Terms of Service

Last updated: 2026-09-16

1. Provider, Scope and Order of Precedence

These Terms govern the use of savien, a B2B SaaS platform for coordinating merchants, suppliers, orders, shipments, documents and related processes.

The provider and contractual partner is Davis Gabriels Kalnozols, trading under the business name “savien”, Meierberger Str. 14, 31737 Rinteln, Germany (“savien”).

These Terms apply exclusively to businesses, legal entities under public law and special funds under public law. savien is not directed at consumers. Consumer use is permitted only if expressly agreed by us in text form and if the required consumer information is provided.

Deviating customer terms apply only if expressly accepted by us in text form. In case of conflict, the following order applies: individual agreement, Data Processing Agreement for data protection matters, service description or quote, these Terms, annexes such as SLA, TOM, Subprocessor List and Acceptable Use Policy.

1.1 Contract Language and Language Precedence

These Terms and the incorporated annexes are provided in German and English. Both versions are maintained from the same source and carry the same version.

In the event of any discrepancy in substance or any question of interpretation, the German version alone prevails. The English version is a translation for information purposes and does not create different rights or obligations. This applies even where the contract was concluded in English or communication was conducted in English.

The contract and communication languages are German or English.

2. Subject Matter

savien provides cloud-based software. The platform enables in particular:

• Management of company accounts, users, roles and permissions.
• Connections between merchants and suppliers.
• Management of items, catalogues, prices, orders, shipments and returns.
• Upload and exchange of documents.
• Comments, notifications and email communication.
• Subscription and payment management.
• Optional integrations, such as BillBee.
• Export and deletion functions within the available platform features.

The specific feature scope is determined by the subscribed plan, service description, application and any individual agreement.

Merchants and suppliers conclude contracts for goods and their delivery with each other. savien does not become the seller or buyer and does not represent either party. Goods prices, payment and delivery terms, transfer of risk and remedies for defects are governed by the terms validly agreed between those parties and applicable law. These SaaS Terms do not replace those agreements.

savien is an operational B2B tool. It does not replace legal, tax, customs, product compliance or accounting review and does not provide individual compliance advice for the customer's goods, supply chains or target markets.

2.1 Recurring Orders

The customer may configure an interval for recurring procurement.

When due, the automation creates a draft order only. It does not send any order to the supplier. An order is placed with legal effect only once an authorised user of the customer reviews the draft and expressly sends it. Declarations towards the supplier are therefore always made by the customer, never by savien.

The customer activates, pauses, skips and deletes recurring orders themselves. Every run is logged with a timestamp.

The automation does not verify changes to prices, articles, quantities, availability or supplier assignments. The customer must check each draft for accuracy and currency before sending it. If a draft cannot be created because data is missing, articles were removed or a connection ended, no order arises; there is no entitlement to uninterrupted draft creation.

2.2 Invoicing Function and E-Invoicing

savien provides technical functions to generate and make available invoice documents in PDF format from order and delivery data.

The customer remains the issuer of the invoice. The customer is solely responsible for the content, the completeness of mandatory particulars, the correct VAT treatment and the commercial and tax law accuracy and archiving of its invoices. savien owes no tax review and gives no assurance that a generated document meets the requirements of a particular recipient, authority or target market.

A plain PDF is not an electronic invoice within the meaning of the German rules on mandatory e-invoicing applicable since 1 January 2025. It qualifies as an "other invoice". Where the customer is obliged to issue structured electronic invoices under EN 16931, the customer must use a suitable process of its own until corresponding functions are available.

We will inform customers in good time once savien supports structured formats. Until then, the invoicing function does not replace the customer's own invoicing or accounting system.

3. Contract Formation and Electronic Commerce

Registration creates only a free account-use agreement. Accepting an invitation, connecting with a business partner or productive use alone does not create a paid subscription.

A paid subscription is formed only when an owner or a person demonstrably authorised for billing and contract formation expressly confirms the payer, plan, price, billing period, renewal, cancellation effect and tax notice in checkout. Before the order is submitted, the incorporated versions of the Terms, DPA, Acceptable Use Policy and SLA are displayed and made permanently available.

For online orders, we provide technical means to correct input errors and confirm receipt electronically to the extent required by applicable law, in particular Section 312i German Civil Code. The customer can access and store the contractual terms, including all incorporated legal documents, at contract conclusion. Acceptance is recorded with document ID, version, content hash, language, timestamp, organisation, user and authority role so that the agreement can be reconstructed from the record. Different, equivalently documented processes may apply for individually negotiated B2B contracts.

