The Direct Answer
Most small plumbing businesses manage customers through one of four stages:
- Stage 1 (0–10 jobs/month): Phone contacts app + texts + memory
- Stage 2 (10–30 jobs/month): Google Sheets or a notes app for tracking
- Stage 3 (30–75 jobs/month): A dedicated CRM — most commonly Kordless CRM (free) or HubSpot Free
- Stage 4 (75+ jobs/month or multiple trucks): Field service management software — Housecall Pro, Jobber, or ServiceTitan
The right tool depends entirely on where you are, not where you want to be someday.
When a plumber asks "what software should I use to manage customers," they usually mean one of three things:
- How do I stop forgetting to call leads back?
- How do I know who owes me money and who I need to follow up with?
- How do I keep track of what each customer had done?
These are different problems. Here's what actually solves each one.
What Most Small Plumbing Businesses Actually Use
The Honest Starting Point: Nothing Formal
Most plumbers under 20 jobs per month manage customers through their phone's contacts app, iMessage threads, and their own memory. It works until it doesn't — and it stops working around the time a $2,500 job lead texts at 9pm on a Thursday and you forget to respond because Friday gets busy.
The missed follow-up isn't a memory problem. It's a system problem.
The First Upgrade: A Spreadsheet
The most common first step is a Google Sheet with columns like: Name, Phone, Address, Job Type, Date, Status, Notes. Simple, free, and a real improvement over nothing.
When a spreadsheet is fine:
- You handle every job yourself
- You have under 30 active customers at any time
- You're comfortable opening a laptop between jobs
When it breaks down:
- You can't set follow-up reminders
- You can't see your pipeline at a glance on your phone
- Leads fall through the cracks when the sheet gets long
Tools Small Plumbing Businesses Use
Kordless CRM — Best for Solo Operators and Small Crews
Cost: Free forever (no credit card required)
Kordless CRM is the most common upgrade from a spreadsheet for small plumbing operations. It's built specifically for local service businesses — not adapted from a sales tool designed for software companies.
What plumbers use it for:
- Tracking every lead from first contact to completed job
- Setting follow-up reminders ("Call Mike back about the water heater in 2 weeks")
- Seeing the full job history for a repeat customer when they call
- A simple pipeline: New Lead → Quoted → Scheduled → Completed → Follow-Up
The mobile-first design matters. You're not going to open a laptop after a drain job at 4pm. Kordless CRM updates in 30 seconds on your phone.
Biggest advantage over a spreadsheet: Reminders. When you set a follow-up for two weeks from now, it surfaces on that day. Closed jobs that could have been open jobs don't happen.
What it doesn't do: Kordless CRM doesn't handle dispatching, invoicing, or route optimization. It's a lead-and-customer management tool, not a full field service platform. If you need those features, see Housecall Pro below.
HubSpot CRM Free — Most Recognizable Name
Cost: Free (with limits on marketing features)
HubSpot's free CRM is widely used and well-documented. Plumbers who've heard of HubSpot through other business channels often start here.
What works: Contact timelines, email tracking, basic pipeline management.
What doesn't work well for plumbing:
- The interface is designed around software sales cycles, not job-based service work
- Setting it up properly takes 2–4 hours — most plumbers start it, get frustrated, and abandon it
- Key automation features are behind paid tiers ($20+/user/month)
Housecall Pro — Best for Multiple Trucks
Cost: $59–$149/month
Housecall Pro is purpose-built for field service businesses. When a plumbing operation grows past one truck, it becomes genuinely useful: scheduling, dispatching, invoicing, customer communication, and review requests all in one platform.
What plumbers use it for:
- Dispatching technicians to jobs
- Customer self-scheduling
- Estimates and invoices
- Automated review requests after job completion
When it makes sense: You have 2+ technicians, 50+ jobs per month, and need to coordinate logistics. The $59–$149/month cost is easy to justify at that scale.
When it's overkill: If you're a solo plumber doing 20–30 jobs a month, Housecall Pro is more software than you need. Most of what you'd pay for, you'd never use.
Jobber — Best for Recurring Service Contracts
Cost: $49–$129/month
Jobber competes directly with Housecall Pro and is particularly well-suited for plumbing businesses that sell maintenance contracts or service agreements. The recurring job scheduling and contract management features are strong.
Key difference from Housecall Pro: Jobber has better recurring job templates. If you sell annual drain maintenance packages, Jobber handles the scheduling and renewal reminders cleanly.
ServiceTitan — Enterprise-Grade (Skip This Until You're Bigger)
Cost: $200–$600+/month
ServiceTitan is the dominant platform for large plumbing franchises and operations with 10+ trucks. It's powerful, expensive, and has a steep learning curve.
Honest take: If you're reading this article, ServiceTitan is not for you yet. It requires dedicated staff to manage and is priced accordingly. File it away for a future version of your business.
What to Use Based on Where You Are
| Business Size | Best Option | Why |
|---|---|---|
| 1 plumber, under 20 jobs/month | Kordless CRM (free) | Zero cost, mobile-first, reminds you to follow up |
| 1–2 plumbers, 20–50 jobs/month | Kordless CRM + Kordless Chat | Add AI lead capture so you stop missing after-hours leads |
| 2–5 plumbers, 50+ jobs/month | Housecall Pro or Jobber | Need dispatching and invoicing, not just CRM |
| 5+ trucks, franchise scale | ServiceTitan | Built for the complexity |
The Problem Nobody Talks About: Leads That Disappear Before the Job
A lot of plumbing businesses are solid at tracking jobs once they're booked. The problem is the leads that never get booked — because someone messaged at 10pm, you saw it the next morning, and they'd already called someone else.
Kordless Chat handles those. It's an AI assistant on your website that responds immediately, qualifies the lead (Is this an emergency? What's the issue? Are you in our service area?), and books the job on your calendar — without you picking up your phone.
The CRM and the chat tool together solve both sides of the problem: losing leads before they become customers, and losing customers because you forgot to follow up.
Frequently Asked Questions
Do I need software if I only have a few jobs per week? A CRM helps most starting from around 10 active leads or customers at a time. Before that, your phone contacts app is probably fine. After that, you're relying on memory in a way that costs you money.
Can I use Kordless CRM alongside Housecall Pro or Jobber? Yes. Kordless CRM is most useful in the pre-booking stage — tracking leads and follow-ups. Field service tools handle the post-booking operational side. They serve different stages and can coexist.
What do most plumbers actually use on their phone on a job site? Most use their phone's native contacts plus text threads. The next most common is Housecall Pro's mobile app for plumbers already on the platform. Kordless CRM's mobile interface was designed specifically for this use case — quick updates between jobs.
How long does it take to set up Kordless CRM? About 20 minutes to import your existing contacts and set up your pipeline stages. It's designed to be usable on day one without configuration complexity.
