SAP for professional services connects them in one flow. Consulting, engineering, IT services and other professional firms live and die by utilisation and project margins. When project plans, time sheets and billing sit in separate tools, margin leaks without anyone noticing.

In 30 seconds
  • SAP connects projects, resources, time and billing.
  • Billing comes straight from approved time and expenses.
  • Utilisation and margin are visible per project.
  • Faster billing means faster cash.

Key benefits of SAP for professional services

  • Clear view: project, client and team performance in one place.

Common mistakes to avoid with SAP for professional services

Time captured twice

Capture time once and use it for billing and costing.

Staffing by spreadsheet

Use skills and availability data to staff projects.

Billing at month-end only

Bill as milestones are reached to protect cash flow.

Margin reviews too late

Track project margin weekly, not after completion.

A worked example: an engineering consultancy

Illustrative example

This scenario is a composite of common situations, not a specific client.

An engineering consultancy bills clients a month late because time sheets are collected by email.

With SAP for professional services, consultants enter time on mobile, managers approve it weekly, and invoices are generated from approved time.

Billing happens weeks earlier, utilisation is visible by team, and margin issues are spotted while projects can still be corrected.
