Terms of sale for services

This page

This page sets out the terms of sale, payment and delivery for projects, services and digital products bought on castintech.com (websites, e-commerce, promotion and advertising, consulting, software and similar work).

The Managed WordPress service has its own contracts; this page does not apply to it.

Placing an order

Buying on the site works in these steps:

You choose whether you are buying as an individual (for personal needs) or as a business (for trade or professional purposes). Business buyers enter their invoicing details.
You see an order summary with the scope of the service, the total price including taxes, the payment plan and the work schedule.
Individual buyers are shown the pre-contract information form and the distance service contract on screen before paying. The main features of the service, the total price, the right of withdrawal and the cases where it does not apply are summarised again just before the payment step.
You confirm that you have read and accept these texts by ticking boxes that are not ticked in advance. The order cannot be placed without this confirmation.
The order button states clearly that placing the order means you will have to pay (“Confirm order and pay”).
You pay in the secure payment step on the site. Once the payment succeeds, your order is confirmed by e-mail and a copy of the pre-contract information form and the contract is sent to you.

Prices and taxes

The order summary and every payment step show the net amount, VAT and the total including taxes separately. The amount you pay is the total including taxes.

If you received a personal quote, the scope and price in that quote apply; VAT is added to prices quoted without VAT and the total is shown. No extra charge that is not in the order summary is asked for without your separate, explicit consent.

Payment

Payments are made only in the payment step on castintech.com, by debit or credit card. You enter your card details in the PayTR secure payment screen embedded in the page; Castintech does not see or keep your card details.

For projects, the payment plan is usually two steps: half of the price when you order and the rest on delivery. The remaining amount is paid on the site in a second payment step linked to the same order number. Monthly services are paid in advance at the start of each period. The plan that applies is shown in the order summary.

The amount of each payment step is fixed in the order record. The expected total, the amount paid and the balance are tracked in the order record and shared with you.

A payment counts as made when the payment institution’s notice of a successful transaction reaches us. An e-invoice is issued for every payment and sent by e-mail; a payment receipt is not an invoice.

Delivery and performance

The services sold are carried out online or on your own systems; nothing is shipped and there is no delivery charge.

Work starts once the first payment is received and the content, access and files the work needs have reached us. What will be delivered and the schedule are in the order summary or the quote, and match the times stated in our promotion.

Delivery is notified in writing by e-mail. If content or access we need arrives late, the schedule moves by the same amount of time.

If it turns out that we cannot do the work within the promised time, we tell you in writing. Cancellation and refund terms are on a separate page.

Individual buyers

As an individual buyer you can withdraw from the contract within 14 days of the day it is made, without giving a reason and without paying a penalty.

If you explicitly agree that work starts before this period ends, the right of withdrawal cannot be used for a service whose work has started. This agreement is asked for with a separate box; if you do not give it, work starts after the withdrawal period.

How to withdraw and how refunds are made is explained on the cancellation and refunds page.

Business buyers

Buyers purchasing for trade or professional purposes state this separately in the purchase step. For these purchases the order summary, any quote and this page apply together.

Cancellation and refund terms for business purchases are in the business buyers section of the cancellation and refunds page.

Complaints and disputes

You can send requests and complaints to [email protected], call +90 532 484 72 92 or write to the address on the contact page.

Individual buyers can apply to a consumer arbitration committee or to a consumer court in a dispute. Before filing a case at a consumer court, applying to a mediator is mandatory. For 2026, disputes worth less than 186,000 TL go to the consumer arbitration committee; this limit is reset every year. You can apply to the committee where you live or where the transaction took place.

For disputes arising from purchases made for commercial or professional purposes, the Istanbul Central (Caglayan) Courts and Enforcement Offices have jurisdiction.

Records

Order, confirmation and payment records, and the version of the text shown to you, are kept for as long as the law requires. You can reach your copy of the contract through the order confirmation e-mail.

Cancellation and refund terms, the privacy policy and the cookie policy are on separate pages.
