1. Introductory Provisions
1.1. These General Terms and Conditions ("GTC") regulate the rights and obligations of Krisztian Eyssen, operating as a Self-Employed Individual/Sole Trader (hereinafter: "Service Provider") and the customers using their services (hereinafter: "Client"), concerning IT services.
1.2. The Client may only use the Service Provider’s services after accepting these GTC. Acceptance of the GTC is constituted, in particular, by the actual use of the service, topping up a prepaid balance, placing an order, or accepting any performance.
1.3. Should the parties enter into a separate written agreement (e.g., individual order, framework agreement), the provisions of these GTC shall remain applicable to matters not regulated therein. In case of discrepancies, the individual agreement shall prevail.
1.4. The appendices at the end form an integral part of these GTC and are valid only together with them. The appendices, along with the GTC, constitute the contractual terms between the Service Provider and the Client. If any matter is regulated differently by these appendices, the specific provision in the appendix shall govern.
1.5. Client Status. The Service Provider’s services are exclusively available to businesses carrying out economic activities (legal entities, sole traders, or companies). In the case of a contract with a consumer, consumer protection rules may result in deviation; the Service Provider reserves the right to refuse to enter into a contract.
1.6. Definitions – Business Day. Business Day: Mon–Fri, 9:00–17:00 (GMT/BST; IANA: Europe/London), excluding UK national public holidays.
2. Subject Matter of the Service
2.1. The Service Provider primarily provides cloud-based hosting and associated infrastructure (eYssen Cloud) for the eYssen (Section 2.2) and any Odoo-based system. Furthermore, the Service Provider offers hourly-rate professional support in the following areas: implementation consulting, customisation/development, integrations, operation/support (helpdesk), training/consultation.
2.2. eYssen (Product) is a complete Enterprise Resource Planning (ERP) system initiated and maintained by the Service Provider, developed in a community effort. The development is open, integrating work from multiple contributors. Therefore, the Service Provider provides no warranty or guarantee regarding the bug-free operation, fitness for a particular purpose, or continuous availability of eYssen; the product is used “AS IS.”
2.3. Reaction times, capacity, and service levels are determined by the current price list and service description.
3. General Terms of Performance (Hourly Rate, No Guarantee of Outcome)
3.1. Method of Charging. The Service Provider charges exclusively on an hourly rate basis, in units of 0.5 hours commenced (according to the current price list). The Client freely decides on the use of the service; the Service Provider does not undertake to ensure a specific result, deadline, or availability, unless the parties agree otherwise in writing.
3.2. Exclusion of Warranty and Justification; Exceptional Bug Fix Commitment a) Exclusion of Warranty. The Service Provider provides no warranty or guarantee for the work. This is justified by the fact that in ERP and IT systems, the final operation is significantly influenced by the Client’s processes, data, user habits, external integrations, and third-party components/updates, over which the Service Provider has no full control. The Service Provider ensures professional diligence but does not guarantee bug-free operation, fitness for a particular purpose, or continuous availability. b) Exception – eYssen System Running in eYssen Cloud without Custom Add-ons. The Service Provider undertakes to fix reproducible bugs found in the eYssen (core) system that contradict the documented functionality, at its own expense, if the following conditions are met cumulatively: (i) the system runs in the Service Provider's eYssen Cloud environment; (ii) the affected instance has no custom development or third-party module/configuration installed, and no intervention has occurred that might influence the bug; (iii) the bug is not caused by the failure/outage or change of an external provider (e.g., cloud, email, CDN, browser, network, database infrastructure), or by data quality or access rights settings; (iv) the bug is reproducible in the supported eYssen version and supported browsers; (v) the Client cooperates and provides the necessary information, samples, and accesses for reproduction. The fix will be carried out within a reasonable deadline according to professional priority. This commitment does not constitute a warranty or a basis for liquidated damages and does not cover performance tuning, new feature development, compliance with legal regulations, data migration, user error, external integrations, or third-party components; these constitute an hourly-rate assignment.
