Professional Services ERP Requirements Overview
Professional services firms — consulting, IT services, engineering, accounting, and legal — have fundamentally different ERP needs than product-based businesses. Your primary asset is people, and your ERP must excel at project accounting, resource management, time tracking, and flexible billing models.

Frequently Asked Questions
What's the difference between ERP and PSA for professional services?
Professional Services Automation (PSA) tools like Maconomy, Kantata, or FinancialForce focus exclusively on project delivery and resource management. An ERP provides broader capabilities including finance, HR, and procurement. Many firms start with PSA and add ERP as they grow, or choose an ERP with strong project capabilities.
Do professional services firms need inventory management?
Typically no. Professional services firms should deprioritise or skip Inventory, Manufacturing, and Supply Chain modules. Focus your evaluation on Projects, Finance, HR, and Analytics.
