Are they charge for this app?

Hello there, Malith. I'll answer your query about the QuickBooks Online (QBO) subscription fee.

Your subscription fee will based on your QuickBooks plan or version. You can review each subscription level of QBO and its associated costs through this website: Pricing page. If you're referring to the QBO app that you can install on your mobile phones, it doesn't incur a fee as long as you subscribe to a QBO plan.
