- Work in Progress – Shows the current state of a project in terms of work that’s started but not yet completed or invoiced. Useful for seeing which projects have active work ongoing.
- Total Hours Worked – The cumulative number of hours logged on that project (or client) so far. Helps you understand effort invested, and compare against budgeted time.
- Fee Left to Complete – The monetary value of remaining work on the project before it’s fully billed i.e. how much budget or contract fee remains to be earned.
- Invoiced to Date – The total amount you’ve already billed the client for that project. Useful to see how much of the agreed contract value has been converted into invoices.
- Last Time Entry – The most recent time log added to the project. This helps managers or stakeholders see how up-to-date the project’s time tracking is, and when someone last recorded effort.

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.

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.

Callisto Consulting
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.

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.

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.
