Hi rachel34,
Thanks for your post, we'll help you get this mandate active and working in QuickBooks.
First, can we check if you created this mandate for your customer from within QuickBooks or by importing an active mandate from GoCardless?
If this was set up within QuickBooks, has your customer received the email and approved the mandate?
