E-invoicing for a Shopify store in France: what actually changes in September 2026

The French e-invoicing reform starts on 1 September 2026 and the coverage of it has been unhelpful, because it collapses two separate obligations into one word. For a Shopify merchant the first useful question is not "what do I need to buy" but "which of the two am I in?"

Two obligations, not one

E-invoicing covers invoices between two businesses established in France. The invoice must be a structured electronic document — Factur-X, UBL or CII — and it must travel through an approved platform (plateforme agréée). A PDF attached to an email stops counting.

E-reporting covers everything else you sell: sales to consumers, and transactions with parties abroad. There is no document per sale here. You periodically transmit aggregated data — sales totals broken down by VAT rate — to the tax authority.

A typical Shopify store selling to consumers is in the second category for the bulk of its revenue, and in the first for the business customers it does invoice.

The dates

1 September 2026 — every VAT-registered business established in France must be able to receive e-invoices. Large companies and mid-size companies (ETI) must issue them, and start e-reporting.
1 September 2027 — SMEs, small businesses and micro-enterprises must issue e-invoices and start e-reporting.

Two things follow that are easy to miss.

The receiving obligation applies to everyone in 2026, whatever your size. If you are a one-person business in France, you are not issuing e-invoices next month, but your suppliers may be, and you have to be able to receive what they send. That means being reachable on a platform, which is an administrative step, not a software project.

The issuing deadline for most Shopify merchants is 2027, not 2026. If you are a small business, you have a year more than the headlines suggest. That is not a reason to do nothing — it is a reason not to buy in a panic.

What this means concretely for a Shopify store

If you only sell to consumers in France

E-invoicing does not apply to those sales. E-reporting does, from your size's date. What you need is a way to produce the periodic aggregated declaration, which is an accounting question more than a Shopify one — talk to whoever files your VAT returns, because the data comes from the same place.

If you also sell to businesses

Those invoices are in scope. From your date, they must be structured documents passing through an approved platform. Two components, worth separating because they are sold together and are not the same thing:

Producing the document in the right format, with the right content, with a valid number. This is where an invoicing app sits.
Transmitting it through an approved platform to your customer. This is a platform service, chosen from the list the tax administration publishes.

Being straight about it: InvoicePilot does the first. It produces the Factur-X PDF — readable as a PDF, machine-readable as EN 16931 XML inside it — with a gapless series and the mandatory content. It does not transmit to a platform today. Anyone telling you a single €9 app makes you compliant end to end is selling you half a thing and calling it whole.

If you sell abroad

Cross-border transactions fall under e-reporting, whether the buyer is a business or a consumer. The intra-EU B2B invoice itself still needs the buyer's VAT number and the reverse charge mention, which is not new and is covered in the VAT invoice guide.

Four things worth doing before September 2026

1. Work out which category your sales fall into. Split last year's revenue into domestic B2B, domestic B2C, and abroad. That single table tells you which obligation hits you and roughly when.

2. Find your size bracket. ETI and above start issuing in 2026; everyone else in 2027. Most Shopify merchants are in the 2027 group and are quietly being sold 2026 urgency.

3. Fix your invoice numbering now. Whatever platform you eventually use, it will expect a valid, continuous series, and no tool can retroactively repair one built on Shopify order numbers. This is the cheapest thing on the list and the one that gets deferred. See Shopify invoice numbering.

4. Start collecting buyer VAT numbers properly. You need them for the B2B invoices you are already issuing, and validated ones are what make the reverse charge stand up. Doing it at the moment of sale costs nothing; reconstructing it a year later costs a week.

What not to do

Do not buy a platform subscription in August 2026 because a newsletter told you the deadline is next month, when your issuing date is a year later and your first real obligation is to be reachable. And do not assume your accounting software already covers it: ask them directly whether they will be an approved platform, and get the answer in writing.
