Terms and Conditions
§ 1 Scope
(1) These Terms and Conditions apply to all contracts between BeeBack UG (haftungsbeschränkt) (hereinafter "Provider") and the Customer regarding the use of the Invoice-api.xhub API services.
(2) The offering is directed exclusively at entrepreneurs within the meaning of Section 14 of the German Civil Code (BGB), legal entities under public law, and special funds under public law. Contracts with consumers are excluded.
(3) Deviating terms of the Customer are not recognized unless the Provider expressly agrees to their validity in writing.
§ 2 Subject Matter
(1) The Provider provides the Customer with API services for the creation, validation, and processing of electronic invoices.
(2) The exact scope of services is determined by the service and plan overview on the website and the selected plan.
(3) For the duration of the contract, the Customer receives the non-exclusive, non-transferable right to use the API and the associated documentation for their own business purposes. Documents created with the services may be used freely by the Customer.
(4) Services marked as planned are not part of the contract; a claim to them arises only upon their release.
(5) The Provider may change or discontinue free plans with reasonable notice; ongoing paid plans remain unaffected.
§ 3 Conclusion of Contract
(1) The contract is concluded by registration on the website and activation of access.
(2) By registering, the Customer confirms that they belong to the customer group described in § 1 (2) and – if acting for a company – are authorized to represent it.
§ 4 Prices and Payment
(1) The prices stated on the website at the time of contract conclusion apply.
(2) All prices are exclusive of statutory VAT.
(3) Depending on the selected plan, billing takes place monthly or yearly via the payment method stored in the customer account. If payment by invoice has been agreed, the invoice amount is due within 14 days of invoicing.
(4) In case of late payment, the Provider is entitled to block access to the services.
(5) If the Customer exceeds the quota included in their plan, usage beyond the quota is billed at the prices stated on the website, provided the plan allows overage.
§ 5 Customer Obligations
(1) The Customer undertakes to:
- Keep access credentials (API keys) confidential and protect them from unauthorized access
- Not use the services for unlawful purposes
- Not take any measures that could impair the functionality of the services
- Observe the technical documentation and usage restrictions
§ 6 Availability and SLA
(1) The targeted service availability depends on the selected plan (in each case based on the calendar month): 99.5% on the Starter plan and 99.9% on the Premium plan. The Free plan carries no availability commitment.
(2) Planned maintenance work is announced, as a rule at least 48 hours in advance, by email to the address stored in the customer account.
(3) On the Enterprise plan, availability is agreed in an individual Service Level Agreement.
§ 7 Data Protection and Data Security
(1) The Provider processes personal data in accordance with the privacy policy and applicable data protection laws.
(2) Insofar as the Provider processes personal data on behalf of the Customer, a data processing agreement pursuant to Art. 28 GDPR will be concluded; the subprocessors used are named therein.
(3) After the end of the contract, stored data is deleted unless statutory retention obligations require otherwise; the Customer exports required documents before the end of the contract. The obligation to retain their invoices in accordance with the law (in particular the German GoBD) remains with the Customer.
§ 8 Liability
(1) The Provider is liable without limitation for damages arising from injury to life, body, or health, as well as for damages caused intentionally or through gross negligence.
(2) In the case of slight negligence, the Provider is only liable for breaches of material contractual obligations, limited to the typically foreseeable damage.
(3) Without prejudice to paragraph 1, liability for loss of data is limited to the typical recovery effort that would have been incurred had backup copies been made regularly and in a manner appropriate to the risk.
(4) Liability under the German Product Liability Act, for fraudulently concealed defects, and under assumed guarantees remains unaffected. Beyond that, any further liability is excluded.
§ 9 Contract Duration and Termination
(1) The contract is concluded for an indefinite period.
(2) Contracts with monthly billing may be terminated by either party with 30 days' notice to the end of the month; contracts with yearly billing with 30 days' notice to the end of the respective billing year.
(3) The right to extraordinary termination for good cause remains unaffected.
§ 10 Changes to the Terms
(1) The Provider is entitled to change these Terms with effect for the future, provided the change is reasonable for the Customer considering the Provider's interests.
(2) Changes will be communicated to the Customer by email at least 30 days before they take effect. If the Customer does not object within 30 days of receipt of the notification, the amended Terms are deemed accepted; the Provider will separately point out the right to object and this consequence in the notification.
§ 11 Final Provisions
(1) The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods.
(2) The place of jurisdiction is Frankfurt am Main, provided the Customer is a merchant, a legal entity under public law, or a special fund under public law.
(3) Should individual provisions be invalid, the validity of the remaining provisions remains unaffected.
(4) These Terms are available in German and English; in the event of discrepancies, the German version prevails.
