The short answer is no.
All of our websites are designed using WordPress as a general rule. This is because we feel this platform gives us the most flexibility & capacity for creative freedom.
If you feel very strongly about using a certain platform (ei. Wix, Squarespace) we may not be the best fit for you.
For E-Commerce Websites, we tend to use shopify. This is because it offers the best features for those selling a product online!
Feel free to chat with us if you have any more questions about this.
