Jobber has a native (paid) feature to automatically send out reviews. We use NiceJob and integrate it with Jobber. We we close a job, NiceJob starts a campaign to ask for a review. It'll send one text and three emails over a course of the month. They stop getting communications when they click on the link I think.
Or, if you don't want to pay, you just need to setup an SOP to ask the customer if they can leave you a review and immediately send them a link directly to your Google Business Profile (or wherever you want the review). Then, if they don't, then follow up in two days. And then if they don't, follow up in 5 days. Etc...
