Studio Ninja is rolling out e-invoicing across the European Union in phases. The rollout will begin with Belgium in late 2025, followed by other EU countries including Spain, Italy, Poland, France, and Germany.
1. Connecting to the Peppol Network (powered by Storecove)
To support compliant e-invoicing, Studio Ninja connects to the Peppol Network via our certified access point partner, Storecove.
What is Peppol?
Peppol is an international e-invoicing network that enables businesses to exchange invoices in a standardised, government-approved format. Connecting to Peppol allows you to send invoices that meet strict legal and regulatory requirements across the EU.
Who is this for?
Customers and businesses operating in the European Union
Belgium-based customers will be the first to gain access, starting 29 December 2025
Your company country must be set to Belgium under Settings → Company Details to access the integration
If you are located in another EU country (such as Spain, Italy, Poland, France, or Germany), we recommend staying up to date via our email newsletters or Facebook Group for future release announcements.
How to enable the integration
Go to Settings → Integrations
Select the Peppol integration and click Connect
Follow the guided setup wizard to register your company
Important: Your registration via Studio Ninja is Sender-Only. This means you can send compliant e-invoices created within Studio Ninja to your business clients. This integration does not support receiving e-invoices from your own suppliers or third parties into Studio Ninja.
2. Registration and verification
To ensure legal compliance, all businesses must complete a multi-step registration and verification process before sending e-invoices via Peppol.
Registration steps
Welcome – An introduction to the process and requirements
Registration – Submit your company details as a legal entity
Verification – Confirm and verify your identity
A. Company details matching
When you begin registration, Studio Ninja will pre-fill the form using your existing Company Details.
Important:
The information entered during registration must exactly match your main account settings.
If you update your company name or address during registration, you will be prompted to update your Company Settings to keep everything aligned.
Mismatched details may delay or block verification.
B. Identity verification (via Stripe)
The final step is identity verification through Stripe, which helps protect the Peppol Network from fraud.
To complete verification:
You must finish the required Stripe account checklist
Your Legal Name, Business Name, and other submitted details must match the information on your Stripe account
Required information may include:
Country
Legal name
Business name
Government-issued ID verification
Verification status
You cannot send e-invoices until verification is complete.
If verification is incomplete or fails, you’ll see a status such as “Verification Required” or “Connection Failed”, prompting you to retry.
3. Sending e-invoices via the Peppol Network
Sending an e-invoice via Peppol is different from emailing a PDF. It is an official, regulated transmission of invoice data to a government-monitored network.
Important notes
Peppol e-invoicing applies to B2B invoices only
Consumer (B2C) invoices are not sent via Peppol
Sending options
Once your account is verified and connected, you may see the following options when sending an invoice to a business client:
Send via Email and Peppol Network
Send via Email only
Send via Peppol Network only
If your client is an individual (not a registered business), invoices will continue to be sent via email, with a link to the Client Portal and a PDF attachment. These invoices will not be sent through Peppol.
Locked invoices: no editing or deleting
Once an invoice is successfully sent via Peppol, it is immediately locked.
You cannot edit or delete the invoice
This ensures compliance, as the invoice has already been registered and received by the recipient’s system
Correcting mistakes with write-offs
If an error is made on a Peppol invoice, it cannot be deleted. Instead, you must issue a write-off.
Full write-off – Cancels the invoice entirely
Partial write-off – Adjusts part of the invoice amount
All write-offs are recorded in the invoice’s History Log, ensuring a complete audit trail.
Stripe surcharges and tipping is disabled
When the Peppol e-invoicing integration is enabled, Surcharges and Tipping in your Stripe settings will be automatically disabled.
This is because e-Invoices must reflect the exact amount billed to the client. Variable charges added outside the invoice structure (such as tips or surcharges) are not permitted under Peppol compliance rules.
