Zapier is an online tool that has been created especially for small and medium sized businesses that need to unify their online presence. The software goes to work to automate services between different devices and works so smoothly and intuitively that it is ideal even for novice users. However, it should be noted that the level of service that is provided with the free version of Zapier is a bit limited and people who discover they require the extra features may prefer to pay the monthly subscription for the full version.
