“Working with Williams Commerce and their extensive platform experience gave Gill the flexibility to remain agnostic during discovery and requirements gathering. It became apparent early on that BigCommerce was the perfect ecommerce platform for Gill allowing us to build a solid foundation for future growth and not ever have to worry about site stability and upgrades. The ease of integrations, plethora of third party apps and support from both Williams and BigCommerce was extremely impressive.
