Should I use Shopify or Squarespace for my DTC e-commerce site, particularly for fulfillment and shipping integration?

Members strongly recommend **Shopify** over Squarespace for DTC e-commerce, especially if you plan to scale or integrate with fulfillment partners.

- **Shopify** — described as the clear winner for fulfillment integration. Members report it works smoothly with shipping apps and third-party fulfillment providers, and is essential if you want a sustainable DTC business longer-term. - **Squarespace** — flagged as problematic for integration. Members operating fulfillment services for multiple brands report that Squarespace websites are "a nightmare" to integrate with shipping tools and apps, making it unsuitable if you need any fulfillment flexibility.

If you're running your own fulfillment or working with a 3PL, Shopify's app ecosystem and native integrations will save significant time and headaches. Squarespace's limitations become a real constraint as your business grows.
