What water treatment techs need from their software, from sources outside Housecall Pro and outside Nexa:
Housecall Pro covers the field work a water treatment shop runs on: scheduling and dispatching, estimates, a price book, invoicing, online payments, vehicle GPS, 'On My Way' texts, time tracking, payroll and job costing. Max adds recurring service plans and route optimization, which fit repeat filter, softener and RO service visits. Live phone and chat support comes on every plan. The gap is compliance. Licensing rules differ by state: 20 states require a Specialty License, 16 require a Plumber License, and 14 have no state-wide license or no licensing requirement in state code. Texas needs a Water Treatment Specialist license, renewed every three years with 12 hours of approved continuing education. A Class II licensee can't work on reverse osmosis or deionization equipment without a higher-class licensee supervising. Housecall Pro's feature list shows nothing for tracking each tech's license class, expiry, CE hours or renewal dates, and nothing for blocking a job a tech isn't cleared to do. The same is true of industry certifications, which also run on three-year cycles with CE and recertification fees. We haven't tested either product against a licensing audit. This read rests on published feature lists, so check a demo for any credential field.
Nexa covers the office side: invoices, estimates and proposals, recurring invoices and recurring jobs, job costing with profit per job, jobs assigned to team members with a crew view, today's stops sent to Google Maps, time tracking, a payroll CSV and full bookkeeping. Clients can pay by card through your own Stripe account. It does not track licenses, CE or certifications either. A task board could hold renewal reminders you enter by hand, but that isn't a record of who may do which job. Nexa also has no GPS or fleet tracking, dispatch board, route optimization, texting, QuickBooks sync or hosted support desk. Its payroll CSV only totals hours times rate, and stock is a simple count per product. Any automated emails, such as reminders or follow-ups, send only while Nexa is open on one of your devices. Nexa is our product, so weigh this read accordingly. It's also why we say stay wherever Housecall Pro does something this trade depends on and Nexa doesn't.
Over three years, Housecall Pro's $79 plan comes to $2,844 ($948 a year), and the Max plan, which has recurring service plans and route optimization, is $329 a month billed monthly. Nexa is $279 once, or $458.64 over three years with the optional $4.99 monthly Cloud Sync. A solo tech who mostly invoices, runs recurring jobs and keeps the books, with no crew to dispatch, could reasonably save money with Nexa. A shop with several trucks that relies on GPS, dispatch, texting, QuickBooks sync or recurring service plans should stay with Housecall Pro. Either way, keep license, CE and certification dates in a separate credential-tracking record, because neither tool covers that.
Our read for water treatment techs: Stay with Housecall Pro if you dispatch trucks or rely on GPS, texting or recurring service plans, since Nexa lacks them. Neither tool tracks licenses or CE, so keep that record separately.

Housecall Pro costs water treatment techs $948/year at today's list price. Nexa is $279 once for invoicing, scheduling, CRM, time tracking and accounting in one suite — so after 3.5 months it has cost less than Housecall Pro, and you own it after that. What it is not: hosted-for-you software with a support desk and a roadmap you can lobby. That is the trade, and the rest of this page is the detail behind it.
Nexa is $279 once, about $23 a month over its first year. Its Drain Guard reads your expenses (from a linked bank, an imported statement, or ones you type in), finds the charges that repeat, and adds them up by the month. Keep or Cut then walks you through them one at a time. Cancel $23 a month of charges you'd forgotten about and Nexa has paid for itself inside the first year, before you count the Housecall Pro bill you'd stop paying.
It depends on what you find and what you cancel, so we don't promise a number. In our demo data, Drain Guard finds 5 subscriptions adding up to $110.13 a month. That is sample data, not a customer's.
The verdict for water treatment techs: Stay with Housecall Pro if the needs in our read above apply to you. If they don't, Nexa covers the core invoicing, scheduling and books for $279 once against $2,844 for Housecall Pro over three years.
Time tracking, invoicing, job tracking and the books are the pieces of that day. Some tools rent you each piece separately. A few — Nexa among them — bundle the lot into something you buy once. The sections below price both routes honestly.
None of that is a software problem you can buy your way out of in one click — it is why the tool you pick matters more than what it costs. Housecall Pro solves some of it. So does Nexa. The difference is what you are left holding in three years.
Today's list price is $79/month — $948 a year, from Housecall Pro's own pricing page. Every figure below is that price, multiplied. Nothing is projected.
Nexa: $279 once (or 3 × $99). Over the same three years, that is $2,565 less.
If Housecall Pro raises its price, the three-year cost goes up; if it cuts it, the cost comes down. We don't guess which. Add-ons, extra seats and card-processing fees are not included, on either side.

