Terms of Service

Version 2.0 - August 2026

Who These Terms Apply To

These Terms of Service ("Terms") regulate all access to and use of the TaxSync web-based software platform, including all associated modules, directories, rule engines, and application programming interfaces (collectively, the "Platform"), provided by TD Marvel d.o.o. ("TaxSync," "we," "us," or "Provider") to the subscribing organization ("Customer," "you," or "your").

Business Use Only

The Provider offers the Platform exclusively to businesses, legal entities under public law, and special funds under public law. By subscribing to or using the Platform, you represent and warrant that you are acting in a commercial or professional capacity.

Authority to Bind

If you accept these Terms on behalf of a company, organization, or other legal entity, you represent and warrant that you have the full legal authority to bind that entity to these Terms. If you do not have such authority, you may not accept these Terms or use the Platform.

How the Contract Is Formed

This agreement becomes legally binding when you:

• Register for a TaxSync user account;
• Access or use the Platform; or
• Complete a paid subscription purchase.

Whichever occurs first establishes the effective date of this agreement. Any conflicting or supplementary terms proposed by the Customer shall not become part of this contract.

Platform Delivery Model

TaxSync provides the Platform as a standard, multi-tenant cloud solution delivered on an "as-is" and "as-available" basis.

Right to Modify the Platform

TaxSync reserves the right, at its sole discretion, to continuously modify, upgrade, deprecate, or replace functionalities, interfaces, and rule engines of the Platform, provided such modifications do not materially defeat the primary purpose of the Customer's subscription.

Self-Service Operation

The Customer acknowledges that the Platform operates on a self-service basis. TaxSync assumes no obligation for successful implementation, customization, consulting, or specific outcomes resulting from the Customer's use of the Platform.

Ownership of Intellectual Property

All rights, title, and interest in and to the Platform, including its underlying code, algorithms, directories, rule engines, and user interfaces, remain the exclusive intellectual property of TD Marvel d.o.o. and its licensors.

License to Use

Subject to the timely payment of all applicable fees, TaxSync grants the Customer a limited, non-exclusive, non-transferable right to access and use the Platform solely for its internal business operations during the contract term.

Prohibited Uses

The Customer shall not, under any circumstances:

• (a) Copy, modify, translate, or create derivative works of the Platform;
• (b) Reverse engineer, decompile, disassemble, or otherwise attempt to derive the source code, algorithms, or architectural structure of the Platform;
• (c) License, sell, rent, lease, transfer, assign, distribute, host, outsource, or otherwise commercially exploit the Platform to third parties;
• (d) Employ automated systems, bots, spiders, scrapers, or other data mining technology to mass extract data, directories, or rule engines from the Platform;
• (e) Use the Platform in any manner that violates or encourages the violation of any applicable law, regulation, or the rights of any third party;
• (f) Use the Platform for any unlawful, fraudulent, abusive, defamatory, or harmful purpose;

• (i) Interfere with or disrupt the use of the Platform by any other customer or user;
• (j) Attempt to access or use the Platform through any means not intentionally made available or provided for by TaxSync; or
• (k) Circumvent, disable, or interfere with any technical restrictions or limitations of the Platform.

Account Security

The Customer is solely responsible for maintaining the strict confidentiality of all account credentials. TaxSync shall not be liable for any unauthorized access resulting from the Customer's failure to secure its credentials.

Data Responsibility

The Customer bears sole responsibility for the legality, accuracy, and quality of any data, materials, or packaging specifications uploaded into the Platform ("Customer Data").

Indemnification

The Customer agrees to indemnify and hold TaxSync harmless from all third-party claims, damages, and expenses arising from:

• Infringement of rights resulting from a violation of the Customer's obligations regarding Customer Data; or
• Unauthorized or improper use of account credentials if such use is attributable to the Customer.

Export Compliance and Sanctions

You represent and warrant that you (and the business you represent) are not located in, established in, or a resident of any country subject to applicable EU, US, or UN trade embargoes or sanctions. You further warrant that you are not listed on any restricted party or sanctions list. You agree to comply with all applicable export control laws in your use of the Platform.

Availability Commitment

TaxSync shall use commercially reasonable efforts to maintain the availability of the Platform. However, TaxSync explicitly disclaims any binding Service Level Agreements (SLAs), guaranteed uptime percentages, or guaranteed response times for standard subscriptions.

