Coretime's baseline feature set includes Time Recording, Expense Management, Invoicing and Reporting but it can do much more.

By adding in the additional functionality described below Coretime can grow to be an integrated, easy-to-use and cost-effective system optimised for Professional Services businesses. 

You can add these functions in any order and at a time to suit you; so you only ever pay for for capabilities you need... 

Coretime CRM

Working hand in hand with your Coretime Project Management system, Coretime CRM is an exciting new module that allows you to see all communications and interactions with your Clients in the same place.

Coretime CRM allows you to drill-down to view communications at the Contact, Project or Client level, ensuring a 360-degree view of your interactions at any one time. 

Fully GDPR compliant with a comprehensive search function to interrogate the database it's impossible to not always have full project visibility.

Mobile App for Coretime

The Coretime Mobile App provides real time, on-the-go time and expense management that you can use in conjunction with the way you normally use your Coretime system. Our App provides a fresh, clean user experience that makes the task of time and expense entry even easier.  


  • Enter Time and Expenses against multiple Projects, Phases and Activities – picking up your existing Coretime configuration
  • Dictate notes against Time and Expense entries – saving time
  • Capture Receipts against Expenses using your device’s camera – these are then stored in your main Coretime system
  • All existing Coretime controls are replicated (e.g. budgets and access restrictions)​
  • Data synchronises both ways with your existing Coretime system – Time and Expense information entered on the App shows in the web browser and vice versa
  • Works with both Coretime.com (SaaS/Cloud) and On Premise Coretime deployments
  • Admin console so you can choose which users have access and on which devices
  • Secure Connection
  • Compatible with Android and iOS devices


  • Coretime already installed 
  • Google Play or App Store Account
  • Android or iOS device (phone or tablet) with Internet access
  • You will need to provide your company’s SSL Certificate

Resource Manager

The new Resource Manager module adds an extra dimension to capacity planning in the ever expanding Coretime system.
Whereas Coretime’s existing Staff Planner module allows you to effectively schedule resource, it can demand too much detail and certainty for some businesses. The Resource Manager operates more on a ‘rough cut’ basis allowing key users to estimate how much resource they will need per week or per month rather than per day.

Purchase Order Module

Purchase Order Module

Staff Planner

An effective resource planning tool with a simple wall planner interface which allows Managers to ensure they have the right staff available at the right time on their projects.
