✓ Compatible Solution, Pennylane Approved Platform
DeviStor + Pennylane: your Factur-X invoices synced with your Approved Platform
Create your quotes and invoices in DeviStor. They are sent automatically to Pennylane, your registered PA, for effortless 2026 compliance, with no double entry and no manual export.
Why connect your invoicing software to an Approved Platform?
The e-invoicing reform requires every French company to designate an Approved Platform (PA) in the central directory. From September 2026, every company must be able to receive electronic invoices via its PA, and not having one registered is sanctioned. Issuing e-invoices becomes mandatory for SMEs and micro-businesses from September 2027.
In practice: your quoting and invoicing software needs to talk to a PA. That's exactly what DeviStor does with Pennylane.
This official status, as part of the Pennylane partner program, guarantees that the integration is built on the Pennylane API and maintained over time, not a hack that breaks at the first update.
How it works, in 3 steps
Connect Pennylane in one click
In DeviStor, click "Connect Pennylane". You authorise access via OAuth 2.0 directly in your Pennylane account. No Pennylane password is ever entered or stored in DeviStor, access tokens are encrypted (AES-128) and revocable at any time.
Create your quotes and invoices as usual
Quotes signed online, deposit invoices, construction retention, credit notes, your whole workflow in a simple interface. On finalisation, DeviStor generates a Factur-X COMFORT invoice: a PDF/A-3b with embedded EN 16931 XML, verified at 0 errors.
The invoice is sent to Pennylane automatically
Every finalised invoice is synced to your Pennylane account, your Approved Platform. No more manual export, no double entry, no PDF to forward to your accountant: the data arrives exactly where the reform requires it.

DeviStor + Pennylane vs. standalone invoicing software
Many quoting and invoicing tools are not connected to an Approved Platform. As a result, you'd have to manage transmission of each invoice to a PA yourself, or switch tools before the deadline.

Frequently asked questions, Pennylane integration
What is a Pennylane Compatible Solution?
A Compatible Solution is software officially connected to the Pennylane Approved Platform as part of its partner program. DeviStor has signed this partnership: Factur-X invoices created in DeviStor are transmitted to Pennylane, your registered PA, which handles regulatory routing and archiving.
Do I need a Pennylane account to use DeviStor?
For automatic synchronisation to your Approved Platform, yes, your Pennylane account serves as your PA. If you haven't chosen a PA yet, DeviStor also works standalone: you create compliant Factur-X quotes and invoices, and you can connect Pennylane at any time.
How does DeviStor connect to Pennylane?
Via OAuth 2.0: you click "Connect Pennylane" in DeviStor, you authorise access in your Pennylane account, and that's it. No Pennylane password is ever stored in DeviStor. Access tokens are encrypted (AES-128) and the connection can be revoked at any time.
Are my invoices compliant with the 2026 reform?
Yes. DeviStor generates invoices in Factur-X COMFORT format (PDF/A-3b with embedded EN 16931 XML), verified at 0 errors. Sent to Pennylane, a PA registered by the DGFiP, they meet the reform requirements: mandatory reception for all companies from September 2026, issuance for SMEs/micro-businesses from September 2027.
What happens if I switch Approved Platform?
Your data stays in DeviStor: customers, quotes, invoices, catalogue. The Pennylane connection can be revoked in one click. Your Factur-X invoices remain compliant and exportable, you're never locked into the integration.
