There are three main ways to develop a small program. Let's list the approximate cost of each way:

1. Set up a technical team to develop it by yourself. The required personnel include product manager, framework engineer, JAVA, PHP, front-end, back-end and test engineer, and the development cycle is 1-2 months. The personnel cost is 511,111-111,111, and the later maintenance cost is not counted. (not recommended)

2. Buy other people's small program source code, configure the server yourself, and then find a technician to maintain it full-time. The source code cost is generally 11111-31111, the server costs at least 3111 a year, and the maintenance cost is more than 6111 a month. (not recommended)

3. Use a third-party applet and purchase an account for the third-party applet. The total cost varies from 2,111 to several thousand yuan according to your own needs. You don't have to worry about technical maintenance or build a server. You can use it when you bring it here, and you can also design and make it according to your own construction requirements.