Enterprise Guarantees

If your organization requires binding SLAs, priority response times, or dedicated customer success channels, these are available exclusively through our Enterprise plans. Please contact our sales team to negotiate a separate agreement.

Maintenance and Suspension

TaxSync may temporarily restrict or suspend access to the Platform for maintenance, security updates, or capacity management without prior notice. Such suspension shall not constitute a breach of contract or trigger a right to fee reduction.

Error Correction and Data Remediation

5.4.1. TaxSync shall use commercially reasonable efforts to correct any bugs, errors, or defects in the Platform that materially affect its functionality or data accuracy, in a timeframe commensurate with the severity of the issue.

5.4.2. In the event of a Platform error resulting in incorrect data entry or processing, TaxSync shall:

• (a) Promptly take measures to eliminate the cause of the error;
• (b) Enable the Customer to correct any data that was incorrectly entered; and
• (c) Notify the Customer of the nature of the error and the measures taken.

5.4.3. The Customer is obligated to report any identified errors to TaxSync via email at support@taxsync-app.eu or through the in-platform support system, providing a detailed description of the issue.

Pricing and Charges

Usage fees are determined by the subscription plan or Pay-as-You-Go package selected by the user. All fees are non-refundable and exclusive of applicable value-added tax (VAT).

The Platform operates on a credit-based model:

• DoC Credits: each Declaration of Conformity (DoC) generation consumes one (1) DoC credit per unique combination of one (1) product, one (1) packaging type and one (1) country.
• Pay-as-You-Go: the Customer purchases a bundle of DoC credits in advance. Credits are valid for six (6) months from the date of purchase, as set out under Credit Expiry and Refund Policy below.
• Subscription Plans: the Customer receives a monthly allowance of DoC credits. Unused credits do not roll over to the next month. Additional credits may be purchased at the applicable rate if the monthly allowance is exceeded.

EPR (Extended Producer Responsibility) services, where subscribed, are billed separately as a recurring monthly fee. EPR fees are based on the number of reporting countries and the volume of active SKUs, as set out in the applicable pricing schedule.

Billing Methods

Fees are currently invoiced and paid via bank transfer. TaxSync will issue an invoice to the Customer at least 14 days before the start of each billing cycle. The Customer shall pay the invoiced amount by bank transfer to the bank account specified on the invoice.

Automatic card billing will become available in the future. Customers will be notified when this option is introduced.

Payment Terms

The following payment terms apply:

• Invoices are sent in electronic form (PDF) to the email address provided by the Customer.
• Payment is due within 14 calendar days from the invoice date.
• The Customer is responsible for ensuring that bank transfer fees are covered and that the full invoiced amount is received by TaxSync.

Suspension for Non-Payment

If the Customer defaults on any payment, TaxSync reserves the right, without incurring liability, to immediately suspend the Customer's access to the Platform until all outstanding amounts are paid in full.

Fee Adjustments

TaxSync reserves the right to adjust subscription fees or credit pricing. We will notify you of any price increases in text form (e.g., via email) at least 30 days before your next billing cycle begins.

Your options:

• If you do not object within 30 days, the new price will be deemed accepted and apply to your next billing cycle.
• If you object, the price change will not take effect, but TaxSync reserves the right to terminate your subscription at the end of your current paid term.

Credit Expiry and Refund Policy

DoC credits purchased under a Pay-as-You-Go plan are valid for six (6) months from the date of purchase. Any unused credits after this period will expire and cannot be refunded or reinstated.

Credits included in a Subscription plan are available only during the active subscription month and do not roll over to the next month.

All DoC credits, regardless of plan, are non-refundable once purchased.

EPR services (Extended Producer Responsibility) are billed as a monthly subscription. EPR fees paid are non-refundable, even if the Customer does not fully utilise the service during the billing period. If the Customer cancels the EPR subscription before the end of the period, there is no entitlement to a refund of any fees already paid.

Applicable Law

The following provisions apply strictly in accordance with applicable Serbian and EU law.

Exclusion of Strict Liability

Strict liability for defects existing at the time of contract formation is expressly excluded to the maximum extent permitted by law.

Unlimited Liability

TaxSync is fully liable for damages caused by intent or gross negligence, as well as for damages to life, body, or health.

Limited Liability for Simple Negligence

In cases of slight negligence, TaxSync shall only be liable for the breach of essential contractual obligations. In such cases, liability is strictly limited to the typical, foreseeable damage at the time the contract was concluded. TaxSync shall under no circumstances be liable for indirect damages or loss of profit.