3.3. Assistants for Performance: The Service Provider is entitled to engage a subcontractor/assistant. The Service Provider ensures coordination, however, its liability for the third party’s fault is limited by Chapter 7.
3.4. Client Cooperation: The Client is obliged to provide the necessary information, accesses, decisions, and testing in a timely manner. Delays, additional work, and costs arising from these shall be borne by the Client.
3.5. eYssen Cloud and Backups: The eYssen Cloud operates on the platform of the (current infrastructure provider); backups may be stored in a separate location. The Service Provider is not responsible for consequences arising from faults, outages, or changes by external providers (infrastructure/backup) (see Chapter 7). Regular restoration testing is performed by the Service Provider only upon separate order.
3.6. Client Data Protection and Backup: The Client may arrange for supplementary security backups and data protection measures within its own scope of interest. The Service Provider excludes its liability for damages arising from the lack of own backups.
3.7. Risk of Community Components and Updates. Due to the community nature of the ERP ecosystem and eYssen, the behaviour of third-party components, modules, and updates cannot be guaranteed in advance. The Service Provider provides no guarantee regarding their compatibility, future operation, or bugs or performance changes arising from them; in such cases, intervention and troubleshooting are carried out on an hourly-rate basis.
3.8. Definition of Reaction Time. “Maximum Reaction Time” refers to the start of processing the reported task/bug (first substantive feedback, triage, initiation of reproduction), and does not imply the deadline for the final solution or closure. The resolution time is always case-by-case, influenced by the nature of the bug, its complexity, reproducibility, dependencies, and the cooperation of external providers. A responsible resolution deadline cannot be guaranteed without prior, precise knowledge of the nature and circumstances of the bug; some cases can be remedied within minutes, others within days, or even longer in the case of third-party dependencies.
3.9. Service Interruption and Maintenance. The Service Provider is entitled to hold scheduled maintenance (preferably during low-traffic periods), which may result in temporary unavailability. In the event of urgent troubleshooting, extraordinary maintenance may be held without prior notice. Maintenance periods do not constitute a breach of contract.
3.10. Start of Reaction Time and Reporting Channel. The calculation of the “Maximum Reaction Time” starts from the moment the report is received on the Service Provider’s official support channel ([email protected], the client-specific {client-shortname}@eyssen.com, or the ticketing system available on https://www.eyssen.com). The Business Days and operating hours defined in Section 1.6 shall govern the measurement of reaction time. A report made through an unofficial channel (e.g., personal message, personal email address of our colleagues) is only considered received if the Service Provider has recorded and acknowledged it on the official channel.
4. Remuneration
4.1. Prepaid Balance: The use of services is subject to a prepaid balance. The Service Provider deducts from this balance for the tasks according to the current price list (in commenced billing units).
4.2. Balance Exhaustion: In case of zero or negative balance, the Service Provider is entitled to suspend work and/or access until a new top-up is made.
4.3. Usability and Expiry of Prepaid Balances. The prepaid balances paid in advance by the Client may be used for 12 (twelve) months from the date of the order. After this period, the unused balance shall expire and is non-refundable (in accordance with Section 4.6). Billing shall follow the “First-In, First-Out” (FIFO) principle.
4.4. Price Change: The Service Provider is entitled to modify the prices; the change shall apply to orders and top-ups due after publication. The already topped-up balance is not affected retrospectively by the modification.
4.5. Applicability of Price Change – 1-Year Protection. Notwithstanding Section 4.4, if the Client established the service relationship within 1 year (GTC acceptance + first prepaid top-up or individual agreement), the Service Provider’s general fee modifications shall only apply to the Client after the expiry of the 1-year period. The price change does not affect already topped-up balances retrospectively.
4.6. Refund: The prepaid balance is not refundable as a general rule. The parties may agree on an exception in writing.
4.7. Currency and VAT (Value Added Tax): The prices are net prices in EUR; VAT will be charged according to the applicable laws.
