    • Directive 2006/112/EC of the Council on the common system of value-added tax (Article 138.1).
    • Regulation (EU) 910/2014 of the European Parliament and of the Council on electronic identification and trust services for electronic transactions in the internal market and repealing Directive 1999/93/EC (eIDAS Regulation). USAGE OF THE SERVICE

3.1. Utilization of the Service
The use of the Service is subject to the registration of a user account or an invoicing account (Business) and, in certain cases detailed below, payment of fees.

3.2. User Account Registration
3.2.1. During user registration, the User must provide their first and last name, email address, and a password meeting the current requirements specified by the Service Provider for logging into the user account. Additionally, the User is required to accept the provisions of this GTC and the Service Provider's Privacy Policy (for more information, see point 10.2), without which the registration into the Service is not possible. By providing the email address, the User declares that they have full control over the email address provided during user account registration. Given that the Service Provider has no means of verifying this circumstance, the Service Provider assumes no responsibility for any damages that may arise from it.
3.2.2. In addition to the above, the User has the option to register using their Facebook or Google account. In this case, the Service Provider automatically retrieves the User's name and email address from the external service account used for registration, to which the User expressly consents.
3.2.3. For account security, the Service Provider recommends that the User's password, beyond the above, be at least 8 characters long, not too generic (e.g., asdf1234), not identical to the email address provided during registration, and additionally, the Service Provider suggests including lowercase and uppercase letters, numbers, and special characters (e.g., !; ?; +) in the password.
3.2.4. The User is responsible for storing the email address and password required for logging into the user account and, simultaneously, the invoicing account in a manner that prevents unauthorized access. The User must promptly notify the Service Provider and change their password in the user account section if they detect unauthorized access to the user or the invoicing account of the User or the Company represented by them.
3.2.5. By registering, the User grants permission to the Service Provider to duplicate certain data uploaded by the User into the Service for the secure operation of the Service and to modify the uploaded or otherwise provided data to the extent necessary for the provision of the Service and to align the data format with the Service Provider's system.
3.2.6. By registering, the User acknowledges that, for the purpose of improving the quality of the Service, the Service Provider may retain certain data even after the deletion of the User's account in a way that cannot be traced back to the User or the company on whose behalf the User registered and used the Service.
3.2.7. The User is responsible for the authenticity, accuracy, and the right to dispose of the data provided during user account registration.
3.2.8. The User is obliged to promptly inform the Service Provider of any changes to the data provided during user account registration in a way that the User modifies the changed data in the user account. The User is responsible for any disadvantages resulting from the failure to record the changes and cannot make any claims against the Service Provider in this regard.
3.3. Invoicing Account (Business) Registration
3.3.1. According to the relevant legislation, the Service can only be used by taxpayers according to the VAT Act. Therefore, for the registration of an invoicing account associated with a specific Business, it is necessary for the User to register a Business that exists, is registered in the company register, individual entrepreneurs' register, or other register corresponding to the business form, and the registered business must have a valid tax number. If the legislation does not require registration, only the presence of a valid tax number is a registration condition.
3.3.2. After the user account registration according to point 3.2, to use the Service, the User must create an invoicing account for the Business they represent, i.e., register a Business (company; individual entrepreneur; tax-registered individual; other organization) or, if the User does not have the Account Owner authorization, connect to an already registered Business or its invoicing account according to the provisions of point 3.4.
3.3.3. If the User registers a new Business or a new invoicing account for an already registered Business, it is mandatory to provide the form of the Business, its name, tax number, registered address, and email address. If the User provides the tax number or name of the Business, the Service automatically fills in the additional data from the external business database based on the authentic company register, which the User can modify during the registration process. During the Business registration, the User can optionally provide additional information, but the provision of these data is not a condition for the registration of the invoicing account and can be provided later.
3.3.4. After invoicing account registration, the Service Provider sends a confirmation to the email address provided by the User, informing them about the details of the registration.
3.3.5. The User must immediately notify the Service Provider of any changes in the invoicing account (Business) registration data by modifying the data in the invoicing account settings. The User is responsible for any consequences arising from the failure to record the changes. If the User completed the account registration according to point 3.2 but is not entitled to register a Business or its invoicing account, and only wishes to exercise one of the rights specified in point 1.2 under a)-e) concerning a specific Business according to point 3.4, connecting to a registered Business's invoicing account is necessary.

