Licence terms

Version: 9 November 2026. Businesses only. This is a translation; the German version prevails.

1. Scope and provider

1. ValiBeleg is provided by Denis Wagner, Sprottauerstr. 101, 90475 Nürnberg, Germany (sole proprietorship), e-mail support@valibeleg.com (“Provider”).
2. These terms apply to all use of the ValiBeleg software including the trial, updates and documentation (“Software”).
3. ValiBeleg is offered exclusively to businesses within the meaning of § 14 of the German Civil Code (BGB), legal entities under public law and special funds under public law (“Customer”). Contracts with consumers are excluded.
4. By installing or first using the Software, the Customer accepts these terms. Deviating terms of the Customer only apply if the Provider agrees to them in writing.

2. Trial

1. The Customer may test the Software free of charge with all features for 30 days from the first start, solely to evaluate whether to buy a licence.
2. The trial is bound to the computer on which it was installed. Resetting or extending the trial period by reinstalling, deleting files or changing the system time is not permitted.
3. For the trial, the Provider is only liable for intent and gross negligence; section 8 (3) remains unaffected.

3. Licence types and scope

1. For the paid term, the Provider grants the Customer a simple, non-transferable and non-sublicensable right to use the Software for its own business purposes.
2. A workstation is one installation on one computer. Each installation is activated with the licence key; the number of simultaneous activations is limited to the number purchased. An activation stays bound to the computer on which it was made; transferring it to another computer is not provided for.
3. The company licence is issued as a signed licence file in the Customer's name. Scope and term follow from the respective offer.
4. During the term, the Customer receives all updates, in particular adjustments to new versions of XRechnung, ZUGFeRD/Factur-X and the KoSIT validation rules.

4. Subscription, payment and cancellation

1. Single-user and team licences are sold as annual subscriptions through our payment provider Lemon Squeezy, LLC. Lemon Squeezy acts as merchant of record, issues the invoice and remits VAT; its terms additionally apply to the purchase.
2. The subscription renews for another year unless cancelled before the end of the current term. It can be cancelled at any time with effect from the end of the term via the link in the purchase confirmation or by e-mail to support@valibeleg.com.
3. Fees already paid are not refunded pro rata on cancellation.
4. The Provider may change prices for future terms by e-mail at least 6 weeks before renewal. In that case the Customer may cancel with effect from the end of the current term.

5. After the trial or licence ends

1. After the trial or a licence ends, the Software no longer performs new checks.
2. All stored invoices, check results and reports remain readable, printable and exportable without time limit so that the Customer can meet its retention obligations (e.g. under GoBD). This use remains permitted without a licence.
3. A licence with online activation is confirmed online regularly (about every 30 days). If the computer is offline for longer, the Software keeps working for another 30 days before new checks are blocked.

6. Restrictions

The Customer may not:

• rent, sell or pass on the Software to third parties, or operate it as a service for other companies (e.g. checks on behalf of clients), unless agreed in writing;
• pass on licence keys or licence files, or use them beyond the number purchased;
• circumvent or modify the licence check, trial period or copy protection;
• decompile or reverse engineer the Software, except where mandatorily permitted by § 69e of the German Copyright Act (UrhG);
• remove copyright notices, trademarks or licence notices.

Tax advisers and accounting service providers who want to use ValiBeleg for clients can get a company licence on request.

7. Data and privacy

1. Invoices, check results and reports are processed and stored exclusively on the Customer's computer or network drive. The Provider has no access to invoice data.
2. Only the following is transmitted online: the licence key and a device name for activation and confirmation (to Lemon Squeezy), and the update check (to download.valibeleg.com, with no personal data other than the IP address).
3. The Customer is responsible for backing up locally stored data.
4. Details are in the privacy policy at valibeleg.com/en/privacy/.

8. Warranty and liability

1. ValiBeleg technically checks e-invoices against the published rules (EN 16931, XRechnung, ZUGFeRD/Factur-X, KoSIT validation rules) and against data the Customer has stored (e.g. purchase order check). The check result is a working aid. It does not replace the tax, legal or factual review by the Customer or its tax adviser; the Customer decides on payment, booking and input VAT deduction.
2. The Provider remedies defects that significantly impair contractual use within a reasonable period by an update or workaround. No particular availability or response time is promised unless agreed separately.
3. The Provider is liable without limitation for intent and gross negligence, for injury to life, body or health, and under the German Product Liability Act.
4. For slightly negligent breach of essential contractual obligations, the Provider is only liable for typical, foreseeable damage, limited to the fees paid by the Customer in the last 12 months. Otherwise, liability for slight negligence is excluded.
5. Liability for data loss is limited to the effort that would have been required for restoration if the Customer had made regular backups.

9. Third-party components

ValiBeleg contains open-source components that are subject to their own licences. For each component, its licence takes precedence over these terms; the list is supplied with the Software as DRITTANBIETER.txt.

10. Final provisions

1. German law applies, excluding the UN Convention on Contracts for the International Sale of Goods.
2. Place of jurisdiction is Nürnberg, Germany, if the Customer is a merchant, a legal entity under public law or a special fund under public law.
3. The Provider may change these terms with effect for future terms and announces changes by e-mail at least 6 weeks in advance. The Customer may cancel before they take effect.
4. Should any provision be invalid, the validity of the remaining provisions is not affected.
