What we do

Stop trying to fit your business into
someone else's software.

Most growing businesses end up running on a patchwork: one tool for customers, one for invoices, one for scheduling, one for email, one spreadsheet nobody trusts, and reports someone rebuilds by hand every week.

We build software made just for your business. We keep the tools you already love — QuickBooks, your email, your calendar — and make them work together. We only build what doesn't fit.

What you end up with is one system that finally feels like yours.

Why Hausstack

Built for you. Not the other way around.

Made just for you

No template. No generic platform. Your software is built around how your business actually works — not someone else's idea of it.

We keep what's already working

Using QuickBooks? Keep it. Love your email tool? Keep it. We make everything work together so the numbers flow automatically. We only rebuild what doesn't fit.

The dream system, finally built

You've been describing a better version of your software in your head for years. You say it. We build it. That's the whole job.

Your customers will notice

When your customers log in, they see something that actually looks like your business. Not a generic screen with someone else's brand. They'll treat your business differently because of it.

Your software gets better every month

When new AI models drop or we find a way to make something faster, your system gets the upgrade. Every other month, free. Your platform stays ahead while you stay focused on the business.

You don't handle any tech

We do the hard part. You don't need to learn anything new. You just run your business while we make the software fit it.

What we build

Four example systems.
Tailored to your industry.

An LA electrical contractor, a private K-12 school, a roofing company, and an HVAC shop. Each fully custom — here's what we can build for you.

Illustrative example builds. Real customer builds replace these as they go live.

Live dispatch command center

Every job today on one board, tagged by where the lead came from — Yelp, Google LSA, door hangers, referrals. Revenue ticks up live as techs close jobs.

2

AI panel inspection

The tech photographs the panel. AI reads it on the spot — flags code issues, reads the panel age, and writes the upgrade quote before they leave the driveway.

3

Marketing ROI by source

Every dollar of ad spend traced to booked revenue. Google LSA returned 5.2x. A $300 door-hanger run booked $14K. No spreadsheet, no guessing.

Morning brief
Quiet, healthy day ahead. Attendance is up 2.1%, March tuition is 92% collected, and you have 2 admissions interviews at 1:00 and 2:30. One thing worth a look: 3 families are 5+ days late on tuition.

Satellite roof measurement

Type the address. AI returns square footage, pitch, and facets from satellite in 30 seconds — the bid is drafted before anyone climbs a ladder. No drone, no Part 107 license, no per-report fee.

2

AI insurance supplement

Phone photos in. First-draft supplement out — flagged damage, line items, cause attribution. Exports straight to Xactimate ESX for the carrier in minutes, not the usual 4 hours.

3

Pipeline by lead source

Every lead — storm canvass, Yelp, Google LSA, referral — tagged automatically. Watch the Mar Vista storm canvass turn into booked installs, with revenue traced to the dollar.

Maintenance plans that renew themselves

Every service agreement, every system age, every renewal date in one place. When a plan comes due, AI drafts the renewal email in your shop’s voice — recurring revenue you don’t have to chase.

Today’s board, fully dispatched

Every call today on one board — tune-ups, no-cools, installs — tagged by status and tech. Drag to reassign. The urgent 87° house floats to the top so nobody waits.

EPA Section 608 log on autopilot

Refrigerant added or recovered on every job, logged against the tech’s 608 cert. Audit-ready the moment the EPA asks — no clipboard, no shoebox of receipts.

How it works

Most builds launch in 3–6 weeks.

From first call to live system. We handle the hard part, keep scope clear, and launch in phases so your business keeps running.

1

We listen

You tell us how your business really works. The good, the messy, the things that frustrate you. What you wish your software did but doesn't. We take notes.

Week 1
2

We plan

We show you exactly what we're going to build. On paper, in plain English. You tell us what to change. We adjust until it's right.

Week 2
3

We build

You get a working version in your hands. You try it with real data. You tell us what's not quite right. We fix it.

Week 3
4

You go live

We move your data in. We train your team. We stay close for months after to make sure it all runs smoothly.

Week 4
Get your free audit →

30 minutes. No pitch. You leave with a plan either way.

Optional add-on

Need demand too?
Add marketing after the system is in place.

Once your operations can handle the work, we can help drive more of it: social, email, SEO, websites, ads, and campaign reporting that connect back to your platform.

Social Media

A steady stream of posts across the platforms your customers actually use. Drafted for you, approved by you.

Email Marketing

Campaigns and automated sequences that keep you in front of past customers and warm leads.

SEO & Content

Content and local search work so the right customers find you on Google before they find a competitor.

Website Build

A custom-designed site built to convert. Fast, mobile, and fully yours.

Website Management

Hosting, updates, and performance handled — so your site never becomes the thing nobody maintains.

Ad Campaigns

Google and Facebook ads with the results tied straight back to your system, so you see what each source actually books.

Common questions

Everything you're probably wondering.

What if this goes over budget?

It won't. Fixed price, fixed timeline. If we're wrong, we eat the cost — not you.

What if you disappear?

The software is yours from day one. If we ever closed, you'd still have everything — the code, the data, full documentation. Standard tools any developer can pick up.

I don't really know what I want. How do I even write a list?

You don't need to. That's literally our job. The first week is us sitting with you and pulling what's already in your head into a document you'll actually recognize. Then you tell us what's wrong.

We're too small for custom software.

Between 10 and 100 people is the worst zone to be in — too complex for off-the-shelf tools, too small to hire a full tech team. That's who we built this for.

How can you do this so fast?

We use AI to handle the parts that used to take humans weeks. That's why custom software used to take 6 months and $150,000. We've moved the whole math to somewhere saner.

What happens to my existing data?

We move it in. Customer records, invoices, history — everything comes with you.

Free · 30 minutes · No pitch

Get your free audit.

We walk through your current software with you. We show you what you're paying for, where things overlap, and what one custom system could actually do for your business. You leave with a plan either way.

We'll be in touch within 24 hours to schedule. No one will call you unless you ask.
