Only1Agency is hereinafter referred to as "the Agency." Any person or company ordering a service is referred to as "the Client."
2. Purpose and scope of application
These GTC govern all contractual relationships between the Agency and the Client, particularly for digital marketing services, social media management, content creation, photography, video, online advertising, SEO, website creation, digital strategy, consulting, and support.
Any order, signing of a quote, written validation, payment of a deposit, or commencement of service execution constitutes unconditional acceptance of these GTC.
The specific conditions stated in a quote, purchase order, contract, or invoice accepted by the Client take precedence over these GTC in case of contradiction.
3. Quotes and conclusion of the contract
The quotes issued by the Agency are valid for a period of 30 days, unless otherwise stated.
A quote becomes contractual as soon as it is accepted in writing, signed, validated electronically, or accompanied by the payment of the required deposit.
The included services, their price, their estimated schedule, payment terms, the number of possible revisions, and the deliverables are specified in the quote or in any contractual document accepted by the Client.
Any request not included in the initial scope will be subject to an additional quote or additional billing.
4. Price and billing
Prices are expressed in euros and excluding taxes, unless otherwise stated. The applicable VAT is added in accordance with current regulations.
Services are billed according to the conditions indicated in the quote, the contract, or the invoice. In the absence of specific conditions, invoices are payable within 15 days from their date of issue.
External costs necessary for the service, including advertising budgets, licenses, subscriptions, domain names, hosting, travel expenses, media purchases, third-party tools, or subcontractor services, are not included unless expressly stated.
For consumers, applicable prices are communicated clearly, legibly, and all taxes included before the conclusion of the contract, in accordance with Luxembourg rules regarding price information.Guichet.lu
5. Deposit and default of payment
When the quote provides for a deposit, the Agency may defer the start of the service until its actual collection.
In case of late payment, the Agency reserves the right to:
- immediately suspend ongoing services;
- suspend access to the deliverables, accounts, content, or relevant sites;
- apply late fees and legally applicable penalties;
- request reimbursement of reasonable expenses incurred for collection;
- terminate the contract after a formal notice that remains unaddressed.
Late payment does not release the Client from their contractual obligations.
6. Client Obligations
The Client agrees to:
- provide accurate, complete, and up-to-date information;
- transmit in a timely manner the necessary elements for the performance of the service;
- designate a contact person authorized to validate the deliverables;
- verify the content, visuals, texts, links, legal mentions, and information before publication;
- hold the necessary rights to the content, images, brands, logos, databases, and documents they transmit;
- comply with the laws, regulations, and policies of the platforms used.
The Client remains solely responsible for the legality, accuracy, and rights attached to the elements they provide to the Agency.
Any delay, lack of validation, or failure to transmit elements by the Client may result in a shift in the schedule, without the Agency's liability being engaged.
7. Deadlines and execution of services
The deadlines communicated by the Agency are indicative, unless otherwise stated in writing. They depend in particular on the availability of information, validations, technical access, and content provided by the Client.
The Agency commits to implementing the reasonable means necessary for the proper execution of its services. The obligations of the Agency are obligations of means and not of results.
Delays caused by the Client, a third party, an external platform, a host, an advertiser, a public authority, or a force majeure event cannot give rise to compensation.
8. Validation and revisions
The Client must submit their correction requests or validations within the timeframes indicated by the Agency. In the absence of feedback within a reasonable time, the Agency may consider the relevant stage as validated in order to preserve the project schedule.
The number of included revisions is that specified in the quote. Any request for additional modifications, changes in direction, addition of functionality, or new requests after validation may be charged extra.
9. Marketing and advertising services
The Agency does not guarantee any minimum level of sales, revenue, leads, audience, search engine ranking, visibility, conversion, or return on investment.
The results of marketing campaigns and actions depend in particular on the market, budget, offer, competition, quality of content, responsiveness of the Client, user behavior, and platform rules.
The Client is responsible for advertising accounts, payment methods, media budgets, and necessary authorizations. The Agency can manage the Client's accounts without becoming the owner of the accounts, audiences, pixels, or data that belong to them.
Google, Meta, TikTok, LinkedIn, and any other platform can change their policies, algorithms, pricing, broadcasting rules, or suspend an account. The Agency cannot be held responsible for these decisions.
10. Creation of websites and technical services
For web projects, the Client agrees to provide in a timely manner the texts, visuals, access, legal notices, privacy policy, logos, and necessary content.
Unless otherwise stated, the Agency does not guarantee the permanent compatibility of a site with future developments of browsers, operating systems, extensions, third-party tools, or external platforms.
Hosting, domain name, email, online payment, booking, mapping, or third-party integration services are subject to the terms of their providers. The Agency cannot be held responsible for their unavailability, changes, or interruptions.
11. Intellectual property
The Agency retains ownership of its methods, tools, templates, mockups, generic graphic elements, reusable codes, processes, know-how, and pre-existing rights.
After full payment of all amounts due, the Client benefits from usage rights on the deliverables created specifically for them, within the limits specified in the quote or contract.
Unless there is an express written assignment, the delivery of a deliverable does not constitute a full transfer of intellectual property rights. Source files, source codes, working files, third-party licenses, and elements not included in the quote are not automatically included.
The Agency may present the achievements made for the Client in its portfolio, on its website, its social media, or its commercial materials, unless there is a written and justified opposition from the Client.
12. Confidentiality
Each party agrees to maintain the confidentiality of the information, documents, strategies, access, business or technical data received in the context of the contractual relationship.
This obligation does not apply to information that is already public, legally obtained from a third party, or whose disclosure is required by law or a competent authority.
13. Protection of personal data
Personal data is processed in accordance with Only1Agency's privacy policy and applicable regulations, including the General Data Protection Regulation.
When the Agency processes personal data on behalf of the Client as part of a service, the parties may enter into a subcontracting agreement specifying their respective obligations.
14. Liability
The Agency can only be held liable for direct, certain, and foreseeable damages resulting from a fault attributable to it.
To the extent permitted by law, the Agency shall not be liable for indirect losses, loss of revenue, loss of data, loss of opportunity, damage to reputation, loss of profits, consequences of improper use of deliverables, or malfunctions attributable to third-party providers.
In any case, the total liability of the Agency is limited to the amount actually paid by the Client for the service that directly caused the damage.
No clause in these terms and conditions limits the mandatory rights of a consumer.
15. Suspension, termination, and cancellation
Each party may terminate a recurring service according to the terms specified in the quote or contract.
In the event of termination by the Client after the start of a service, the work already completed, the time spent, commitments made to third parties, and incurred costs remain due.
In the case of a serious breach by the Client, including failure to pay, prolonged absence of collaboration, provision of illegal content, or harmful behavior, the Agency may suspend or terminate the service after written notification.
When the Client is a consumer and a right of withdrawal applies, the legal information regarding this right is communicated to them before the conclusion of the contract. The applicable conditions and exceptions depend in particular on the type of service and the commencement of its execution. Guichet.lu
16. Force majeure
No party shall be held liable for a breach resulting from an event reasonably beyond its control, including a widespread failure, cyberattack, natural disaster, strike, war, pandemic, failure of an essential supplier, administrative decision, or interruption of a third-party service.
17. Complaints and applicable law
Any complaint must be addressed in writing to info@only1agency.lu , with the information necessary for its examination.
These terms and conditions are governed by Luxembourg law.
In case of dispute, the parties strive to find an amicable solution. Failing that, the competent jurisdictions of Luxembourg will be seized, subject to the mandatory rules applicable to consumers.
