New online store
Are you just starting out and don't have your own e-shop yet?
We build your Shopify store from the ground up: from choosing and customizing a theme to connecting payments, shipping and accounting, all the way to launch. Don't want to deal with the details? We also offer a turnkey store for the Czech market.
Online store migration
Do you already have your e-shop and want to move it to Shopify?
We migrate products, customers, orders and content from Shoptet, WooCommerce or PrestaShop. We redirect your old URLs so you don't lose your search rankings, and we switch the domain only once the new store is finished and tested.
Customization and maintenance
Do you want to improve your e-shop or do you need regular maintenance?
We customize your theme, add new features, speed up your store and take care of regular maintenance. You can use prepaid hours for the work, and we usually start on assigned tasks within 24 hours.
