In an effort to ward off lowballers....... If this hasn't been brought up before, I am posting internet based billing software. There are no kickbacks for myself nor do I receive commissions or compensation in anyway, shape or form. I am not saying I discovered it as I am sure someone else has brought this to lawnsite (I am just too lazy today to search). Intuit billing manager. Do a google search or http://billingmanager.intuit.com/billing/welcome.url It is completely internet based, FREE and tracks late payers, allows you to choose templates and is completely user friendly. The invoices are professional in every respect. A cool template is one that allows you use "window envelope" invoices. I chose this particular software as it allows email sending without setting up your own PC. You can use it on ANY computer which means you can print one from your customers house if need be. I sent a letter out to EVERY customer informing them that we are saving on fuel expenses by cutting back in other areas and we will now email invoices and the customer can click and print their own...we save on ink now too. Good luck new guys!
