Website for online sales of paintings and prints. The site was made on the basis of the popular CMS Wordpress + Elementor. The functionality of the site contains the standard functionality of an online store: an order basket, a choice of product options, the ability to make payment online - using credit cards (via a connected PayPal payment gateway). As a result of the development, the client received a convenient tool for online sales and completely ready-made proven tools for monitoring and optimizing the sales process and financial billing. The WPEC WordPress plugin was chosen as the basis for building the online store functionality. This plugin fully satisfied the client's requests for this project. In addition, a script was developed to transfer the entire product catalog from the previous version of the online store based on WooCommerce. The content transfer module worked successfully and all catalog items were transferred to the database of the new engine. Including prices, images and product attributes.
