Terms for the Development of an Online Store

Revision dated 16.09.2026

1. General provisions

1.1. This Appendix No. 8 (the “Appendix”) forms an integral part of the Public Agreement for website development and technical maintenance (the “Agreement”) and applies to online-store development services.

1.2. The relationship between the parties is also governed by the current Service Provision Regulations, the selected tariff description, the technical specification or free-form project description and other terms directly applicable to the specific order.

1.3. In the event of a conflict between the general provisions of the Agreement and the special provisions of this Appendix concerning development of an online store, this Appendix shall prevail.

1.4. The scope of services is determined by the tariff selected and paid for by the Customer that was in force when the order was placed.

2. Subject and online-store model

2.1. The Contractor develops an e-commerce website through which a buyer can select a product, add it to a cart, place an order and, where included in the project, make an online payment.

2.2. Depending on the tariff, the store may include product categories, product cards, variants and attributes, prices, cart, checkout, customer account, promo codes, discounts, delivery methods, payment systems, stock control, notifications and integrations.

2.3. The result is an online store ready for publication or already published within the paid tariff scope.

2.4. The Contractor provides technical implementation but is not the seller of the Customer’s goods, a payment institution, carrier, warehouse operator or tax adviser unless separately agreed.

3. Products, prices and catalogue data

3.1. The Customer provides product names, descriptions, images, prices, variants, sizes, colours, SKUs, availability, tax rates and other required data.

3.2. The Customer is responsible for the accuracy of product information, prices, discounts, tax settings and availability and for holding the necessary rights to submitted materials.

3.3. Product import from CSV, XLSX, XML, API or another source is performed only where included in the tariff or separately agreed and paid for.

3.4. If supplied data does not match the agreed structure, conversion, cleaning, field mapping or manual processing may be treated as additional work.

3.5. After handover, the Customer is responsible for keeping products, prices and stock current unless store administration has been ordered separately.

4. Cart, checkout and customer account

4.1. Cart and checkout logic is implemented according to the selected tariff and agreed purchase flow.

4.2. Checkout may include buyer details, delivery address, delivery method, payment method, comments, required consents and order confirmation.

4.3. Customer accounts, order history, saved addresses, wish lists, repeat ordering and other buyer functions are created only where included in the tariff or separately agreed.

4.4. The Customer determines mandatory buyer fields and legally required consents applicable to its sales model.

5. Online payments and payment providers

5.1. Online payments are processed through third-party banks, payment institutions, acquirers or payment gateways.

5.2. The Contractor connects only payment methods that are technically available, supported by the selected system and included in the paid project scope.

5.3. The Customer enters into agreements with payment providers, completes identification, supplies required documents and ensures activation of its merchant account unless otherwise agreed in writing.

5.4. The Contractor does not guarantee approval by a payment provider, authorisation of every payment, commission rates, payout times or uninterrupted operation of a third-party payment service.

5.5. If a payment provider changes its API, module, security requirements or access conditions after handover, any required adaptation is assessed separately.

6. Delivery, taxes and order processing

6.1. Delivery methods, zones, rates, free-delivery conditions and other parameters are configured using information supplied by the Customer.

6.2. Integration with couriers, parcel lockers or logistics systems is performed only where technical access exists and the integration is included in the tariff or separately paid for.

6.3. The Customer determines tax rates, VAT treatment, tax-inclusive or tax-exclusive prices and other fiscal settings. Standard website development does not include tax advice.

6.4. Order statuses, notifications and administrative workflows may be configured, but actual fulfilment, packing, dispatch, delivery, returns and customer service remain the Customer’s responsibility.

7. Stock, warehouse and external systems

7.1. Basic stock control may be implemented within the online-store system where included in the selected tariff.

7.2. Synchronisation with ERP, warehouse software, CRM, accounting systems, supplier databases, marketplaces or other external systems is a separate integration and depends on the relevant service’s API, data structure and access rules.

7.3. The Contractor is not responsible for incorrect stock, prices or statuses resulting from Customer data, external-system errors, synchronisation delays or third-party outages.

7.4. Multi-warehouse logic, product reservation, advanced pricing, supplier feeds and other extended automation are developed only within the tariff or after separate agreement.

8. Legal materials, testing and changes

8.1. The Customer supplies its sales terms, delivery and return information, seller details, privacy information, cookie information and other legal materials required specifically for its store unless preparation of such materials is ordered separately.

8.2. Before handover, the agreed core scenarios are tested, including product display, cart, checkout, notifications and connected payment and delivery integrations.

8.3. Correction of the Contractor’s technical errors and bringing agreed functionality into conformity with the requirements is not an additional service.

8.4. New payment methods, delivery services, subscriptions, bonus or loyalty systems, advanced discount rules, additional currencies, marketplace integrations or other previously unagreed functions are additional work.

9. Price, support and further development

9.1. The development price is determined by the selected tariff and additional features selected by the Customer.

9.2. If the work actually required is less than the paid scope and the actual project price is objectively lower than the amount paid, the difference is refunded to the Customer.

9.3. Work beyond the paid tariff is performed only after price, scope and conditions are agreed. No paid additional work is performed without prior approval.

9.4. Paid licences, payment-provider fees, delivery services, external APIs, SaaS services, extra server resources and other third-party services not included in the tariff are paid separately.

9.5. Technical support included in the tariff covers correct operation of functionality developed by the Contractor within the paid scope and does not include ongoing store management, order processing, updating products, prices or stock, or development of new functions.

9.6. Delivery and acceptance are carried out under the Agreement. Requests for new functions, integrations, payment methods, delivery services or changes to business logic are not defects in completed work.

9.7. Matters not specifically regulated by this Appendix are governed by the Agreement, the Service Provision Regulations and other documents applicable to the order.
