First of all, from the perspective of domestic companies developing book software systems, it is also uneven. According to the technical depth, the software can be roughly divided into: platform products (Qingchuan book management software) and non-platform products (other companies except Qingchuan). According to the scale, it can be divided into: large software (Qingchuan), medium software (such as Guang Zhi and Yihua) and small software (Yang Er); Divided by business: group chain (Qingchuan), chain (Guang Zhi, Yihua), network or single machine (Yang Er, Gemini), these are all important factors that affect the development cost.

Estimate the approximate cost of development:

1. Large-scale (Qingchuan scale, platform mode, high-end software): 2-4 million yuan; 15-30 people (architect: 1-2 people, DBA: 1-2 people, platform development: about 5 people, module building: 10- 15 people, test: 2-3 people, copywriting.

2. Medium-sized (Guang Zhi scale, non-platform mode, medium-sized software): the investment is 500- 1 10,000; 5- 10 people (architect: 1 person, DBA: 1 person, software development: 3-7 people) for development and testing;

3. Small scale (two sheep scale, non-platform mode, small software): 500,000-200,000 yuan; 1-2 people (about 2 architects, DBA and developers) for development and testing;

I hope it helps you.
