This guide sets out our service provider details as required by Law no. 6563 on the Regulation of Electronic Commerce and the Regulation on Service Providers and Intermediary Service Providers in Electronic Commerce; it explains the technical steps by which an order is concluded, how you can correct data entry errors, and how you can store and access the contract texts.

2. Purpose and scope of this guide
The guide has been prepared to make the process by which orders are concluded at https://www.opencartextra.com transparent, and to bring together in a single document the information obligations that legislation imposes on a service provider.
No physical goods are sold over the internet through our site. The payment surface serves to collect service fees from customers we serve or have agreed to serve, and the order steps are designed for that purpose.
This guide does not replace the Pre-Contractual Information Form or the Distance Sales Agreement; it complements them. In the event of a dispute, the Pre-Contractual Information Form and the Distance Sales Agreement you approved at the time of the order prevail.
3. Conclusion of an order: the technical steps
Step 1 — Order: you click the purchase button on a service page, the payment button on a proforma document sent to you, or a payment link. In this step you set the order items, the term or quantity, and any domain name selection. The amount is always recalculated on the server from the current catalogue and exchange rate; an amount sent from your browser is never taken into account.
Step 2 — Billing and contact details: you choose an individual or corporate invoice type and enter your name or company name, identity or tax number, tax office, e-mail, telephone and address. If you have given us details before, the fields arrive pre-filled; you can change all of them.
Step 3 — Summary and approvals: the order items, the net amount, VAT and the total including taxes, the exchange rate applied and its date, the seller details and a summary of the right of withdrawal are shown on a single screen. The Pre-Contractual Information Form, the Distance Sales Agreement and the Payment Processing Privacy Notice can be read in full in windows opened from that screen. The approval boxes are not pre-ticked.
Step 4 — Order confirmation: when you press the “Confirm order with obligation to pay” button the contract is concluded, and the date and time of approval, your IP address and the version numbers of the documents you approved are recorded. At that point your order is given a number and your proforma document is created.
Step 5 — Payment: the payment institution's 3D Secure enabled payment screen opens within the page. You enter your card details only into that screen; that data is never transmitted to our systems at any stage.
Step 6 — Outcome and confirmation: the outcome of the payment is determined by the notification sent from the payment institution to our server and verified cryptographically. Returning from the payment screen to our page does not by itself mean that payment has been completed; the result page waits for the verified notification and then shows you the status.
Step 7 — Delivery of the documents: once payment is verified, your proforma document stamped PAID, together with the Pre-Contractual Information Form and the Distance Sales Agreement filled in with your order details, is sent to your e-mail address without delay.
4. Information shown before payment details are entered
Legislation requires that the contract terms, including the total price payable, be shown clearly before payment details are entered. The summary screen shows: the order items and their characteristics, quantity or term, unit price, net amount, VAT rate and amount, total including taxes, the exchange rate applied and its date, the seller's legal name, address, tax and MERSİS numbers, the period of performance, a summary of the right of withdrawal and the address for a withdrawal notice.
The total amount is shown before the payment screen opens and again above the payment screen.
The Turkish lira amount on the summary screen is fixed for 30 minutes. If that period expires, the order is repriced at the current exchange rate and the new amount is submitted for your approval.
5. Facilities for correcting data entry errors
You can return to the previous step at any point in the order process. The “Edit details” link on the summary screen takes you back to the billing and contact step; to change the order items you can return to the order step.
Form fields report values that do not meet the input rules (an invalid e-mail address, a missing tax number, an incorrect postal code) immediately, through an explanatory message shown next to the field.
To change order details after the payment screen has opened you must close the payment screen and return to the summary step; in that case the current payment session is invalidated and a new order record is created.
If you notice an error in your invoicing details after payment has been completed, notify accounting@w3.net.tr and the invoice will be corrected to the extent permitted by the applicable legislation.
6. Confirmation of the order
Your order and payment are confirmed by electronic mail without delay. The confirmation e-mail contains the order number, the items, the amount, the payment method and the next step specific to the service.
If payment fails, an e-mail explaining the reason and allowing you to try again is sent; alternatively, bank transfer/EFT details are provided.
