General Terms and Conditions (AGB)

This English version is provided for convenience. The German version is legally binding.

§ 1 Scope

1. These General Terms and Conditions (Allgemeine Geschäftsbedingungen, "AGB") apply to all services provided by BelegBridge Compliance Software (hereinafter the "Provider") under the name BelegBridge.
2. The services are offered exclusively to businesses within the meaning of § 14 BGB, legal entities under public law and special funds under public law (hereinafter the "Customer" or "User"). Consumers within the meaning of § 13 BGB are excluded. By using the services, the User confirms that they act in the course of their trade, business or profession.
3. Conflicting or deviating terms of the Customer do not apply unless the Provider expressly agrees to them in writing.

§ 2 Subject matter and current scope of services

1. The Provider currently offers free of charge: a web validator for electronic invoices (XRechnung and ZUGFeRD/Factur-X), a translator for validation messages, a visualizer that renders invoices in a readable form, and the corresponding public API endpoints.
2. The paid bridge (automatic creation of electronic invoices from Stripe, PayPal or email sources, seller profiles, dispatch to buyers and DATEV) is in preparation and is offered as early access. Registering on the waitlist does not constitute a contract for paid services and does not create any obligation to pay.

§ 3 Free validator and visualizer

1. The validator technically checks uploaded files against the official validation rules – in particular the KoSIT validator with the XRechnung configuration and Mustang/veraPDF for PDF/A conformance – in the versions deployed at the time of the check. The visualizer renders the content of an invoice in a human-readable form and performs arithmetic plausibility checks.
2. The results are technical notes. They do not constitute tax or legal advice and do not replace a review by a tax adviser (Steuerberater). A positive result only means that no violations of the deployed rule sets were found at the time of the check.
3. The Provider does not become the issuer of the invoices checked. Responsibility for the correctness and completeness of an invoice under § 14 UStG (German VAT Act) remains with the invoice issuer.
4. Uploaded files are processed exclusively in volatile memory and are not stored (see the Privacy Policy).

§ 4 Availability and fair use

1. There is no entitlement to a particular availability of the free services; no service level is agreed. The Provider may restrict, change or discontinue the free services at any time, in particular for maintenance, security or capacity reasons.
2. To ensure fair use and to protect against abuse, the Provider limits the number and size of requests (currently up to 15 MB per file, plus request limits per time period). Automated mass queries that circumvent these limits are not permitted.

§ 5 User obligations

1. The User may only upload files that they are entitled to process, in particular with regard to personal data of third parties contained in invoices.
2. The User must not upload malware, deliberately manipulated files or content intended to impair the services, and must not attempt to bypass security measures or rate limits.
3. The User is responsible for checking results for plausibility before relying on them for tax purposes.

§ 6 Paid plans (early access)

1. The paid plans Starter, Pro and Agency, their scope of services, conversion quotas and the number of seller tax IDs (VAT ID or tax number) that can be registered per plan are described on the pricing page.
2. Conversion quotas apply per calendar month and reset on the first day of each month – also for annual billing. Unused quotas do not carry over.
3. The seller's mandatory details (in particular name and tax IDs) are always taken from the seller profile stored in the customer account; the Customer is responsible for their accuracy.
4. Subscriptions are billed through a merchant-of-record payment provider (e.g. Paddle or Lemon Squeezy), which acts as the seller towards the Customer for the payment transaction.
5. The paid services are currently in preparation (early access). Detailed contractual terms – in particular term, notice periods and the conclusion of a data processing agreement – will be provided before booking and apply only once a paid plan has been booked.

§ 7 Retention and archiving

1. BelegBridge is not an archiving system. Invoice contents are not stored by the Provider.
2. The Customer remains solely responsible for complying with statutory retention obligations (§ 14b UStG, § 147 AO and GoBD), in particular for storing invoices in an unalterable and machine-readable form for the statutory retention period (currently eight years for invoices).

§ 8 Liability

1. The Provider is liable without limitation for intent and gross negligence, for injury to life, body or health, under the German Product Liability Act (Produkthaftungsgesetz) and to the extent a guarantee has been given.
2. In cases of slight negligence, the Provider is liable for paid services only for the breach of essential contractual obligations (cardinal obligations), i.e. obligations whose fulfilment makes the proper performance of the contract possible in the first place and on whose compliance the Customer may regularly rely. In this case, liability is limited to the foreseeable damage typical for this type of contract.
3. For the free services, the Provider is liable – in accordance with § 521 BGB (applied analogously) – only for intent and gross negligence; paragraph 1 remains unaffected.
4. Any further liability is excluded. The above limitations also apply in favour of the Provider's employees, representatives and vicarious agents.

§ 9 Data protection

Information on the processing of personal data can be found in the Privacy Policy. For the paid bridge, a Data Processing Agreement (AVV) under Art. 28 GDPR will be concluded together with the paid contract.

§ 10 Changes to these terms

The Provider may amend these terms with effect for the future. For paid contracts, the Customer will be notified of changes in text form at least four weeks before they take effect and may object; the details will be governed by the contractual terms for the paid plans.

§ 11 Final provisions

1. These terms are governed by the laws of the Federal Republic of Germany, excluding the UN Convention on Contracts for the International Sale of Goods (CISG).
2. If the Customer is a merchant (Kaufmann), a legal entity under public law or a special fund under public law, the exclusive place of jurisdiction for all disputes arising from or in connection with this contractual relationship is the Provider's registered place of business.
3. Should individual provisions of these terms be or become invalid, the validity of the remaining provisions remains unaffected. The statutory provisions apply in place of the invalid provision.
