Manage, edit, sign and notarized pdf forms easily I can easily create, manage and edit my pdf documents with Pdffiller. It is a cloud storage where you can quickly login through facebook or google account. Open your pdf and edit it easily. You can convert your document to the available templates fit for your form and objectiives. I like it because i can open my documents in a web browser or through its desktop application. You can easily create a form where the recipient can put his or her signature by using its send to sign tool. You can share your document. You can email it. Whats best is that you can have your form notarized. Pdffiller has different plans and price is affordable depending on the number of users. However chat support or customer support's turn around time to resolve issue also depends on your plan. If it is just basic, expect support to attend to you within 24 hours. If you have the premium, then it will be instant support.

Good Experience I had a free trial with pdfFiller and while the product didn't fit all of my needs the support was very responsive and helpful. It was a good experience all around.

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

user friendly and practical, what would really differentiate would be the possibility to use the app when offline and automatic synchronization once online.
