My stance on those is the "happy message" after a job is complete is the best report card. Before you send an invoice, ask them how everything went? If they say something like "ok" or anything but it went amazing, legitimately ask if there's something you can do better. That will do more to actually move the needle in your business than an arbitrary number.
Also, some people won't leave google reviews because they already gave you 5 stars on your internal survey.
What we do, is we have an automation through Go High Level, that asks them to rate us on a scale of 1-5 stars, if they click anything less than 5, it sends us a notification to reach out right away. If they give 5, it automatically sends them to our google business page to leave a review.
