I believe the answer is:
supplier
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">provider</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I know that provider can be written as supplier)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for supplier that I've seen before include "One who provides" , "Wholesaler, e.g." , "Provider (of goods)" , "Provider of a product" , "One providing something" .)
