Crossword Genius

However, vendor considered all possibilities (7,3)

Ross

I believe the answer is:

thought out

I'm a little stuck... Click here to teach me more about this clue!

'considered all possibilities' is the definition.
'thought-out' can be an answer for 'considered' (thesaurus). I'm unsure of the 'all possibilities' bit.

'however vendor' is the wordplay.
'however' becomes 'though' (synonyms).
'vendor' becomes 'tout' (tout is a kind of vendor).
'though'+'tout'='THOUGHT-OUT'

Can you help me to learn more?

(Another definition for thought out that I've seen is " Planned".)
