Thanks for joining this conversation, @2kids2dogs.

The account number entered in the vendor details should show in the memo of all payments. Since you're unable to see it, let's try some troubleshooting steps to help isolate this.

To start, try logging into your QuickBooks Online (QBO) account using a private browser (incognito). There are times that the browser is full of frequently accessed page resources, causing some unusual responses.

Here's how:

• Press Ctrl + Shift + N (Google Chrome).
• Ctrl + Shift + P (Firefox or Internet Explorer).
• Control + Option + P (Safari).

Once signed in, write a test check again. If it works, return to your default browser and perform a clear cache. Every so often the cache becomes overwhelmed with older data which can potentially cause viewing and performance issues.

Clearing it will refresh the system, and you'll be able to work with a clean slate. However, if the issue persists, try using other supported browsers.

Please reach out to me in the comment section if you have any other issues or concerns, and I'll get back to you. I'm always here to help. Have an amazing weekend!
