There are many methods of valuation. The evaluation price of each method is also different. A year's financial data can be adjusted artificially. There is no way to give an accurate estimate from your company's annual turnover and net profit. This has a lot to do with your business situation, fixed assets, inventory, repeated purchase activity of customers, the growth of the company in recent years and the growth of the industry in the next few years. Even employees and brands have a certain relationship.
If you have to give an evaluation price, the range is relatively large. Personally, I think your company's valuation of 3 million-10/00000 is reasonable. The information is limited and it is impossible to judge. I hope it helps you!
