I am having some trouble navigating. I want to bring back 2 copies of a form which I printed but want now to make minor corrections. Can't seem to find the way bac. Maybe I did not save them properly

I have been using this program for almost 2 years now and it is amazing! I have uploaded all of my work documents/forms so I no longer have to hand write every single thing. Not to mention I am saving money by not having to purchase any paper and more importantly I don't have to purchase any printer ink.

It made a nice document. The only thing that is challenging is that you have to go line by line instead of having an option to change more than one line.

What do you like best?
The customer support is phenomenal. They always answer quickly and fix whatever issue i have. The actual software does it's supposed to and increases my productivity x10. There are features included to import government forms easily or you can upload your own. The templates are easy to create and to make new documents using.
What do you dislike?
The amount of options can be overwhelming. It seems like the product can do so much and would take a long time to fully understand or use. The speed of the application is actually pretty fast but its not a literal immediate load time.
Recommendations to others considering the product:
Learn to import your forms directly from their bank of existing forms. Be careful when editing fields so that you don't overwrite existing functionality. If you need help don't hesitate to do a live chat and screen share. Their chat agents will fix any issue you have. I've had them help me multiple times.
What problems are you solving with the product? What benefits have you realized?
We use it to fill out government tax forms, specifically form 1098c for our nonprofit organization. The primary benefit is a secure place to share and store all our documents that we can search and edit when we need. This software saves us an immense amount of time. It provides a method to update and edit documents in minutes with recurring pages that would otherwise take 4x times longer fill out and complete. We generally only use this form an IRS form specifically but i can see the use case for many types of companies and situations.

PdfFiller ou rien Très bonne expérience. Au début j'avais un peu de mal mais tout est venu très vite. Je l'utilise essentiellement pour ma paperasse professionnelle avec les administrations lorsque j'ai besoin de signer.Non seulement on fait des économies de papier mais en plus si on n'a pas d'imprimante ou qu'on se trouve sur le mobile ou la tablette on peut utiliser cette application. C'est top ! Pas besoin d'avoir un logiciel qui prend de la place dans l'ordinateur ou autre. Pas de risque de chopper un virus en téléchargeant !Facilité d'utilisation hors normes ! Je ne vois aucun point faible pour le moment. Si c'est le cas j'en ferai part.

What do you like best? I like how easy it is to use and all my documents are automatically saved. This has increased my productivity so much being able to combine documents and have people sign. What do you dislike? There are a few steps to save, print, or download to your local desktop which can be a little time-consuming. But I also appreciate that it verifies with you that the correct function is happening. What problems are you solving with the product? What benefits have you realized? The ability to edit and few pdf documents. I really like that pdf's can be combined and shared. There's so many functions of pdf filler that is so helpful to help me be more productive.

What do you like best? Very easy to upload my documents, clean them up and edit and add information. I like that it stores all my documents that I've worked with. What do you dislike? Printing from the site has so many print windows to go through. Recommendations to others considering the product: Easy, Cost Effective. There is not a lot of features to overwhelm someone. For us, it works great as we only need to edit information on new documents but only receive the originals on paper so this is the easiest to get them filled out, and into electronic format for future use What problems are you solving with the product? What benefits have you realized? We complete our bid documents on this program and the PDF filler keeps the information professional, legible and I can go back and edit as needed. Easy and Cost effective solution for our small company
