Translation guide
The English word 'supplier' refers to a person or company that provides goods or services. In Japanese, the most common and natural equivalent is 仕入れ先 (shiiresaki) for a business supplier of goods, or サプライヤー (sapuraiyā) as a loanword. The choice depends on context, formality, and the type of supply relationship.
