What makes plumbing software different
Plumbing is two businesses under one roof: emergency service that has to move fast, and planned replacements that have to sell well. Generic job software tends to handle the planned side and struggle with the emergency side. A burst supply line at 10 p.m. needs to go from a phone call to a dispatched tech in minutes, with the address, the customer's history and the after-hours rate already on the job. If the on-call tech is digging through texts to find the address, the software isn't doing its job.
Parts are the second big difference. A plumbing van carries a lot of stock: fittings, valves, cartridges, wax rings, water heater parts, sometimes a spare heater. Most shops leak margin through parts that went into a job and never made it onto the invoice. Software that only knows a price list can't tell you what's on truck 3 or what to pick up at the supply house tomorrow morning. If your stock per van is significant, inventory by truck should be on your must-have list, and it's the feature that most separates the plumbing-ready tools from the general ones.
Then there's documentation. Drain and sewer camera footage is how you justify a sewer line replacement to a skeptical homeowner (or their spouse, who wasn't home). Photos of a corroded water heater, a failed PRV or a cracked cleanout make estimates easier to approve and warranty disputes easier to win. The software has to attach photos and video to jobs and estimates, let the homeowner see them, and keep them findable a year later when that customer calls back.
Finally, plumbing estimates repeat. Water heater swaps, toilet replacements, disposal installs, PRVs, softeners. Every one of them can be a saved package with options and the code-required extras built in, so the newest tech quotes it the same way the owner would.
How to choose by shop size
One truck
You need to answer the phone, quote on the spot, get paid before you leave and not lose track of callbacks. Housecall Pro Basic ($59/mo billed annually) or Jobber Core ($29/mo billed annually) covers it. ServiceM8 is worth a look if you're on an iPhone: its free plan includes 30 jobs a month and Starter is $29/mo for 50 jobs with unlimited users, though owners report Android support is weaker. Don't worry about inventory software yet. A weekly count of your van on a clipboard is fine at this size.
Two to five trucks
Now you have an on-call rotation, somebody answering phones, and parts going out the door you can't see. Housecall Pro Essentials at $149/mo billed annually (up to 5 users) handles dispatch, estimates and payments for most shops this size. If you're mostly emergency work and spend real money on ads, get a Workiz quote and compare what call tracking would show you. Start thinking about inventory here: if you can't say within a few hundred dollars what's on each truck, that's costing you.
Six to fifteen-plus trucks
This is where per-user pricing starts to hurt and inventory becomes a must. Service Fusion's flat pricing with unlimited users (Plus at $325/mo billed annually, with inventory included) looks good next to per-seat plans at 12 or more users. Housecall Pro MAX with 12 users is about $439/mo. ServiceTitan comes into play for shops with a call center and a dedicated replacement sales process, at third-party estimates of $245 to $500 per tech per month (not published by the vendor).

Card processing is often bigger than the subscription. Say you do $50,000 a month in card payments. At Jobber's 2.9% + 30¢ that's $1,450 plus 30 cents per payment; Housecall Pro lists card rates from 2.59%, at least $1,295. On a hypothetical $6,000 sewer line replacement, a card payment at 2.9% costs $174 and an ACH bank payment at 1% costs $60. Offering ACH or financing on big jobs is worth setting up on day one.
Watch job-based pricing if you do lots of small calls. ServiceM8's plans cap jobs per month (Growing is $79/mo for 150 jobs), so a busy drain-cleaning shop can outgrow a tier fast.
Common mistakes when switching plumbing software
Going live during a freeze. Frozen and burst pipes bury plumbing shops in January in much of the country, and spring thaw brings its own wave. Pick a slower stretch for your area, and give yourself two weeks of overlap where the old system stays readable.
Leaving photos and camera footage behind. Most exports move customers, jobs and invoices. Attachments often don't come along, or come as a giant unsorted zip file. Ask how attachments migrate, and download anything you might need for warranty or dispute purposes before you cancel the old account.
Turning on inventory without a starting count. Inventory software is only as good as the first count. Count every truck and the shop shelf on the same day you go live, and set a weekly restock routine so counts stay honest.
Rebuilding after-hours pricing from memory. Write down every trip charge, after-hours rate, weekend rate and holiday rate you charge today, then build them as separate items in the new system. Shops that skip this end up undercharging on-call work for months.
Forgetting the on-call tech's phone. Test the after-hours call flow end to end before go-live: customer calls, call reaches the on-call tech, job gets created, tech gets directions and the right rate. Do it on a Tuesday afternoon, not at midnight with a real flood.
Paying for a call center tool you won't staff. Big platforms sell call booking and marketing dashboards that assume a CSR is sitting there. If your office is one person who also does payroll, buy the simpler tool and spend the difference on a good answering service.
