Hi there,
I know how important it is to be able to adjust your vacation policy or pay out vacation time in QBO. It sounds like you're trying to pay your employees with their accrued hours. I'd be happy to point you in the right direction for support.
Based on your question, it may be best for you to reach out to our tech support team for help with this. Depending on how your account has been set up, you may not need to change the vacation policy in QBO, but rather submit a pay run using accrued vacation time.
With a few more details, such as which version of payroll you have, as well as how you've set up your employees and what's appearing in the Vacation Liability account, I'm confident our tech support team will be able to provide the best answer for you.
The Community is a great place to ask general how-to questions and share ideas with other users, however for more account-specific steps it's always a good idea to speak to an agent directly. The steps may vary for each individual user and account, and I'd hate to lead you astray.
I hope this helps get you on the right track.
Have a great day.
