I have mixed feelings about this, but that might just relate to a certain subset of SaaS products we've used - namely products that require heavy integration with your data. I'd sooner spend engineering time writing our own report generators than writing code to push data to another service, in the format they expect, pre-empting which data we might want to have in that service down the track, understanding exactly how the different reports are calculated, and then inevitably having to write a few custom ones of our own as well. Of course, the exception to this are services have a huge set of useful features and take basically no time to fully integrate with, like Google Analytics.
