Lately I’ve been looking at a number of SaaS providers covering a range of areas. It amazes me how many of them have no API or only a reporting API. If you’re thinking of building a SaaS start-up then you should be thinking about creating an API that allows your customers to do everything they can with your user interface.

Service providers with this API have an obvious advantage when it comes to migration and integration but they also have a more subtle and more important advantage. When reviewing potential providers I looked at those with an API before those without. Your SaaS may be the best but without this API are potential customers even considering you?
