Time tracking, project control, and billing software for specialist teams

Don’t see your sector listed? Coretime helps project-based and professional services teams capture time, manage costs, stay on top of delivery, and invoice with confidence.

Where specialist teams lose time, visibility, and revenue

If your team runs projects, tracks internal or client-facing work, and needs to turn time and costs into accurate billing, disconnected systems quickly create admin, missed revenue, and poor visibility.

Billable time gets missed

Capture hours against clients, properties, jobs, or tasks, whether the work happens on site, on the road, or in the office.

Expenses and mileage are hard to keep on top of

Record costs as they happen and link them directly to the right project or client, without chasing paper trails later.

Project performance is difficult to see clearly

Stay closer to budgets, time spent, and profitability with live visibility across active work.

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!

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.

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.

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.