✓ and ✗ for Housecall Pro come from its own published feature list. — means the feature isn't in that list, which is not the same as Housecall Pro lacking it: check with them. Three years is at today's price.
Straight from Housecall Pro's own feature set. If one of these is the reason you pay them, that reason does not disappear because Nexa is cheaper.
Housecall Pro is the better call if you need online booking for home services specifically, or if your team is large enough that per-seat pricing still beats buying software outright.
Housecall Pro describes itself as 'Tailored for teams of 1 to 100+' and aimed at home service pros across 50+ industries, including HVAC, plumbing, electrical, cleaning, lawn care and pest control. (housecallpro.com)

Software doesn't do the actual work — it automates the business around it. And that part is the same for every water treatment tech: find the work, manage it, bill for it, get paid. Each step has a tool — and the right single tool runs the whole loop, so the handoffs are automatic and you get back to the actual work. Tap a step to see what gets automated.
A lead, a call, a referral — and a quote or estimate that turns it into a booked job.
The part you actually get paid for — with the time, materials, add-ons, and tasks tracked as you go, not guessed at later.
The work becomes the invoice — the hours, the add-ons, the materials, the deposit credited — totaled and sent, instead of re-typed at 9pm.
Paid by card or link, the deposit credited, and what's overdue chased — without you doing it by hand.
You can stitch four separate subscriptions across these four steps, or run one tool that does the whole flow so a booking becomes a job becomes an invoice becomes a payment without re-typing. Either way the goal is the same: less time on the business of the business, more on the actual work. (Nexa is built to be the one — but the honest options for each step are above and below.)
This is the connection that makes the rest worth it. A water treatment tech's job already holds the services, the hours, the add-ons, and the materials — so the invoice builds itself from the work instead of you re-typing it at 9pm. Toggle an add-on or nudge the hours and watch it recompute.
You didn't write this invoice — the job did.

The median water treatment tech earns $55,000/year. At $948/year, Housecall Pro is a recurring slice of that — paid again every year, whether the year was good or not. Owning the same jobs outright is $279 once, and the slice stops.
Nexa is $279 once. Invoicing, scheduling, CRM, time tracking, accounting — all connected, built for water treatment techs. You own it like you own your TDS meter, hardness test kit, and pH meter.
An honest fit check — because the wrong tool is worse than no tool.
The honest fit: if you're a solo or small water treatment techs business that owns its tools and is sick of renting software, Nexa replaces your whole stack for $279 once. If you're scaling past a handful of crews, a fleet platform may fit better — and we'd rather tell you that now than sell you the wrong thing.
Year-round construction in SoCal. Fire season (June-November) drives restoration demand. Drought impacts landscaping. Earthquake retrofitting is ongoing market.
Extreme summer heat drives HVAC demand. Hurricane risk on Gulf Coast. Year-round construction. Rapid population growth in DFW, Austin, Houston, San Antonio creates sustained demand. Freeze events (like 2021) create emergency plumbing/HVAC surge.
Hurricane season June-November creates massive restoration demand. Snowbird season November-March boosts service volume 30-40%. Year-round construction. Pool service is year-round industry. Pest control peaks in summer humidity.
Harsh winters in upstate, moderate in NYC. Construction limited in winter upstate. NYC market is enormous but hypercompetitive. Brownstone/pre-war building maintenance is specialized trade. NYC licensing is notoriously complex.

Most of my customers are homeowners on well water or with hard city water, and every job starts with a water test: hardness, iron, pH, and sometimes bacteria or nitrates sent to a lab. The results decide the system; there's no point selling a softener to someone whose real problem is iron or acidic water eating their pipes. Installs mean cutting into the main line, adding a bypass so the house still has water if the system needs service, and plumbing in the softener, filters or reverse-osmosis unit under the sink, with a drain line and a brine tank sized to the household. I program the system for the water and the family's usage. The recurring side of the business is service: salt deliveries, filter changes, UV bulb replacements, and annual checks, which keep systems working and customers coming back. Commercial clients, restaurants and offices, need their own maintenance schedules. Well water can change after heavy rain or drought, so retesting is part of the job. Quotes include the test results, so customers see why I'm recommending each piece.

The tools of the trade — each a one-time buy that earns its keep for years.
Here's the bar that matters: you spent $1,430–$6,430 on tools that last for years, and never thought twice. So why should the software cost more than your whole kit — every single year? Hold it to the same standard as a good tool: $279, once.
We build a water treatment tech's guide the same way every time, and we'd rather you trust it than take it on faith. Nexa is our product, so the test we hold ourselves to is simple: a tool only "wins" a job here when it genuinely does that job better for a water treatment tech — and where something free, open-source, or buy-once does it better, we say so and link you to it. Where Nexa falls short (payroll is the honest example), we name the alternative outright.
Found something out of date? Prices change and we don't catch every move the day it happens. This guide is published and maintained by the Nexa team; if a figure here is wrong, tell us and we'll fix it — getting it right matters more to us than the sale.
For solo water treatment techs and small teams, yes. invoicing, scheduling, CRM, time tracking, task management, and full accounting — all for $279 once. Housecall Pro may be better if you have a large team (10+) or need enterprise-specific features.
Housecall Pro has features like Online booking for home services and GPS tracking that some businesses rely on. For most solo water treatment techs, these aren't dealbreakers.
At $79/month, Nexa pays for itself in 3.5 months. After that: $948 saved every year.
Yes. Nexa is $279 as a one-time payment, or 3 payments of $99 ($297 total). Either way it's a one-time purchase — no subscription, no recurring fees ever.
