Service Business Challenges

Professional service firms — consultancies, engineering companies, architects, IT services, and similar businesses — operate fundamentally differently from product-based companies. Their primary assets are people and expertise, making time tracking and project management central to operations.

Unique Characteristics

  • Project-Based Revenue: Income tied to specific client engagements
  • People as Product: Staff time is the primary deliverable and cost
  • Variable Demand: Workload fluctuates with project wins and completions
  • Complex Billing: Multiple billing models (fixed fee, T&M, retainer, milestone)
  • Intellectual Property: Deliverables are knowledge-based, not physical
  • Client Relationships: Repeat business depends on satisfaction and trust

Common Pain Points

  • Utilization Blindness: Not knowing if staff are fully productive
  • Scope Creep: Projects expanding without corresponding fee adjustments
  • Billing Delays: Late invoicing due to time entry backlogs
  • Profitability Surprises: Projects losing money without early warning
  • Resource Conflicts: Over-committing key staff to multiple projects
  • Administrative Overhead: Too much time on admin versus billable work

What Professional Services Need

  • Integrated project and financial management
  • Seamless time and expense capture
  • Flexible billing capabilities
  • Real-time profitability visibility
  • Resource planning and forecasting


Project Setup and Planning

Effective project management starts with proper project setup and planning structure.

Project Structure

Project Types

DNA ERP supports various engagement types:

  • Fixed Fee: Agreed price for defined scope
