How can Jobber help me grow my business?

I am a fairly new business and I am still finishing the detail of my operations. I have been using the basic plan from Jobber for my bookings but I did not find myself using the Marketing suite very much when I first purchased a plan. I believe it is because I was still figuring out how to run my business operations. My question is, what is the best marketing move for me to do as a relatively new business owner using Jobber with limited resources like funds and a small client base.
