Welcome to Software Companies in United States
In short, they build specific solutions. For example, let´s imagine you are a casino manager and you want to improve how people access to it. You have a list of people who are prohibited from entering the casino, and you want a system that would filter them and not allow them access without having to do it manually. A software factory may build a software which involves using a QR code or a barcode for the identity cards. The code is scanned by a reader and the system searches for coincidences within the database of people with prohibited access, in case of being on the list the gate does not allow the passage; if it is not on the list, the porch opens. This will allow the casino to save a lot of time, as the staff doesn´t have to get the ID, find it on the list or not, and open the gate or not. Another feature is that if the person requesting to enter the casino is in the database, an alarm sounds and the staff is notified.
Another example would be a solution for a gas distribution company. A system could be developed that would allow them to manage and notify them of the maintenance dates of the cylinders and the certification dates of the valves, facilitating their production process.
Many times, according to the programming languages or framework that software factories use, economies of scale can be made, which means that several lines of code are built in a software, and then, that code can be reused to create another connection that allows, for example, an e-Commerce, or a production process, such as when a work order is started and, at the end, an invoice is automatically generated.
Something fundamental for software development agencies is that they are not only capable of developing the idea that the company has in mind, but that they are also capable of contributing other ideas, always looking for the best solution. The work team must contain different profiles, graphic designers - who are concerned with developing attractive ideas, where the user has a good experience when using it, taking usability as the main focus -, there are also programmers, with the ability to reuse a code, and to implement tools; that is why it is important that the team is constantly training. The leadership capacity of the boss and his creativity also play a fundamental role, because he will also be raising ideas and constantly looking for better solutions, challenging the team to improve. All this allows to solve the requirements that each user has.
Do not limit yourself, create your solution and develop it with experts.
