Freelance is a promising direction in the field of employment and small business. In many Western countries, it has already become widespread, while in Russia it continues to grow rapidly. In this article I will discuss the basic principles of the freelancing industry.

First we introduce the basic concepts:
1) Freelance Exchange
Exchanges are sites that organize the interaction of freelancers and customers. They are essential elements in the work of the freelancing industry. Without them, there would be no organized interaction between freelancers and customers.

2) Freelancers
Freelancers - people who are looking for jobs and projects for the purpose of employment and profit. They are the target audience (on a par with customers) for freelancing exchanges.
3) Customers
Customers are people whose goal is to implement the project using all the advantages of working with freelancers.
4) Information sites
Sites providing information to both freelancers and customers. The goal is to attract interest in the field of freelancing.
Scheme of work in the sphere of freelancing:

In the established market, freelancers are always more than customers.
Freelance Exchange Operation Scheme:

It is worth noting that the exchange has a percentage of transactions conducted on it - this is one of the parts of the income. Also, the income can be obtained from the granting of various privileges to freelancers and customers.
Now we define the main tasks for market participants:
The most optimal task for a freelancer is to gain access to the implementation of the most profitable and promising projects. In a real situation, it comes down to gaining access to the implementation of fairly profitable projects. For many low-skilled and inexperienced, it comes down to the ability to carry out any paid project that they are supposed to cope with.
For the customer, the main task is to implement the project in the most qualitative and profitable way. In different situations, different customers may emphasize profitability or quality.
The task of the exchange is to get the largest number of clients (customers and freelancers) and provide them with the service at the best price.
For clarity, here are some quantitative characteristics of the freelancing industry in the Russian-speaking segment of the Internet:
- Number of significant exchanges: more than 66
- Number of freelancers on the largest site: 270680
- The number of projects per day: more than 300
- Average project budget: 18571 rubles
In the field of freelancing can be identified many interesting problems and phenomena. Here I have considered only general principles. In the future, I plan to explore in more detail some topics, such as the development of the freelancing market, the comparison of different regional segments, a more detailed study of quantitative characteristics, and many others.