Trials, pilots or free plans may be limited in functionality, time or volume. There is no entitlement to continuation of free services unless individually agreed.

3.1 Free Trial of the First Monthly Connection

The first monthly connection is free of charge for 90 days after checkout is completed.

The trial is triggered only by the same express checkout that also establishes the paid subscription. In that checkout, the customer simultaneously confirms the paid continuation after the trial ends. Neither a trial nor a paid subscription arises from registration, an invitation, a connection or mere use.

After the 90 days, the connection automatically continues as the confirmed paid subscription. The customer may cancel at any time until the end of the trial; in that case no payment obligation arises. We notify the customer in text form, in good time before the trial ends, of the upcoming start of the payment obligation and of the option to cancel.

The trial applies once per organisation and only to one connection on the monthly plan.

4. User Accounts, Roles and Permissions

The customer is responsible for managing user accounts, roles and permissions. Credentials must be kept confidential. The customer must notify us without undue delay if an account is compromised or misuse is suspected.

The customer must ensure that only authorised persons have access to savien and that departing employees, contractors or business partners are removed in a timely manner.

Actions performed through customer user accounts are attributed to the customer to the extent they originate from the customer's sphere of responsibility.

5. Customer Obligations

The customer agrees to:

• Use savien only lawfully, in accordance with the contract and in the intended B2B context.
• Not upload unlawful, infringing, misleading or security-compromising content.
• Not use malware, automated attacks, scraping, spam or circumvention of technical safeguards.
• Process personal data only on a sufficient legal basis.
• Not submit special categories of personal data under Art. 9 GDPR or data under Art. 10 GDPR unless expressly agreed in advance.
• Independently verify business data, prices, tax information, customs information, delivery data, product information and documents.
• Comply with required consents, information duties, works council/co-determination requirements and agreements towards their own users, employees and business partners.
• Observe local legal requirements where savien is used outside Germany or the EU.
• Secure connected third-party accounts, API keys and integrations.

Further rules are set out in the Acceptable Use Policy.

6. Content and Customer Data

The customer retains ownership of its data and content. We receive the right to store, process, transmit and display customer data to the extent necessary for providing, securing, troubleshooting and billing savien and for performing this contract.

To develop savien further we use exclusively aggregated or anonymised usage and error data that can no longer be attributed to any person or customer. Any use of customer content beyond this for product improvement, benchmarking or model training takes place only on separate instruction from, or agreement with, the customer.

The customer warrants that it is authorised to use, process and transmit the submitted content. The customer is responsible for content submitted by its users or connected business partners.

We do not generally review customer data in advance. Where we receive specific indications of legal violations, security risks or breaches of contract, we may review content, contact the customer, restrict or remove content and take further necessary measures.

7. Data Protection and Processing

Personal data processing is governed by the Privacy Policy and, where savien acts as processor, by the Data Processing Agreement pursuant to Art. 28 GDPR.

The customer remains controller for personal data processed within savien where the customer determines the purposes and means of processing, in particular data relating to its employees, suppliers, merchants, contact persons and other business partners.

If the customer submits third-party personal data to savien, the customer is responsible for informing data subjects, legal bases, data subject rights and any co-determination requirements.

8. Third-Party Services and Integrations

savien may use third-party services or provide optional integrations, in particular Supabase, Vercel, Stripe, Resend and BillBee.

Optional integrations are activated by the customer. The customer is responsible for the lawfulness of the connection, credentials, configuration and compliance with third-party terms.

Third-party providers may apply their own contractual, privacy and use terms. We do not guarantee availability or error-free operation of third-party services to the extent they are outside our responsibility.

We may restrict or deactivate integrations where required for security, legal, provider-related or stability reasons.

9. Prices, Payment and Billing

Prices, billing intervals, trial periods and plan limits are set out in /pricing, the checkout, the quote or an individual agreement.

Unless stated otherwise, all prices are net amounts plus applicable VAT. Payments are processed via Stripe or another agreed payment method.

In case of payment default, we may restrict or suspend access after reasonable notice if the customer does not remedy the default in time and the suspension is proportionate.

The customer is responsible for the accuracy of billing, tax and company information.

10. Availability, Maintenance and Support

We strive for high availability of savien. Availability, maintenance windows, support hours and response targets are set out in the Support and Availability Terms or an individual agreement.

