This sounds great, however, when i go to settings, account & settings, and click on the expenses tab, the option to turn it on is not there:

Thanks for providing us a screenshot, @Ringwaldt.

The steps above only works when you have QuickBooks Online (QBO) Plus. If you want to avail of the Billable expenses option, you'll want to upgrade to QBO Plus. Let me guide you how.

In your QBO account:

1. Go to the Gear icon.
2. Select Account and Settings.
3. Go to the Billing & Subscription section.
4. Select Upgrade your plan.
5. Follow on the onscreen instructions to finish the process.

However, if you don't want to upgrade to QBO Plus, you can try our free (30) thirty days trial. This way, you can try and see if this version of QBO suites your needs before upgrading. Don't worry though, our free (30) thirty days trial is 100% percent free.
