Why Our Customers Choose Coretime for Smarter Time Management and WIP Tracking

What is Coretime?

Coretime is a cloud-based project management and time tracking system used by professional services organisations to simplify the capture, monitoring, and reporting of time, expenses, projects, and invoicing.

Instead of juggling spreadsheets or disconnected systems, businesses can centralise essential tools timesheets, project planning, leave management, invoicing, and CRM within a single integrated platform.

Why Time Tracking Matters

Accurate time tracking software is the foundation of billing accuracy, project performance, and profitability. Without it, businesses risk:

  • Lost billable hours
  • Delayed invoices
  • Inaccurate project costs
  • Poor visibility and profitability

Coretime’s timesheet and expense tracking features allow teams to log hours in real time via desktop or mobile, reduce manual errors, and ensure financial reporting reflects actual project delivery.

What is Work in Progress (WIP)?

Work in Progress (WIP) refers to all work started but not yet completed or billed. For professional services, WIP represents a significant part of your revenue pipeline the ongoing effort that eventually becomes invoices and income.

Without accurate WIP tracking, businesses may face:

  • Underbilling or revenue leakage
  • Poor cashflow forecasting
  • Projects that seem profitable on paper but aren’t in reality

How Coretime Helps Manage WIP

Coretime turns timesheet entries into actionable business insights. Through its invoicing and reporting capabilities, you can:

  • Generate invoices directly from tracked hours and expenses
  • Review WIP balances to see pending work
  • Forecast future income and resource utilisation
  • Ensure financial clarity for project leaders and finance teams

Coretime also integrates seamlessly with Sage and Xero, reducing data re-entry and improving accuracy.

Resource Planning and Leave Management
