I just got the mobile app. Do I have to also have the desktop version?
I hope you're having an awesome weekend so far! I love the QBO mobile app I find it to be extremely convenient! In regards to the desktop version did you mean a QuickBooks Desktop product such as Desktop Pro or Premiere or the QuickBooks Online Desktop APP?
If you mean the QuickBooks Online Desktop APP, for me personally I love to have it on my PC as a back up in the case I am having a browser issue and cannot log in through a browser for whatever reason. The QuickBooks Online Desktop APP was my saving grace to continue working on what I needed to get done and worked great when I needed it. I truly love having the flexibility to work either through the Desktop APP, Browser, or going mobile through the mobile APP.
If you were speaking in regards to Intuit QuickBooks regular Desktop products such as Pro or Premiere, I don't believe you will need two accounting software and I truly believe QuickBooks Online has everything you could possibly need to run your business.
I hope this helps! Have a great rest of your weekend!
