Absolute nightmare!!! Do not use the PayPal option!!! I was using this app for years they kept prompting me to use PayPal for my payments and customers were asking me why I didn't have the PayPal set up. So I figured OK why not? About the 3rd transaction PayPal starts holding (for 21 days) Thousands of dollars of mine that were imperative to running my business. I'll be finding a new app to do my invoices and estimates on. Do not set up PayPal unless you are prepared for random payments held!
