Easy to use but should advise up front that paid membership is required as once document is completed a person is pretty much obligated if they want to send or print...

Pretty easy to figure out - the videos are helpful. I missed the Add Fillable Fields part and I am trying to figure that out. Support Chat was helpful. This is my first attempt to use Send to Sign

I have been help a lot with PDF filler! I can read, analyze, summarize, and even extract text and data from PDFs. If one need specific information pulled out, like tables, certain sections, or individual words, I can help with that too. And if you’re creating or editing a PDF, one can be assisted with formatting suggestions, content organisation, or even generating the text. If the PDF is complex or full of visuals, one can offer general descriptions, but it's harder for me to "see" the images in it. Overall, whether it’s processing, creating, or editing text-based content in PDF filler ,can be a solid resource.

An Affordable and Easy Solution for Businesses Handling E-Signatures As an inexpensive and simple tool for signing documents digitally, pdfFiller is unrivaled in value compared to other solutions offered by Adobe and others. Our company uses pdfFiller constantly to compose property deeds for our owners. We also prepare a variety of documents for our Board of Directors to sign conveniently since they are not onsite always. It does cost more money in monthly subscription fees to have faster access to customer service. At the first time we experienced a technical problem and needed a question answered we did not have the service tier that afforded same-day replies from customer support. This was an inconvenience, but we have since upgraded our services.

I've been using PDFfiller regularly for over 2 years now, and it works wonderfully. I'm able to upload documents, add fillable lines, and get electronic signatures seamlessly. Customer service is also great - prompt and friendly in attending to any questions or issues. Makes running my business that much easier.

My subscription had expired My subscription had expired. I was trying to reactivate my account with a discount offer that was offered to me before my account had expired. Unfortunately I couldn’t seem to figure this out. I was connected to Katrina using the live chat. She explained to me because my account had expired the offer was no longer available. She did however offer me 25% I accepted what was proposed to me. Yet again I was still having problems figuring out how to get this discount link Katrina had sent me. She eventually emailed the link to me because the computer and myself don’t see eye to eye and I can’t figure out how the thing works sometimes. Katrina was very patient and understanding. She helped me figure out my dilemma. Thank youMathieu

We have had a service application on line for several years. People have been printing, handwriting the answers to our application and emailing it back. I just received back my first fillable application and I love it. It is legible and all the answers appear where they are supposed to no more writing up the side of the page because of the limited space for answering.
