Hi, new to m2 can anyone recommend any free useful extensions for a wholesale website. Preferably the extensions are from a reliable source /magento marketplace.

1-Size matrix per product for ordering in quantity/sizes

2-Ability to order items currently out of stock

3-Display SKU in catalog view

4-Hide prices for unregistered users

5-remove "out of stock" display in category and detail view

6-multi store , hide out of stock items on one store show them on the other

Hi @awesomecowboy 

For what type of feature you are looking? If only for price then you can use Magento Default Tier pricing feature.
https://docs.magento.com/m2/ce/user_guide/catalog/product-price-tier.html 

If any more feature you can check below extension.

magento2-multi-vendor-wholesale-extension.html 

You can check extension demo first before purchase.

I hope it will help you!
