My existing list of vendors won't show on the app when adding an expense, (but it is there on the computer.)When I select "who you paid," only customers show up. Ideas?

Hello @compositecarpent, Welcome to the Community! I appreciate the app troubleshooting you've done so far.

Since you have already updated the app, let's try refreshing it by clearing the cache data. A full cache can cause the application to behave abnormally.

For iOS devices:

1. Go to your phone's settings.
2. Select General, then choose iPhone Storage.
3. Tap QuickBooks Online from the application list.
4. Select Offload App to free up the storage without deleting the documents and data for the app.

For Android devices:

1. Go to your phone's settings,
2. Choose Apps (varies by device).
3. Select QuickBooks Online from the application list.
4. Go to the Storage section, then tap Clear Data.

After performing these steps, power cycle your device. If the issue persists, uninstall and then reinstall the app. If needed, you can also access QuickBooks through your phone's browser to manage vendors and transactions.

Additionally, please refer to this article about managing your bill in the app: Pay and manage bills with the QuickBooks Online mobile app.

If you have any further questions regarding your vendor list, please don't hesitate to ask. I'm always available to assist you. Stay safe!
