Business creation filing receipt: what value, what duration

Quick answer. The filing receipt issued by the INPI single window confirms that a creation file has been submitted and is pending registration, a process centralised since 1 January 2023. It is not a registration, grants no legal personality and remains valid until the final decision. The SIREN number is usually assigned in about two weeks, this time frame being indicative and not guaranteed.

You validated your file on the single window and received a document marked "pending registration". The same question arises in nearly every creation case we handle: is this receipt enough to sign a lease, open an account or invoice a first client? Answering it means separating what the document actually proves from what your counterparties will really require.

Since 1 January 2023, all business creation, modification and termination formalities go through the INPI single window for business formalities, at formalites.entreprises.gouv.fr. This portal replaced the former business formality centres (CFE).

When you submit a complete file with its supporting documents, you receive a filing receipt stating that the formality is "pending registration". The document attests one thing only: a file has been submitted and is under review.

The receipt is not a registration. For a company, legal personality only arises from registration with the trade and companies register (RCS). Until that registration is granted, the company in formation has no separate legal existence.

The receipt is not useless. It lets you start certain preliminary steps before the Kbis extract or the SIRET is issued, while registration is being finalised.

In practice, it serves mainly to take out the mandatory professional insurance for your activity and to complete certain formalities with bodies that accept a file in progress. It is proof of a step taken, not proof of a registered business.

See our business creation support to sequence these steps in the right order and avoid bottlenecks.

The receipt has no fixed duration in days. It remains valid until the single window confirms that registration is effective, or, conversely, until the file is rejected. It therefore lasts until the final decision, not for a set number of days.

The process runs in several steps:

1. You submit the creation formality on the single window with all documents.
2. INSEE pre-assigns a SIREN number to the business.
3. The file is sent to the competent authority: the commercial court registry, the chamber of trades or URSSAF, depending on the activity and legal form.
4. Once approved on the merits, the business is registered and the SIREN becomes final.
5. The Kbis, the RCS registration extract, is issued for companies and traders.

The indicative time to obtain the SIREN for a creation is about two weeks. For a complete file, the registry usually processes the request in seven to nine business days. These times are indicative, not guaranteed: they depend on the activity and any blockages at the single window.

The filing receipt reassures the founder, but it rarely reassures their partners. In creation files, the most common misunderstanding is to believe that this document grants all the rights of a registered business. It attests a filing in progress, nothing more.

Our reading is simple: treat the receipt as an amber light. You can prepare the ground (insurance, non-binding quotes, choice of bank), but reserve firm commitments and invoicing for the moment the SIREN is confirmed. This sequence protects both your cash position and your commercial relationships.

The least anticipated risk lies in the provisional nature of the SIREN number pre-assigned by INSEE. This number is only final once the competent authority has validated the file. While the file is under review, a rejection or a blockage remains possible.

Blockages at the single window have been frequent since 2023. A file rejected for a missing document, a poorly drafted corporate purpose or an unjustified regulated activity does not lead to registration, even if you hold a receipt. If your activity requires authorisation, plan ahead with our pointers to check whether your activity is regulated.

We also see founders issue an invoice on the strength of the receipt, before the SIREN is final. A company in the process of registration may, if needed, invoice while stating "SIRET pending assignment", provided the articles of association are signed and the formalities under way, then correct it with a rectifying invoice once the SIRET is assigned. We nevertheless recommend waiting for the final SIREN: invoicing too early exposes you to a payment refusal by the client and complicates VAT deduction on their side.

A partner, a bank or a client who requires a Kbis is under no obligation to accept the receipt. The Kbis is the official RCS registration extract, issued after registration is effective. It proves legal existence; the receipt only proves the filing.

This hierarchy explains why we advise waiting for the final SIREN before any structural commitment: it is what your counterparties look at, and what underpins our corporate tax support.

The period between filing and registration should be managed actively. Here is the checklist we apply in our creation files:

• Keep the filing receipt and its acknowledgement: it evidences the start date of the formality.
• Monitor the file status in your single window account and respond quickly to any request for additional documents.
• Anticipate opening a professional bank account by preparing the supporting documents, without paying in the final capital before registration for a company.
• Check the correct share capital amount in advance, as an inconsistent capital can slow the review.
• Prepare, but do not file prematurely, the beneficial owners declaration, which is part of the single window process.
• Defer first invoicing and firm contracts until the final SIREN is assigned.

For a sole trader or micro-entrepreneur, there is no Kbis: the SIREN identifier and the Sirene register status notice from INSEE serve as proof of existence once registration is done. Here too, the filing receipt is merely proof of a file in progress.

For a company (SAS, SARL, SCI), legal personality arises from RCS registration. Acts entered into on behalf of the company in formation, on the sole basis of the receipt, must be taken over by the company once registered in order to bind it validly.

Recently, a director consulted us after signing a supplier order on the strength of his receipt, convinced his company already existed. The file had been suspended at the single window over a partly regulated activity. The result: a commitment made in the name of a company not yet registered, and an anxious supplier.

We regularised the situation by clarifying the company-in-formation status, completing the file and having the commitment taken over by the company once registered. This case illustrates our conviction: the receipt is an administrative starting point, not an authorisation to act as a registered business.

As a firm registered with the French Order of Chartered Accountants, we structure this phase so that creation turns into registration without premature commitments, and we move on to the accounts presentation engagement as soon as the first transactions occur.

Hayot Expertise tip. Treat the receipt as proof of a step, not of a business. Prepare insurance and your bank account, but wait for the final SIREN before invoicing, signing a lease or committing the company. If the single window requests a document, respond within a few days to avoid a blockage. Have the sequencing secured by your chartered accountant.
