France's e-invoicing rules: What self-storage operators need to know
contents
Introduction
This is a fast-moving area of regulation. This article reflects our understanding of the rules as of August 2026, based on the French government’s official guidance. We will update it as the rules develop. If you are unsure which size bracket your business falls into, your accountant will be able to confirm this.
A lot of French operators have been asking the same question: are we compliant with the new e-invoicing rules? The reform actually sets out two separate obligations, and they land at different times depending on the size of your business.
Two dates, two obligations
Receiving e-invoices: every VAT-registered business in France, regardless of size, must be able to receive electronic invoices from 1 September 2026.
Issuing e-invoices: large and mid-sized companies (ETI) must issue electronic invoices from 1 September 2026. Small and medium businesses, including micro-entrepreneurs, have an extra year: their obligation to issue starts on 1 September 2027.
Business size, not sector or turnover alone, determines which issuing date applies.
Where most self-storage operators sit
Outside a small number of large groups (the exceptions being Shurgard and Homebox, both listed businesses), most self-storage operators in France are small or medium businesses. That means the obligation to issue electronic invoices does not apply until September 2027, a full year after the date most commonly discussed.
The obligation that starts in September 2026, for most operators, is the receiving one.
What "receiving" means in practice
From September 2026, invoices from large suppliers (electricity, telecoms, insurance) will start arriving in a structured format (Factur-X, UBL or CII) through an approved platform, known as a Plateforme Agréée.
Being able to receive an e-invoice is not a feature that storage management software switches on automatically. It is a registration a business has to complete: designating a Plateforme Agréée to receive invoices on its behalf, in the same way a business would register a VAT number. Software can connect to that registration, but it does not substitute for it. The registration itself sits with the business.
What "issuing" will mean, from 2027
For invoices sent from a French business to another French business, the accepted formats are Factur-X (a hybrid PDF with embedded data, similar in principle to Germany’s ZUGFeRD), UBL 2.1, or CII, all aligned with the EN 16931 European standard. A plain PDF will no longer be accepted for these invoices after the relevant date.
Separately, the reform also introduces “e-reporting” requirements: daily aggregated reporting for B2C transactions, and transaction reporting for cross-border B2B invoices. This runs alongside e-invoicing rather than replacing it.
The pace of the reform
This mandate has already been delayed more than once, and the dates above are the ones currently written into law. France has also abandoned its original plan for a free public invoicing portal (the PPF); all businesses will use a certified private Plateforme Agréée instead.
