Our approach to developing websites is strictly practical. We don't want to sell a client an endless supply of fish - we want to sell them a high quality fishing rod, so they can do their own fishing. That might make less money for us in the short-term, but after more than a decade in the internet industry, we know it stands us in good stead in the long-term.
Over the years we have built up a huge variety of tools and applications. When we talk to a potential new client, we generally point to what we have done, rather than what we theoretically could do. Developing and adapting something that already exists is a lot lower risk for a client than being an unwilling guinea pig.