4.8. Junior Consultant Fee (30% Discount). The Service Provider may provide a Junior Consultant (trainee/assistant role, lower hourly rate, with a 30% discount applied to the billed time) depending on the nature of the task. The involvement of a Junior is always under professional supervision; the details of the discount and the conditions for their involvement are specified in the current price list (Appendix M2). The time worked by the Junior is accounted for separately in favour of the Client.
4.9. Immediate Assistance / Express Surcharge (50% Surcharge). At the Client’s request, the Service Provider may undertake immediate, out-of-turn intervention (Express). An Express request automatically incurs a 50% surcharge (the express surcharge according to the current price list shall be applied) and can only be guaranteed if there is free capacity. The fulfilment of an Express request does not constitute an SLA commitment; it only ensures an urgent start, and the resolution time remains case-by-case.
4.10. The Service Provider may commence the task at its own discretion after confirming the order, however, it is entitled to condition the start of work on the financial crediting of the amount specified in the pro-forma invoice. In the case of currency transfer (e.g., SWIFT), it is the Client's responsibility to provide the necessary data for identification (reference, pro-forma invoice identifier).
4.11. Currency Difference and Exchange Rate. If the Client pays in a currency different from the one on the invoice, the amount credited is determined by the actual conversion exchange rate and – if applicable – the conversion fee applied by the Service Provider’s bank or settlement partner on the day of crediting. The prepaid balance will be credited with the net amount actually credited after conversion. All banking, intermediary banking, and payment transaction costs associated with the payment shall be borne by the Client. In the event of a deficit arising from exchange rate and cost differences, the Service Provider is entitled to request the replenishment of the difference; in the case of overpayment, the surplus increases the Client's prepaid balance. The exchange rate (e.g., Bank of England) applied in the Service Provider’s accounting – according to law – may differ and serves only for accounting purposes. The Service Provider reserves the right to accept payment only in the currency of the invoice for certain transactions.
5. Subscription and Payment Terms
5.1. The Service Provider issues an electronic invoice for every top-up and/or performance, with a payment deadline of 8 days from issuance.
5.2. Legal Consequences of Late Payment – Late Payment Interest and Compensation for Recovery Costs (B2B). a) Late Payment Interest. In the event of the Client's payment default, the Service Provider is entitled to claim statutory interest on the overdue debt under the Late Payment of Commercial Debts (Interest) Act 1998. The rate of statutory interest is currently 8% plus the Bank of England base rate. The interest accrues from the day after the due date until the debt is paid. b) Compensation for Recovery Costs (B2B). In the case of late payment between businesses, the Client is obliged to pay a fixed sum to cover the Service Provider's debt recovery costs, as stipulated by the Late Payment of Commercial Debts Regulations 2013. The amount of this compensation is currently £40, £70, or £100, depending on the size of the debt. c) The Service Provider is entitled to recover all reasonable costs incurred in the collection of overdue amounts, including legal fees and disbursements.
5.3. On-site Visit, Travel Time, Equipment or Licence Costs shall be billed separately, subject to prior agreement.
5.4. Payment Methods (Bank Transfer or Card). Invoices can be settled by bank transfer to the bank account/IBAN specified on the invoice, or by online card payment through the Service Provider’s contracted payment service provider (3-D Secure authentication is supported). For transfers, the invoice number must be included in the reference section; UK Faster Payments, BACS, CHAPS, and SEPA transfers are accepted. For card payments, the time of crediting is the confirmation by the payment service provider. In case of currency difference, Section 4.11 shall apply. Cash payment is not possible. The Service Provider is entitled to restrict the payment method for certain transactions (e.g., bank transfer only for subsequent invoices). In the event of a chargeback or failed payment, the Service Provider may suspend the service and apply set-off against the existing balance.
5.5. VAT and Place of Supply Rules (UK Service Provider). As a Sole Trader established in the United Kingdom, the Service Provider must adhere to UK VAT laws for the place of supply of services. The rules are determined by the location and status of the Client.
