Although ASPDotNetStorefront is overflowing with features, your requirements may go beyond the capabilities of the core platform, or you simply require non-standard functionality.
With many years of experience developing complex web applications, we are perfectly placed to make carefully planned and documented changes or enhancements to the core system.
An example is our work on the www.forgan.ca website. Our customer asked us to create a "Custom Fit Wizard". We deeply customised the core product to create features on the front end and the back end (product management, order management etc) to enable the custom fit features. Take a look at the website!