No availability guarantee applies to outages caused by force majeure, internet disruptions, third-party services, emergency maintenance, misuse, security incidents or circumstances outside our control.

The customer must report disruptions in a comprehensible manner and reasonably cooperate in analysis and remediation.

11. Platform Changes

We may further develop, update and modify savien features, provided the customer's legitimate interests are reasonably considered. We will notify the customer in advance of material restrictions to subscribed core functionality unless short-term action is required for security, legal or operational reasons.

We may implement urgent changes where required to address security risks, comply with law, prevent misuse or maintain platform stability.

12. Term and Termination

The term is determined by the subscribed plan or individual agreement. Monthly or annual subscriptions renew automatically for the respective interval. Unless individually agreed otherwise, the customer may cancel until the end of the current billing period with effect at that period's end; no additional advance notice period applies. Trial cancellation under section 3.1 remains unaffected.

The right to terminate for good cause remains unaffected. Good cause includes material payment default, serious misuse, breach of material contractual obligations, security risks or legal prohibitions.

Termination should be made in text form or through the termination functions provided in the application.

13. Data Export, Switching, Contract End and Deletion

The customer can export its data using the export functions provided in the application. After contract end, access may be deactivated. We delete or anonymise customer data after expiry of statutory retention obligations and technical backup cycles in accordance with the DPA and Privacy Policy.

The customer should prepare necessary exports in good time. Our DPA return obligations and switching obligations remain unaffected. We maintain secure access or an equivalent transfer channel to fulfil them.

To the extent savien qualifies as a data processing service within the meaning of Chapter VI of Regulation (EU) 2023/2854 (EU Data Act), the following applies in addition:

• The customer may request support for switching to another provider, to its own ICT infrastructure or for deletion of exportable data.
• Exportable data includes in particular company, user, role, connection, item, catalogue, price, order, shipment, return, comment, document, integration and relevant metadata entered by the customer or generated by its use, to the extent attributable to the customer and technically exportable.
• Not exportable are in particular internal security information, internal operational and administration logs, non-customer-specific system metrics, trade secrets, source code, internal models, internal configurations, password hashes, API secrets and third-party data where disclosure would be unlawful. This exception must not unnecessarily impede a permitted switching process.
• Available export formats may include JSON, CSV, PDF and original file formats of uploaded documents. Details depend on the available export functions, APIs and technical capabilities.
• A switching process starts when the customer submits a sufficiently specific switching, porting or deletion request and provides the required target information. The maximum notice period for initiating a switching process is two months.
• We provide reasonable assistance, act with due care to maintain business continuity and inform the customer of known continuity risks.
• After the agreed notice period expires, we carry out the switch without undue delay within a binding transition period of no more than 30 calendar days. If technically infeasible, we notify the customer within 14 working days of receiving the request, explain the technical infeasibility and specify an alternative transition period of no more than seven months. Business continuity is maintained during the transition period.
• The customer may extend the transition period once by a period it considers more appropriate for its purposes. The customer informs us of the requested extension before the current transition period expires.
• The affected contract ends upon successful completion of switching or, if the customer requests deletion instead, upon expiry of the agreed notice period. We confirm termination to the customer. Mandatory switching rights prevail over conflicting term provisions.
• After the transition period, we make exportable data available for retrieval for at least 30 calendar days. A longer retrieval period may be agreed.
• After the retrieval period, we delete exportable customer data and digital assets. For personal data, the controller's choice, statutory retention exceptions and restricted backup cycle under DPA section 13 apply. A general security or litigation interest does not justify further processing of customer data on behalf of the customer.
• Separate switching charges will not be charged from 12 January 2027. Until then, such charges may only be charged where legally permissible, transparently disclosed in advance and not exceeding the costs directly linked to the switching process. Standard service fees and permissible contractual fees remain unaffected.

Every export triggered through the application contains a manifest with the schema version, export timestamp, number of records per category and the list of non-exportable categories. A SHA-256 checksum is computed over the delivered file, shipped with the file and stored in the account's export log. This allows the customer to verify the completeness and integrity of the export without our involvement.

Data portability rights under Art. 20 GDPR remain unaffected. The product export and the statutory right to data portability are not identical: Art. 20 GDPR covers only certain personal data, whereas the product export also includes non-personal business data.

