"INTUIT PYMT SOLN TRAN FEE" x ($10) charge to an invoice paid via bank transfer. Can see a second one being processed (same wording/amount). What are these for?

Hi there, @pao-lorant. 

The description “Intuit Pymt Soln Acct Fee” indicates transaction fees for the Intuit Payment Service. You pay a rate per ACH bank transfer. This also includes card swipes. The rates are as follows:

• Bank transfer 1% (max $10)
•  Card – Swiped - 2.4% + 25¢
•  Card – Invoiced - 2.4% + 25¢
•  Card – Keyed - 3.4% + 25¢

For more info, refer to this article: What are the fees for QuickBooks Payments?

To get detailed information about the charges that you received, I recommend contacting the Merchant Services Department. They can take a closer look at your account and verify these charges.
