Cash flow modelling has been the focus of different IT systems. These IT systems were largely developed to forecast and/or manage cash flow. However, cash flow models that consider the potential payment method are hardly dealt with in IT systems. Payment methods in this context relate to the processes by which construction products and services are priced and paid for. Alternative payment methods (e.g. incentive based, milestones, stage payment) are emerging but it is not yet fully understood how they should be implemented and what are their advantages and disadvantages in general. This research focuses on approaches that will encourage best practice and help facilitate project stakeholder satisfaction. As such this research aims to make a significant step forward from previous cash flow research that has typically focussed on forecasting and managing cash flow of projects adopting the standard approach of interim progress measurement. An IT system for payment methods in construction is to be developed to promote its use as performance enabling mechanisms. This will require identification of the available payment methods in terms of their supply chain links and pricing systems. This paper describes the development and the architecture of the proposed IT system. The system is intended to help industry practitioners in selecting the most appropriate payment method for given sets of project requirements and characteristics. The system will act as an aid to design or "fine-tune" payment methods to individual projects characteristics and needs. It can also be used by projects' stakeholders to forecast and plan their cash flow once a payment method is defined.