14. Rights in savien

All rights in savien, software, design, trademarks, documentation and other components remain with us or our licensors.

The customer receives a simple, non-exclusive, non-transferable right to use savien in accordance with the contract for the contract term.

Reverse engineering, copying, resale, rental, white-labelling or use for competing products is permitted only with our prior express consent or where mandatory law allows it.

15. Feedback

The customer may provide feedback, ideas or suggestions. We may use such feedback free of charge to improve savien without disclosing confidential customer data.

16. Warranty

Statutory warranty rights apply, modified to the extent permissible in B2B contracts. savien is provided as SaaS and is not designed to meet every individual process, compliance or ERP requirement without a separate agreement.

The customer must report defects comprehensibly and give us reasonable opportunity to analyse and remedy them. A defect does not exist to the extent an issue is caused by unlawful use, unsuitable customer data, third-party services, incorrect customer configuration or unsupported systems.

17. Liability

We are fully liable for intent, gross negligence, injury to life, body or health, under product liability law and for assumed guarantees.

In cases of simple negligence, we are liable only for breach of material contractual obligations. In such cases, liability is limited to the typical foreseeable damage for this type of contract.

For breach of material contractual obligations, liability also covers indirect damages, lost profits, business interruptions and data loss to the extent typical and foreseeable for this contract. Liability for simple negligence is otherwise excluded. Mandatory statutory liability, including liability to data subjects under Art. 82 GDPR, remains unaffected.

Reasonable customer cooperation with backups that is required by the contract may be considered as contributory negligence under section 254 BGB. Our own backup and recovery obligations are not restricted by this provision.

This liability regime also applies in favour of our employees, officers, vicarious agents and service providers.

18. Indemnification

The customer indemnifies us against justified third-party claims to the extent caused by a breach of contractual duties for which the customer is responsible. Any contributory fault of savien is taken into account. We notify the customer without undue delay, allow reasonable participation in the defence and do not acknowledge claims without its consent unless necessary to avert imminent harm. Only necessary and reasonable defence costs are recoverable.

19. Confidentiality

The parties shall keep confidential information of the other party confidential and use it only for contractual purposes. Confidential information includes in particular non-public technical, commercial, contractual and operational information.

This obligation does not apply to information that is publicly known, lawfully obtained from third parties, independently developed or required to be disclosed by law.

20. Security and Incident Cooperation

We implement technical and organisational measures in accordance with the TOM and the current state of the platform. The customer is responsible for appropriate security measures within its own responsibility, in particular secure devices, strong passwords, MFA use, permission management and protection of API access.

Security incidents or suspected incidents must be reported without undue delay to security@savien.io. The parties reasonably support each other in investigation, containment, documentation and legally required notifications.

To the extent the customer or savien is subject to NIS2/BSIG, KRITIS, DORA or comparable security and reporting duties, those duties remain unaffected. The customer is responsible for its own applicability assessment.

21. International Use, Export Controls and Sanctions

savien may in principle be used internationally. The customer is responsible for ensuring that its use is lawful in the respective target markets.

The customer may not use savien if this violates applicable export control, sanctions, embargo or trade restriction rules of the EU, Germany, the USA or other relevant jurisdictions. The customer may not use savien for prohibited goods, services, dual-use items, sanctioned persons or sanctioned territories.

We may suspend access or terminate the contract if use violates such requirements or if there is a material risk thereof.

22. Amendments

For existing contracts, amendments to these Terms and the agreed service, price, liability or support conditions require the customer's express consent. Silence, failure to object or continued use does not constitute consent.

We send proposed amendments in text form at least 30 calendar days in advance, stating their content, reason and intended effective date. Without consent, the existing agreement continues. Statutory termination rights and contractually permitted ordinary termination remain unaffected. New terms are not incorporated retroactively.

Mandatory law and the already agreed procedures for technical security measures and subprocessors remain applicable. They do not establish a general right to change prices or main performance obligations unilaterally.

23. Governing Law and Jurisdiction

German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. The exclusive place of jurisdiction for all disputes arising from or in connection with these Terms is Rinteln, provided that the customer is a merchant, legal entity under public law or special fund under public law.

Mandatory consumer protection provisions remain unaffected if savien is exceptionally offered to consumers.

24. Miscellaneous

If any provision of these Terms is or becomes invalid, the validity of the remaining provisions remains unaffected. The parties will replace the invalid provision with a valid provision that comes as close as legally permissible to the economic purpose.
