Terms of sale

These terms apply to the OPUS Heritage services provided by OPUS France to local authorities, foundations and monument owners (business customers and public entities). They do not apply to visitors of the site, whose use is governed by the terms of use. This translation is provided for convenience; the French version prevails.

1. Purpose

These terms of sale govern the OPUS Heritage services: provision of the platform (monument pages, virtual tours, trails, administration console), production and integration of content, supply and installation of signage (QR plaques), support and consulting. They apply unless specific terms are agreed in writing — quotation, contract or public procurement documents — which prevail. They are provided on request (Article L441-1 of the French Commercial Code).

2. Ordering

An order takes effect upon signature of a quotation or purchase order, or in the forms provided by the public procurement rules applicable to the customer. The quotation specifies the scope, schedule and price of the services.

3. Prices

Prices are expressed in euros excluding taxes; VAT is added at the applicable rate. Services are invoiced at the price stated in the quotation. Manufacturing and installation of signage are invoiced as quoted.

4. Payment

Invoices are payable within 30 days. Public entities pay by administrative mandate within the regulatory deadlines. Any late payment automatically incurs penalties at the European Central Bank rate plus 10 points and, for business customers, the €40 fixed recovery indemnity (Article L441-10 of the French Commercial Code); for public entities, the regulatory late-payment interest applies.

5. Term

Access to the platform is provided for the term stated in the quotation and renews under the conditions it specifies. One-off services (content, signage, support) are deemed performed upon delivery or completion.

6. Obligations of OPUS France

OPUS France hosts the platform, maintains it, performs regular backups and provides support to the customer. It is bound by a best-efforts obligation; scheduled maintenance likely to interrupt the service is announced in advance.

7. Obligations of the customer

The customer provides the content (texts, images, documents) within the agreed deadlines and warrants that it holds the rights required for its publication. It appoints a contact person for the project and remains editorially responsible for the information published under its name.

8. Intellectual property

The platform and its developments remain the property of OPUS France, which grants the customer a right of use for the term of the contract. Content provided by the customer remains its property. The status of content produced by OPUS France for the customer (assignment or licence) is specified in the quotation.

9. Personal data

For the data of visitors of the platform, the customer and OPUS France act as joint controllers (Article 26 GDPR), as described in the privacy policy. For processing carried out on the customer’s behalf, OPUS France acts as a processor (Article 28). Data is hosted within the European Union.

10. Reversibility

At the end of the contract, OPUS France returns to the customer its content and the associated data in a standard, reusable format.

11. Liability

OPUS France’s liability is limited to direct damages and capped at the amounts paid by the customer over the last twelve months. Indirect damages (loss of business, image or data not attributable to OPUS France) are excluded. Nothing excludes liability for gross negligence or wilful misconduct.

12. Termination

In the event of a serious breach not remedied within 30 days of formal notice, the contract may be terminated by the injured party. Services already performed remain payable.

13. Force majeure

Neither party is liable for a failure caused by a force majeure event within the meaning of Article 1218 of the French Civil Code. If the impediment lasts more than 60 days, either party may terminate without compensation.

14. Governing law and jurisdiction

These terms of sale are governed by French law. Disputes with private customers fall under the jurisdiction of the courts of the registered office of OPUS France; disputes arising from public contracts are brought before the competent administrative court. For any question: contact@opusheritage.com. The French version prevails over this translation.
