How to describe a customer's business [closed]

Solution 1:

To me each of your sentences describes a slightly different retail business, and I can't tell you what is more relevant.

A client has a retail business consisting of lots of shops distributed all over the world.

The international business is purely a collection of shops.

A client has a retail business that includes lots of shops distributed all over the world.

That retail business has, in addition to lots of shops, also one or more other important aspects (not necessarily related to the exploitation of those shops). Those shops might even only be a minor aspect of the business.

A client has a retail business with lots of shops distributed all over the world.

Is in my opinion quite similar to your second sentence with a slight implication that the shops are a major part of the business.
