If I want to test the invoicing flow for several months later, how the correct way to move forward the date and what should I do with whmcs system itself?
Maybe I just need change the server date to the specific event date and run the whmcs cron or I need move the server date day-by-day with whmcs cron run. Which one is correct ?
Or maybe there's a better way to do that, please advice. Thanks.
