It all comes to balancing out all pros and cons, and choosing the best option in each and every case. Outsourced IT support has its difficulties, which can appear challenging. First and foremost, it's quality control. When you turn to a remote partner, you have to make sure he is willing to learn the specifics of your business (and is capable of understanding tech details). It's going to be a long learning process. Onboarding on such projects takes about 3 months, if not more. Another difficulty you'll quickly run into is a necessity to cover difficult and complex cases. There will always be clients who run into unique and complicated issues, and only your in-house developers can help with those unicorns.
