General Terms and Conditions of Sale
Last updated: January 3rd, 2026
These General Terms and Conditions of Sale (hereinafter "Terms") govern all consulting services provided by Hyperion Consulting to business clients. By engaging our services, you accept these Terms in their entirety.
These Terms apply exclusively to B2B relationships between Hyperion Consulting and professional clients. Consumer protection regulations do not apply. These Terms prevail over any conflicting terms in the Client's purchase orders or other documents unless explicitly agreed otherwise in writing.
In accordance with Article L221-3 of the French Consumer Code, the right of withdrawal provided under Articles L221-18 et seq. does not apply to contracts concluded between professionals. As our services are provided exclusively to business clients (B2B), no consumer withdrawal period applies.
In accordance with Articles 1366 and 1367 of the French Civil Code and Articles 25 et seq. of the LCEN (Law for Confidence in the Digital Economy, No. 2004-575), electronic signatures and electronic acceptances (including email confirmations) have the same legal validity as handwritten signatures. Accepted proposals and signed contracts are archived electronically for a minimum period of 10 years and are made available upon request.

Each engagement is tailored to the Client's specific needs. The exact scope, deliverables, and approach are defined in individual Proposals.
Unless otherwise stated, Proposals are valid for 30 days from the date of issue. After this period, Hyperion Consulting reserves the right to revise the terms.
Engagements are formed upon written acceptance of a Proposal by the Client. Acceptance may be via signed proposal, email confirmation, or purchase order referencing the Proposal.
Any changes to the agreed scope require written agreement from both parties. Additional work outside the original scope will be quoted separately.
All pricing is provided in individual Proposals based on the specific scope and complexity of each engagement. Pricing may be structured as fixed-fee, time-and-materials, or retainer arrangements as appropriate for the engagement.
All prices are quoted exclusive of applicable taxes. VAT will be applied in accordance with French and EU regulations. For intra-EU B2B transactions, reverse charge may apply subject to valid VAT identification.
Invoices are issued according to the payment schedule defined in the Proposal. Typical arrangements include advance payment for initial phases, milestone-based payments, or monthly billing for retainer engagements.
Unless otherwise specified in the Proposal, payment is due within 30 days of invoice date. Payment shall be made by bank transfer to the account specified on the invoice.
Services are delivered using our proprietary DEPLOY Method™ framework, adapted to each Client's context. Our approach combines strategic analysis, hands-on implementation, and knowledge transfer to ensure lasting impact.
Services may be delivered remotely, on-site at Client premises, or in a hybrid format as agreed in the Proposal. Travel expenses for on-site work are invoiced separately unless included in the fixed fee.
Successful delivery requires active Client participation. The Client agrees to provide timely access to relevant personnel, systems, data, and facilities as reasonably required. Delays caused by lack of Client cooperation may result in timeline extensions and additional costs.
Indicative timelines are provided in Proposals. Actual delivery depends on engagement complexity and Client responsiveness. Hyperion Consulting will communicate proactively about any timeline adjustments.
Deliverables are provided in professional formats appropriate to their nature: strategic documents in PDF/presentation format, technical specifications in appropriate formats, and training materials in presentation or video format.
Upon delivery, the Client has 10 business days to review deliverables and provide feedback. Reasonable revisions within the original scope are included. After the review period, deliverables are deemed accepted.
Deliverables are considered accepted when they substantially conform to the specifications in the Proposal. Minor deviations that do not materially affect the utility of the deliverable do not constitute grounds for rejection.
Each party retains ownership of its pre-existing intellectual property. Hyperion Consulting's methodologies, frameworks (including DEPLOY Method™), tools, and know-how remain the exclusive property of Hyperion Consulting.
Upon full payment, the Client receives a perpetual, non-exclusive license to use deliverables created specifically for their engagement for their internal business purposes. This license does not include the right to sublicense or commercialize the deliverables.
Both parties agree to maintain strict confidentiality of all non-public information shared during the engagement. This includes business strategies, technical specifications, financial information, and any other sensitive data.
Confidentiality obligations survive the termination of the engagement and continue for a period of 5 years, unless the information becomes publicly available through no fault of the receiving party.
Consulting services are advisory in nature. While Hyperion Consulting strives to provide valuable insights and recommendations, the ultimate decision-making and implementation responsibility rests with the Client. No guarantee of specific business outcomes is implied.
Hyperion Consulting's total liability for any claims arising from an engagement shall not exceed the total fees paid by the Client for that specific engagement.
Neither party shall be liable for indirect, incidental, consequential, or punitive damages, including but not limited to loss of profits, data, or business opportunities, regardless of the cause of action.
The above limitations do not apply to: (a) breaches of confidentiality obligations; (b) infringement of intellectual property rights; (c) gross negligence or willful misconduct; or (d) liability that cannot be limited by law.
Either party may terminate an engagement with 30 days' written notice. Upon termination, the Client shall pay for all services rendered and expenses incurred up to the termination date.
Neither party shall be liable for delays or failures in performance due to circumstances beyond their reasonable control, including but not limited to natural disasters, war, terrorism, labor disputes, government actions, pandemic, or infrastructure failures.
The affected party must promptly notify the other party and use reasonable efforts to mitigate the impact. If the force majeure event continues for more than 60 days, either party may terminate the affected engagement without penalty.
These Terms, together with the applicable Proposal, constitute the entire agreement between the parties and supersede all prior discussions, negotiations, and agreements.
These Terms may only be amended by written agreement signed by authorized representatives of both parties. Hyperion Consulting may update these Terms from time to time; the version in effect at engagement commencement applies to that engagement.
If any provision of these Terms is found to be unenforceable, the remaining provisions shall continue in full force and effect.
Neither party may assign its rights or obligations without the other's written consent, except that Hyperion Consulting may assign to an affiliate or successor in the event of a merger or acquisition.
Failure to enforce any provision of these Terms shall not constitute a waiver of that provision or any other provision.
Hyperion Consulting maintains professional liability insurance (Responsabilité Civile Professionnelle) covering its consulting activities.
Certificate of insurance is available upon request.
These Terms and all engagements are governed by the laws of France, without regard to conflict of laws principles.
Any disputes arising from these Terms or related engagements shall be subject to the exclusive jurisdiction of the Commercial Court of Nanterre, France.
Before initiating formal proceedings, the parties agree to attempt resolution through good-faith negotiation for a minimum period of 30 days. If negotiation fails, the parties agree to submit the dispute to mediation before the Centre de Médiation et d'Arbitrage de Paris (CMAP) before proceeding to litigation.
If mediation fails or if either party refuses mediation, disputes shall be submitted to the Commercial Court of Nanterre, France.
