How to balance now??

Question

Hi I have a small issue now.
There are some invoices generated in bulk for customers due to running of some cp by mistake. The invoices which have 'direct debit' payment method went to bank for payment and the amount was collected(debited) from the customer accounts. In out application, once the DD is sent, the same day a receipt will be created as well against that invioce.
Now, what steps needs to be taken to return the amount back to the customers?
my assumption here is to
1) un apply the receipt and create refund to the customer - Here , I need to check whether the customer exists as supplier in AP or not, if not again I need to create that customer as supplier in AP. The customer count is around 200+, so its a time consuming process. Could you suggest simpler approach on this?
2) once step 1 is complete, as the invoice is back to Open status, we need to create adjustment to that invoice - this can be done through API. this we know.
Can you guys suggest me if you have any other ways of balancing the accounts here?
Thanks in Advance,

Depends how do you want to pay your customer back. If you can manage the payments within AR, use miscellenous receipts.
- Unapply receipt
- Create debit memo (with clearing account) and apply the receipt
- Create misc. activity with same clearing account
- Create misc receipt
For tracking, you can define special transaction type for debit memo.
