Our mission is simple: make it effortless to capture time, understand profitability, and get invoices out accurately and on time.

Our Mission

We believe professional service firms run on time. Our mission is to give every firm a clear, real‑time view of where time goes, how projects perform, and which work is truly profitable without adding that extra admin.

How Coretime started

  1. Inside Sage
    Coretime began its journey within Sage, a trusted name in business software, where it was created to help organisations manage time and projects more effectively.
  2. Becoming independent
    Coretime became a standalone company, marking the start of its transformation into a leader in time tracking software and project management solutions for professional organisations.
  3. Focused on specialist sectors
    We grew into a dynamic, independent business with a focused mission: to simplify time, project, and expense management for consultancies, construction firms, charities, and public sector organisations, offering some of the most reliable consultant timesheet software in Ireland while staying true to the strong foundation we were built on.
  4. Continuously improving for our customers
    We’ve invested in product innovation, customer support, and sector‑specific features that help users track time and expenses, manage WIP, stay compliant, and make informed decisions to improve project profitability, powered by a close‑knit team with deep industry knowledge and a genuine drive to help businesses run more efficiently every day.

Built for professional services

We work with firms who sell expertise, not products.

  • Accountants – Streamline timesheets, WIP, and billing so every billable hour is captured and recoverability is clear.
  • Architects & Engineers – Track time by project stage, manage budgets, and protect margins on complex design and engineering work.
  • Consultancies – From environmental and IT to management, marketing and agricultural consulting, keep client work, retainers and internal projects on time and on budget.
  • Non‑profits – Track funded projects and grant time accurately, stay audit‑ready, and prove the impact of every hour spent.
  • Entrepreneurs & Freelancers – Easily log time, manage small projects, and send accurate invoices without adding extra admin.
  • Surveyors – Record site and office time by project, control WIP, and ensure your fees reflect the real work involved.
  • Archaeologists – Capture fieldwork and research hours, manage project budgets, and report clearly to clients and funding bodies.
  • We support even more industries – Coretime is also used by a wide range of specialist and project‑based organisations, from creative agencies and training providers to legal, surveying and technical services. If your work is driven by people’s time and expertise, Coretime can help you track it, manage it, and turn it into reliable revenue.

That focus means we understand your workflows, terminology, and reporting needs – from RIBA stages to utilisation targets and write‑offs.

Coretime is simply the easiest, yet the most economically advantageous programme that does so much more than just time management. The overall impact of Coretime has improved both productivity and efficiency.

JNP Group

Coretime is one of the most important packages within the business and is based on an annual subscription with full cloud access. This is a truly fantastic system and very affordable for a company of our size, it’s a fraction of the cost of some systems such as Autodesk and Microsoft.

For us, the main benefit is that our system is now more user-friendly in terms of project managers being able to access information, such as seeing how a project is performing against budget. They can analyse how time is being spent and what proportion of it is earning fees – it’s easy to translate.

It’s cut the time spent on routine administrative tasks and enabled us to be more efficient, which means we can focus more on the actual projects. We can have around 20 live projects on the go at any one time and if a client wants a breakdown of where the time is going, we need to respond almost instantly.

Aircraft Leasing & Management

We have recently purchased Coretime through Onesys and were impressed with their responsiveness to our original enquiry and to our subsequent questions. The process for understanding what the software could do for us was efficient and straightforward, as was the administration involved in setting-up the account and finalising the agreement.

Since purchasing Coretime our time spent on administrative tasks, especially around invoicing has greatly reduced. We can also now respond to Client queries much more efficiently and with a more accurate, trusted response.

Overall the processes that we undertake using Coretime are much quicker and simpler and along with the benefits we’re now receiving in how we can report on our Project data using different parameters, we expect to see a return on investment within a year based on administration time saved.

A huge positive for us is the reduction of double entry of information, not having to manipulate information and enter it somewhere else has made such a drastic difference to how we run our business, we can’t imagine not having Coretime now!
