E-Invoicing for Garages in France : the Complete 2026-2027 Guide
Electronic invoicing is becoming mandatory for every French business, garages included — even those working only with private customers. This guide sums up what changes, on which dates, and shows step by step how MekaDesk handles everything: activation, sending invoices to your professional clients, and receiving your suppliers' invoices automatically.
What Changes, and When
The reform rests on a simple principle: invoices between businesses no longer travel by email or paper, but pass through platforms certified by the tax authority (Plateformes Agréées, PA), which check and route them. The timeline:
| Deadline | Obligation | Who is affected |
|---|---|---|
| 1 September 2026 | Receive electronic invoices via a certified platform | All businesses, even 100% private-customer ones |
| 1 September 2027 | Send invoices to professional clients electronically | Small and medium businesses |
| 1 September 2027 | E-reporting: transmit the totals of sales to private customers | Small and medium businesses |
Penalties apply for non-compliance (a fine per non-compliant invoice, capped per year). In practice, for a garage: from September 2026 your parts suppliers will send their invoices through this channel — so you need to be connected to receive them.
How MekaDesk Handles the Reform
MekaDesk builds e-invoicing directly into the app, with no extra software and no surcharge: your invoices are generated natively in the regulatory Factur-X format (PDF + embedded EN 16931 XML), and connecting to the certified platform, sending, tracking and receiving are all handled from the interface you already use every day — including offline.
It all comes down to three steps, detailed below.
Step 1 — Activate E-Invoicing
Activation happens once, from My Account → E-invoicing:
- Check your garage profile — your garage's SIRET must be filled in (garage profile); it identifies you in the national directory
- Click Connect — you are taken to the certified platform's onboarding tunnel: verification of your business and of the legal representative's identity (have an ID document ready, verification is done from your phone)
- Authorize MekaDesk — the final screen asks you to authorize MekaDesk to send and receive your invoices; you then return automatically to the app
- Choose your VAT regime — required by the authority for invoice routing
Once verification is complete, the section shows "Business verified — transmission active" with your national directory address. Your garage is compliant for the September 2026 deadline: it can receive electronic invoices.
Step 2 — Send an Invoice to a Professional Client
On every invoice for a business client, a Send button appears in the invoice list. Before sending, MekaDesk checks everything is in order and tells you exactly what to fix if needed:
- The invoice is final (not a quote or pro forma)
- The client is a business with its SIREN or SIRET filled in
- Your garage's SIRET is present in the profile
After sending, the regulatory status appears as a badge on the invoice and updates automatically:
- To send — requested offline, will go out when the network is back
- Sent / Received by the platform — the invoice is taken over and routed to your client
- Rejected — a check failed; the exact reason shows on hover, fix and re-send
Duplicates are impossible: if an already-accepted invoice is re-sent identically, the platform refuses the second submission. Margin-scheme invoices (used vehicles) cannot be transmitted in Factur-X format — MekaDesk flags this and you keep handing them over as you do today.
Step 3 — Receive Your Suppliers' Invoices
There is nothing to do: as soon as a supplier sends you an electronic invoice, it appears under Supplier purchases with an "e-invoicing" badge, when you open the app or when the network returns.
- The invoice arrives as a draft, with the supplier, lines, amounts and VAT pre-filled
- You review it, link the lines to your stock parts if needed, then validate it
- Only validated invoices feed your accounting exports — nothing enters your books without your review
- A deleted invoice does not come back, and no duplicate is created across your devices
Frequently Asked Questions
My garage mostly serves private customers — am I affected?
Yes. From 1 September 2026, every VAT-registered business must be able to receive electronic invoices through a certified platform, even if it only invoices private customers: your parts suppliers will send their invoices through this channel. Sending to your professional clients becomes mandatory in September 2027, and sales to private customers will be covered by e-reporting.
What must I do before 1 September 2026?
One thing only: be connected to a certified platform so you can receive your suppliers' invoices. With MekaDesk this takes a few minutes from the My Account page, without changing software or managing a separate account day to day.
How much does it cost?
E-invoicing is included in the MekaDesk subscription (€9.99/month or €99/year), with no per-invoice surcharge or paid add-on. Many tools charge for this service separately.
What is a rejected invoice and what do I do?
The certified platform checks every invoice (mandatory fields, SIREN, VAT…). If a check fails, the invoice comes back with a Rejected badge and the exact reason is shown in MekaDesk. Fix the flagged item (for example a missing SIRET) and re-send: the new submission replaces the old one.
Does it work offline?
Yes, following MekaDesk's offline-first design: if you click Send with no connection, the invoice is queued with a To send badge, then transmitted automatically as soon as the network is back. Received supplier invoices are fetched at the next connection.
Do my invoices stay normal PDFs for my private customers?
Yes. Nothing changes for private customers: they receive a standard, readable, printable PDF. The Factur-X format simply adds an invisible XML file inside the PDF, required by regulation for exchanges between businesses.
