1. The store is closed until further notice due to renovation.2. The store is closed indefinitely due to management issues.
 be closed until further notice be closed indefinitely「暫停營業」意思是商店暫停營業，未來有可能再恢復營業，白話翻譯即可，be closed until further notice 是正統的英文說法。而 closed 通常指商家暫時關門，明天還會開門，除非有上下文表明指停止營業，如:J.C. Penney will close its store in Tampa Bay.This store is closed permanently.這些例句中的 close 表示關門大吉。
