Manual review requests happen when the owner remembers. Automated review requests happen every time a job is marked complete. The difference is measured in dozens of reviews per year.
How to do it without feeling pushy
Time the request to the moment the homeowner is happiest - usually 24 to 48 hours after project completion. Keep the message short, personal, and easy to act on. Route negative feedback privately so it can be handled before it becomes a public review.
