As the title of this review says, paago has helped make my life and job so much easier. I no longer have to devote as much time to billing my customers or waiting to receive payment. I can easily send the invoice, see if the customer has opened it, and when they pay the funds are in my account by the next day. Saves me many trips to the bank. Perhaps the best part about this, I can focus less on billing customers and more on the actual work. Hell, even my customers love being able to pay online.
