a/o meaning in Business ?

Answer: What is and/or mean?

And/or (sometimes written and or) is a grammatical conjunction used to indicate that one or more or all of the cases it connects may occur. It is used as an inclusive or (as in logic and mathematics), while saying "or" in spoken language, or writing "or", might be inclusive or exclusive.

The construction has been used in official, legal and business documents since the mid-19th century, and evidence of broader use appears in the 20th century. It has been criticized as both ugly in style and ambiguous in legal documents.
