I'm here to share some information about the different subscriptions in QuickBooks Online.
QuickBooks Online has Simple Start, Essentials, Plus, and Advanced versions. You can check this page to know what subscription works best for your company: QuickBooks Online Plans & Pricing.
As for the authorization amount, can you tell me more about it? What question do you have about it?
Also, feel free to visit our Help Articles page for some tips in managing your QuickBooks account.
I'll be around to keep an eye on your response about the authorization amount. Keep safe!
