Automated Project Billing with PSA Software

Automated project billing is a critical capability for modern professional services firms, particularly those operating in architecture, engineering, and consulting. When project data, time recording, and billing systems are disconnected, firms face delayed invoices, missed billable hours, and limited visibility into project performance.

Coretime’s approach focuses on integrating project management and time tracking, billing, and financial workflows into a single time and billing system designed for professional services teams. This ensures billing is driven directly from accurate, approved project data not manual rework.

The Challenges of Manual Billing Processes

Many firms still rely on spreadsheets or disconnected tools for employee timesheet software, expense tracking, and invoicing. This manual approach increases the risk of errors, missed billable hours, and inconsistent job costing.

Without integrated project management software for Architects and engineers, billing becomes time-consuming and reactive. Automated billing ensures approved time and expenses flow directly into invoicing, reducing administration and improving billing accuracy.

Accurate Time Recording Drives Reliable Billing

Accurate billing starts with accurate time capture. Coretime supports billable hour tracking through structured project management and time tracking tools that allow employees to record time against jobs and phases as work is completed.

This approach supports architecture and engineering workflows while providing reliable data for job costing software and invoicing ensuring all billable work is captured before invoices are created.

Automated Timesheets and Built-In Alerts

Late or incomplete timesheets are a common cause of delayed billing. Coretime includes automated reminders and built-in alerts that prompt employees to submit timesheets and managers to approve them on time.

These alerts help maintain data accuracy and ensure time and expense information is always ready for billing. By reducing delays at the source, firms can invoice more consistently and improve cash flow without increasing administrative effort.

Integrated Expense Management

Expenses are captured alongside time using built-in expense management software, ensuring reimbursable and billable costs are not overlooked. Approved expenses automatically feed into the billing process, improving accuracy and reducing the need for manual reconciliation.

This integration supports better financial control while maintaining a clear audit trail for both internal teams and clients.

From Project Data to Invoices — Without Duplication

Once time and expenses are approved, Coretime automatically makes that information available for billing. This removes the need to re-enter data into separate invoicing tools or spreadsheets.

As a small business invoicing software and professional services platform, Coretime supports flexible billing models, including hourly, fixed-fee, staged, and retainer billing all driven directly from project data.

Real-Time Job Costing and Project Visibility

Automated billing provides continuous insight into project performance. As time and expenses are recorded, Coretime updates:

  • Job costing and budgets
  • Work in progress (WIP)
  • Billable versus non-billable time

This real-time visibility is essential for architecture and engineering firms relying on job costing software to monitor profitability and make informed decisions before invoicing occurs.

Accounting and Client Billing Integration

Coretime integrates directly with accounting systems, such as Xero & Sage ensuring invoices and financial data flow seamlessly between platforms. This client billing integration eliminates duplicate data entry and supports consistent financial reporting.

By connecting project billing with accounting, firms maintain a single source of truth across project management, billing, and finance reducing errors and simplifying month-end processes.

Supporting Workforce and Resource Management

Because time, projects, and billing are connected, Coretime also supports effective workforce management software capabilities. Firms can see how staff time is allocated across jobs, improving resource planning and utilisation while maintaining accurate billing data.

Designed for Professional Services Firms

Coretime’s approach reflects how professional services firms actually work combining:

  • Software for architecture practices
  • Project management software for Architects
  • Project management and time tracking
  • Employee timesheet software
  • Billable hour tracking
  • Integrated invoicing and accounting integration

By automating the flow from timesheets and expenses through to invoices and accounting, firms can reduce administration, improve billing accuracy, and gain greater control over project profitability.
