If you are just a self-employed person or a small shop opened in partnership with friends, there are many free software for purchasing, selling and warehousing on your mobile phone, which can meet your needs. Hotels and restaurants can use the business of "what life is like, the rest can be used", such as how to purchase, sell and store, which can be used by many people and shops. If it is a large garment factory with specialized financial management, you can use more professional software, such as UFIDA software, housekeeper and so on, but this kind of software is more complicated, and some of them need professional training to be used smoothly. What software to use mainly depends on what store you open and your bookkeeping needs. It is best to find the one that suits you.
