Tech for Plumbers: The Software Stack That Actually Makes Money

Your techs are in trucks 10 hours a day, invoices 3 days late, the spouse doing books at midnight. The right stack fixes all three. The stack in order, what each piece costs, and when to buy versus build. One weekend of setup ends the midnight bookkeeping — if you buy in the right order. Also see Plumbers, AI for Plumbers, and Payments for Plumbers.

The stack, in the order that matters

Buy in this order — each layer pays for the next:

• 1. Dispatch and scheduling — the operating system. Quotes, calendar, dispatch, invoices, payments in one app.
• 2. The phone system — the front door. A business line that rings the right person, records calls, texts customers. Your personal cell is not a phone system.
• 3. Accounting — the scoreboard. QuickBooks Online or Xero, synced to dispatch. Midnight bookkeeping ends when data stops being retyped.
• 4. Photo documentation — the proof layer. CompanyCam (Core $63/mo for one user, Crew $119/mo for three, annual billing): every photo timestamped and GPS-pinned to the job address. The corroded anode-rod photo sells the $1,800 water heater; the before-and-after of the sewer line ends the chargeback. Your dispatch app's built-in photos work at 1–2 trucks; past that, the dedicated tool earns its keep.
• 5. Marketing presence — the lead pipe. Google Business Profile (free), a simple website, Google Local Services Ads — in that order. A $10,000 website before 50 reviews is jewelry on a work truck.

The big three field-service platforms, honestly compared

Prices checked October 2026; annual billing shown first.

• Housecall Pro — Basic $59/mo ($79 monthly, 1 user); Essentials $149 ($189, 5 users); MAX $299 ($329, 8 users). Plumbing/HVAC package costs more. Cards from 2.59%, bank payments 1%. Best for: 1-to-8-truck shops wanting everything in one app, with Spanish support. Skip if: past ~20 trucks. Catch: proposals, GPS, and the pricebook are add-ons; recurring plans need MAX.
• Jobber — Core $49/mo ($29 annual, 1 user) to Plus $699/mo for 15 users; extra users $29/mo; 14-day trial; cards 2.9% + $0.30. Best for: quote-heavy shops wanting deep QuickBooks sync. Skip if: you want everything included.
• ServiceTitan — ~$245–$500 per tech per month, $5,000–$50,000 implementation, 12-month minimum, no published prices. Best for: 20-plus-truck operations with an office manager. Skip if: under 10 trucks.

Two notes the brochures skip. Housecall Pro has Wisetack financing built in — the "pay over time" button on invoices $500–$65,000 — which matters more than any feature comparison once you're quoting $4,000 repipes. And ServiceTitan's headline price is the floor: Marketing Pro, Pricebook Pro, and the other add-ons stack fast, which is why implementation quotes range from $5,000 to $50,000. Whatever you pick, run 20 real jobs through the trial before you port the number — migrations are where shops go to die.

Bargain corner: Workiz free tier (2 users), paid from ~$200/mo.

Buy vs. build: when custom software makes sense

For 95% of shops, the answer is buy. Off-the-shelf wins until ~15–20 trucks.

Build when the software is the advantage:

• A customer portal where property managers see every unit's history, approve work, and pay — the thing that wins the 200-unit contract.
• A quoting engine tied to your exact flat-rate pricebook, so every tech quotes identically.
• Dispatch logic your platform cannot express — skill-based routing across 30 techs.

A real build starts at $25,000–$75,000 plus 15–20% a year in maintenance. Nearshore senior engineers cut that roughly in half — Nova is an AWS partner offering a free first consultation. If you cannot name the revenue it unlocks, you do not need it.

Most "custom" needs die at the integration layer: off-the-shelf dispatch plus Zapier or Make covers automated follow-ups, review requests, and QuickBooks sync for under $200/mo. Build only when the software wins the contract — and if you can't name the contract, you don't need the build.

What the whole stack costs: 1 truck, 5 trucks, 15 trucks

Monthly totals, annual billing, before card fees:

• 1 truck: Housecall Pro Basic $59 + QuickBooks Simple Start $38 + business line ~$20 = ~$120/mo.
• 5 trucks: Essentials $149 + add-ons ~$100 + QuickBooks Essentials $85 + phone ~$199 + AI answering ~$150 + CompanyCam Crew $119 + NiceJob $75 = ~$880/mo.
• 15 trucks: the ServiceTitan decision. ~$350/tech = ~$5,250/mo ($63,000/yr) plus implementation — or Housecall Pro MAX / Jobber Plus at roughly a tenth.

Software should run 1–2% of revenue — a $1.5M shop at $880/month is at 0.7%. The expensive mistake is never the subscription; it is the shop running on texts, memory, and a spouse at midnight.

Marketing spend sits outside the stack: Google Local Services Ads run about $57 per plumbing lead in 2026 benchmarks (emergency calls $40–$80), and you can dispute invalid leads for credit. At a ~44% book rate that's roughly $128 per booked job — know the number before you raise the weekly budget.

Where shops waste money

• ServiceTitan at 3 trucks — a reporting suite for the office manager you do not have.
• Six apps that do not talk — every handoff between them is a dropped ball.
• Seats nobody uses — audit twice a year; the $29/mo seat for the tech who quit in March adds up.
• "Free" software with strings — if the price is zero, you are the product, or your data is locked in. Check the export story first.
• Building custom too early — a $40,000 portal for a 4-truck shop is a hobby, not an investment.
• The AI add-on nobody turned on — dispatch and review apps now upsell AI features that bill monthly while nobody configures them. Audit: if no one's trained it, cancel it.
• Marketing software before the reviews exist — Local Services Ads with 12 reviews is paying to advertise that nobody trusts you yet.

FAQ

Housecall Pro or Jobber? One app for scheduling, payments, and texts: Housecall Pro. Quote-heavy with QuickBooks sync: Jobber. Run 20 real jobs through each free trial first.

Do I need to leave my personal cell? Yes. Call recording ends every "he said the price was X" dispute, and AI answers without touching your personal number.

When does ServiceTitan make sense? Around 15–20 trucks, with an office manager and real reporting needs. Before that, a Ferrari for grocery runs.

Should techs use personal phones? No. Customer addresses, photos, and text threads live on that device — when the tech quits, your customer data walks out with him. Company phones or a device-management policy; the app is the office either way.

iPads or phones for techs? The phones they already carry, in a rugged case. A separate tablet is one more thing to charge, lose, and never update.

When do I hire an office manager instead of more software? Software first, until ~8–10 trucks. Hire the office manager when dispatch, books, and follow-ups exceed one person's day — software delays that hire by years.

This month: pick the dispatch platform, port the number, connect QuickBooks, turn on follow-ups. One weekend ends the midnight bookkeeping. AI answering, custom portals, fancy reporting — all after the foundation. Then measure: missed calls, days-to-paid, review count. The stack is working when all three move.
