This is a courtesy translation. The French version is the legally binding text.
These Terms and Conditions of Sale and Service (hereafter "the Terms") set out the terms on which Nova Studio, a collective of freelancers made up of Yann Mostowski and Mathieu Dubust (hereafter "the Provider"), supplies its services to the client (hereafter "the Client").
The services offered include: custom web development, SaaS creation, artificial intelligence integration, modernisation of business tools and product design (UI/UX).
These Terms apply to all service engagements between the Provider and the Client. Placing an order implies unreserved acceptance of these Terms.
Any specific conditions negotiated between the parties prevail over these Terms in the event of contradiction.
Every engagement is preceded by a detailed quote, free of charge and without obligation. The quote sets out the nature of the services, the expected timeline, the price and the payment terms.
The quote is valid for 30 days from its issue date. The order is considered firm and final once the Client has accepted the quote in writing (signature, confirmation email) and paid the agreed deposit.
Prices are given in euros (EUR) excluding tax. As sole traders, the services are exempt from VAT under article 293 B of the French General Tax Code (VAT not applicable).
Unless stated otherwise in the quote, payment terms are as follows:
Payment is made by bank transfer within 30 days of the invoice date. Late payment automatically incurs late penalties at three times the statutory interest rate, plus a fixed recovery fee of 40 euros.
The Provider undertakes to carry out the work diligently and professionally, in line with industry standards. The services are provided under a best-efforts obligation.
A typical project runs through the following stages:
The Client undertakes to provide the Provider with all information, content and access needed to carry out the work within the agreed timeframe.
Delivery timelines are indicative and depend in particular on the complexity of the project and on how quickly the Client provides approvals and feedback. The Provider strives to meet agreed timelines and informs the Client of any delay.
Delays attributable to the Client (late delivery of content, late approvals, scope changes) cannot engage the Provider's liability.
At each key stage and on final delivery, the Client has 7 working days to approve the deliverables or raise reservations in writing. After that period, deliverables are deemed accepted.
Changes requested after a stage has been approved may be subject to an additional quote.
Intellectual property rights in the deliverables transfer once the agreed price has been paid in full. Until full payment, the Provider retains all rights over the work produced.
The Provider reserves the right to mention the project in its commercial references and portfolio, unless the Client objects in writing.
Materials supplied by the Client (text, images, logos) remain its property. The Client warrants that it holds the necessary rights over those materials and releases the Provider from any liability in that respect.
Each party undertakes to keep confidential the information and documents exchanged during the engagement. This obligation remains in force for the duration of the commercial relationship and for 2 years afterwards.
The Provider undertakes to perform its services with care and diligence. Its liability is limited to the amounts actually paid by the Client for the engagement concerned.
The Provider cannot be held liable for indirect damages such as loss of revenue, loss of data, commercial loss or reputational harm.
The Provider cannot be held liable in the event of force majeure or events beyond its control.
Should either party fail to meet its obligations, the other party may terminate the contract after a formal notice has remained without effect for 15 days.
If the Client terminates early, sums already paid remain acquired by the Provider. Work carried out up to the termination date will be invoiced pro rata.
The Provider warrants the correction of defects and bugs arising from its development work for 30 days following final delivery. This warranty covers only malfunctions attributable to the Provider.
Any maintenance, evolution or support beyond that warranty period is subject to a separate contract.
The Provider undertakes to comply with applicable personal data protection regulations, in particular the GDPR. For more information, see our Privacy Policy.
Under articles L.616-1 and R.616-1 of the French Consumer Code, in the event of a dispute, a consumer Client may use a consumer mediation service free of charge. The mediator will independently seek to bring the parties together towards an amicable resolution.
These Terms are governed by French law. In the event of a dispute, and after attempting an amicable resolution, the courts of Paris shall have sole jurisdiction.