If you leave without completing the order, a single e-mail may be sent a short time later reminding you that your order is waiting. That e-mail is not a commercial electronic message but information about the order process.
If the confirmation e-mail does not arrive, please check your junk/spam folder and write to hello@w3.net.tr.
7. Storing the contract texts and accessing them
Under article 11 of the Distance Contracts Regulation, the pre-contractual information and the contract texts are delivered to you on a durable medium. That obligation is met by the PDF documents attached to the confirmation e-mail sent after payment.
If the PDF attachments cannot be produced for any reason, the e-mail is still sent and the full text of both documents, together with the version number and the record of approval, appears in the body of the e-mail. Your access to the documents is never obstructed.
The current versions of the documents are always available in the legal documents section at https://www.opencartextra.com, where you can read, print and store them.
The version you approved is retained together with your order record for ten years. If you write to hello@w3.net.tr quoting your order number, a copy of the document version you approved for that order is sent to you.
You can access your proforma document through a link specific to you, before and after payment, and download it as a PDF. Once payment is completed the same document is regenerated with a PAID stamp and serves as the payment receipt.
8. Language and version of the contract
The order process is offered in Turkish and in English. The contract is concluded in the language in which the order is placed and the documents are sent in that language.
If there is any discrepancy between the Turkish and English texts, the Turkish text prevails for buyers established in Türkiye.
Every document carries a version number and an effective date. The version of this guide is 1.0. Documents may be updated with prospective effect; the version approved at the time of an order applies to contracts already concluded.
9. Price, exchange rate and the price lock
List prices are published in US dollars, excluding VAT; collection is made in Turkish lira.
The foreign exchange selling rate of the Central Bank of the Republic of Türkiye at the time of the order is applied. The rate used, its date and its source are shown in the order summary and frozen into the transaction record.
Where current exchange rate information cannot be reached, purchasing is temporarily not opened and a warning is shown on screen; this is a deliberate choice to prevent collection at an incorrect rate.
Proforma documents are valid for seven days from their date of issue; the amount on the document does not change during that period.
10. Technical requirements
To complete the order process you need a current web browser with cookies and JavaScript enabled.
The payment screen opens as a frame (iframe) within the page; advertisement blockers or frame blocking extensions may prevent the payment screen from appearing.
You must have access to the telephone number registered with your bank for 3D Secure verification.
If you encounter a technical problem during an order, writing to hello@w3.net.tr with a screenshot, the order number and the time speeds up the resolution.
11. Commercial electronic messages
Informational e-mails about the order, payment, invoice, performance and support processes are not commercial electronic messages within the meaning of Law no. 6563 and are not subject to separate consent.
Messages containing campaigns and announcements are sent only if you tick the optional approval box on the order screen. That approval is not a condition of the order.
You can withdraw your approval free of charge through the link at the bottom of every message or by writing to hello@w3.net.tr. Approval and refusal records are also tracked on the Message Management System (İYS).
12. Complaints, contact and resolution methods
You may send any complaint or request to hello@w3.net.tr or call +90 532 476 9667. Our support channels operate Monday to Saturday, 09:00–22:00 (GMT+3).
Requests are logged and answered within one business day at the latest; the resolution process is followed up in writing.
The procedure in the Cancellation, Refund and Right of Withdrawal Policy applies to cancellation and refund requests.
Buyers who qualify as consumers may bring disputes before the District/Provincial Consumer Arbitration Committees or the Consumer Courts within the monetary thresholds updated each year by the Ministry of Trade.
13. Outages, errors and security situations
The order and payment surface may be closed temporarily because of planned maintenance or infrastructure work; in that case a notice is shown on screen and an alternative payment method is offered.
Technical errors occurring after a payment has been started are logged and scanned regularly through reconciliation checks; if a payment is found to have been collected but not applied to an order, either the service is provisioned or the amount is refunded within one business day at the latest.
Transactions suspected of fraud are not processed and any amount collected is refunded.
If you identify a security vulnerability or suspect misuse, please report it to hello@w3.net.tr.
