Terms and Conditions
Last updated: 2026-04-27
Section 1 — Scope
These Terms and Conditions ("Terms") govern all contracts between YS Development B.V., Prins Hendrikplein 8, 2264 SL Leidschendam, Netherlands (the "Provider") and customers (the "Customer") for the paid services offered on plainvoice.de. A consumer within the meaning of these Terms is any natural person who concludes a legal transaction for purposes that are predominantly neither commercial nor self-employed professional. A business customer is any natural or legal person or partnership with legal capacity acting in the exercise of a commercial or independent professional activity.
Section 2 — Subject matter
The Provider makes available a browser-based application for converting X-Rechnung XML files into CSV, TXT, XLSX, and PDF formats. The basic features (single-file conversion) are free of charge. Against payment of a one-time fee, the Customer acquires a perpetual, non-exclusive licence to use the advanced features ("Plainvoice Pro"), in particular the bulk conversion of multiple files. The licence is represented by a licence key and is non-transferable.
Section 3 — Conclusion of contract
The presentation of services on plainvoice.de does not constitute a legally binding offer, but an invitation to submit an offer. By clicking the purchase button, the Customer submits a binding offer to acquire a licence. The contract is concluded when the Provider accepts the offer by sending the licence key by email.
Section 4 — Prices and payment
The price displayed on plainvoice.de at the time of ordering applies. All prices are inclusive of applicable statutory taxes. Payment is processed via the payment service provider Stripe (Stripe Payments Europe, Limited). Stripe's payment terms and privacy policy apply. An invoice will be sent to the Customer by email upon receipt of payment.
Section 5 — Delivery of service
The licence key will be sent to the email address provided by the Customer immediately after successful payment. The Customer is responsible for ensuring that a valid email address is provided. The Provider endeavours to maintain high availability of the services but does not guarantee uninterrupted availability. Maintenance work and unforeseen outages do not entitle the Customer to a reduction of the fee already paid.
Section 6 — Right of withdrawal (for consumers)
Consumers have a right of withdrawal as follows:
Right of withdrawal
You have the right to withdraw from this contract within 14 days without giving any reason. The withdrawal period is 14 days from the date of conclusion of the contract. To exercise your right of withdrawal, you must inform us (YS Development B.V., Prins Hendrikplein 8, 2264 SL Leidschendam, Netherlands, email: info@plain-cards.com) by means of a clear statement (e.g. a letter sent by post or an email) of your decision to withdraw from this contract. It is sufficient for you to send your communication concerning the exercise of the right of withdrawal before the withdrawal period expires.
Consequences of withdrawal
If you withdraw from this contract, we shall reimburse all payments received from you, without undue delay and no later than fourteen days from the day on which we receive notification of your withdrawal from this contract. We will use the same means of payment as you used for the initial transaction unless expressly agreed otherwise with you; in no event will you be charged any fees as a result of such reimbursement.
Expiry of the right of withdrawal
The right of withdrawal expires in the case of a contract for the supply of digital content not supplied on a tangible medium if the Provider has begun performance of the contract after the consumer has expressly agreed that the Provider may begin performance before the expiry of the withdrawal period and has acknowledged that the consumer thereby loses the right of withdrawal. We draw attention to the fact that we obtain this agreement and acknowledgement at checkout via a checkbox.
Section 7 — Warranty
The statutory warranty rights apply. The Provider warrants that the software, when used as intended, substantially performs the functions described in the service description. Defects must be reported to the Provider promptly by email.
Section 8 — Liability
The Provider is liable without limitation for intent and gross negligence, for injury to life, body, or health, under the provisions of product liability law, and to the extent of any guarantee given by the Provider. In the event of slightly negligent breach of a material contractual obligation (cardinal obligation), the Provider's liability is limited in amount to the loss that was foreseeable and typical for this type of transaction. All other liability is excluded.
Section 9 — Data protection
Information on the processing of personal data is contained in the privacy policy.
Section 10 — Applicable law and jurisdiction
Dutch law applies, excluding the UN Convention on Contracts for the International Sale of Goods. For consumers, this choice of law applies only to the extent that the protection afforded by mandatory provisions of the law of the country in which the consumer has their habitual residence is not thereby withdrawn. For customers who are merchants, legal entities under public law, or special funds under public law, the exclusive place of jurisdiction for all disputes arising from this contract is the registered office of the Provider.
Section 11 — Amendments to these Terms
The Provider reserves the right to amend these Terms. For contracts already concluded, the Terms published at the time of conclusion of the contract continue to apply unchanged.
Section 12 — Severability
Should any provision of these Terms be or become invalid, the validity of the remaining provisions shall not be affected.
Section 13 — Contract language
These Terms are available in German and English. Both versions are equally binding. In the event of discrepancies, the version in the language in which the purchase was made shall prevail.
