I love your eagerness to get started with your QuickBooks Online Accountant ProAdvisor profile! It's an excellent way to connect with new clients and to have your current clients help build confidence in your service by leaving reviews. I'd be happy to go over this with you.
I can appreciate how hitting the ground running by being able to have reviews already ready once your profile is live. At this time, that's not an available option. Not to worry, once the profile is published, your existing clients will be able to leave you a review.
Here are some helpful articles to make sure the profile publishing process goes as smoothly as possible.