5.6. UK Clients (B2B). For services provided to a UK VAT-registered or non-VAT-registered business Client established in the UK, UK VAT is generally charged at the standard rate, subject to the Service Provider's VAT registration status in the UK.
5.7. EU Clients (B2B). For services provided to a business Client established in an EU Member State who provides a valid VAT identification number, the place of supply is generally the EU Client’s country (B2B ‘General Rule’). The service is outside the scope of UK VAT, and the Client is generally required to account for VAT in their own Member State using the Reverse Charge mechanism. The invoice will state the Client’s EU VAT number and the designation “Reverse Charge: The customer must account for VAT.”
5.8. Non-EU/Non-UK Clients (Third Country B2B). For services provided to a business Client established outside the UK and EU, the place of supply is generally the country where the Client is established. The service is outside the scope of UK VAT, and the invoice will not include UK VAT. The Client is liable for any local tax obligations (self-assessment in their own state).
5.9. EFTA/EEA/Non-UK Transfers and Intermediary Bank Charges. All banking, intermediary banking, and payment transaction fees associated with the payment shall be borne by the Client. The amount credited to the Service Provider’s account shall be considered the net amount of the top-up; the prepaid balance is increased accordingly.
6. Term and Termination of the Contract
6.1. The legal relationship between the parties is established by the Client’s acceptance of the GTC and/or prepaid top-up, for an indefinite period.
6.2. Either party is entitled to terminate the legal relationship with a 30-day notice period. Fees for work already performed and services used are due.
6.3. Immediate termination may be applied in case of a serious breach of contract.
6.4. In the absence of a separate written provision, these GTC shall supersede previous agreements on the same subject matter.
7. Rules of Liability
7.1. Direct Damages: The Service Provider is liable according to the general rules under English Common Law, but its total liability shall not exceed the amount of fees paid to the Service Provider in the 12 months preceding the eventcausing the damage.
7.2. Exclusion of Consequential Damages: The Service Provider is not liable for indirect or consequential losses (e.g., loss of profit, damage to business reputation, incidental damage arising from loss of data or content).
7.3. External Providers: The Service Provider assumes no liability for the performance, fault, or updates of infrastructure, licence, and backup providers (e.g., cloud, hosting, Odoo / Odoo Enterprise, version control, email, CDN, etc.).
7.4. Legal Compliance: It is the Client's responsibility to ensure compliance with the legal regulations applicable to its own activity (regulations, industry standards); the Service Provider provides no guarantee to the contrary.
7.5. The limitations of liability shall not apply in cases of fraudulent misrepresentation, deliberate default, or gross negligence causing death or personal injury, in accordance with applicable English law.
8. Confidentiality, Data Processing
8.1. The parties mutually acknowledge that the entire content of this contract and, even after its termination, all facts, circumstances, information, business data related to this contract, within the framework of the relevant laws, qualify as business secrets and are thus confidential. The party under the obligation of confidentiality may only be exempted from this obligation based on the other contracting party's prior written consent, in which the other contracting party precisely designates the scope of the secret that may be disclosed. Without the other party’s prior written consent, neither party may directly or indirectly disclose the essence of the relationship, the content of this contract, or any data and information that came to its knowledge to a third party. This obligation shall remain in effect during the term of this contract and after its termination.
8.2. The parties undertake to treat as business secrets the information that comes to their knowledge about the other party's organisation, procedures, and affairs during the performance of this contract. The rights to all information, data, business and legal solutions, and intellectual property handed over by the parties to each other concerning this contract shall remain with the parties, and the parties are not entitled to dispose of them in any way outside the scope of this contract. If the parties become aware of a new concept, solution, knowledge, or data during the performance of this contract, they are not entitled to use or publish it without the other party's prior written consent.
