Plumbing computer software — the full stack a plumbing business needs in 2026
Published
Plumbing computer software spans four categories a modern plumbing business needs: field service management (Jobber, Housecall Pro, Workiz, ServiceTitan for scheduling, dispatch, invoicing), accounting (QuickBooks Online or Desktop), design and sizing (Revit MEP, AutoCAD MEP, h2x Engineering for plumbers doing design-build), and estimating (flat-rate pricing tools like Profit Rhino or built-in pricebooks in FSM tools). Typical all-in annual software cost runs $1,500–$3,600/year for a solo plumber, $4,200–$9,500/year for a 5-tech shop, and $18,000–$45,000/year for a 15-tech operation (verified April 2026 via vendor published pricing at getjobber.com, housecallpro.com, workiz.com, quickbooks.intuit.com, and h2xengineering.com). The specific combination depends on whether the business is service-focused (mostly FSM), design-build (add CAD), or commercial project-focused (add estimating and project management).
This guide walks through the software categories a plumbing business needs, typical costs at each tier, and the realistic stack for solo, 5-tech, and 15-tech operations.
The four software categories
1. Field service management (FSM)
The core software a service plumbing shop runs on. Handles scheduling, dispatch, mobile tech app, estimating, invoicing, and payment collection.
Typical tools (verified April 2026 pricing):
| Tool | Starting price | Users included | Best fit |
|---|---|---|---|
| Jobber Core | $39/mo | 1 user | Solo plumbers |
| Jobber Connect | $169/mo | 5 users | Small shops |
| Jobber Grow | $199/mo | 15 users | Growth-stage |
| Housecall Pro Basic | $59/mo | 1 user | Solo |
| Housecall Pro Essentials | $149/mo | 5 users | Small shops |
| Housecall Pro MAX | $299/mo + $35/user | Scales | Mid-size |
| Workiz Lite | Free | Up to 2 users | Solo / small |
| Workiz Standard | $229/mo | 5 users | Dispatch-heavy |
| ServiceTitan | ~$398/tech/mo (quote) | Per-tech | 15+ techs |
| FieldEdge | ~$100–$200/user/mo (quote) | Per-user | 8–30 techs |
See our plumbing software buyer's guide for a detailed comparison of FSM tools for plumbing shops.
2. Accounting software
Every plumbing business needs accounting. The default is QuickBooks, either Online or Desktop.
QuickBooks Online plans (April 2026):
| Plan | Monthly (annual billing) | Users | Fit |
|---|---|---|---|
| Simple Start | $30/mo | 1 | Solo |
| Essentials | $60/mo | 3 | Small shops |
| Plus | $90/mo | 5 | Most plumbing shops |
| Advanced | $200/mo | 25 | Larger operations |
QuickBooks Desktop Pro: $549.99/year single-user, $1,049.99/year 3-user; more specialized accounting but being sunset in favor of QBO. Many older plumbing shops still prefer Desktop for more complex class and job costing.
Alternatives: Xero runs $20–$80/mo; FreshBooks $20–$65/mo; Wave is free with per-transaction fees on payment processing.
For most plumbing shops, QuickBooks Online Plus at $90/month is the practical default. See QuickBooks integration for service businesses for which FSM tools integrate cleanly with QBO.
3. Design and pipe sizing software
Plumbing shops doing new construction, design-build, or commercial piping need design tools beyond Manual load calculations.
Major options:
- Revit MEP (Autodesk AEC Collection) — $3,220/year per seat as of April 2026. 3D BIM modeling for mechanical, plumbing, and electrical. Industry standard for commercial plumbing design.
- AutoCAD MEP — available within Autodesk's AEC Collection. 2D/3D pipe routing with plumbing libraries.
- h2x Engineering — standalone plumbing design tool that exports to Revit and AutoCAD. Web-based. Faster than Revit for small-to-mid projects. Pricing: $120–$380/month depending on modules (verified April 2026 via h2xengineering.com).
- HidraSoftware Plugin for Revit — plumbing design plugin with automatic pipe sizing (by velocity or unitary head loss). Paid plugin on top of Revit license.
