Running a Plumbing Company Shouldn't Mean This
If any of these hit home, you're not alone — and there's a fix that doesn't cost a fortune.
2 AM Burst Pipe Chaos
The phone rings at 2 AM. Sewer backup. You're scrolling through contacts trying to remember who's on call, then playing phone tag until someone picks up. Meanwhile, the customer's basement is filling with water.
With FSM Navigator®:
Flag it as urgent and the assigned plumber gets an instant push notification that opens the job. Dispatch in under 30 seconds — not 30 minutes of texting (see the plumbing benchmark).
Return Trips Kill Your Margins
Your tech drives 40 minutes to a job, opens the van, and realizes he's out of ¾" SharkBite fittings. Another 80 minutes round-trip to the supply house. That job just went from profitable to break-even.
With FSM Navigator®:
Track van stock. Low-stock alerts fire before your plumber leaves for the day. Know what's on every truck so the right parts are already there.
No Service History When You Show Up
The customer says "your guy was here last year." Your tech has no idea what was done — pipe material, access points, where the main shutoff is. So he spends 20 minutes figuring out what someone already figured out once.
With FSM Navigator®:
Every past visit, note, photo, and part used is on your tech's phone. Pull up the property, see exactly what happened last time, and get to work.
Paper Tickets + Water = Gone
Carbon-copy work orders stuffed in a wet van. Half are illegible, a quarter are missing, and your office person spends Friday afternoon trying to piece together enough info to invoice. Sound about right?
With FSM Navigator®:
Digital work orders with photos, timestamps, and notes. Everything syncs to the office the second the job closes. No lost tickets, no guessing.
One App from First Call to Renewals
A plumbing shop usually runs on a phone, a quote template, a whiteboard, an invoicing app and a list of maintenance customers nobody calls back. FSM Navigator is one app for all of it, from 2 plumbers to 200 and beyond, with no user limit on paid plans.
- Get the customer. Customers request a drain cleaning or a water heater estimate from your online booking page, and each request waits for your approval. After the job, every customer is asked for a rating, and everyone who rates can leave you a Google review. (Pro and Enterprise)
- Win the work. Keep your flat-rate services, labor and materials in the pricebook for plumbers, then send a water heater quote with good, better and best options. The customer e-signs it and pays the deposit online, and the signed quote becomes a job at the agreed price and tax. (Pro and Enterprise)
- Do the work. Intelligent dispatch sends the right plumber to the burst pipe and reshuffles the rest of the day around it (auto-assignment on Pro and Enterprise). Job forms capture checklists and test results, and the customer signs on the plumber's phone before they leave (Pro and Enterprise). The iOS and Android app works offline on every plan.
- Get paid. Invoice from the finished job on every plan. On Pro and Enterprise, customers pay by card or bank transfer (ACH) in their portal, a paid deposit is credited to the invoice automatically, and invoices sync to QuickBooks Online.
- Keep the customer. Maintenance agreements with a service address schedule their own inspection visits, and membership plans give members their pricing and can charge the card on file automatically. (Pro and Enterprise) See plumbing maintenance agreements for how plumbing shops set them up.
- Run the business. Job profitability shows the margin on every completed job against labor, parts and mileage (Pro and Enterprise). Inventory, assets and work orders are on Enterprise.

Plumbing Scheduling That Keeps Up with Your Day
Stop dispatching by memory and gut feel. See who's available, who's closest, and who has the right skills — then assign in one click.
Visual Calendar for Every Plumber
Plumbing scheduling software that shows every plumber's day on one screen. Reassign jobs between plumbers in seconds.
Emergency Priority Dispatch
Burst pipe? Sewer backup? Mark it urgent and it jumps to the top. The nearest available plumber gets a push notification with the address and details — dispatch in under 30 seconds (benchmarked in a simulated week).
Auto-Assignment by Skill & Location
Water heater install? Sewer camera job? FSM Navigator® matches the job to the closest plumber with the right skills and lightest workload. You approve or let it ride.
After-Hours Shift Scheduling
Build weekly shift schedules that include overnight and weekend shifts. Auto-assignment only matches plumbers who are on shift, so a 2 AM call goes to someone who's working. No more scrolling your phone at midnight trying to figure out whose turn it is.
Online Booking for Planned Plumbing Work
Burst pipes call. Water heaters can book. Your booking page takes requests for planned work, like a water heater replacement or a drain cleaning, in an arrival window you set, and keeps a call-now path for emergencies. Every request waits for your approval, then becomes a scheduled visit in the same tool. Online booking is included on the Pro and Enterprise plans.
Plumbing Work Order Software That Replaces the Clipboard
Digital work orders that survive wet hands, muddy boots, and basement crawls. Every job documented, every time.
Digital Work Orders
No more carbon copies. Plumbers fill out job details on their phone — parts used, labor time, notes on the issue. It syncs to the office before they pull out of the driveway.
Before & After Photos Pro
Snap photos of the cleanout, under-slab access, corroded pipes — anything the customer or your office needs to see. They attach to the job record automatically.
Full Service History per Property and Asset
Every past visit, every note, every photo — tied to the address. Your plumber walks in knowing the pipe material, shutoff valve location, and what was done last time.
On-Site Notes & Follow-Ups
Add internal notes about access issues, tricky shutoffs, or recommended follow-ups — all attached to the job. Future techs see exactly what the last plumber documented.
Plumbing Invoicing Software That Gets You Paid the Same Day
Your plumber finishes the job. The invoice is ready to send before the van door closes. No more waiting days — or weeks — to bill.
Invoice from the Job Site
Generate invoices directly from completed jobs. Parts, labor hours, and flat-rate items are already filled in from the work order. One tap to send to the customer.
Flat-Rate & Time-and-Material Support
Bill the way your shop works. Keep flat-rate prices for common jobs (drain cleaning, water heater swap) and hourly labor side by side in your pricebook, and mix and match on the same quote. Which jobs belong on flat rate?
QuickBooks Sync
Invoices, customers, and payments flow to QuickBooks automatically. Your bookkeeper stops dealing with double-entry, and your books stay current without extra work.
Customer Portal Payments
Customers view invoices and pay online through their own portal. No more "the check is in the mail." Payments hit your account in days, not weeks.

