Employees conclude contracts with clients on the road. According to the established procedure for document flow, all contracts must have a special numbering, taking into account both the status of the contract and the order of conclusion. A web application was developed for managing the numbering of contracts, issuing new numbers when concluding contracts, as well as changing the status of contracts. The application also allows you to register employees, manage access rights, track all user actions and log them. The application is implemented as a web application for quick access from any device without the need to first download and install the application from the App Store or Google Play. Responsive design allows employees to use the service from any mobile device or desktop computer.
