The problem

Forming a company: the qualified signature can block creation

Most company formations don't require a qualified signature, BUT some do: in-kind contributions, statutes with shareholder advances, FranceConnect+ that fails. In all these cases, the INPI requires the eIDAS qualified level.

In-kind contributions = qualified signature

If your company involves in-kind contributions (real estate, vehicle, brand), the INPI requires the qualified level on the summary.

FranceConnect+ unstable

Even for "simple" formations, when FranceConnect+ fails, the qualified signature via an alternative provider unblocks the file.

Activity start delayed

Each day of delay = each day without SIRET, without bank account, without billing. The signature must be applied without waiting.

Frequently asked questions

Company formation: everything you need to know

When does an INPI company formation require a qualified signature?+
3 main cases: in-kind contributions (real estate, vehicle, brand, etc.), complex bylaws (clauses requiring authentic act), or FranceConnect+ failure on the standard flow. The Guichet Unique then proposes the option to upload an externally signed PDF.
For a micro-enterprise, do I need a qualified signature?+

Yes, in this case the qualified signature is required on the formation summary. Our service covers this scenario.

2 to 5 minutes: upload, form, payment, identity verification, qualified signature. Signed summary delivered by email immediately.
How much does it cost?+
The price is displayed at payment. One-time fee, no subscription. Official INPI/CFE fees are paid separately to the INPI.
