QDV allows you to more effectively control costs, anticipate margins.

Our History

In 1991 a group of cost-evaluation experts designed an estimation software. They marketed this software as Quick Devis™. In 2010 the estimation software was rebranded as QDV™. QDV was designed to offer the complete estimation solution. QDV has the ability to adapt to your needs be it for a tender or a quotation.

QDV is a precise, analytical tool, which is both flexible and intuitive, and which has been designed to respond to your most demanding requests. You can present your costs exactly as you wish, and still retain total control over your margins!

QDV are more than just an exceptional piece of software. QDV offer our users and our partners all the support and training they need to make QDV work for them. This support is a little like insurance, you won‘t always need it as QDV is so easy to use, but it offers peace of mind knowing that it is there if you do need it.
