Where your week goes

Sales

Leads wait for a reply

Website forms, ad leads, missed calls and cold email replies.

Someone enquires at 9:41 PM. You reply the next morning. By then, they've booked with whoever answered first.

New enquiry from your website“Do you have availability this month?”
You reply at 10:30 AM the next day
Operations

Your team does the same admin every week

Client reports, QA checklists, onboarding and handoffs.

Every Monday someone copies numbers into a report by hand. It takes half a day, and it's work a system should be doing.

Monthly client reports12 clients · built by hand in Sheets
Half a day, every week

Growth Orbit systems handle both, so your team spends its time on work only people can do.

Set up once. Then it runs on every lead.

A lead comes in

From your website, your ads, a missed call or a reply to your cold email. It doesn't matter what time it is.

Hi James, it's Harbour Lettings. Thanks for getting in touch. Yes, we cover Leith. Are both flats 2-bed, and are they empty now?
Both 2-bed. One's empty, the other's free from next month.
Perfect. Sarah looks after Leith. Would one of these suit for a quick call?

Booked, logged and handed over

The call goes into your calendar, the CRM updates itself, and the right person gets a summary before the call. No one copies anything between tools.

The admin runs itself

Reports, follow-ups, onboarding and handoffs run on a schedule. You get the numbers every Monday without anyone building them.

Works with the tools you already use

No rip-and-replace. I connect the software you already pay for, then add AI where it actually saves time. Your business stays in the middle, and everything else orbits around it.

Who you'll work with

An accountant who builds AI systems

I started in finance, where I cut a 250-person payroll run from two weeks to one to three days. Then I spent years writing sales emails, ads and scripts for 290+ clients. Growth Orbit puts both together: systems that are checked to the penny and talk to your customers like a person would.

More about me

Questions

Do I need a CRM already?

No. If you use one (GoHighLevel, HubSpot, Pipedrive, ClickUp), I build on it. If you don't, I'll set up the simplest option for your size as part of the build.

Will the AI sound like a robot?

No. Replies are written in your words, by someone who has written sales copy for 290+ clients. The AI fills in the details from the enquiry, and anything unusual goes to a person.

What if it says something wrong to a customer?

It works inside clear rules: approved answers only, a hand-off to a human when unsure, and a log of every conversation. Nothing goes live until you've tested it.

How long does it take?

Most systems are live in 14 to 30 days. You get a written plan within a few days of our call, with the timeline in it.

What does it cost?

Every project gets a fixed price in the written plan, before any work starts. No hourly billing and no surprises.

Who owns the system?

You do. Everything is built in your own accounts, with written docs and Loom walkthroughs so your team can run it or change it without me.

What do I need to give you?

Access to the tools you already use, an hour of your time to explain how you sell and work, and someone to test the system with me before launch.
