I love TurboTax for my personal taxes, but the business edition is horrible. It lacks all the feature that make the home version convenient--inline explanations, detailed prompts to help you get the right information, contextual help within the application, AUTO SAVE (I had to start my deductions over again because it popped up a save window so fast that my mouse inadvertently clicked no before I could read the prompt)!
The help function in the business edition is worthless, it just takes you to the homepage where then you have to spend time figuring out what options to choose that will get you to the answer you need. My business is small and my taxes are pretty simple, but now that the business is growing, I am going to have to hire a CPA--which is ironic because the whole point of this software is supposed to be to make my life easier as things get more complex, not add to the complexity.
Your lack of integration with your own QuickBooks Online continues to be a MASSIVE disappointment - but it's not a surprise. You continue to charge insanely high fees (for both products) and provide poor service and desired zero upgrades.
