Support is the weakest part of the experience. Simple questions get answered, but complex problems, broken bank feeds, migration issues, or anything involving a payments hold can take multiple contacts and inconsistent answers. The accountant-specific support channels are better than the general queue, and firms should use them, but 'better than the general queue' is a low bar.
In practice, experienced firms route around support. The ProAdvisor community, a good internal knowledge base, and a habit of documenting fixes get you further than the phone. That works, but it is worth naming plainly: part of what you are paying Intuit for, you end up providing yourself.
