Does DeskOps ask my customers for reviews?

Two ways, both with your Google review link — paste it once at Settings → Email settings → Ask for a review. Request review on a customer sends a short note the moment you tap it. Automatic review requests go out only if you switch them on; then a customer gets one note about four hours after their job is finished — never twice within ninety days, and never about a job older than two weeks. A customer with four jobs this month is a good customer, not four chances to ask.