- Trimble SysQue — Revit plugin for spool-sheet pre-fabrication. Used by larger plumbing shops doing pipe pre-fab.
For residential service plumbing, design software is rarely needed — most jobs are repair, replace, or small additions that don't require engineered drawings.
For design-build plumbing (whole-house repipes, new construction, commercial projects), Revit MEP or h2x is typically required — either in-house or through an MEP engineering partner.
4. Estimating and pricebook tools
Flat-rate pricing requires a pricebook — a library of standard jobs with standard prices.
Options:
- Profit Rhino — industry-standard plumbing pricebook with 1,500+ pre-priced line items. $150–$300/month depending on plan. Integrates with most FSM tools.
- PriceBook Pro — similar category, competing pricing. Integrates with ServiceTitan, FieldEdge, others.
- Built-in FSM pricebook — Jobber, Housecall Pro, Workiz, and ServiceTitan all include basic pricebook tools at mid-tier and above. Functional for standard work; less comprehensive than Profit Rhino for niche jobs.
- Custom spreadsheet — free, time-intensive to build (40–80 hours), works well at solo scale.
Most plumbing shops on flat-rate pricing end up using Profit Rhino or a similar tool for their core 200–400 standard jobs, with the FSM's built-in pricebook for simpler categories.
Realistic stacks by shop size
Solo plumber ($0–$200K revenue)
| Category | Tool | Monthly cost |
|---|---|---|
| FSM | Jobber Core or Workiz Lite (free) | $0–$39 |
| Accounting | QuickBooks Online Simple Start | $30 |
| Pricebook | FSM built-in | Included |
| Design | Not needed | — |
| Communications | Google Workspace Starter | $7 |
| Total | $37–$76/mo ($444–$912/year) |
Adding Profit Rhino ($150/mo) if transitioning to formal flat-rate takes the solo total to $225/mo.
3-tech residential plumbing shop
| Category | Tool | Monthly cost |
|---|---|---|
| FSM | Jobber Connect or Housecall Pro Essentials | $149–$169 |
| Accounting | QuickBooks Online Plus | $90 |
| Pricebook | Profit Rhino | $150 |
| Payment processing | via FSM | 2.6–3.0% |
| Communications | Google Workspace Starter × 3 | $21 |
| Total | $410–$430/mo subscription |
Plus payment processing at ~2.7% on revenue. For $350K annual revenue processing 75% via card, add ~$7,100/year in fees. Total software+processing: $12,000–$13,000/year.
10-tech residential + commercial plumbing shop
| Category | Tool | Monthly cost |
|---|---|---|
| FSM | Housecall Pro MAX ($299 + 9×$35) | $614 |
| Accounting | QuickBooks Online Plus | $90 |
| Pricebook | Profit Rhino | $250 |
| Design (light commercial) | h2x Engineering | $180 |
| Photo docs | CompanyCam Pro | $99 |
| Communications | Google Workspace × 8 | $56 |
| Total | $1,289/mo subscription |
Plus payment processing at 2.8%. For $1.4M annual revenue, add ~$28,000/year in fees. Total software+processing: $43,000–$48,000/year.
15-tech commercial-leaning plumbing shop
At this size, ServiceTitan or FieldEdge becomes the practical FSM; design work moves to Revit MEP. Typical stack:
| Category | Tool | Monthly cost |
|---|---|---|
| FSM | ServiceTitan ($398/tech × 15) | $5,970 |
| Accounting | QuickBooks Desktop Enterprise or Online Advanced | $200 |
| Pricebook | Pricebook Pro (built into ServiceTitan) | Included |
| Design | Revit MEP AEC Collection × 2 | $537 |
| Photo docs | CompanyCam Pro | $290 |
| Communications | Google Workspace Business × 15 | $195 |
| Total | $7,192/mo subscription |
Plus processing, integrations, add-ons. Typical all-in: $100,000+/year.
How the categories interconnect
The critical question when stacking plumbing software: do the pieces talk to each other?
FSM ↔ Accounting. Every modern FSM tool integrates with QuickBooks Online. Depth varies — see QuickBooks integration for service businesses for the deep comparison. Bad integration wastes 2–6 hours/week on reconciliation.
