This is the most operationally critical step — and the one most often left too late. Once your electronic address(es) are registered, your suppliers need to update their own PA routing settings to send invoices to your new address. This does not happen automatically.
What to communicate to each supplier:
Your SIREN-based electronic address (e.g.
123456789or123456789_EXPENSEREPORTS)The fact that they must route future invoices via their own certified PA using this address
That standard PDF invoices sent by email will no longer be compliant once the mandate is active
Tips for doing this efficiently:
Prioritise your highest-volume suppliers first
Include the electronic address in your standard purchase order or payment terms template
For expense-related suppliers (hotels, travel agencies), brief your employees to provide the correct address at the point of purchase
You can also used the templated provided below.
Brief your employees and approvers
E-invoicing affects more than just the AP team. Employees who submit expense reports and use company cards also need to understand what changes and what they need to do.
What to communicate to employees:
When making purchases from domestic B2B suppliers, provide your company's electronic invoicing address so the supplier can route the invoice correctly
For expense report purposes: the invoice must be put in the company name (e.g. a hotel stay billed to the company), the invoice should arrive via the PA network — not as a PDF by email
The Spendesk approval workflow itself is unchanged — approvers continue to work in the same place, with invoices arriving pre-filled
What changes for approvers:
In-scope invoices will arrive in Spendesk pre-filled with structured data — no manual data entry required
Approving, refusing, or querying an invoice in Spendesk automatically triggers the correct lifecycle status back to the supplier and the PPF — no additional action needed
A visual indicator will identify invoices received via the e-invoicing network
