A professional quote is legally binding as soon as it is signed by the client. The validity of this document relies on specific mandatory mentions, the absence of which exposes one to penalties. Between the common rules applicable to all activities and the sector-specific requirements (construction, self-employed, VAT exemption), the discrepancies are numerous and often misunderstood.
Quote mentions according to status: comparative table of obligations
The mentions to be included in a quote vary depending on the legal status of the company and the sector of activity. The table below summarizes the main differences.

| Mention | Company (SARL, SAS, etc.) | Self-employed | Construction Artisan |
|---|---|---|---|
| Word “Quote” | Yes | Yes | Yes |
| Company name / Name | Company name + legal form | First and last name | Company name or name |
| SIREN number | Yes | Yes | Yes |
| Head office address | Yes | Yes | Yes |
| VAT (rate + amount) | Yes (except for VAT exemption) | Mention “VAT not applicable, art. 293 B of the CGI” if exempt | Yes |
| Professional insurance | Not mandatory (except for construction) | Not mandatory (except for construction) | Name of the insurer, contact details, geographical coverage area |
| Mention “quote received before work execution” | No | No | Yes |
| Client’s signature | Recommended | Recommended | Mandatory above a certain amount |
This table highlights a point that many general guides overlook: the obligations for construction far exceed the common baseline. Professional insurance, for example, must not only mention the nature of the coverage but also the precise contact details of the insurer and the geographical area covered.
To delve deeper into mandatory mentions on a quote, each status deserves careful reading of the applicable texts for its sector.

Quote obligation threshold: what the 2017 decree changed
The decree of January 24, 2017, modified the rules for building work and repairs. Before this text, a threshold of 150 euros including tax often exempted the professional from providing a written quote. This threshold has been removed for many building services, making the quote mandatory regardless of the amount.
The activities concerned cover a wide spectrum:
- Masonry, plumbing, electricity, roofing, insulation, locksmithing, painting, glazing
- Chimney sweeping, flue gas, climate engineering (including renewable energies)
- Pest control, insect control, maintenance of alarm and remote surveillance systems
- Maintenance of fire extinguishers, cleaning of wastewater, unblocking of pipes
On the other hand, other sectors remain subject to different thresholds or solely at the client’s request. Moving services or certain personal services, for example, do not have the same regulatory constraints.
This removal of the threshold means that an artisan called for a simple locksmith repair must provide a detailed quote before any intervention. Failing to do so exposes one to an administrative fine.
VAT and exemption: the mention that traps self-employed individuals
The management of VAT on a quote generates frequent errors. A taxable professional must display the applicable VAT rate, the amount of VAT, and the total including tax for each line of service.
For self-employed individuals or companies benefiting from VAT exemption, the rule is different. The mention “VAT not applicable, art. 293 B of the CGI” must appear on the quote. Omitting this mention or, conversely, charging VAT when one is not liable constitutes an infringement.
The most common error is presenting an amount excluding tax and an amount including tax that are identical without any explanation. The client does not understand why there is no VAT, and the document loses its transparency value. The legal mention removes this ambiguity.
Contractual mentions beyond the legal minimum
The regulatory framework covers the identification of the parties, the details of the services, the price, the validity period, and the payment conditions. However, a quote that limits itself to these elements leaves gray areas in case of dispute.
Clauses that secure the professional and the client
Several optional mentions enhance the contractual value of the quote:
- General terms and conditions of sale (GTCS), which frame the respective responsibilities
- Late payment penalties, with the applicable rate and calculation methods
- A detailed payment schedule, especially for long projects with a deposit
- Execution conditions (deadlines, access to the site, provision of materials by the client)
A signed quote without attached GTCS offers little recourse in case of disagreement over the execution terms. Including these elements right from the quote avoids having to negotiate them afterward.
Validity period of the quote: a common trap
The validity period of the offer is a mandatory mention often rushed. A quote without a deadline for acceptance remains theoretically valid for a reasonable period, but this vague notion turns against the professional if material prices increase in the meantime.
Setting an explicit validity period (one month, three months) protects against late acceptances at an outdated rate. The validity period commits the professional to the price for the entire indicated period.
Sanctions in case of non-compliant quote
The absence of mandatory mentions on a quote exposes the professional to an administrative fine. The amount varies depending on the severity of the omission and the status of the company: individual or legal entity.
Beyond the fine, an incomplete quote weakens the professional’s position in case of commercial dispute. A client can contest the billed amount if the quote did not sufficiently detail the services, quantities, or unit price.
The most underestimated risk remains the reclassification of the quote. A document that does not carry the mention “quote” or omits regulatory information may not be recognized as a valid contractual commitment by a court. The professional then loses their proof of order.
The compliance of a quote is not limited to ticking off a list of mentions. It conditions the legal solidity of the commercial relationship, the ability to collect a deposit, and the credibility in front of a client comparing several offers.
