How to develop a small program in milk tea shop

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

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 period exceeds 1-2 months. The personnel cost is 500-65438+ 10,000 yuan, excluding the later maintenance cost. (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, and you don't have to build a server. You can use it with it. Can also be designed and manufactured according to their own construction requirements. (recommended)
