I am wondering what the online invoice bill payment transaction fee will be if my client pays his invoice with VISA. Is there a standard percentage quickbooks charges ?

Hi there, 

Glad to have you join the Community. QuickBooks is a user-friendly platform that helps you receive payments from your clients with ease. I'll be happy to provide the information you need so you're on the right track. 

QuickBooks Online payments charges a service fee of 2.9% $0.25 per transaction per transaction. The taxes are already included in this transaction. I encourage you to learn more about the rates and breakdowns for using QuickBooks Online Payments using this link here.
