Hi chickeninnplus.
Tracking your expenses and costs for your projects is what QuickBooks is all about. I'd be happy to help point you in the right direction for this.
In order to know how to best manage your costs and overheads I recommend reaching out to your accountant as they are trained in how to make these kinds of entries. If you don't have an accountant no worries. You can find one near you by going to our find a pro advisor page. Once they advise you of the best way to manage and enter this information let us know and we'd be happy to walk you through how to enter it in QuickBooks Self Employed.
If you have any questions let us know and we'd be happy to help.
