Using Shopify can be a great option for setting up and managing an ecommerce website. It offers a user-friendly interface, a wide range of customizable themes, and integrates with various payment gateways. It also provides features like inventory management, order fulfillment, and analytics to help streamline your online business.

Here are a few reasons why you might not want to use Shopify:

1. Limited customization: While there are many themes available, the customization options might not meet all of your specific needs. If you require extensive customizations, you may need to hire a developer or consider a different platform.

2. Monthly fees: Shopify charges a monthly subscription fee, which may not be ideal for businesses just starting out or with limited budgets.

3. Transaction fees: In addition to the monthly fees, Shopify also charges transaction fees on each sale made through their platform. These fees can add up, especially if you have a high volume of sales.

4. Platform lock-in: If you decide to switch to a different ecommerce platform in the future, it can be challenging to migrate your website and data from Shopify to another platform.

5. Compliance with regulations: If you are in a highly regulated industry, such as the CBD or marijuana industry, you may face restrictions and limitations when using Shopify. It’s essential to ensure that the platform you choose is compliant with industry regulations.

Overall, Shopify is a popular and reliable ecommerce platform with many advantages. However, it’s important to consider your specific needs, budget, and industry regulations before deciding whether or not to use Shopify for your online store.
