Do you require custom functionality for your website? A quotation system rather than online sales, a product builder where you can build and save as a quote or sell the finished product online.
You do!! Then using OpenCart functionality we can build this functionality for you and at the same time allowing you to manage your products and options through OpenCart's admin area so you have control of options, pricing in order to display and build the price of your product.
Every requirement is different and requires several discussions and wire framing to create a website that sells to consumers. B2B or both with great functionality for users.
See some sample below.
