Since webshop orders generally only have a customer and no debtor, these (sales) orders cannot be posted on account by default.
To make this possible, a “fallback debtor for paid deliveries” must be set in the webshop configuration.
This is a standard internal debtor, for example named “webshop debtor” or similar.
It is recommended to tick the option “never generate invoices” for this debtor, as this is not required for the deliveries.
The debtor can be set in the webshop configuration via Administration > Webshops on the “Orders” tab.

Using the option “generate deliveries on account from reservations,” the desired reservations can then be selected and processed into a delivery on account by choosing “generate deliveries on account.”
The generated deliveries on account retain the original customer of the webshop order, but the previously created debtor is used.
