Creating a Shopify public app in 2023 involves various factors that influence its cost. Firstly, the complexity of the app's functionality plays a significant role. Apps with advanced features such as personalized product recommendations, AI integration, or complex payment gateways tend to be more costly to develop. Additionally, the design and user interface contribute to the cost, as a well-crafted and visually appealing app requires additional design expertise. Moreover, the integration of third-party APIs or services may incur additional expenses. The development team's expertise and hourly rates, project timeline, and the need for ongoing maintenance and updates also impact the overall cost of creating a Shopify public app in 2023.
