Discover step by step how to use Diamontis FX for every invoicing situation.
As soon as you connect, your supplier invoices arrive automatically in your Diamontis FX workspace, via the Registered Platform - the PA, formerly known as a "partner dematerialisation platform" or PDP - and the DGFiP central directory.
Enter your invoice line items, choose the recipient from the directory and send your invoice in Factur-X format via the Registered Platform, in just a few clicks.
Already have an invoice in PDF? Upload it: Diamontis FX automatically extracts the key information, lets you validate it, then sends the invoice in the required regulatory format.
Every invoice goes through standardized statuses (AFNOR XP Z12-012). Diamontis FX displays them in real time and lets you act on the ones that concern you.
The Fichier des Écritures Comptables (FEC) is the regulatory format defined by article A.47 A-1 of the LPF (French tax procedures code), required during a tax audit and used by all accounting software.
The guided 4-step sign-up sets up your account and your tax settings, selects your plan, and activates your connection to the PA via a timestamped designation mandate.
Already under a mandate with another provider (PA or OD)? Switching to Diamontis FX is entirely possible, and we guide you through a seamless transition.
