Terms of Sale
Last updated: March 23, 2026
1. Purpose and scope
These Terms of Sale govern all commercial relationships between YdvSystems, a sole proprietorship operated by Yohann Dandeville (French business registration SIRET 534 080 783 00028), hereinafter referred to as "the Provider", and any individual or legal entity subscribing to its services, hereinafter referred to as "the Client".
Any order or subscription implies unreserved acceptance of these Terms of Sale. They apply to SaaS solutions offered on ydvsystems.com as well as to freelance development services.
2. SaaS solutions
YdvSystems offers four SaaS solutions: YDV Insertion (management for work integration organizations), YDV Formation (training organization management with Qualiopi compliance), YDV Bilan (skills assessment management) and YDV Manager (business management and invoicing for freelancers and small businesses).
Each solution is accessible via a web browser after creating an account. A 30-day free trial is offered. A bank imprint of €1 is requested to verify the Client's identity; this amount is cancelled immediately and will never be charged. The trial provides full access to all features of the chosen solution.
At the end of the trial period, the account is suspended if the Client has not subscribed. No automatic charges are made. The Client may subscribe to a monthly or annual plan at any time. The subscription takes effect on the subscription date and renews automatically at each billing cycle, unless cancelled under the conditions set out in Section 6.
3. Freelance services
Custom development, AI integration and consulting services are subject to a prior quotation detailing the scope, deliverables, timeline and amount. Quotations are valid for 30 days from the date of issue.
Unless otherwise agreed, a deposit of 30% of the total amount is required upon signing the quotation. The balance is invoiced upon delivery of the deliverables defined in the quotation. For long-term projects, an intermediate payment schedule may be agreed upon.
4. Pricing and payment
Prices are quoted in euros, exclusive of tax (HT). In accordance with French micro-enterprise regulations, YdvSystems is not subject to VAT (Article 293 B of the French General Tax Code). The statement "VAT not applicable, Article 293 B of the CGI" appears on every invoice.
Payment is made by credit card or bank transfer. SaaS subscriptions are billed on a recurring basis according to the chosen frequency (monthly, quarterly or annual). Invoices are sent electronically to the Client's email address.
5. Free trial
The 30-day free trial provides access to all features of the chosen solution without any limitations. A bank imprint of €1 is requested to verify the Client's identity. This amount is cancelled immediately and will never be charged. Upon expiration of the trial period, the account is suspended. No automatic charges are made. The Client's data is retained for an additional 30 days, allowing time to subscribe or export data.
6. Duration and cancellation
The subscription is taken out for the duration chosen by the Client (monthly, quarterly or annual). The Client may cancel the subscription at any time from their account dashboard, with 30 days' notice. Cancellation takes effect at the end of the current billing period already invoiced. No pro-rata refund is provided.
After cancellation, the Client has 30 days to export all data from their account dashboard. After this period, data is permanently deleted from the servers.
7. Intellectual property
SaaS solutions
The Client retains ownership of all data entered and stored on YdvSystems platforms. The source code, design, architecture and algorithms of the SaaS solutions remain the exclusive property of YdvSystems. A subscription grants only a non-exclusive, non-transferable right of use for the duration of the subscription.
Freelance services
For custom development services, the Client receives the delivered source code and becomes its owner upon full payment. Internal tools, libraries, frameworks and reusable components developed by YdvSystems remain the property of the Provider, who grants the Client a license to use them within the scope of the delivered project.
8. Liability
YdvSystems commits to providing 99.5% uptime on its SaaS platforms, excluding planned maintenance. Scheduled maintenance is communicated at least 48 hours in advance by email or in-app notification.
YdvSystems shall not be held liable for indirect damages, such as loss of revenue, data or profits, resulting from the use or inability to use the services. In any event, YdvSystems' total liability is limited to the amounts paid by the Client during the preceding 12 months.
9. Force majeure
Neither party shall be held liable for failure to fulfill its contractual obligations if such failure results from a force majeure event as defined under Article 1218 of the French Civil Code, including but not limited to: natural disasters, fire, internet network failures, cyberattacks, government decisions or any other unforeseeable, irresistible and external circumstances.
10. Governing law and jurisdiction
These Terms of Sale are governed by French law. In the event of a dispute, the parties agree to seek an amicable resolution. Failing amicable agreement within 30 days, the dispute shall be brought before the competent court of Narbonne, France.
