I have tested it and every elements concerning my line of work are deeply thought out and very crisp. I had a problem of sending a folder but the solution is in merging the files to create one new file to send. The software is brilliant and less costly than all the competition I have tested.

I paid for a year subscription to PDFfiller because I needed to fill out a form for college and employment applications. No stress like trying to add a text box in the correct place when using other programs. I have used it more than expected. Very pleased!

PDFfiller has been an excellent tool for both personal and professional uses. I especially like that I can send documents and get a confirmation receipt once the recipient downloads it.

I made a mistake and bought a year subscription instead of one month as I needed, I immediately emailed customer support and thought I would be waiting days for a reply if I was lucky, but to my surprise I received a response within 2 minutes. She offered to change my subscription and refund the rest of my money, I of course excepted and they changed it immediately! ***** ******** for your amazing customer service! And your forms, that have been time saving!

It's essential for digital nomads It's essential for digital nomads. Since my base is in the US. I rely on these solutions to continue operations in the US from abroad. I would integrate payment systems, especially with the banking networks to be able to send money orders or checks physically. And I would suggest connecting with virtual offices to be able to interact with clients in a virtual office setting. I'm thinking a virtual secretary solution... just some thoughts to improve. Abe
