In order for an order to be imported (or exported), it must be marked as either "not paid" or "not sent" (in Jimdo).

If you have already gone through the order process in Jimdo and marked the order as "Paid", Jimdo will move that order to the "Archive" section. Once an order is in the archive, it can no longer be exported (this applies to both CSV/XML and automatic PamBill import).

Solution: mark the order as unpaid, import it into PamBill and mark it as paid again in Jimdo.
