How is the dunning schedule determined when a manual collection invoice is converted to automatic?

Dunning allows you to create custom configurations based on the collection method. Manual invoices are generated without any collection attempt. If enabled customers can pay manual invoices online via the Hosted Invoice Page. In order for the system to attempt collection with the provided billing method the invoice must first be updated to automatic collection.

If the collection attempt is unsuccessful, the invoice will move or remain in a past due state. However it will now follow the automatic collection dunning schedule. Our dunning references the number of communication attempts that have been sent and not days or a length of time. The time remaining will depend on the number of dunning communications prior to converting.  

For example:

Both your automatic and manual collection dunning schedules are set to send out eight communications. If the customer attempts an automatic collection via the Hosted Invoice after the fourth email sent from the manual collection schedule, the customer will enter the automatic collection dunning schedule on the fifth communication. They'll continue the dunning schedule for the remaining three communication prior to following your End of Dunning settings.
