I am using QuickBooks online. According to this KB article the fee should be 2.9% 0.25: https://quickbooks.intuit.com/learn-support/en-us/help-article/bank-transactions/fees-quickbooks-pay... However according to my calculations I am getting charged 3.4% 0.25 Here's an example: Customer invoice is $55 55 x .029 = $1.595 0.25 = $1.85 However for this invoice, QuickBooks charged me $2.12 not 1.85. When you do the math, comes out to 3.4% 0.25: 55 x .034 = $1.87 0.25 = $2.12 Why. I picked my last 8 invoices that customers paid online and they are all coming out to 3.4%
