Clay • B2B Wholesale Pricing

Very straightforward and easy to use - I haven't tested functionality at time of writing because my store is not live, but feels smooth and bug-free from what I have found.

Their support/technical team customised signup form so it matches my theme style which is excellent.

The free app does not have a watermark which is excellent unlike other free app versions I have come across.

I would look no further than this for B2B wholesale in Shopify.
