It's nice to see you posting here in the Community forum, foyinvoice.
I'm here to share information on how QuickBooks handles security deposit payments.
If you processed a security deposit online using the QuickBooks Payments link to your QuickBooks Online account, specific fees will apply.
To get more information about the payment rates for QuickBooks Payments, you can visit this site: Standard Payment Fees & Rates.
In case you need to return a part of a security deposit, you can always refer to this article: Refund a security deposit in QuickBooks Online.
Feel free to get back here in the Community if you need further assistance related to handling security deposits. Just leave a comment below, and I'll be more than happy to help.
