Open Book Cost Management

Transparency - Trust - Smarter Cost Control

Open Book Cost Management is a collaborative approach to managing costs in long-term supplier relationships. By openly sharing financial and cost data, both customer and supplier work together to achieve greater efficiency, fairness, and value.

At Perpetual, we support organisations in implementing open book models that foster transparency and mutual benefit.

How It Works

Suppliers provide detailed breakdowns of all costs, including materials, labour, overheads, and other project-related expenses. This data is then reviewed jointly with the customer to ensure fair pricing and identify areas for cost optimisation.

Benefits of Open Book Cost Management

Greater transparency across the supply chain

Stronger partnerships built on shared goals and open communication

Cost-saving opportunities through collaborative analysis

Improved efficiency, as suppliers are incentivised to streamline processes

Fair, data-driven pricing that benefits both parties

What It Takes to Work

Open Book Cost Management relies on a foundation of trust, open communication, and a mutual commitment to continuous improvement. Customers must also possess the expertise to interpret cost data and engage in effective, constructive negotiations.

Our Role:

Perpetual helps you set up open-book frameworks, mediate supplier discussions, and ensure that both sides benefit from the transparency. We bring the expertise needed to turn shared data into shared success.
