobber or Housecall Pro give you 80% of the value at a fraction of the cost.

How do I stop missing calls and losing plumbing jobs after hours?

Your invoicing software won’t fix that. A tool like ServiceAgent adds a 24/7 AI voice agent for service businesses on top of your existing stack. It answers calls, books jobs, and follows up on unpaid invoices automatically, even at 11pm.

What should plumbing invoice software actually include?

At minimum: professional invoice templates, online payment collection, automated reminders for unpaid invoices, and QuickBooks or accounting sync. Ideally also: estimate-to-invoice conversion, job history per customer, and mobile access for techs in the field.

Is there free plumbing invoice software?

Most tools offer free trials, not free plans. ServiceAgent is the exception with a free platform (you pay per call handled and per payment processed). For pure invoicing, Wave offers a free tier but lacks plumbing-specific features.
