See business's beginning to yield high return (3)
I believe the answer is:
lob
'high return' is the definition.
(I've seen this in another clue)
'see business's beginning to' is the wordplay.
'see' becomes 'lo' ('lo' is an archaic exclamation meaning 'look!').
'beginning to' suggests taking the first letters.
The initial letter of 'business' is 'b'.
'lo'+'b'='LOB'
'yield' is the link.
(Other definitions for lob that I've seen before include "High shot" , "sky" , "Elevated shot" , "Propel in a high arc" , "Toss" .)
