The main things people use here are:

G2 & Capterra for software

Clutch & GoodFirms for service providers and vendors

here i am referring to smaller businesses, so that they can checkout for localised businesses around them or their competitors

What kinds of businesses?

Accounting firms and design firms are mostly on Yelp, Google Reviews, or Clutch.

Office furniture firms are generally on Google Reviews and sometimes Yelp.

yeah they are but: for example - you own a bakery , you can log on to the site and check out what other bakery owners have bought and from where. for example someone bought a unique display rack or someone bought a cheaper billing paper roll.
