Spreadsheet Question

Hey guys. I’m a fairly new business owner, although my family has been tearing off and putting on roofs for about 35 years. I am getting more serious about the marketing and logistical side of things to help the business grow. One of the things on my list that I need to get done is to create a workflow spreadsheet. I have a very basic one so far. I was wondering if anyone here happens to have one that they could share.

Thanks.