8.3. The parties mutually undertake regarding data and information originating from the other party:
- to take all reasonable steps to ensure their secure custody and storage;
- not to use them for any purpose other than that for which they were intended;
- to hold them only as long as necessary for the performance of their contractual obligations, after which they shall immediately return them to the other party, including all copies made by them, or destroy them with the other party’s prior written consent;
- to fully cooperate with each other during any inspection carried out by the party providing the data regarding the secure custody and use of the data.
8.4. The obligation of confidentiality does not extend to information that:
- Lawfully came to the party’s knowledge from a third person, independently of the other party, without an obligation of confidentiality;
- Has already been made public with the other party's written permission;
- Contains general ideas, concepts, knowledge, and techniques;
- Falls within the scope of official data provision obligations.
8.5. The parties may only use the information and data that came into their possession in connection with this contract for the purpose of performing this contract, and may only process it for this purpose, in accordance with the relevant data protection laws, particularly the GDPR and the Data Protection Act 2018 (UK), for the purpose of contract performance and fulfilling legal obligations. The parties are obliged to delete all personal data from their records after the purpose of data processing ceases. The Service Provider’s detailed data processing policy is available on its website.
8.6. The processing of personal data is carried out according to the Service Provider’s currently effective Privacy Policy / Data Processing Notice, which is available on the Service Provider’s website. These GTC do not repeat the data processing terms. If the Service Provider processes personal data on behalf of the Client (as a Data Processor), the parties shall conclude a separate Data Processing Agreement (DPA) if necessary, in compliance with Article 28 of the GDPR.
8.7. Data Storage and Transfer. The eYssen Cloud is operated by default in EU/EEA data centres. In case of data transfer outside the EU/EEA, the Service Provider shall ensure appropriate safeguards (e.g., Standard Contractual Clauses (SCCs) or the UK International Data Transfer Agreement (IDTA)) are in place.
8.8. Account and Access Security. The distribution of user permissions, adherence to password rules, and the protection of API keys and admin accesses are the Client's responsibility. The Service Provider is not liable for damages resulting from unauthorised access, unless it is directly attributable to the Service Provider’s proven negligence.
9. Miscellaneous Provisions
9.1. GTC Modification: The Service Provider is entitled to unilaterally modify the GTC and the price list; the modification is effective from the date of publication. The Client accepts the modification by continuing to use the service; in case of disagreement, the Client is entitled to terminate the contract with a 30-day notice period.
9.2. Marketing and Reference: The Service Provider is entitled to use the Client’s name/logo as a reference, unless the Client prohibits this in writing.
9.3. Partial Invalidity: The invalidity of any provision of the GTC shall not affect the remaining provisions.
9.4. Governing Law and Jurisdiction: These GTC shall be governed by the laws of England and Wales. The parties shall primarily settle disputes through consultation; failing this, the courts of England and Wales shall have exclusive jurisdiction.
9.5. Acceptable Use and Suspension. Unlawful content, spamming, attempts at unauthorised access, excessive resource loading (e.g., crypto mining, DDoS), and running malicious code are prohibited. In case of serious or repeated breach, the Service Provider is entitled to immediately suspend the service and notify the Client of the incident.
9.6. Assignment: Assignment of contractual rights is only possible with the prior written consent of the other party.
9.7. Governing Language. These GTC and its appendices are prepared in English. Any foreign language translation is for informational purposes only; in case of discrepancy or dispute over interpretation, the English text shall prevail.
9.8. Jurisdiction (Non-Exclusive) / Arbitration Option. Notwithstanding Section 9.4, the Service Provider is also entitled to approach the court of the Client's registered office (non-exclusive jurisdiction). In the case of high-value disputes, the parties may separately agree in writing on arbitration proceedings (e.g., London Court of International Arbitration (LCIA) / ICC).
9.9. Anti-Corruption and Sanctions Compliance. The parties declare that they comply with the applicable anti-corruption, anti-money laundering, and sanctions (EU/UK/US) regulations. Serious violation is a ground for immediate termination.
