As a Meta Ads agency we spent around 2h every month/client on reporting. We looked into Looker, but connectors either didn't support custom conversions or they broke every other day. We did manual csv exports until our marketing manager burnt out. OneClick Reports serves a single purpose. Less than 1 minute to create and schedule reports for your clients. Pick what you want to track (custom conversions included), set up a schedule for the report and start saving days worth of work every month.
