I do landscaping and am wondering about how to report deductions for things that I buy in bulk (such as fertilizer or irrigation tubing) and use here and there on projects. I don't charge my clients necessarily for the stuff but figure it into my hourly rate. Would this be considered cost of doing business or goods sold? On turbotax if I select good sold, it asks if I have inventory and says my inventory from 2014 had to be the same at the beginning of the year as the end of the year. What? I don't have a warehouse full of stuff so I don't have "inventory" so I don't know how to address this. thanks.
