In QuickBooks Online, you can enter your credit card charges as Expenses, rgkcdt. From there, you can select a category so you can post the amount individually. I'll show you through the process below.
Here's how:
Go to the + New icon and then choose Expense.
Choose the credit card account under the Payment account drop-down menu.
Select the credit card type under the Payment method drop-down list.
I also recommend performing regular reconciliations of your account in QuickBooks. This process helps ensure that your bank and credit card statements are accurate and match your QuickBooks records.