9.10. Entire Agreement. These GTC and their appendices, along with any individual agreements, together constitute the parties’ entire agreement and supersede all prior statements, offers, or agreements on the same subject matter.
9.11. Set-off and Withholding. The Client is not entitled to withhold its payment obligations towards the Service Provider and is only entitled to set off with a claim that has been legally established or acknowledged by the Service Provider in writing.
10. Intellectual Property and Usage Rights
10.1. Basic Rights and Usage Licence. The copyright in the code, documentation, configuration template, procedure description, and know-how (collectively: "Work") created by the Service Provider during hourly work generally belongs to the Service Provider. Upon settlement of the invoice, the Client receives a non-exclusive, non-transferable, time and territorially unlimited usage licence for the internal business use of the Work within its own environment.
10.2. Feedback into eYssen Source Code and Open Source Publication (LGPL). The Client acknowledges that the Service Provider may incorporate generalisable solutions (e.g., bug fixes, modules, tools, code samples) created during tasks into the Service Provider's eYssen codebase and make them publicly available under the LGPL-3.0 licence, thus making them usable by anyone. The publication does not affect the Client’s business secrets, data, personal data, and specific configuration parameters; confidential information will not be included in the public code. Publication is the general rule; exceptions are governed by Section 10.3.
10.3. Exception – Special Business Logic / Client Ownership (Separate Agreement). If the task involves unique, commercially sensitive logic or a solution that constitutes a competitive advantage for the Client, the parties may agree in a separate written agreement (“Private Development Agreement”) that the ownership of the specific development belongs to the Client, and the code will not be included in the eYssen source code or made public. In such a case: a) the Service Provider retains all its background IP (general templates, tools, methodology, know-how), only licensing the necessary usage right for these; b) the open-source components used remain usable under their own licences (e.g., LGPL-3.0); the parties may not modify these licence terms; c) the separate agreement shall contain the terms for the transfer, maintenance, and support of the source code (repository access, transfer format, deployment, bug fixing).
10.4. Respect for Third-Party and Open Source Licences. The parties are obliged to comply with all applicable licence terms (especially: LGPL-3.0, and – if relevant – Odoo Enterprise licence). The Client acknowledges that LGPL may in some cases require making the source code of modifications available and preserving the licence/copyright notices; the Client is obliged to fulfil these requirements during its own use.
10.5. Background Rights and Know-How. The Service Provider’s existing components, development frameworks, scripts, and methodology (“Background IP”) remain the property of the Service Provider; the Client only receives a usage right for these to the extent necessary for the performance of the task. The agreement under Section 10.3 does not affect the ownership of the Background IP.
11. Force Majeure
11.1. Force Majeure. Neither party shall be liable for any delay or failure resulting from an unavoidable, unforeseen external cause (e.g., natural disaster, war, governmental restriction, national network failure). Obligations are suspended during the period of force majeure; if it persists for more than 30 days, either party is entitled to terminate the contract in writing without justification.
12. Notices
12.1. Notices. The primary channel for official communication between the parties is email; the Client shall receive notice at the address provided during the order, and the Service Provider at the address published on the website. An email shall be deemed delivered on the Business Day following its dispatch, unless the sender reliably proves otherwise.
13. Data Export and Offboarding
13.1. Data Export. Upon termination of the legal relationship, the Service Provider shall allow the Client to download/transfer its own data within a reasonable deadline and within the limits of technical possibilities. Data export and migration are hourly-rate tasks; the Service Provider is entitled to delete the Client’s data according to the backup schedule after 30 days, unless legal preservation is required.
14. Acceptance and Versioning (Click-Wrap)
14.1. GTC Acceptance and Versioning. For online orders, the Client accepts the currently effective GTC by ticking the “I accept the GTC” box; the Service Provider archives the fact of acceptance. For individual orders, the GTC is referenced in the email or order form.
14.2. Effective Date and Version. The effective date of these GTC is 1 January 2025. Version: UK-v1.0.
