Does anyone know why i can no longer make received amounts on my credit card billable any more?

Hi there, @shannon34.

I'd like to know if you have encountered an error when trying to receive a payment. This will help me identify the issue and give you a specific resolution for this.

In the meantime, I'd suggest performing a browser troubleshooting steps. We're going to check if this is a browser-related issue.

Let's start by using an incognito browser while receiving payment in QuickBooks Online. If you can see that it has a billable amount, you can go back to the regular browser and clear the cache. If not, you can use other supported browsers as an alternative.

Here are the keyboard shortcuts to access a private window:

• Microsoft Edge & Mozilla Firefox: Ctrl + Shift + P
• Google Chrome: Ctrl + Shift + N
• Safari: Hold down ⌘ + Option + P 

I've also added this article to guide you in the future about the billable expense in QuickBooks Online: Enter billable expenses.
