Terms & Conditions

1. Operator and Contract Structure

The Service is operated by Sine Aspera Ad Astra GmbH i.G., Adalbertstraße 56, 80799 Munich, Germany, represented by its managing director Felix Graeber. Commercial register entry pending at Amtsgericht München.

These Terms govern use of Invoice-Converter.com, the web application, paid plans, prepaid conversion credits, External API access, and related support unless a written order form expressly states otherwise. Customer purchase orders, procurement terms, MSAs, DPAs, security addenda, or other customer paper do not apply unless we accept them in a separate signed writing.

Enterprise and production API access are contract-led services. They require approval, an enabled account flag or equivalent provisioning, and, where applicable, a separate order form and Data Processing Agreement.

2. Service Scope

Invoice Converter provides invoice extraction, conversion, validation assistance, and workflow support for structured e-invoicing formats such as XRechnung, ZUGFeRD, Factur-X, UBL, CII, EN 16931, and related profiles. The Service is not legal, tax, accounting, or archiving advice.

You are responsible for source-data accuracy, professional review, tax and accounting decisions, buyer requirements, Peppol or portal delivery, ERP import, statutory deadlines, and final use of generated artifacts. Validation proofs and diagnostics are technical evidence produced by the documented pipeline; they are not a guarantee of legal compliance, authority acceptance, buyer acceptance, routing acceptance, or ERP acceptance.

Paid business use may include production workflows, but you must maintain reasonable backup and fallback processes for invoice creation, review, correction, delivery, archiving, deadlines, and buyer or authority acceptance. The Service must not be your sole process for time-critical invoicing obligations.

3. Accounts, Plans, and Payment

Paid features may require subscriptions, prepaid credits, Enterprise billing, or another agreed payment model. You must provide accurate billing information and pay all fees when due. We may suspend paid features for non-payment, chargebacks, failed payment reconciliation, fraud risk, or misuse.

The public money-back guarantee applies only where its own conditions are met. It does not automatically apply to Enterprise order forms, prepaid API credits, API validation failures, source-document insufficiency, unsupported buyer requirements, or downstream rejection by buyers, authorities, networks, or ERP systems.

For External API usage, one API credit or billable unit is consumed when a conversion request is accepted for processing. If the request cannot be accepted after a credit was reserved, the credit is refunded according to the API credit ledger. Validation failures after acceptance do not automatically create a refund right.

4. External API Terms

API access is gated and may be approved, limited, paused, or withdrawn. API keys are confidential server-side credentials. You must not embed them in browser applications, mobile applications, public repositories, client-side code, logs, screenshots, support tickets, or any location where unauthorized parties may access them.

You are responsible for all activity under your API keys unless the activity resulted from our breach. You must rotate or revoke keys that may be compromised. We may throttle, reject requests, rotate or revoke keys, suspend tenants, or block traffic where necessary for security, abuse prevention, legal or compliance risk, non-payment, excessive load, platform stability, subprocessor protection, or protection of other customers.

API access is for your internal business purposes only. You may not resell, sublicense, white-label, expose, proxy, or operate the API as part of a public third-party-facing product, service bureau, or shared service unless expressly agreed in a separate partner agreement.

Additive API changes may be made at any time. We try to avoid breaking changes within a stable version where commercially reasonable, but may make breaking changes for security, legal, compliance, abuse-prevention, subprocessor, infrastructure, or material product reasons. We do not promise indefinite legacy support.

5. Availability and Support

We provide the Service using commercially reasonable efforts. Business-hours support may be available for paid B2B and Enterprise/API customers, but no uptime, response-time, processing-time, delivery-time, validation-availability, or support SLA applies unless expressly agreed in a separate written order form.

Support targets, onboarding statements, or documentation estimates are non-binding unless expressly stated as binding in a written order form. No contractual penalties, liquidated damages, or automatic service credits apply unless separately agreed in writing.

6. Customer Data and Permitted Use

You retain ownership of uploaded invoices and other customer content. You grant us the limited rights necessary to provide, secure, troubleshoot, support, and improve the Service for you, and to comply with legal obligations. Customer invoice content is not used for model training, reusable datasets, benchmarking, or product analytics unless you give explicit written permission.

You must not upload special-category personal data, criminal-offence data, payment-card data, identity documents, passwords, secrets, HR records, healthcare records, or unrelated sensitive datasets unless strictly necessary and expressly agreed in writing. If such data appears incidentally in invoice content, you remain responsible for ensuring that the upload is lawful, necessary, and minimized.

You must not use the Service as an autonomous decision system or as the sole basis for legal, tax, accounting, creditworthiness, insurance, employment, healthcare, public benefit, sanctions, fraud, or other high-risk regulated decisions.

7. Privacy and Data Processing

Our Privacy Policy explains controller-side processing such as account, billing, product, analytics, support, and security processing. Where we process invoice content on behalf of a business customer, our Data Processing Agreement applies.

Data retention follows the standard retention model described in the Privacy Policy and DPA. We do not provide customer-specific retention schedules, data residency commitments, or custom deletion workflows unless expressly agreed in writing.

8. Security Testing and Audit Requests

You may not conduct production penetration tests, vulnerability scans, load tests, social engineering, destructive testing, source-code access attempts, infrastructure access attempts, or similar security testing without prior written approval.

For Enterprise/API customers, we may provide remote evidence such as our DPA, subprocessor list, TOMs, retention summary, incident process, and reasonable written security questionnaire responses. On-site audits, source-code access, infrastructure access, secrets, credentials, or access to other tenants are not included unless separately agreed in writing.

9. Liability

For paid B2B customers, our ordinary contractual liability for slight negligence applies only where an essential contractual obligation is breached and is limited to the net fees paid by the customer to us in the twelve months before the event giving rise to the claim, but never more than EUR 1,000 in total for all claims arising from that event.

To the extent legally permitted, we are not liable for indirect damages, consequential damages, lost profits, lost revenue, lost savings, business interruption, tax penalties, buyer rejection, authority rejection, replacement services, loss of goodwill, or damage caused by your missing review, fallback, archiving, delivery, or deadline processes.

Nothing in these Terms limits liability for intent, gross negligence, injury to life, body, or health, liability under the German Product Liability Act, or any other liability that cannot legally be limited. Mandatory consumer rights remain unaffected.

10. Termination

You may terminate your account by contacting contact@invoice-converter.com. We may suspend or terminate access if you violate these Terms, fail to pay, create legal or security risk, misuse the Service, exceed acceptable operational load, or endanger the platform, subprocessors, or other customers.

11. Governing Law and Contact

German law applies, excluding conflict-of-law rules and the UN Convention on Contracts for the International Sale of Goods. For merchants and business customers, the courts at our registered seat have jurisdiction where legally permissible. Mandatory consumer jurisdiction rules remain unaffected.
