Looking for ways to help you save time and effort is a great idea and getting your credit card provider added is one way to do just that. I'd be happy to help you with getting your provider added.
Syncing your credit card account to QuickBooks Self Employed is a great way to help you save time so you can focus on other parts of your business. Before requesting your credit card account be added there are a few steps to try and find out if the provider is already added. I recommend looking over this article for ways to search for it. After following those steps you can request it be added by following these steps:
Select the profile ⚙ icon and then Bank accounts.
Type your bank into the search box.
Select Request support for your bank.
Enter the bank name and URL.
Select Request.
If you have any questions let me know and I'd be happy to help.
