I like how easy it was to learn because there are so many features but not too much of them at once! It's also very intuitive which makes using this product really simple for anyone who has used similar programs before or even those just learning about estimating/RFQs etc. The free version offers more than enough functionality however if you want better customization options then paying an upgrade fee would be worth considering as well. This program helps me keep track with my quotes easily without having multiple spreadsheets open up each time i need some information from another quote.
