QDV operates a multi-purpose API (Application Programmable Interface) and has a unique code editor which allows you to create forms, messages and code to read and write to any estimate or a database. It is open to major standards and can be interfaced into nearly any software or database engine. Similar to Office VBA but more flexible and faster since it relies on compiled languages C# and/or VB .NET. Any extension developed using the QDV code editor will be as efficient as if developed by the publisher. It truly becomes a part of the compiled program. Using it to configure QDV, you can build the exact industrial estimating tool you need.
