I had a very good experience with customer service when I wanted to cancel. I did not realize that there was a form available for no charge. This was a one time thing since in my line of work I really don't utilize this type of service. For those that do, it is a valuable tool

This program is awesome. A little difficult to look up forms at times - but overall experience was fantastic and the finished product looks clean and professional.

Very good. Easy to use. Perfect "side dish" for users who don't need full PDF Writer needs. Has just been saving me hours in handwriting out form information

This is something of a category killer. I'm really glad I signed up for this service. It's great for the property rental market. The UX is a little basic and could use some help but it is functional. (Kevin Kell, UX Architect)

The format of the website was a lot to get used to as there are a plethora of options to go through. Once I was familiar with the site it became obvious this was everything I needed it to be. Great functionality, easy to use. Highly recommend.

Customer Service Is Great I used this service while at work and as a functional feature it is great, does what one needs it to do. However, as sometimes happens, I needed to charge this to my personal banking account at the time. When I left the company, I contacted their customer services team via their web based chat service and a kind lady named Monica answered my query. She was very helpful, diligent in helping me locate my details, and took her time to reassure me that the service subscription had ended and evening was a-ok. I know if I ever need to use this service I will come back, and part of the reason is because the customer care was absolutely spot on. Would recommend.

Perfect Software for Small Business I use this software for my home inspection business to create required insurance reports and include images. It allows me to upload the required insurance form, edit it and add images for the required mitigation and four-point inspection reports. I love that I am able to save my reports, reuse them by editing as needed and organize them in the straightforward filing system. Excellent value for all of the features offered. Easy to use and manage organization. Love the FAX feature, signature, editing and capacity to upload images. Flash feature for uploading images. Settings have to be set and sometimes reset themselves. I use this feature everytime and sometimes the software freezes.

AMAZING CUSTOMER SERVICE - JED I have been conversing with the support agent called Jed, and he has made my vision of this company very clear. Supportive, constructive and quick with the aim to please. He has dealt with my query in such a fast and efficient way that is was delightful to receive a response from him. I just want to thank Jed for the amazing customer service received by him and I surely hope his company sees this and praises him. @PDFFILLER

Well it worked. But, I was tricked into the 30day trial by populating a document you do not own. I could have done this without needing an account albeit "free trial." I don't think I need this service full time. It's way too expensive for an infrequent user.

A fax machine is designed to both send and receive documents, so it has a sending part and a receiving part. The phone line transmits this information almost instantly to a fax machine at the other end. It receives the electrical pulses and uses them to control a printer.
The machine scans the document. It transfers the image of that document into a signal. That signal is sent down a telephone line to another fax machine. The other machine decodes the signal and reproduces the document.
Place the document you want to send in the document feeder. Enter the fax number you want to send to, including and extensions to dial externally, and any international dialing codes. Press Send or Go (depending on your fax machine model)
The sender dials the fax number that the service has assigned to the recipient. The fax machine translates the data and transmits it over the phone line. The service receives the data, translates it into an image file and sends the image to the recipient's e-mail address.
The sender dials the recipient's fax number. The fax machine translates and transmits the data. The service receives the data, translates it into an image file and sends it to the recipient's e-mail address. The recipient opens the email message and the attachment and views the file.
Face Down. When you insert the document you want to fax with the printed side toward the machine, the document's text and graphics are face down against the tray. The fax machine then pulls the document down the tray and scans the document's content.
A fax machine uses a telephone line to send and receive data to create and print documents. They will not work through an internet-based phone line. Be sure to have an active phone line and a phone number for the fax machine, so your machine can transmit and receive signals to create the documents.
