In less than ten minutes I was messaged back by customer service via email, it's 11:15 pm by the way, and the problem at hand was resolved immediately. This is not a robot or program typing this, I am a real human being, my name is Mike and I totally love PDFfiller.

I have had to upgrade twice to professional and just did again so I could use the features. Billing does not show that the upgrades were put in place.

For the most part, it is a helpful tool. However, I will need to cancel my initial free subscription because one of the documents I would be using on a bi-weekly basis would be for payroll purposes. Unfortunately, when I scanned the document, I was not able to enter numbers in the fields. After several attempts, I checked the hardcopy document and it has a feature, which requires an applicant to fill in the document with a blue pen, something I was not aware of ahead of time. Evidently, the company had the documented protected to only read "handwritten", blue pen entries. I would be using the document as mentioned above for other candidates on a weekly basis and since this product, through no fault of its own, won't allow me to do that, it doesn't serve my business purposes.

I needed to print but had to wait to get ink for printer. Two days later I couldn't find the document to print and one of the Reps from your company helped me find the documents and I was able to print them. Thank you.

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.

I am in Human Resources - this app is so easy to use and is a great time saver as some of the information on the forms are universal. No need to retype huge amounts of information!

I love the product and help via chat has been great but it would be nice to have some training videos to help me get up and running with the product. This is my busy season and it slows me down having to chat for help a video would be so much nicer. Thank you for a great product.

Customer Service Is Great
I used this service while at work and as a functional feature it is great, does what one needs it to do. However, as sometimes happens, I needed to charge this to my personal banking account at the time. When I left the company, I contacted their customer services team via their web based chat service and a kind lady named Monica answered my query. She was very helpful, diligent in helping me locate my details, and took her time to reassure me that the service subscription had ended and evening was a-ok. I know if I ever need to use this service I will come back, and part of the reason is because the customer care was absolutely spot on. Would recommend.
