PDF, PNG, JPEG and ISDOC/ISDOCX (ISDOCs can’t be extracted in Rossum. They contain metadatas that are automatically loaded to wflow). Wflow can read and show all the ISDOC variants.

You can send ZIP files to wflow too. But they need to be not encrypted by a password and be sent by an e-mail! Files are automatically unzipped and appear as indiviual documents. The invoice must be an attachment to an e-mail.