3.4.Connecting to the Business or its billing account requires providing the business tax number or name. After this, the User can send a request to the Business Account Manager, who is authorized to approve the connection and assign the appropriate permissions to the User.

3.5. Account Settings
3.5.1. The Service Provider informs the User that during the registration process, only the most essential and necessary data for the User or the represented business's registration is requested. To ensure the Service functions according to the characteristics of the User's business, additional (such as tax and financial) data may be required. It is the User's obligation to provide and set these data accurately, and the Service Provider is not responsible for any consequences arising from the omission or incorrect recording of this information.

3.6. Demo and Test Billing Account
3.6.1. The Service Provider allows the User to try certain features of the Basic Service through a demo account without registration or through a test account after user and billing account registration.
3.6.2. In the demo account, as no separate closed user account is created for the User, they can test the Basic Service simultaneously with other users. Due to this, as other users testing the demo account can see the data provided by the User, the Service Provider recommends not entering real (especially personal) data during testing. However, the data created in the demo account is permanently and irreversibly deleted at the end of the day.
3.6.3. The User can exit the demo account by clicking on the exit icon on the Dashboard. If the User logs into the demo account again on the same day, the data provided in the demo account is still accessible until the end of the day.
3.6.4. To try the test account, the User needs to register a user account and billing account according to the provisions of points 3.2. and 3.3. above.
3.6.5. The Service Provider draws the User's attention to the fact that due to their nature, invoices and other documents issued through the demo or test accounts are not actually issued to the designated business as a partner. Therefore, these modes are not suitable for conducting real economic activities and fulfilling related legal obligations.

3.7. Subscription
3.7.1. The use of the basic functions of the Service, beyond registration according to points 3.2. and 3.3., is not tied to additional conditions such as payment. However, in this case, the User cannot access certain functions of the Service. After the registration according to points 3.2. and 3.3., the Service Provider automatically provides the Basic Service in the free 30-day trial subscription package for the User or the business represented by them.
3.7.2. To access certain functions of the Service that require payment, the User needs to subscribe. The User can subscribe to the paid functions of the Service in their user account. Regardless of the above, certain functions may incur additional fees beyond the subscription, especially for Integrated Services, where the User may initiate subscriptions or payments through the Integrated Service.
3.7.3. The User can find information about the various subscription packages on the Website under the "Packages and Prices" menu. The User can initiate the subscription by clicking the "Join" button under the subscription package containing the services they wish to use.
3.7.4. After clicking on the link to initiate subscription modification, the User can select the desired (modified) subscription package on the surface that appears. This includes whether to extend their current package with the elapsed duration of the previous subscription period, switch to a lower or higher package.
3.7.5. On the surface for selecting payment method and subscription time, the User can choose the duration of the subscription request, which can be a monthly, quarterly, semi-annual, or annual billing cycle, along with the payment method by marking the circle next to the corresponding time or payment method. Afterward, the User can select by clicking the link to initiate payment.
3.7.6. Following this, a summary surface appears where the User can review their order details. The User can modify individual order details by returning to the respective surfaces by clicking the link in the lower-left corner of the surfaces.
3.7.7. After checking the order details on the summary surface, the User can order the selected subscription package by clicking the "Finalize Order" link, which constitutes a contractual offer with payment obligations.
3.7.8. Detailed information about the subscription packages, their prices, and payment methods can be found in Chapter 7 of these Terms and Conditions.

3.8. Additional Conditions (Establishing a Data Connection with the Tax Authority - NAV)

3.8.1. In order for the User to effectively use the Basic Service, it is necessary for the billing account to be connected to the tax authority's online invoice system, establishing the mandatory data connection required by regulations for invoice data provision. The User can accomplish this after following the steps outlined in section 3.3.4 or at any time before issuing the first invoice, by taking the steps indicated in the "NAV Data Connection" card among user integrations. Without this connection, the documents issued by the User will not be transmitted to the online system of the tax authority (NAV).

