    1. The Service Provider warrants that all the services provided by them are operational from the date of entry into force of the legal relationship.
    2. The Service Provider will use all reasonable efforts to ensure the efficiency and continuity of the service, but shall not be liable for any loss or damage of any kind caused by the failure of the services. The Customer acknowledges that in exceptional cases the continuous operation of the service may be interrupted despite the prior knowledge and intention of the Service Provider. In such cases, the Service Provider shall make all reasonable efforts to provide the service as soon as possible. The Service Provider will make all reasonable efforts to ensure that the e-invoice service and its website are available twenty-four hours a day, seven days a week, all year.

The foregoing warranty shall not apply in the event that the failure of the service and/or the linked website is caused by the malfunction of the software or hardware of third-party suppliers, in which case the Service Provider shall limit their liability to the extent that such third-party suppliers have limited their own liability towards the Service Provider.
    3. The availability value is calculated on the basis of the Service Provider's statistics. The basis for the calculation of the statistics is the total time elapsed between the dates of the error reports received by the Service Provider and the time of the rectification of the errors, provided that the errors occurred within the control of the Service Provider. Availability is calculated as the percentage of the total time in error during the year, for the total number of customers.
    4. When calculating availability, the periods should not be taken into account when the e-invoice service is unavailable due to
      1. reasons within the Customer's control;
      2. force majeure;
      3. any other cause beyond the control of the Service Provider (in particular weather conditions, accident, fire, severe power supply disruptions, damage, theft);
      4. maintenance announced in advance.
    5. The Service Provider reserves the right to improve or modify the e-invoice service and/or the related website from time to time as necessary, provided that such modifications do not change the nature and functionality of the einvoice service in a manner that is contrary to the terms of this Agreement.

The Service Provider shall inform the Customer and the Invoice issuer after their logging into the e-invoice service about the planned downtime at least 3 (three) calendar days in advance.
    6. The Service Provider shall only be liable for damages caused by intentional or grossly negligent errors attributable to them. The limitation of liability is provided for in view of the fact that the use of the e-invoice service is free of charge for the Customer.
    7. The Service Provider shall check the invoice data received from the Invoice issuer or the electronic invoice generated in electronic format (xml) only from the aspect of whether they are in the format required by law, including whether the possibility of displaying the data content possible under the applicable law is ensured.
    8. The Service Provider shall not be liable in any respect for any actual material or immaterial damage or loss of profit suffered by the Customer as a result of the Invoice issuer providing incorrect data or failing to comply with their reporting obligations. The Service Provider shall also exclude their liability for any actual material or immaterial damage or loss of profit suffered by the Customer as a result of the conduct, wrongful act or omission of the account-keeping bank. Payment deadlines are the sole responsibility of the Customer, subject to bank lead times. The Service Provider expressly excludes any liability for late payment of invoices. The Service Provider shall not be liable for any damages resulting from the failure of informing the Invoice issuers of any changes in the Customer's data
    9. In the event of war, insurrection, terrorist act, strike or movement not constituting a strike, embargo on imports or exports, accident, fire, blockade, flood, natural disaster, severe disruption of energy supply or other unforeseen and unavoidable impediment, which is beyond the control of the Customer or the Service Provider (force majeure), and either of them is unable to fulfil a contractual obligation, that person shall not be liable for any loss or damage arising as a result of such events.
    10. The Contracting Parties acknowledge that it is common practice in Hungary for outgoing invoices to be issued by accountants or auditors on the basis of a separate contract. The Service Provider consents to the Invoice issuer handing over the username and password issued for the e-invoice service provided by the Service Provider to their accountant or auditor, thereby granting access. The Invoice issuer shall be solely liable for any damages resulting from the issuance of invoices by third parties or the handing over of access to the e-invoice service to third parties.
