Shopify or Squarespace app?

Hi - I searched for ‘Shopify’ and ‘Squarespace’ on this forum and only found 1 hit, which suggested:

setting up your shop on a platform like Shopify or Squarespace and then connecting to our API for file exporting and ordering

What I’m really looking for is something like ■■■■■■■■■ offers… ‘Automatic, on-demand order processing and fulfillment’

Anything like that from i.materialise?
