The problem this solves

Why estate and letting agents look at Greenhouse OS.

Fully customisable CRM and operating system for estate agents - built by agents, for agents, designed to replace spreadsheets and rigid software. Here is what drives agents to look for a better solution.

"Our CRM doesn't work the way we work - we manage the gaps with spreadsheets."

Greenhouse OS eliminates the spreadsheet problem by letting you build the system around your processes, not adapt your processes around the system.

"We have years of client data that we are not using."

Greenhouse OS's data activation process turns that dormant data into live valuation opportunities from the day you go live.

"Our fee structure is fixed because our CRM can't support anything else."

Greenhouse OS is built to support flexible fee models alongside traditional pricing. Agents who have made this shift report revenue growth of over 20%.

"We want to automate our prospecting but our current CRM won't do it the way we need."

If your current CRM imposes its automation logic on you, Greenhouse OS inverts that relationship. You design the automation, the system executes it.

How Greenhouse OS works

Six things Greenhouse OS does for your agency.

Here is what you are getting access to.

1

Customisable CRM

Build your own dashboards, customer journeys and data views. You are fully in charge of what your CRM tracks, shows and automates - not your supplier.

2

Automated Workflows

Automate prospecting, viewing and valuation booking, listing creation, sales progression tracking and communications. Remove manual steps from every process.

3

Data Activation

Turn your historic client and property data into a live valuation pipeline. Identify owners in your area who are likely to sell and act on it from day one.

4

Flexible Fee Management

Support non-traditional fee structures alongside standard percentage fees. Agents using flexible fees through Greenhouse OS report 20%+ revenue increases.

5

Management Information

Custom reporting and management dashboards that track the KPIs that matter to your business - not the metrics your CRM vendor chose to surface.

Frequently asked questions

What agents ask about Greenhouse OS.

What makes Greenhouse OS different from standard estate agency CRMs?
Most estate agency CRMs give you a fixed structure with limited customisation. Greenhouse OS lets you design your own operating system - your dashboards, your customer journeys, your marketing strategies, your reporting. You are in charge of the CRM, not your supplier.
Do we need technical skills to customise it?
No. The Greenhouse OS team handles setup and works with you to build the system to your requirements. On-site hands-on training is included at go-live and UK support is ongoing.
What is data activation and how does it help us?
When you switch to Greenhouse OS, the team works with your historic data to turn it into actionable property ownership intelligence - identifying contacts who own properties in your area that could generate valuation appointments. You start generating new business from data you already hold.
What are flexible fees and why do they matter?
Greenhouse OS is built to support flexible fee models - where sellers choose how to pay rather than being given a fixed percentage. Agents who have introduced flexible fees through Greenhouse OS report revenue increases of over 20% per branch.
Can Greenhouse OS replace our current CRM completely?
Yes. Greenhouse OS covers the full range of estate agency operations: prospecting, appointments, valuations, listings, sales progression, lettings and reporting. It is designed to replace your current CRM, not sit alongside it.
How do we access this through Kerfuffle?

About Greenhouse OS

Who they are and what they do.

Greenhouse OS was founded by estate agents who were frustrated by CRMs that didn't fit how agencies actually worked. The team - led by Alex Rhodes as Managing Director and Ian Preston as Commercial Director - built the platform in collaboration with agents and continues to develop it based on agent input rather than software vendor roadmaps.
