I can guide you through how to apply those payments to your invoices, narayan-bevara-o.

You'll have to enter the actual amount paid for the invoice and then create a deposit from that payment where you can deduct the charge as a negative amount. 

Let me show you how: 

1. Click + New, select Receive Payment.
2. Tick the checkbox next to the invoice you would like the payment to be applied.
3. Select Undeposited funds as the deposit to account.
4. Choose Save to record the transaction.
5. Go back to + New, then Bank Deposits. You should see the payment you entered in the Select Existing Payments section at the top.
6. Place a checkmark to select the payment you want to deposit.
7. From the Add funds to this deposit section, enter the fee charged to you as a negative amount.
8. From the Account section, select the Expense account you use to track these fees.
9. Verify that the deposit amount is correct.
10. Click Save.

You can then categorize and match your transactions in QuickBooks Online.

When everything is set, you can reconcile your account to keep your books updated. You can check this article for detailed instructions for the reconciliation process: Reconcile an account in QuickBooks Online.
