Transmitter data on the e-invoice

Goal

Fill in, if needed, the transmitter data: the party that physically sends the XML file to the Sistema di Interscambio (SdI), which can be the company itself or an intermediary acting on its behalf.

Prerequisites

• Initial setup wizard completed (see first-installation).

Steps

1. Go to POP → Electronic Invoice - Settings, General tab, Transmission Data section.
2. Fill in, if relevant to your case, the fields (all optional):
   • Transmitter ID — VAT number of the transmitter/intermediary.
   • Transmitter Phone number.
   • Transmitter email address.
3. Save.

If you leave everything blank, the transmission channel in use will apply its own default values (e.g. its own data as the direct transmitter).

Verify

Generate a test document and check, in the generated XML, that the transmitter data block reflects the values you entered (or stays empty/default if you didn’t fill them in).

Common errors

• The fields appear disabled/not editable — after completing the wizard and connecting the account (active license), the company and transmitter data in General become read-only in wp-admin: any further changes must be made from the POP account panel, not from here.
• You use the Aruba add-on or another channel that acts as an intermediary on your behalf — in that case the channel can manage its own transmitter data independently (e.g. its own tax code as an authorized intermediary): check the specific documentation for the active add-on/channel, since it can differ from what’s configured here in the General tab.
• You’re not sure whether you need to fill in these fields — if you don’t use an intermediary for sending (e.g. you send via SdI via POP directly as the company), you can leave them blank.
