It's easy enough even if I'm not an expert in excel but just know how numbers work! The layout of all my forms are organized together so no matter what form i am working with everything flows smoothly from one project estimate sheet straight into another without having any errors or confusion as far back tracking goes!! Also being able use this program outside their office hours makes me feel more comfortable using there services because they can't be around 24/7 which helps keep costs down since we don’t always require them during business days.
