As a guest supplier on the portal, before you can send an invoice by email, your customer must have configured this service.

To find out if your customer offers email delivery, and to obtain the email address for reception, view this information in the customer file:

• Customer menu
• Select the customer
• The "Possible transmission modes" field must contain "Mail"
• The email address for sending invoices by email shows the address to which you should send your invoices

By default, all users of your company who are registered on the portal can send invoices by email from the email address entered in their user account.

Some exceptions:

• If you have declared establishments for your company, it will no longer be possible to send an invoice by email.
• If a user has authorisations for several companies, it will not be possible to send invoices by email.

SY allows you to configure a dispatch email address that is different from the users’ email addresses, should you wish invoices to be sent directly by your billing system or other servers (Companies menu, Company tabs).
