Construction Project Management Software Features - Prime Contract Invoice


Progress payments for the Prime Contract are processed in the Prime Contract Invoice feature. For commercial contractors, Prime Contract Invoices are commonly referred to as Application for Payments and follow the AIA Billing method (AIA G702 and G703). For residential contractors, Prime Contract Invoices are done for Bank Draws.

Preparation of the Prime Contract Invoice is, historically, a difficult and time-consuming task due to retainage (holdbacks) and calculating previous invoice amounts and what change orders have been billed or not. However, Corecon contains Billing Wizards that were designed to ease this burden dramatically.

To use the Prime Contract Invoice properly, it is important to understand the business process that transfers information from the Prime Contract into the Prime Contract Invoice. The table listed below explains the relationship between the Contract Type and Billing Method.
