How to say "vendor" in Japanese

• 売り手うりてCommon
  nounCovers the party selling something in a transaction, as opposed to the buyer. The natural choice when 'vendor' simply means 'seller', in everyday commerce or trade contexts.

  After considerable argument, the buyer and the seller finally came to terms.
• 売り主うりぬしCommon
  nounAlso means the seller in a sale, but is especially the contracted seller of property or goods, as in real-estate dealings. Use it when 'vendor' appears in legal or contractual settings.
• 業者ぎょうしゃJLPT N1approx.Common
  nounFits 'vendor' in the sense of a company or business that supplies goods or services, such as an IT vendor. Note that its core meaning is 'trader, dealer, businessperson, company', not 'seller' specifically.

  They're some developers who aim to make a fast buck!
• 売り子うりこCommon
  nounRefers to a person who actually sells — a shop assistant, hawker or peddler. It is not the usual word for 'vendor' as a seller party or supplying company; use it only for the person doing the selling at a shop or stall.
  今日きょう、野球やきゅうの試合しあいを見みに行いくと、売り子うりこがお湯ゆの入はいったタンクを持もって、そこいらを歩き回あるきまわっている。↗

Use 「売り手」 or 「売り主」 for the seller in a transaction (「売り主」 especially in real-estate contracts), 業者 for a vendor as a supplying business or dealer, and 「売り子」 for a person who sells at a shop or stall.
