As a developer, what services do you offer? Web development, presumably, but do you offer anything else that will make your clients realise the true value of your company?

Many web developers choose to specialise in just that, web development. They complete a project, sign it off and move onto the next client.

Not only does this limit your value, it also limits your client base because not all companies want a website designed from scratch. Many companies just need to update existing sites, or they need someone to fix a problem that suddenly occurs.
