The closed CRM problem

A CRM that locks your data inside a closed system and controls which tools you can integrate with is a ceiling on your agency's technology stack.

agentOS is built on an open API -- which means it connects to the PropTech tools you choose, not just the ones your CRM vendor has decided to build integrations with.

"We want to adopt a new PropTech tool but our CRM says integration is on the roadmap and will take 18 months."

A closed CRM is a technology ceiling. agentOS's open API means you can connect to new tools when you choose them -- not when your vendor gets around to building the connection.

"Our CRM keeps promising an integration with X tool that never seems to arrive."

Vendor roadmaps rarely align with your agency's priorities. With agentOS's open API, you do not wait for the vendor to build each integration -- you connect to the tools you need when you need them.

"Our sales and lettings teams are in separate systems and data gets out of sync."

agentOS covers estate agency sales, lettings management, client accounting and property management in one platform. Sales and lettings staff share a database without a separate sync or manual export.

"Support is hard to reach when something goes wrong and we need an immediate answer."

agentOS offers phone, live chat and an online helpdesk with video guides and articles. Direct access to a human when you need it is part of the platform's proposition.

How agentOS works for your agency

Six capabilities in one open platform that connects to the PropTech stack you choose.

agentOS covers the full agency workflow -- and because the API is open, it connects to referencing providers, compliance tools, portal feeds and any other PropTech you adopt.

1

Estate agency CRM

Manage your full sales pipeline from valuation to completion. Instructions, viewings, offers and progression tracked in one database with portal feeds and client communication integrated.

2

Lettings management

Full lettings lifecycle from tenancy creation through rent collection, maintenance tracking and compliance. Designed to run alongside the sales module from the same database.

3

Client accounting

Landlord statements, client account management and invoice handling within the CRM. Standard lettings and management accounting without a separate package.

4

Property management

Track maintenance requests, contractor management and property compliance from within agentOS. Connected to the tenancy record so property managers see the full history in one view.

5

Open API for PropTech connectivity

agentOS's open API allows connection to a wide range of PropTech tools. Referencing providers, portal feeds, compliance tools and more can be integrated without waiting for the CRM vendor to build a native connection first.

6

Live support and helpdesk

Phone, live chat and an online helpdesk with articles and video guides. Support from a team that understands the platform and the UK agency workflows it is built for.

We moved to agentOS because we were tired of being told that an integration we needed was 'on the roadmap'. The open API means we have connected the tools we actually use without waiting for anyone's permission. The support team has been responsive every time we have had a question. It is a solid, reliable CRM for an agency our size.

Frequently asked questions

What agents ask about agentOS.

What does 'open API' mean for my agency?
An open API means agentOS publishes documented interfaces that allow other software to connect to it directly. In practice, this means PropTech suppliers can build connections to agentOS without waiting for agentOS to build each integration. Your agency can connect tools you choose, not just those on an approved list.
Does agentOS cover both sales and lettings?
Yes. agentOS covers estate agency sales, lettings management, client accounting and property management in one platform. Sales and lettings staff access the same database and property records are shared across both sides of the business.
Is client accounting included or a separate module?
Client accounting is included within agentOS. Landlord statements, client account management and invoice handling are built into the platform. For more complex requirements, agentOS can connect to external accounting tools via the open API.
What support is available?
agentOS offers phone support, live chat and an online helpdesk with video guides and articles. Support is accessible directly -- not through a ticket-only system.
Is there a minimum contract term?
Discuss contract terms directly with the agentOS team via the Kerfuffle route. Your Kerfuffle account manager can be part of that conversation.
How does migration from my current CRM work?
agentOS's team supports the migration of your existing data. Property records, landlord and tenant information and historical records are migrated across. The team works through the import process with you to ensure the data lands correctly.
