# Overview
> Learn about electronic invoicing compliance in Hyperline
## What is e-invoicing?
E-invoicing, or electronic invoicing, is the process of sending bills and invoices digitally between buyers and sellers. This topic typically involves a standardized format that allows invoices to be issued, received, and processed automatically by the involved parties' financial systems. This standardization is crucial for compliance, especially in regions like the European Union, where certain standards for e-invoicing are mandated.
## Support in Hyperline
Hyperline is **compliant with the e-invoicing standards** of the European Union, meaning it can generate valid invoices in both PDF and XML formats, and automatically transmit issued invoices to the appropriate tax authority in the invoicing entity's country.
Hyperline is proactively integrating this compliance into its product foundations by partnering with a third-party being compliant with local requirements to offer this service in each country as the e-invoicing mandate becomes mandatory.

### France
France is rolling out its e-invoicing mandate in **two phases**. From the first phase, every company established in France must be able to **receive** electronic invoices, while the obligation to **issue** them is staggered based on company size. Hyperline is concerned with the issuing part of the mandate.
Invoices must be transmitted through a certified **Plateforme Agréée (PA)** in a structured format (Factur-X).
| Phase | Date | What | Who |
| ----------- | ------------ | --------------------------------------------------------------------------------- | ---------------------------------------------------------------- |
| **Phase 1** | Sept 1, 2026 | Mandatory **receiving**: all French companies must be able to receive e-invoices. | **All companies** established in France (regardless of size) |
| | Sept 1, 2026 | Mandatory **issuing** and **e-reporting**. | **Large** companies and **mid-sized** companies (ETI) |
| **Phase 2** | Sept 1, 2027 | Full rollout: mandatory **issuing** and **e-reporting**. | **Small and medium enterprises** (SMEs) and **micro-businesses** |
Hyperline is already connected to **Chorus Pro** for B2G invoices and is partnering with a certified **PA** to cover flows ahead of the respective deadlines.
If your company generates **less than €50M** in annual revenue (SME or micro-business), you will be concerned by this reform for **issuing** starting **September 2027**. You must still be able to **receive** e-invoices from September 2026.
## Activation
If your country already requires this standard, you can activate this capability in your settings.
Some systems require pre-registration before starting the automatic
transmission of invoices. Click on the **Add credentials** button to
provide the necessary information.
You can then follow the status of the transmission for each invoice in the invoice details page.
If automatic transmission is disabled for an invoicing entity, invoices will show a "Not supported" transmission status instead of tracking the transmission progress.
## Customer notification
When e-invoicing is enabled and the invoice is eligible for automatic transmission, the ["Invoice to pay"](../../getting-started/emails#customers-automated-emails.mdx) email notification is not sent when the invoice is issued, but only when the invoice is actually transmitted to the e-invoicing system.
This email indicates to the customer that the invoice has been transmitted and is ready to be paid.
