Hi, I am in my second year as a lawn care company and have around 40 customers I service all summer long. I use yardbook.com and there app to keep myself organized and also bill most of my customers through the site/app. Last year I did not owe anything in taxes because of all my initial costs. This year however I assume I will owe uncle sam at the end of the year and so have started putting money away for that. I noticed the other day built into my invoice generator I have the option to add sales tax onto my invoices. Is it pretty standard to add sales tax onto your invoices in the lawn care business? I am still solo right now but just about ready to start growing and realized I need to get my business model in line before I grow ahead of myself. Thanks to any and all suggestions/advice.
