Q: Should Providers be Multi-Sources or Configurations in configurable product? I have a store where 


*

*showing catalog from my vendors I don't have actual inventory 

*end-customer is not aware of my vendors (so it is not multi-vendor store)

*currently, I am using the configurable product for all product info and simple-product(configration) that is linked to the configurable and has (cost, qty, price, and vendorID)


*configrations are auto-selected based on cost so the customer does not select which product from which vendor because he is not aware of my vendors



Today I found this (multi-source-inventory-in-magento-2.3)
https://www.mageplaza.com/kb/multi-source-inventory-in-magento-2.html
and now I am confused did I did the wrong implementation?
I read about it but I am still confused


*

*how MSI handles different costs from different sources?

*how to handle different selling prices?

A: Multi-source basically let you define sources and stocks for products.
Like, If you have SKU ABC you got different sources where that product actually stands. Total QTY of that product is 30 but for you 20 available in lets say in warehouse-A and 10 in warehouse-B 
With Multi source inventory you can define that differentiate qty based on warehouses. so while shipping that product you'll get an option to choose from where you're shipping and all this manage within Magento Cool Isn't it !?
Regarding showing vendors MSI doesn't provide that option for now.
For more information you can go through below wiki.

Magento MSI doesn't provide update prices based on sources you need to customize at your own risk :P
