Hi Stephan,

i'm about to start building! Can you sketch your situation especially on the payment side.

Customer Flow:
1. Fill Cart
2. Checkout with agreement of a Direct Debit
3. Order: status? state? ... we need a few status like pending, denied, retracted, credited?, final credit. (Customer can retract a payment next 3 weeks in The Netherlands)
4. When to send order???

Payment Flow (dutch: clieop3.module)
Sending DDs
1. add debit line to batch
2. Prepare batch
3. Submit batch to bank (by hand through https shop owner bank account)

Receiving statuses
1. Get status (by hand ... shop owner bank account)
2. Update order status

Some imagery would be welcome. And can you please send your email for faster communication through my drupal contact page http://drupal.org/user/125814

Regards,
Clemens
