  • Which suppliers can send me invoices?
    Suppliers must be registered in the system in order to send invoices to the xs collector. At least one e-mail address must be added on the "whitelist". This can be done in several ways:

    • When creating a supplier, an e-mail address is specified in the contact details. This is then automatically placed on the "whitelist" and the supplier can send invoices from this address.

    • If no e-mail address is specified when creating a supplier record, the supplier can only be registered if a contact with an e-mail address is specified.

    • There is also the possibility to activate a domain for a company with multiple employees allowed to send invoices. In this case, a „*” must be placed in front of the @ sign (*@crossinx.com).

6. Archive

  • Who can access the archive?
    All users with access to the xs collector portal can download the documents themselves and archive them locally.

  • How long will my documents be archived?
    Invoices must be stored in their original form for 10 years (extension to 11 years possible). crossinx offers the following document archiving options:

    • Short-term archiving - 3 months (included)

    • Long-term archiving - 11 years (additional charges apply)
