Go Cardless - bulk payments for multiple invoices

Suggested

HI

We have Go Cardless module linked to our Sage 50 Accounts which collects payments from our customers via DD. However, each invoice loaded to the customer account has one payment against it - for example one customer could have 15 invoices in one week, and they will have 15 individual DD payments deducted from their bank. This is causing our customers to become quite irritated and they are being charged bank charges for each transaction. 

Is there a way to bulk the invoices per customer in to one DD payment deduction? 

Go Cardless have told me that I need to speak to Sage as Sage handle how the information is passed to GC

Please let me know urgently any information as I need to get back to a few customers about this. 

Thanks

Donna
