What is PA as a Service? Qonto is a certified Plateforme Agréée (PA) - an approved platform in the French e-invoicing network mandated by the 2026 reform. As part of this network, Qonto can route structured electronic invoices between businesses on their behalf. PA as a Service (PAaaS) lets your invoicing software plug directly into Qonto’s PA via API. Your users keep generating invoices in your tool - Qonto handles the transmission through the e-invoicing network. No Qonto interface, no workflow disruption.Documentation Index

How it works The integration follows three steps:
- Your user creates an invoice in your tool, exported in one of the supported structured formats: Factur-X (recommended), UBL 2.1, or CII.
- You upload the invoice to Qonto via the API. This registers the invoice and returns a
client_invoice_id. - You send the invoice via Qonto’s PA using that
client_invoice_id. Qonto routes it through the e-invoicing network to the recipient’s platform.
Coming soon: webhooks so you can be notified of supplier and client invoices’ lifecycle events
Account setup Each of your users needs a “Qonto PA” account (free, €0/month) to be registered as a PA user. This lightweight onboarding can be triggered programmatically - see Create a registration for the full flow, including the PA-specific account configuration.
