    Why doesn't DEMO pay the fees?

    DEMO does not cover a Suppliers costs to produce your paper invoices and therefore will not be covering the cost to send electronically. However the electronic solution is more cost effective to most businesses. In addition to the financial savings you will also receive the advantages of immediate invoice submission, invoice delivery confirmation, and 24/7 invoice status and reporting capability.

    Will DEMO make payments using Tungsten?

    Tungsten is not a payment platform. DEMO will continue to use their current payment method.

    Can I send electronic invoices via the Tungsten Network?

    To start using the Tungsten Network, all you need to do is register now, using the Registration Key or TN Number given to you by your customer. Once registered, all suppliers using this option automatically receive 52 free transactions. At the end of your first anniversary (one year after registration), we will replenish your account, at no charge, back to 52 free invoices for you to use during the next 12 months.

    If you are registered in one of the countries below and intend to store your invoices for tax reclaim on the Tungsten invoice archive you will need to notify your local tax authority. Tungsten provides a standard wording you can use to provide this notification. A link to a copy of the notification template will be emailed to you.

    How secure is sending invoices via the Web Form?

    Access to the Tungsten service, including the Web Form, requires three credential authorizations. In addition, each session is protected by industry standard 128 bit SSL encryption using Class 3 Server Certificates from Verisign. Once your invoice is created it is stored in the secure archive where it is protected by the latest security measures which are tested daily.

    This means only authorized users can connect to the site and that once connected, all communications are private and data is completely secure.

Registration & Account Maintenance Questions

    Is registering on the Tungsten portal equivalent to joining Tungsten?

    Yes, part of the registration process is that you have to accept required standard terms and conditions given. Once you do it, the expectation from DEMO is that you will stop submitting paper invoices (rejected if still received) and submit all invoices via Tungsten.

    Do I need to enter into sign an agreement with Tungsten Network?

    Yes, regardless of the solution you choose, you will be required to accept Tungsten Network’s terms and conditions.

    Do I need to install any software?

    The Tungsten Solutions do not require any software or hardware installations to submit invoices.

    What are the minimum system requirements for using the Tungsten Network?

    The minimum operating system requirements are: Microsoft Windows 98 Second Edition, Linux or Mac OS 9.2*.

    Minimum browser requirements are: Version 9 of Internet Explorer and the latest versions of Firefox, Chrome, Safari and Opera.

    Can I send two invoices with the same invoice number?

    No, this is to prevent duplicate invoices. The system itself does not allow entering the same number twice.

    Can I send an invoice with an earlier invoice date than today's date?

    Yes, just enter relevant date. However, a future date is not possible.

    How do I add an attachment to my invoice?

    • As DEMO allows attachments, go to ‘Invoicing’ and select ‘Invoices pending attachments’
    • Find your invoice by adding the invoice number to the search field or sort the ‘Invoices awaiting attachments’ table by the various column headings
    • Check the allowed file types in the ‘Upload’ column
    • Click ‘Select’ to add the file(s) you want to attach on your computer
    • You can see your attachments in the ‘Attachment count’ column
    • You need to release your invoices with attachments to alert us that they are ready to be processed, tick the boxes by the relevant invoices and click the ‘Release’ button
    • If you have an invoice pending attachments then you will have 24 hours to add the attachments before the invoice is automatically sent

    Does the "Accepted" status on the Tungsten portal mean that my invoice has been accepted for payment by DEMO?

    No, to get an accurate status of your submitted invoices you should view the Invoice Status updates on your Tungsten portal account.

    When using Invoice Status with Tungsten, what type of invoice status updates will I receive on the Tungsten portal?

    • Sent: Your invoice is waiting to be validated by Tungsten system
    • Accepted: Your invoice passed Tungsten validation – invoice not yet received by DEMO AP Department
    • Failed: Your invoice did not pass Tungsten validation – please check most common mistakes before raising a ticket (e.g. PO range)
    • Delivered: Your invoice is ready to be transmitted to DEMO AP Department
    • Received: Your invoice was entered to DEMO AP Department’s system – it will be validated for correctness and processed
    • Rejected: Your invoice did not pass DEMO AP Department’s validation and was rejected – you will receive rejection information from DEMO EMAIL.
    • Approved: Your invoice was posted
    • Paid: Your invoice was paid
    • Exception: Your invoice is under DEMO’s investigation – you may be contacted for correction / Credit Note

    What if Tungsten doesn't accept my invoice number when creating an invoice?

    Tungsten remembers all invoice numbers sent by you to DEMO. This protects both you and DEMO from sending duplicates. Therefore your invoice should always have a unique number, for example 1/2016 and 1/2017 will be accepted.

    When I enter multiple PO numbers at the header level my invoices fail submission. Where should I enter this information?

    Please enter only one PO in “PO field” on invoice header. Please enter other POs in the body of the invoice – each PO on each related line, e.g.:

    • Line 1: first PO, description of the related delivery/service/goods
    • Line 2: second PO, description of the related delivery/service/goods
    • Line 3: third PO, description of the related delivery/service/goods

    Who is in charge of providing supplementary access of Tungsten Network login details for other users?

    When a supplier or Buyer registers to the Tungsten portal they have to nominate an administrator, the details of the administrator can be located by clicking on “My Account” and then by clicking on “My Profile” the details will appear at the bottom of the screen.

    It is the administrator that can add new users and amend access rights.
