This app fills the bill! (Pun intended

Im a remodeler.
When I finish a job, customers will ask if I will mail them an invoice. I tell them I can do better than that, Ill send it right now.
With this app, customers are often surprised and pleased when I am able to email them an invoice on the spot. A few seconds later, they have it on their device, either ready to be paid, or if theyve just given me a check, marked as paid. They love it, and so do I!
