Nick here from Shopify.
This is definitely something you can do, but it would require an app to achieve it. You can add different suppliers to your store, but to have other vendors actually selling via your store you would need an app.
Shopify has a guide discussing adding new suppliers to your store which you can read more about here. But in the case that this is not what you were looking for, you can find some of the multi-vendor marketplace apps I like from the Shopify App Store below:
Can you let me know if either of the two options above would work for what you're looking for, please?
All the best, Nick
