I may be an idiot but it isn't the most intuitive experience I've had. I have been under pressure to produce so that may have something to do with it.

it is great. I can mark where I need clients to notice or sign. Would be interested to know how the rest of the programming works so I can use more of it.

Very Easy to use and beneficial. Worth the year subscription. A lot of features to choose from. Everything you need for a functioning office to succeed. Although, I wish the Fax Features would be more affordable a month or included with the yearly subscription. I am paying half the price for Fax with another company but would love to port my number and come on board with PDFfiller for the convenience and functionality of integrating my Faxes along with my other documents all in one place. Love this software. I'm excited to of found it and look forward to putting it all to work for me. www.LazcoIncomeTaxService.com