A Plumbing Technician App That Works Where You Work
A plumber field service app built for basements, crawl spaces, and under-slab jobs — the places where cell signal doesn't reach. Your plumbers get everything they need, even offline.
Offline-First Mobile App Every plan
View job details and log notes (plus take photos on Pro) — no signal required. Everything syncs when your plumber steps back outside.
GPS Location
See where every on-duty plumber is on a live map. Send the closest qualified tech to an emergency without calling around.
Photo Documentation Pro
Snap photos of corroded pipes, cleanout access points, under-slab conditions, or completed work. They attach to the job record automatically — no texting to the office.
Full Asset Service History
Every past visit, note, photo, and part used — right on the plumber's phone. No calling the office to ask what was done at this address last year.
Automatic Mileage Tracking Pro
Every supply run and emergency call logged automatically. Mileage tracking captures the miles from En Route to Arrived, turning each trip into an IRS-ready record for tax deductions at year-end.
Track Every Fitting, Valve, and Coupling on Every Van
Know exactly what's on each truck. Stop losing money to mystery parts, surprise stockouts, and return trips to the supply house.
Van Stock Tracking
Know which fittings, valves, and supply lines are on each service van. Updated as plumbers use parts on jobs.
Barcode Scanning
Scan parts with your phone camera. No dedicated hardware needed. Inventory counts update as parts are used.
Low-Stock Alerts
Set minimum thresholds per part. Get notified before your plumber heads out with an empty van. Reorder before it becomes a return trip.
Prevent Return Trips
Every return trip to the supply house costs time and gas. With live van stock, your dispatcher can verify parts are on board before sending the plumber out.

Common Questions from Plumbing Companies
What's the best software for plumbing companies?
Look for plumbing software that fits your crew size and budget. FSM Navigator fits plumbing companies from 2 plumbers to 200 and beyond, with no user limit on paid plans. It gives you scheduling, dispatch, and invoicing starting at $0/month for up to 5 users, with van inventory tracking on the Enterprise plan. It is useful on day one, with no weeks of training or five-figure onboarding.
How much does plumbing service software cost?
FSM Navigator's Free plan covers up to 5 users with full scheduling, dispatch, and basic invoicing — forever. The Pro plan is $34.99/user/month and adds auto-assignment, recurring jobs, a KPI dashboard, QuickBooks sync, a customer portal, and customer alerts. Enterprise is $59.99/user/month for inventory management, asset management, a work order system, and REST API access. No contracts, no setup fees, cancel online anytime; access continues to the end of your paid period.
Is there a free plumbing scheduling app?
Yes. FSM Navigator's Free plan includes plumbing scheduling, dispatch and invoicing for up to 5 users, with no trial expiration. You get a schedule board that refreshes on its own, GPS location, a mobile app for your plumbers, push notifications for job updates, and basic invoicing. It's not a stripped-down demo: it's the same app, for up to 5 users.
Does FSM Navigator handle emergency and after-hours calls?
Yes. Flag a job as urgent. Build weekly shift schedules that include overnight and weekend shifts, and auto-assignment (Pro and Enterprise) only matches plumbers who are on shift when the call comes in. The assigned plumber gets an instant push notification that opens the job — no 2 AM phone tag.
Can I track parts and inventory on plumbing vans?
With the Enterprise plan's inventory module, you can track every fitting, valve, and coupling on each van. Plumbers log what they use on each job, so van stock updates on its own; each plumber sees a low-stock flag for their van in the app, and the office gets reorder alerts when company stock drops below your minimum. It's the fastest way to kill return trips to the supply house.
Does it work offline in basements and crawl spaces?
Yes. The mobile app works fully offline — plumbers can view job details, log notes, and take photos (Pro and Enterprise) with zero cell signal. Everything syncs automatically once they're back above ground. We built it this way because plumbers spend half their day in places where other apps stop working.
How fast can I set it up?
Setup takes under 5 minutes. Sign up, add your plumbers and their specialties (drain cleaning, water heaters, new construction, commercial), and start scheduling. No mandatory onboarding, no implementation fees, no waiting period. If you need help, our support team is here — but most people figure it out on their own.
Can FSM Navigator track mileage for tax deductions?
Yes. Every supply run and emergency call is logged automatically — when a plumber marks a job En Route, mileage tracking starts, and it stops on Arrived. Each trip becomes an IRS-ready record at the IRS standard rate by default (76 cents per mile since July 1, 2026) or your own rate, so you have contemporaneous, GPS-based records for tax deductions at year-end without a manual logbook. It's included on the Pro and Enterprise plans.