4. Service Content
4.1. General Provisions
4.1.1. The Service Provider offers the services defined in this GTC with content specified in this GTC, other documentation related to the service, and on the Website. It is the responsibility of the User to familiarize themselves with all documentation related to the Service.
4.1.2. The Service Provider continuously develops the functions of the Service, and they may expand or cease. In case of the former, the Service Provider notifies the User in advance through email and/or posting on the Website, emphasizing that such changes do not constitute an amendment to this GTC.
4.1.3. The content of the Service and the functions available within the Service may depend on the User's subscription package and the rights defined in section 1.2. of this GTC.
4.1.4. The Service Provider draws the User's attention to the fact that information, suggestions, or findings published on the Website or on other pages operated in connection with the Service for the benefit of the Service Provider are excluded from liability regarding their accuracy and validity. Such information, conclusions, or findings, automatically generated in reports, do not, under any circumstances, constitute the opinion of the Service Provider, as they are deductions and factual statements derived from User data, and as such, they do not provide legal or tax advice.
4.1.6. The Service Provider reserves the right to provide the Service with individual terms and content for certain Users based on its unique decision. However, the Service Provider is not obliged to do so, and the User cannot demand it. Similarly, the User cannot demand that the Service Provider provides a service not specified in this GTC or other documentation related to the Service.
4.2. Online Invoicing Service (Basic Service)
4.2.1. Through the Basic Service, the Service Provider enables the User to issue invoices (hereinafter collectively referred to as "Invoice") on behalf of the represented Company that comply with the formal and substantive requirements prescribed by relevant legislation. The Service Provider also ensures the storage of the issued Invoices as per section 4.2.13 of this GTC, and their retrieval as per section 4.2.10 of this GTC.
4.2.2. The Basic Service comes with functions detailed in the accompanying User Manual and the Service's Knowledge Base. The Service Provider ensures the availability of the functions of the Basic Service that are included in the User's subscribed or ordered package.
4.2.3. The Service Provider emphasizes that through the Basic Service, it only provides a framework for issuing Invoices that comply with legal requirements. It is the User's responsibility to provide the content of the Invoices (buyer, item description, tax rate, etc.), and the Service Provider is not obliged to provide assistance in this regard. Consequently, the Service Provider fully excludes its responsibility for the content of the Invoice.

4.2.4. The Service Provider allows the issuance of the following types of Invoices:
    • Invoice
    • Proforma Invoice
    • Advance Invoice
    • Final Invoice (based on a Proforma or Advance Invoice)
    • Document falling under the same category as an Invoice – Credit Note
    • Delivery Note
The types of Invoices that can be issued in each subscription package may vary, and detailed information can be found on the Website under the "Packages and Prices" menu.
4.2.5. The Basic Service allows for the online creation of Invoices, which, however, are considered equivalent to paper-based Invoices. Additionally, electronic Invoices can be issued.
4.2.6. For the authenticity of online, computer-generated Invoices, it is necessary for the User to print them. In contrast, electronic Invoices retain their authenticity only in electronic form.
4.2.7. Within the Basic Service, the User has the option to send the issued Invoices to their partners via email, to one or more email addresses at the same time.
4.2.8. As part of data retrieval, the Service Provider ensures that the User can retrieve the Invoices issued through the Basic Service at any time, as long as the User has an active subscription with the Service Provider or as long as the represented Company has active billing accounts. The User can view the content and image of the Invoice and download (repeatedly) the Invoices.
4.2.9. Within the Basic Service, the Service Provider ensures compliance with legal requirements for content and data structure in data reporting to the state tax authority regarding Invoices issued through the Basic Service. This obligation applies to the extent that the User has established the data connection as per the provisions of section 3.6.1.
4.2.10. Regarding the retention of Invoices, the Service Provider commits to keeping them for up to 13 years from the date of issuance but not beyond the day when the User or the represented Company's active billing accounts cease to exist. However, as long as the User has an active registration or the represented Company has active billing accounts, the Invoices are retained.
4.2.11. In the event of termination or deletion of the registration or billing account for any reason not attributable to the Service Provider, the Service Provider no longer stores the Invoices issued in its system, and the retention period mentioned in section 4.2.10 is not applicable upon the termination of the legal relationship. Considering the above and since, according to relevant regulations, the obligation to retain Invoices rests with the issuer, and since the Service Provider, by the commitment in section 4.2.10, does not assume the legal obligation and responsibility for retention, it remains the User's responsibility to save the Invoices issued through the Basic Service before the termination of registration or deletion of the billing account. The Service Provider explicitly draws the User's attention to this before the registration or billing account is deleted.
4.3. Additional Services
4.3.1. The Service Provider offers the following Additional Services related to the Basic Service.

