Track time by phase, stay on top of WIP, and protect project profitability Timesheets for Architects

Coretime helps architecture firms track time across projects and RIBA stages, manage resources, improve fee visibility, and turn accurate data into faster billing.

Where architecture firms lose time, visibility, and margin

When time is hard to track by phase, project data lives in too many places, and billing depends on manual work, it becomes harder to protect margins and plan ahead.

Time is not tracked where it matters

Capture hours against projects, phases, and tasks, so you can see where fee is being earned and where it is being lost.

Project performance is hard to see early

Stay closer to budgets, WIP, and actual time spent, before issues become write-offs or awkward client conversations.

Planning and billing take too much admin

Bring time, resourcing, financial visibility, and invoicing into one connected workflow.

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.

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.
