Customer paid invoice with credit card. Card company take 1.75% and pay rest into my bank account how do I record this ?

It's good to see you here with us, i-weedon,

Let me get the help you need in recording credit card fees for your paid invoice.

Upon receiving customer's payment, deposit the payment to Undeposited Funds and not the Bank Account. 

Once done, to record the charges, you'll need to create a deposit transaction and record the expense in a negative amount. Here's what you'll need to do:

1. Click the Plus icon (+) at the top.
2. Under Others, click Bank Deposits.
3. Put a check mark for the payment included in the deposit.
4. Go to Add funds to this deposit section, select customer then choose Credit Card Fees for the account
5. Enter a negative amount, under Amount.
6. Click Save and close.

That's it! By the following the steps above, you're now able to record credit card charges.

If there's anything else you need help with in managing your transactions, please let me know. I'd be happy to help. Have a great day!
