When should you use "업체" and when should you use "회사"? How to use them appropriately?

Hello! It's been about a year and a half since I came to Korea. I am currently preparing for the TOPIK exam in Hongdae. While studying, I came across the word '업체' (company). I have always used the word '회사' (company) before. What is the difference between the two? Does anyone know the difference between these two words? I would really appreciate it if you could provide some examples! When I used to work in Gangnam, I only heard the word '회사' (company)... so I'm a bit confused hearing the word '업체' for the first time. ㅠㅠ I would really appreciate it if you could help me out!
