Terms of Service

1. Scope and contract structure These Terms of Service govern access to and use of the TaxRouter software-as-a-service offering by business customers, tax advisors, accounting firms, finance teams, and their authorized users. If you enter into a separate written order form, subscription agreement, or Data Processing Addendum with TaxRouter, that document supplements these Terms and will prevail to the extent of a conflict. 2. Service description TaxRouter provides a workspace-based software service that helps customers connect Amazon Seller Central accounts, sync source data such as VAT transaction and settlement report data, organize consultant and client workspaces, and generate DATEV-related export files. The exact feature set may depend on the current product version, selected plan, and technical availability of connected third-party systems. 3. Eligibility and accounts You may use TaxRouter only for business or professional purposes and only if you have the authority to bind the relevant organization. You must provide accurate account information, keep credentials confidential, enable reasonable security measures for authorized users, and promptly notify us if you become aware of unauthorized access or another security incident. 4. Customer responsibilities You are responsible for the lawfulness, accuracy, and suitability of the data you submit to TaxRouter or pull into TaxRouter from third-party systems. You must ensure that you have all rights, permissions, notices, and legal bases required to connect Amazon accounts, import files, process personal data, and generate or use DATEV exports. TaxRouter supports operational workflows only; you and your tax advisor remain responsible for reviewing outputs before accounting entries, filings, or business decisions are made. 5. Acceptable use You may not use TaxRouter to violate applicable law, infringe third-party rights, circumvent security, interfere with the service, introduce malicious code, or attempt to gain unauthorized access to accounts, systems, or data. Except to the extent mandatory law allows it, you may not reverse engineer, decompile, or otherwise attempt to derive source code or underlying trade secrets from the service. 6. Customer data and data processing As between the parties, Customer retains all rights in Customer data. Customer grants TaxRouter the limited rights necessary to host, process, transmit, and display Customer data solely to provide, secure, maintain, and support the contracted service. Where TaxRouter processes personal data on Customer's behalf, the parties will rely on the applicable data processing terms and the Data Processing Addendum. 7. Third-party services TaxRouter depends in part on third-party services and infrastructure, including Amazon Seller Central and related APIs, email delivery providers, hosting providers, and Customer-controlled systems such as DATEV environments or internal workflows. TaxRouter is not responsible for third-party products, outages, API changes, account restrictions, or data supplied by third parties. You remain responsible for complying with the terms that govern your third-party accounts and systems. 8. Availability, maintenance, and changes TaxRouter will use commercially reasonable efforts to make the service available and secure. We may perform maintenance, apply security updates, suspend access where reasonably necessary to protect the service or other customers, and modify features to reflect legal, technical, or product requirements. We do not promise that every feature will remain available forever or that the service will be uninterrupted or error-free at all times. 9. Fees and payment If you purchase a paid plan or sign an order with TaxRouter, you must pay the agreed fees and applicable taxes in accordance with that plan or order. Unless otherwise agreed, fees are due without deduction and are non-refundable except where mandatory law requires otherwise. TaxRouter may suspend access for overdue amounts after reasonable notice. 10. Intellectual property and feedback TaxRouter and its licensors retain all rights, title, and interest in the service, software, documentation, and all related intellectual property. No rights are transferred to you except the limited right to use the service during the applicable term. If you provide ideas, suggestions, or feedback, TaxRouter may use them without restriction or compensation. 11. Confidentiality Each party must protect the other party's confidential information with reasonable care and may use it only for performing or receiving the contractual services, complying with law, or enforcing the agreement. Confidential information does not include information that is public through no breach of duty, was already lawfully known, is independently developed, or is lawfully received from a third party without confidentiality obligations. 12. Warranty disclaimer and professional responsibility TaxRouter is a software tool for workflow support. It does not provide legal, tax, audit, or accounting advice, and it does not replace professional review. Except as expressly agreed in writing, TaxRouter provides the service on the basis of the current product state and disclaims specific results, uninterrupted availability, and compatibility with every third-party environment to the maximum extent permitted by law. 13. Liability TaxRouter is liable without limitation for intent, gross negligence, injury to life, body, or health, and under mandatory product liability law. In the case of slight negligence, TaxRouter is liable only for the breach of a material contractual obligation and only for the foreseeable damage typical for this type of contract. To the extent permitted by law, liability for indirect damages, consequential damages, and lost profits is excluded. These limitations also apply in favor of TaxRouter's employees, agents, and subcontractors. 14. Term and termination These Terms apply from the time you first access or use the service and continue for the duration of the applicable subscription, order, or ongoing use unless terminated earlier. Either party may terminate for cause if the other party materially breaches the agreement and fails to cure within a reasonable period after notice, or immediately where the breach cannot reasonably be cured. On termination, access rights end, and Customer data will be returned or deleted in accordance with the applicable contract, Data Processing Addendum, and legal retention requirements. Customer should export needed data before the effective termination date. 15. Governing law and venue These Terms are governed by the laws of the Federal Republic of Germany, excluding its conflict-of-law rules and the UN Convention on Contracts for the International Sale of Goods. If Customer is a merchant, legal entity under public law, or special fund under public law, the exclusive venue for disputes arising out of or in connection with these Terms is Hamburg, Germany. Mandatory consumer protection law remains unaffected where applicable.