FSM ↔ Pricebook. Profit Rhino, PriceBook Pro, and similar tools integrate natively with most FSM platforms. The tech selects a job from the pricebook on their mobile device; the estimate auto-generates in the FSM.
FSM ↔ Payment processing. Typically integrated via the FSM's native processor (HCP Payments, Jobber Payments, ServiceTitan Payments). Alternatively, external processors (Stripe, Square) plug in but with less seamless experience.
Design software ↔ FSM. No major native integration in 2026. Design output (plans, bid quantities) is typically exported to PDF and attached to FSM jobs.
Accounting ↔ Design. No integration. Plumbing design software outputs drawings and material takeoffs; accounting tracks dollars. These live separately.
Common stack mistakes
1. Paying for QuickBooks Desktop when you should use Online. Unless you have a specific Desktop-only workflow, QBO integrates with FSM tools far more cleanly. Migration pain is 10–30 hours; ongoing benefit is 2–4 hours/week saved.
2. Running two FSM tools simultaneously. Some shops keep an old tool "just in case" while piloting a new one. Data gets stale in one; techs get confused which to use. Commit to one FSM tool; migrate fully.
3. Skipping the pricebook. Hand-pricing every job burns 15–30 minutes per estimate that flat-rate pricing automates. For shops doing 500+ jobs/year, a Profit Rhino subscription saves 125+ hours/year of tech and office time.
4. Over-buying design software for a service shop. Revit MEP is overkill for a residential service plumbing operation. Save the $3K/year and use free pipe sizing calculators (h2x offers free tools, as does the IAPMO plumbing handbook) when occasional sizing is needed.
5. Under-paying for processing. Negotiating payment processing rates is worth the 30 minutes. A 0.3% reduction on $1M annual card volume saves $3,000/year. Most processors will negotiate at $500K+ volume.
6. Buying communications (email) from the FSM vendor. Some FSM tools offer branded email or CRM-linked email. Google Workspace at $7/user/mo does this more flexibly with fewer vendor-lock issues.
FAQ
What's the cheapest plumbing software stack?
Solo plumber: Workiz Lite (free FSM) + QuickBooks Online Simple Start ($30/mo) + manual pricebook = $30/mo total. Functional for $0–$100K revenue. Upgrade when growth demands.
Do plumbers need design software?
Only plumbers doing new construction, design-build, or commercial piping work. Residential service plumbers rarely need anything beyond the FSM tool's built-in diagramming.
What plumbing design software is cheapest?
h2x Engineering at $120–$380/month is the cheapest legitimate pipe sizing + design tool in 2026 for small plumbing design-build shops. Revit MEP's AEC Collection at $3,220/year is the BIM-standard but priced for larger operations.
Can I run a plumbing business on just QuickBooks?
For invoicing only, yes. But you'll miss scheduling, dispatch, mobile tech workflows, and customer history. Most shops that start "just on QuickBooks" switch to an FSM tool within 12 months once growth pain compounds.
How do I estimate plumbing jobs in software?
Two approaches: flat-rate pricebook (Profit Rhino, PriceBook Pro, or FSM built-in) where jobs have pre-priced templates, or time-and-material estimates where the tech enters hours × rate + materials. Flat-rate produces higher close rates and more consistent margin. See our flat-rate vs time-and-material pricing guide.
What's the best plumbing software for small shops?
For 1–5 tech residential service, Jobber or Housecall Pro are the default candidates. See our plumbing software buyer's guide for the detailed comparison.
Do I need QuickBooks Desktop or Online?
Online for most shops in 2026. Desktop still matters for shops with established Desktop-specific workflows or those using FieldEdge which has deeper Desktop integration. Default to Online unless a specific Desktop requirement exists.

Next step for plumbing businesses evaluating their stack: audit your current software spend against the stacks outlined above. Solo shops spending more than $150/month on software are usually over-buying; 5-tech shops spending less than $400/month are usually under-buying (missing the FSM tier that supports growth). Re-evaluate at the milestone transitions (first employee, 5 techs, 10 techs) rather than annually.
