As freelances we need to keep track of ourselves both for financial reasons, and because we can lose track of time. For this sort of thing we need a set of tools and the ability to use them. When you think about what you need to help you, you can make a list and almost always the tools you need are freely available on the internet. Sometimes they are paid programs but more often than not free alternatives due to the open source programs. The spirit on the internet is truly remarkable with the number of people who are prepared to share their hours of work for the love of creating something they can share.
One item we need is a project management system if we are going to work with other designers on the same project. The chances are that although we are freelancers but because of the nature of web design today we are probably working in collaboration with others, and as a result we need to have a collaboration and project management program such as SmartSheet. You can try this free but there is a monthly cost to it. They also have a outsource program which they call crowdsource which is where you can find freelancers supplied by them for a fee to do the work you want with you in charge of the way things are done.
Another web analytics program is Clicky. This is not a free program but does give you a host of information and unlike Google analytics it does it in real time. However, then so does the analytics program you host on your own website, Piwik. The stats are real time, and it is simple to use and gives you far more information than most of the others. You will have to make a decision as to which of the three you want. You might want to give the free one a try first and then look at one of the others. To be honest if I was to choose between Google and Clicky, I would choose Clicky.
