1. Set up a technical team to develop it by itself. The required personnel include product manager, framework engineer, JAVA, PHP, front-end, back-end and test engineer. The development cycle is 1-2 months. Personnel cost10-200,000 yuan, excluding post-maintenance costs. (Not recommended)
2, buy other people's small program source code, configure the server yourself, and then find technicians to maintain it full-time. The source code cost is generally 10000-30000, the server costs at least 3000 a year, and the maintenance cost is over 6000 a month. (Not recommended)
3. Use third-party applets and purchase accounts of third-party applets. The total cost varies from 2000 to several thousand yuan according to your own needs. You don't have to worry about technical maintenance or building a server. You can use it. You can also design a store and bind the official WeChat account according to your own construction needs. (recommended)
(Addendum) As for how to choose a development company, you can refer to the following points:
1. See if the company has official website. If an internet company doesn't even have a website, it is conceivable that the possibility of a leather bag company will be even greater.
2. Do Baidu search developers have any negative news? If Baidu search directly appears keywords such as liar, cheating and other related words or negative news in the search results, then the company will choose carefully.
3. Inquire about the company's industry reputation and find some companies that have cooperated with the company to inquire about the situation. Generally speaking, this evaluation is solid, and it is difficult to discard the false and retain the true.
4. Look at its case. If a company doesn't even have a case of software development, it is either a newly established company or a company that has just started to do this business. Either way, it shows that the company has insufficient project experience and its strength is difficult to evaluate. If it cooperates, it is probably a guinea pig.
