How many credit cards can i have for my business, i have basic QB online

Hello @emily-livenouris,

Let me share some information about the number of credit cards you can have for your business.

To start with, if you're referring to the credit card account for your subscription, you can only enter a single credit card information for billing. You can consider checking out this article to learn more: Update the payment information for your subscription.

But if you're meaning to create a credit card account, it is base on the number of all your accounts in your Chart of Accounts. Since you have subscribed to the basic plan or Simple Start, you can have a total of 250 number of accounts including those already created accounts. 

In addition, here's an article you can read to learn more about the number of accounts you can create: What are usage limits in QuickBooks Online?

Lastly, I've got you this helpful article in case you need the steps in case you start accepting credit card payments from your customers: Process a credit card payment in QuickBooks Online.

If there's anything else that I can help you with, let me know in the comments or post again. I'll be here to help.
