Any custom development is beneficial to the company, if only because it does not take on the responsibility for completing the task, but delegates it to a specialist who has been doing this for more than a year. In this case, the business saves money on office rent, project manager, salaries, and taxes. And in the case of custom Angular development, you do not have to look for a developer who has sufficient experience in the field that you need: in outsourcing production, as a rule, there are specialists with extensive experience who have already dealt with similar tasks.
