Both SMB and enterprise plans include custom theme development. This means that the theme for your store is developed and designed by the team at Square1 from scratch, and is unique to your business. The entrepreneur plan gives you access to over 100 free themes that you can choose from. The enterprise plan is designed for established businesses with requirements for dedicated infrastructure and support teams, and tools to manage large scale operations, such as those for multiple warehouses, large scale marketing, and more. Most businesses choose to work with our SMB plans.
