What is the best plumbing estimating software?

For a small service plumbing shop, the best estimating software prices from your own costs, keeps your rates in a pricebook and lets the customer approve from their phone. Swivl's Starter plan does that for $0 a month with unlimited users. Housecall Pro and Jobber cost $189 to $199 a month for a 4-user shop, and ServiceTitan prices by request.

I ran a plumbing company before I built Swivl, and we ran into plenty of jobs where the estimate was way off. Usually we had a rosy picture of the hours, or we priced a job we didn't understand.

So when you shop for plumbing estimating software, look for three things. It should start from what the job costs you, keep your labor rates and parts in one place, and get the estimate in front of the customer while you're still in the driveway. The tools in this post all handle estimates. The difference is mostly price, and how many plumbers you pay for.

What kind of plumbing estimates do you write?

Plumbing estimating covers two different jobs. Service and repair work is a water heater swap, a slab leak, a sewer line, a fixture change. You price it on site or the same day, and the customer decides fast. New construction and big remodels get bid off plans, with a takeoff of every fitting and foot of pipe.

This post is about the first kind. If most of your revenue comes from bidding new construction off blueprints, you want dedicated takeoff software, and that's a separate category. If you're a one to five truck service shop, you need estimates you can build quickly, price consistently and send from the truck.

Should a plumber use flat-rate or cost-plus pricing?

Most service plumbers use flat rate for the work they do every week and cost-plus for everything else. Flat rate means one price for a task, like a toilet rebuild or a disposal swap, no matter how long it takes. The customer likes knowing the number up front, and your plumber doesn't have to sell the hours.

Matt Navin runs AAA Rooter, a drain company his grandfather started in Berlin, Connecticut. On his Swivl Sessions episode he explains why they charge $400 to snake a sewer line. A flat price only works when you know what the task costs you and you've done it enough times to trust the number.

Cost-plus is for the jobs that don't repeat. You add up labor, materials, equipment and anything you sub out, then put your markup on top. It's slower, and it's the safest way to price work you haven't done fifty times. You can read how one shop made the switch in how cost-plus pricing changed a plumbing business.

A short Swivl guide, about two and a half minutes long, on setting up a pricebook and choosing between flat-rate pricing and cost-plus pricing for the work you sell.

Whichever way you price, the rates belong in a pricebook, so every plumber quotes the same water heater the same way. The pricebook is free on every Swivl plan.

What did a lift station job teach me about estimating?

There was one job at the plumbing company that was grotesque, and we had no idea what we were getting into. It was a giant lift station under a parking lot, full of gunk. We figured we'd rent one of those big transfer pumps, mix it up and pump it out.

We couldn't. We had to pull a lot of it out by hand, and we sent people down there with buckets to shovel it out. It was horrible, and it took many times the hours we'd planned.

We had no business doing that job, because we didn't know what the job actually was. The lesson I took from it: if you can't estimate what it'll cost you, don't take the job. Good estimating software makes you write down the cost of every part of the job, so the gaps show up before you sign.

Aaron Cleveland built ACE's Plumbing in Hilton Head, South Carolina, to $3 million in three years. On his Swivl Sessions episode he shared a rule he picked up from a master plumber, and it applies to estimates as much as to the work.

Can AI write a plumbing estimate?

It can write the first draft. In Swivl you describe the job or add photos, and the AI Estimator builds the line items from your own labor rates, material costs and markups. It splits the cost into labor, materials, equipment, vehicle, subcontractor and other, and each category carries its own markup.

A walkthrough of how Swivl builds an estimate for a 50-gallon gas water heater replacement. The AI estimator first estimates your cost in six categories (labor, materials, tools and equipment, vehicles, subcontractors and other), then adds your markup per category to get the customer price. It also shows where default markups live in the pricebook. Jump to cost + markup = price at 2:06.

Check the hours, the drive time and the margin before you send it. The AI only knows what you describe and what's in the photos. It has never been down in a lift station, and it doesn't know which plumber you're sending.

The AI Estimator costs about 60 credits per estimate, at the same rate on every plan. A short job costs less, and one with a lot of photos and a long materials list costs more. Starter includes 250 credits a month, which is about 4 AI estimates. Growth is $49 a month with 1,500 credits, about 25 AI estimates. Writing an estimate yourself never costs credits.

What should a plumbing estimate show the customer?

A homeowner with water on the floor wants to know three things: what you'll do, what it costs and when you can start. Put the work in plain words, show the price, and let them approve from their phone so you can start while you're still there.

Matt Navin's crew has a habit that does more for trust than a fancy proposal.

In Swivl, the estimate lives inside the job, next to the visits, photos, tasks and the invoice. When the customer approves it, nobody retypes the work onto an invoice later, and you can compare what you estimated with what the job actually cost.

What does plumbing estimating software cost for a 4-plumber shop?

Say you have four plumbers who all write or present estimates. Here's what each tool charges on monthly billing, from their pricing pages on October 17, 2026:

• Swivl: Starter is $0 a month and Growth is $49, both with unlimited users and unlimited estimates you write yourself. Monthly, no contract. AI estimates use credits. (pricing, checked October 17, 2026)
• Housecall Pro: Essentials is $189 a month for 5 users and includes a visual price book. Basic is $79 a month for 1 user. It has no long-term contract. (pricing, checked October 17, 2026)
• Jobber: Connect is $199 a month for 5 users and automates quote follow-ups. Grow is $299 for 5 users and adds optional line items for upsells. (pricing, checked October 17, 2026)
• ServiceTitan: every tier includes a pricebook and mobile estimates. Pricing is per technician and by request. (pricing, checked October 17, 2026)

Each of them does something well. Housecall Pro has a visual price book on Essentials and a sales proposal tool on Max for showing options side by side. Jobber follows up on unanswered quotes for you, and Grow adds optional line items for upsells. ServiceTitan puts call booking, payroll and a pricebook on every tier, which suits a larger shop with a full office.

Which plumbing estimating software should you pick?

If you run a big shop with a sales team presenting options on every call, ServiceTitan or a higher Housecall Pro or Jobber plan may be worth the money. If you're one to five trucks and the owner still writes most of the estimates, start free and pay only when you use the AI. Put your real costs in the pricebook first, because that matters more than which app you pick.