Free Accounts

If you are accessing the Platform free of charge (e.g., via a trial or free account), TaxSync's liability is strictly limited to intent and gross negligence.

"AS-IS" and "AS-AVAILABLE" Basis

The Platform and all information, content, and materials available on or through the Platform are provided on an "as-is" and "as-available" basis. TaxSync does not warrant that the Platform will be error-free, uninterrupted, secure, or free of viruses or other harmful components. TaxSync does not warrant that any defects or errors in the Platform will be corrected.

To the maximum extent permitted by applicable law, TaxSync disclaims all warranties, whether express, implied, statutory, or otherwise, including but not limited to warranties of merchantability, fitness for a particular purpose, non-infringement, and any warranties arising out of course of dealing, usage, or trade practice.

TaxSync does not warrant or make any representations regarding the use or the results of the use of the Platform in terms of its correctness, accuracy, reliability, or otherwise. The Customer assumes the entire risk as to the quality and performance of the Platform and the accuracy and completeness of any information obtained through the Platform.

Confidentiality Obligation

TaxSync shall treat any packaging and business data provided by the Customer as confidential.

Exceptions

Information shall not be deemed confidential if it:

• Is or becomes generally known to the public;
• Was already known to TaxSync prior to disclosure;
• Is received from a third party without breach of an obligation; or
• Is independently developed by TaxSync.

Permitted Disclosures

TaxSync may disclose confidential information to its affiliates, employees, advisors, or to any official authority if legally required.

Data Usage for Platform Improvement

The Customer grants TaxSync the right to store and analyze all data generated during use of the Platform and to use it exclusively for:

• Operation and further development of the Platform; and
• Support purposes.

Data Processing Agreement

The processing of personal data on behalf of the Customer is exclusively governed by TaxSync's standard Data Processing Agreement (DPA). By accepting these Terms, the Customer legally executes and binds itself to the DPA, which forms an integral part of this agreement.

Subscription Duration

The contract commences upon successful account creation or checkout and remains in effect for the selected billing period (the "Initial Term"). Free accounts remain active until terminated by either party.

Automatic Renewal

The contract shall automatically renew for successive periods equal to the Initial Term unless either party terminates the agreement via the billing portal prior to the end of the current term.

Termination for Cause

The statutory right to extraordinary termination for good cause remains unaffected. Good cause for TaxSync includes:

• Material breach of the usage restrictions; or
• Payment default exceeding 30 days.

Post-Termination Data Deletion

Upon termination, the Customer's access to the Platform will be revoked, and TaxSync shall be entitled to delete Customer Data in accordance with its data retention policies.

Governing Law

This agreement and all disputes arising out of or in connection with it shall be governed exclusively by the laws of the Republic of Serbia, explicitly excluding the UN Convention on Contracts for the International Sale of Goods (CISG).

Jurisdiction

The exclusive place of jurisdiction for all disputes arising from or relating to this agreement is Belgrade, Serbia.

Updates to These Terms

TaxSync reserves the right to amend these Terms at any time. We will notify you of any material changes in text form (e.g., via email or in-app notification) at least 30 days before the changes take effect.

Your Right to Object

If you do not agree with the updated Terms, you have the right to object in text form within the 30-day notice period. If you do not object within this period, the updated Terms will be deemed accepted by you. We will specifically remind you of this consequence in our notification.

Effect of Objection

If you object to the changes, TaxSync reserves the right to terminate your subscription and account for cause. You also have the right to terminate your agreement for cause before the 30-day period expires.

Severability

Should any provision of this Contract be or become invalid in whole or in part, the other provisions shall remain in force. The invalid provision shall be deemed substituted by a valid provision which accomplishes, as far as legally possible, the economic purposes of the invalid provision.

12.1. Definition

Neither Party shall be liable for any failure or delay in the performance of its obligations under this Agreement if such failure or delay is caused by circumstances beyond its reasonable control, including but not limited to acts of God, natural disasters, war, terrorism, civil unrest, pandemics, epidemics, strikes, lockouts, acts of government or regulatory authorities, failure of internet service providers, power outages, or any other event that could not reasonably have been foreseen or prevented by the affected Party.

12.2. Notification and Suspension

The affected Party shall notify the other Party in writing of the occurrence of a Force Majeure event without undue delay. The obligations of the Parties shall be suspended for the duration of the Force Majeure event.