4.3.6.1. In the case of delegated invoicing, the User can issue invoices on behalf of another User's represented Company, provided that the other Company has authorized the User to do so. In this regard, the Service Provider recommends entering into a written contract between the User, the Company represented by them, and the contracting company.
4.3.6.2. Self-billing is a specific case of delegated invoicing when the User, on behalf of their represented Company's supplier, issues an Invoice to themselves, i.e., to the represented Company. In this case as well, the Service Provider recommends entering into a written contract.
4.5. Integrated Services
4.5.1. In addition to the Basic Service and Additional Service, the Service Provider offers Integrated Services built on them but operated by third-party service providers. These services are based on the Basic Service and the data connection established with the Service Provider's system, complementing it or providing additional features.

By registering and using the Service, the User acknowledges that there may be cases where they cannot access their account and use the Service.

However, the Service Provider is not responsible for the occurrence of such cases, even if it results in data loss or any damage to the User.

Instead, the Service Provider may offer the User the option to proceed with the correct and actual pricing. If the User does not choose to withdraw, the Service Provider will handle the User's paid fees in accordance with the provisions of Section 16.10.

Within 3 months following the termination of this GTC for any reason, the Service Provider permanently and irrevocably deletes the data transmitted to it, except for data that is still needed for statistical purposes. In this case, the Service Provider anonymizes the data or makes it unrecognizable in a way that it cannot be inferred to the User or any other third party. Before the final deletion of the data, the Service Provider offers the User the opportunity to save their data, documents, etc., stored in the Service. The Service Provider is not responsible for any consequences arising from the failure to do so.

12.18. The User is responsible for the accurate configuration of various access permissions assigned to third parties within the Service by the Account Holder and Users with Administrator privileges.

It is the User's responsibility to regularly check and review permission settings.
12.19. The Service Provider is not responsible for the content of invoices or other documents issued by the User through the use of the Basic Service.

12.20.

12.22. Considering that, in the case of invoices and other documents issued using the Service, the User is responsible, according to the relevant legal regulations, for preserving the documents for the period specified in the law, the Service Provider is not responsible if, due to any reason, the User fails to save the invoices related to the Business stored in the Service after the termination of the legal relationship according to these GTC, despite the Service Provider offering this possibility to the User before the termination of the Agreement.

fire, explosion, mass illness (epidemic),
government measures,
war, acts of war (regardless of whether a state of war exists or not),

general nationwide strike,
epidemiological measures, especially epidemiological measures such as curfews, bans, and any measures taken by either Party related to reducing personal contacts according to the recommendations of epidemiologists (suspension of tasks requiring personal presence). It does not constitute a breach of the contract if the performance of obligations is prevented or limited by a force majeure event. If a force majeure event occurs, the party becoming aware of it must immediately notify the other party in writing. In the event of a force majeure, the deadlines specified for the performance in the Contract may be extended by the time the parties are unable to perform due to the force majeure event. After the end of the force majeure event, the party in delay is obliged to perform the outstanding obligation as soon as possible to prevent further delay.
12.27. The Service Provider is obliged to inform Users without undue delay if there is an operational or security event or data protection incident within its scope of interest. If the User suffers damage due to the absence or delay of notification of an operational or security event or a data protection incident within the scope of interest, the Service Provider's liability for damages arises according to the Civil Code.

12.28. The User's responsibility for any infringement committed in connection with the use of the Service persists even after the termination of the legal relationship according to these GTC.

Furthermore, the Service Provider may terminate the contract with immediate effect and delete the User's account if the User uses insulting, offensive, or vulgar expressions about the Service Provider's employee, representative, or the Service Provider itself, either verbally or in writing, on any forum, or in connection with its qualification or activity.

16.9. The Service Provider is also entitled to terminate the legal relationship under this Agreement and delete the User's account if the User exhibits behavior that violates the provisions of this Terms of Service or any legal regulations, or abuses the use of the Service, especially if the User commits a criminal offense through the use of the Service.
