Shopify Invoicing: what you absolutely must comply with to be compliant (France / EU)

This is a topic that often makes people roll their eyes 😅
Invoicing, especially when selling on Shopify.

In real life, what I often see:

• stores that sell well,
• orders piling up,
• and… invoices that are not really compliant (or non-existent).

👉 The problem?
Shopify is not designed for legal French and European invoicing.

Don't panic.
We're going to see what you absolutely must comply with, without jargon, without indigestible legal articles, and with concrete examples.

Shopify Invoicing: What the Law Really Expects (France / EU)

First thing to clarify:
an invoice is not just an order summary.

To be compliant in France and the European Union, an invoice must contain certain mandatory information.

In practice, you need at least:

• seller's identity (company name, address),
• SIREN / SIRET number,
• unique and chronological invoice number,
• date of issue,
• customer's identity (at least name + address),
• product/service details,
• amount ex-VAT, VAT, incl-VAT (or exemption mention),
• applicable VAT rate.

👉 Without this, your document is not considered a real invoice.

Critical Point #1: Invoice Numbering

This is the most common mistake.

In real life, I often see:

• invoices renamed manually,
• PDFs exported without logic,
• or numbers that reset to zero every month ❌

What the law expects:

• a continuous, chronological, and unique numbering,
• without gaps,
• without duplicates.

👉 Shopify does not handle this natively.

Without a dedicated tool, you have to do it manually… and that's where errors happen.

VAT: Where It Gets Complicated (France + EU)

Another sensitive point: VAT.

Depending on your situation, you may be:

• VAT exempt,
• subject to French VAT,
• making intra-community sales,
• or making sales outside the EU.

In practice, this means:

• displaying (or not displaying) VAT,
• using the correct rates,
• adding the correct legal mention ("VAT not applicable, art. 293B", reverse charge, etc.).

👉 Shopify calculates taxes…
but does not secure the final invoice.

This is often where errors creep in.

Customer Invoices: Should They Be Sent Automatically?

Another frequent question:

"Do I have to send an invoice to every customer?"

In practice:

• for business customers, yes, without hesitation,

• for private individuals, the invoice must be available upon request or automatically.

What is important:

• that the invoice exists,

• that it is archived,

• and that it can be provided quickly.

👉 Here again, Shopify alone is not enough.

The Simplest Solution for Staying Compliant

To avoid:

• oversights,

• VAT errors,

• manual, cobbled-together invoices,

the most logical solution remains:
👉 a Shopify-compatible invoicing application.

For example, Regulo allows for:

• automatic generation of compliant invoices,

• legal numbering,

• automatic addition of mandatory information,

• VAT management for France / EU.

It's not an absolute obligation,
but in real life, it's what prevents 90% of problems.

Conclusion

To summarize simply:

✔️ Shopify is not enough for legal invoicing
✔️ France / EU rules are precise (but manageable)
✔️ Compliance relies mainly on:

• numbering,
• mentions,
• VAT

👉 With the right tool, invoicing becomes automatic and much less stressful.

The goal is not to be perfect,
but to be calm and compliant, without spending your evenings on it.
