This is my first experience with PDFiller.....so far, it is good. However, I do not like that there is not a contact # to speak to someone in customer support. .

It's been great as a company that has numerous Prevaiing Wage projects going on at the same timer, PDF filler has enabled me to make changes on WH347 forms. PDF filler is an extreme help.

The program very intelligently interprets PDF images, creating fields in just the right spot for us to type our responses in, while avoiding the print-write-scan-save cycle.

PDFfiller - One stop tool for PDF Editing
Our organization use PDF Filler for contract completion with our clients/vendors. It allows us to insert a place for digital signature that is legally binding in the documents. Saves a lot of time and money from both sides.
PDFfiller is best tool for pdf editing online. It includes plethora of functionalities for editing pdf. Some of the functionalities I like include add text, note, watermark, redact, draw, add images/videos, textbox, date, checkmark, search and replace text, spellchecker, undo and redo, copy and paste, and pdf toolbar, add branding and Document signing and many more feature. PDFfiller supports integration with major cloud platforms including Dropbox, Google Drive, One Drive and Box. One of the best and easy to use tool for filing and storing all sort of forms electronically. Allows you to convert pdf files into other formats such as Microsoft word, excel and ppt. 'Send to Sign' feature is a boon to corporates and legal industry.
Some of the advanced feature require a great learning time from the end user. Sometime you would not get expected results while converting a Pdf to word in terms of change in formatting which is difficult to edit. Sometimes the tools is slow while working on large size files.

I started the free trial, and my document has trouble being edited, so I hope this can be sorted. The help was quick and efficient and Kara escalated it when she knew there was a problem, so top marks there. I just hope the techie team can sort the font.

SIMPLE AND EASY TO UNDERSTAND FOR PEOPLE WHO ARE NOT TECH SAVY
ITS GOOD BUT PRICE SHOULD BE MADE RESONABLE SO THAT MORE PEOPLE CAN AFFORD AND USE YOUR TOOLS. FOR PEOPLE IN INDIA IT IS STILL EXPENSIVE. IF YOU REDUCE YOUR PRICE, IT WILL BE AFFORDABLE TO MANY AND YOU WILL HAVE MORE CUSTOMER VOLUME IN INDIA THAN ANY OTHER COUNTRY. THIS WILL HELP YOU GENERATE MORE REVENUE.

Over the top excellent customer service
First and foremost i want to express the excellent customer service i received from Daniel yesterday evening to the wee hours of this morning. i couldn't figure out how to correct or update a form and my computer literacy was no where to be found. I ask Daniel to please have patience with me and he went above and beyond my expectations. Daniel not only spent hours on trying to help me figure out the issue he also walked me through how to send him a screenshot of the issue! Not once did i ever feel rushed or uncomfortable especially when i wasn't able to follow his instructions. He not only walked me through fixing the form; he also helped me fill in some fields i was unable to do. The most awesome experience was he stayed on the line with me the entire time!!! This is the kind of customer service that is such a rare commodity and i was blessed enough to be on the receiving end with Daniel. He is absolutely an asset to this company and greatly appreciated.Warmest Regards;Rhonda Wright
