Integrations as a Service

Make your systems
work as one

At CatalystOne, we know that HR data doesn’t live in isolation. To create smooth employee experiences and efficient business processes, your HR system must connect seamlessly with the rest of your IT ecosystem. That’s why we offer Integrations as a Service (IaaS): a flexible, fully managed way to connect CatalystOne with the systems you already use.

Integrations you can trust

CatalystOne has a proven track record of building and running robust integrations. We draw on a growing library of reusable, well-documented integrations that we extend when needed, making projects move fast without sacrificing quality.

  • Standard pre-built and configurable integrations for common payroll, identity & access, ATS, time & attendance/workforce management, LMS, benefits systems and more - tailored to your rules and formats.
  • Custom integrations when you need something new. Designed and delivered by our technical consultants.
  • Partner integrations with selected vendors that are straightforward and fully supported end-to-end by CatalystOne.

We design integrations to be as simple as possible, without compromising flexibility. When configuration is needed, we handle it together with you.

Our consultative approach

CatalystOne offers a consultative approach throughout the whole integration project. We begin with a discovery workshop. Together with your team, we map the process you want to support and system to integrate. We document mapping rules and technical requirements, then agree clear acceptance criteria before we build. 

Next, we guide you towards the fastest and safest path, always focused on making sure the investment is worth it for your organisation. We use existing integration logic where it fits, and design and develop new solutions when needed. From there, we verify everything technically and guide you through testing and sign-off. 

Our integrations runs on our secure Microsoft Azure-based setup. Once live, we operate the integrations as a managed service: we monitor and resolve infrastructure-level issues proactively, while data-quality corrections remain with you (with sensible validations we define together). It keeps ownership clear, delivery fast, and outcomes reliable. We aim for your end-to-end process to work, not just the field-to-field map

Integrations as a Service

Make your systems work as one

CatalystOne holds the employee record, and every other system in your landscape reads from it, so a job change happens once and lands everywhere. We build and maintain every integration ourselves, we add new ones continuously, and we develop custom integrations for anything not yet on the list.

One governed employee record, hosted on Microsoft Azure.

Prefer to build yourself?

Use our APIs with a sparring partner. If you develop in-house, we provide secure API access plus advisory support on what data to expose and how to design robust flows. You’re never left on your own with just documentation.
