Many software development companies out there pretend that they offer a complete range of software development services to their clients but unfortunately, that couldn't be more far from the truth. There are two reasons why I used the "unfortunately" term here. One is because, obviously, these companies fail to cater to each and every need of their clients and the second one is because offering a truly complete range of services is essential for long-term success. I will elaborate on this also, below.
There is no doubt that the IT landscape has evolved to such a scale that it now represents the pivotal industry on the planet. Basically, everything revolves around it and if you are going to succeed with any project, you simply can't ignore it. Now, many of your competitors know this also which means that the IT environment is currently as ruthless as it gets. Playing on such a field means that you have to take advantage of any leg up that you can muster and collaborating with a capable company is one of them.
Below I am going to take Developers Global as an example and present their services to you so that you can understand what a complete portfolio looks like. First off, let's start with professional web development. Basically, no matter what you do, you have to have a website. This is common sense so I am not going to vex you with details about this anymore.
Second on the list is of course mobile programming. If your project has a social side to it, the first thing that you should do is take a good look at mobile application development and find a way to engage mobile users. Feel free to also draw upon the collective wisdom of the Developers Global mobile development team in order to make your website and your mobile app consistent.
If your project is of a bigger magnitude, you're going to need desktop applications also. Make sure that the company you hire is also able to provide desktop development for a better implementation. Last but not least, you'll want to advertise your business and nothing does this better than a Facebook marketing campaign which should also be handled by the company you employ.
