Terms of Service

Version 1.1, effective 2026-06-24. These terms apply between the merchant installing the Faktwise app ("you") and Emanuel José Vargas Luís, sole trader (Einzelunternehmer), Portugal, operating Faktwise ("we"). Our full provider details are in the imprint. By installing or using the app you accept these terms. The Data Processing Agreement is part of these terms.

1. The service

Faktwise is a Shopify app that generates invoices and credit notes (including e-invoice formats such as ZUGFeRD and XRechnung), stores them, and provides related exports and reports. The service is provided for business use only (B2B); it is not offered to consumers.

2. Your responsibilities

• You provide accurate business details (name, address, VAT identification, tax settings). Invoices are generated from your data and your configuration; you remain responsible for their content and for your tax filings.
• Faktwise is software, not tax advice. Configuration choices (for example the small business scheme or OSS settings) should be confirmed with your tax advisor.
• You must have the right to use the customer data your store sends to the app.

3. Fees

Pricing is shown on the pricing page and billed through Shopify's billing system on your Shopify invoice. Our refund policy applies. We may change prices for future billing periods with prior notice through the app or by email; price changes never apply retroactively.

4. Availability and support

We aim for high availability but do not guarantee uninterrupted operation. Invoice generation is queued and retried automatically after outages. Support: support@faktwise.com.

5. Data and retention

Data handling is described in the privacy policy and the DPA. After uninstallation, operational data is deleted and issued invoices remain archived for the statutory retention period; you should export your archive before uninstalling.

6. Liability

We are liable without limitation for intent and gross negligence, for injury to life, body or health, and where mandatory statutory liability applies (for example under the Product Liability Act).

For the simple (ordinary) negligent breach of an essential contractual duty, that is a duty whose fulfilment is essential to the proper performance of the contract and on whose observance you may regularly rely (a cardinal duty), our liability is limited to the typical damage foreseeable at the time the contract was concluded.

Any further liability for simple negligence is excluded. In particular, we are not liable for indirect damages, lost profits, or for tax outcomes resulting from incorrect data or configuration you provided. The limitations in this section do not apply to the cases of unlimited liability stated in the first paragraph above.

7. Termination

You can end the contract at any time by uninstalling the app. We may terminate with reasonable notice or immediately for serious cause (abuse, non-payment, illegal use).

8. Governing law and place of jurisdiction

These terms and the contractual relationship are governed by the law of the Federal Republic of Germany, excluding its conflict-of-law rules and the UN Convention on Contracts for the International Sale of Goods (CISG). Because the service is offered to businesses only (B2B), the exclusive place of jurisdiction for all disputes arising from or in connection with this contract is the provider's registered seat in Lisbon, Portugal, to the extent such an agreement is legally permissible. Our provider address is set out in the imprint.

9. Final provisions

If a provision of these terms is invalid, the rest remains in force. We may update these terms for the future with notice; continued use after the notice period counts as acceptance.
