The Biggest Threat to Your Profits is Contract Value Leakage!

  • Contracting parties need to secure economic value during the lifetime of their contracts.
  • Many companies, however, see at the end of each year lower revenues and/or higher costs than expected or forecasted.
  • This is caused by ‘contract value leakage,’ often due to low contract quality: poor contract management, and high contracting costs.

“Contract value leakage can lead to an average of more than 10% loss of revenue and cost millions, especially in industries producing high-value and complex products and services.”
