Monthly fee, my husband downloaded the app and got a monthly fee of $19.90. How do I get the same price?

Hello there, Gabi. 

In QuickBooks Online (QBO), you can freely download its app version. Afterward, ensure to have a subscription or enter the same credentials you have in QBO. 

Regarding having the same price as your husband, it's currently unavailable. However, you can check out the website of QuickBooks Online to see their available plans and pricing, or you can click this link: https://quickbooks.intuit.com/pricing/.
