Why Choose Coretime Migration?
Coretime's migration process emphasises speed, security, and reliability for professional services firms. Expanded details below highlight our streamlined approach based on proven practices.
Fast Go-Live Timelines
Achieve full go-live in just 1-2 days with minimal downtime, allowing your team to start tracking timesheet's and projects almost immediately. This rapid implementation follows a structured assessment, data transfer, and testing phase to ensure everything is production-ready without halting operations.
Secure, Duplicate-Free Process
Our secure migration includes a thorough assessment phase where we review your current setup, identify potential issues, and plan data transfers to eliminate duplicates entirely. Data is encrypted during upload, with validation in test instances before live deployment, minimising risks and ensuring compliance for UK and Irish firms.
Continuous UK Support
Post-migration, receive ongoing support from UK-based experts available via email or phone (9am-5pm, weekdays), including quarterly check-ins for optimisations. Your dedicated account manager handles any tweaks, training, or expansions, ensuring long-term smooth performance and ROI growth.
Seamless Account Integration
Enhance your migration with direct accounts integration, syncing timesheets, expenses, and projects with Sage, Xero, QuickBooks, or Microsoft Dynamics for automated invoicing and real-time financials. This eliminates double-entry, accelerates cashflow, and ensures accurate profitability reporting from day one.
GWP’s rollout of Coretime followed a typical implementation path.
Coretime helped GWP migrate historical timesheet data, align project and billing structures, and get staff up and running quickly with training and permissions in place. Within weeks, the team had moved away from manual forms, with better visibility of hours, budgets and profitability.

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.

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.
