Hassan Ateeq · white-label builds for home service agencies
Your clients book more jobs. You keep them longer.
I build the white-label GoHighLevel, n8n and AI agent systems that answer every HVAC, roofing and home service lead in seconds, book the appointment and put the revenue on a report your client can see.

Why contractor accounts churn
Good leads die in three places. You get blamed for all of them.
Contractors don't cancel because the ads stopped working. They cancel because the leads you sent never turned into jobs they could see. That happens after the click, and it's fixable.
The slow reply
A form lead from 9 PM sits until the office opens. By then somebody else has booked the estimate.
The fixText, call and email inside the first minute, then follow-up until they book.
The invisible result
Jobs get booked, but nobody ties them back to your campaigns. At renewal the client can't see what you did for them.
The fixA dashboard that connects ad spend to booked jobs and revenue.
What I build
White-label GoHighLevel and AI automation, from ad click to booked job
Take one piece or hand over the whole delivery stack. All of it ships under your brand, with documentation your team can maintain.
GoHighLevel builds & snapshots
A complete contractor sub-account, built once and built properly, so it clones cleanly to every HVAC or roofing client you sign after.
- Pipelines that mirror lead, estimate, job and invoice
- Calendars, forms, funnels and booking pages
- Niche snapshots you can resell again and again
n8n AI automation
For everything GoHighLevel workflows can't do on their own. AI that reads the lead, decides what it is and sends it to the right place.
- AI lead qualification, scoring and routing
- Custom reporting and API integrations
- Self-hosted, so costs don't climb per task
AI voice agents
An AI receptionist for after-hours and overflow calls. It qualifies the job, books the slot and passes real emergencies to the on-call tech.
Speed-to-lead & missed-call text-back
Every form fill and missed call gets a reply inside a minute, then a multi-day SMS, call and email sequence that runs until they book.
Review & reputation automation
A Google review request goes out the moment a job is marked complete. Unhappy customers get routed to the owner privately first.
Reactivation & seasonal campaigns
Tune-up season, storm weeks, unsold estimates. Campaigns that pull booked jobs out of the customer list your client already paid for.
Client reporting dashboards
Ad spend, leads, booked jobs and revenue on one screen. The report that makes your retainer an easy yes at renewal.
Ongoing white-label fulfillment
Or hand me the whole queue. Your brand stays at the front and I stay invisible, working in your Slack to your deadlines.

Why it's low risk
You've been burned by a contractor before. Here's what's different.
Every part of how I work is set up to take the usual risk off your side of the table, in writing, before any work starts.
Fixed price, quoted in writing
Your cost is agreed before I start and doesn't move mid-build, so your margin is locked the day you quote the client.
You own everything, from day one
I build inside your account. Every snapshot, workflow and n8n flow is yours whether we work together again or not.
NDA and non-solicit before access
Signed before I touch anything. I work with agencies only and never approach your clients. That's a contract term, not a promise.
30 days of free fixes
If something isn't working the way it was scoped, I fix it. No change-request invoice for my own loose ends.
Documented, so you're never dependent
Every build ships with SOPs and a Loom walkthrough. Your team can maintain it without me on retainer.
No retainer lock-in
Start with one build. If it goes well, do another. There's no minimum term and nothing to cancel.
How it works
How a white-label build works: sold to shipped in four steps
You brief me once. I scope it in writing, build it, and hand it over as yours.
-
We map the account
A 30-minute call. What the contractor needs, what already exists, and where leads are leaking right now.
-
You get a fixed quote
A written scope, a flat price and a delivery date within 24 hours. Mark it up, quote your client, approve when ready.
-
I build and test it
Built in your account so you own it from day one, then tested end to end. Every trigger fired, every message read.
-
Handoff and support
A Loom walkthrough, written SOPs, and 30 days of free fixes for anything that isn't working as scoped.
Usually replies in a few hours
Who you're working with
No account managers. No juniors. You work with me.
I'm Hassan Ateeq. I started Hasnex Systems after watching agency owners close good retainers and then lose the margin, and the weekend, to fulfillment nobody had capacity for.
Every project runs through me. I scope your build, I'm in the Slack channel, and I'm the one accountable when a workflow misfires at 11 PM. You'll never be handed to someone you didn't meet, or chase a person who has to “check with the team.”

FAQ
What agency owners ask before the first build
What does Hasnex Systems do?
Hasnex Systems is a white-label build partner for marketing agencies whose clients are HVAC, roofing and other home service contractors. I build the GoHighLevel systems, n8n automations and AI voice and chat agents those agencies sell, and deliver them under the agency's own brand.
What is white-label GoHighLevel fulfillment?
Your agency sells the GoHighLevel setup, automation or AI agent to your client, and I build it behind the scenes inside your account. Your client only ever sees your brand. You set the price for your client, and I charge you a fixed fee agreed in writing.
Will my clients ever know you exist?
Only if you want them to. Everything ships under your brand, and I'll work from an email address on your domain. If you'd rather I join client calls as your build team, I do that too.
Why n8n and not just GoHighLevel workflows?
GoHighLevel workflows handle most follow-up well, and I use them wherever they fit. n8n takes over where they run out: multi-step AI logic, pulling ad spend into a report, or anything that needs a real API call. It can also be self-hosted, so your costs don't climb with every task as client volume grows.
Do you build in my account or yours?
Yours, normally, so you own every asset from day one. If you'd prefer, I can build in a staging sub-account and transfer the snapshot across once you've approved it.
How long does a build take?
A single funnel or snapshot is usually 5 to 10 business days. A full contractor system with AI agents averages around two weeks. You get the exact date in writing before you commit.
What does a build cost?
It depends on scope, so I don't publish a price list that would be wrong for your project. What I commit to is a flat figure in writing within 24 hours of our call, not an hourly rate that drifts. That gives you a fixed cost to mark up before you quote your client.
Will you go after my clients?
No, and it's contractual. I sign an NDA and a non-solicit before I get any access. I work with agencies only. Your client relationships are the entire reason this model works.
What happens on the first call?
Thirty minutes, no deck. You describe one contractor account you're struggling to deliver for, I tell you how I'd build the system and what it costs. You leave with a scope and a price whether you hire me or not.
Let's talk
Bring me the contractor account you're worried about.
Thirty minutes. Tell me about one client whose leads aren't turning into jobs, and I'll map how the system gets built, what it costs and when it ships. That's yours to keep whether you hire me or not.
- No deck, no pressure, no follow-up sequence
- Written scope and fixed quote within 24 hours
- NDA signed before anything is shared
