How to lock PDF and split PDF for Microsoft Edge

Satisfied customer I had my free trial with the company but found that it was not for me. The payment had been taken out of my account. I contacted the company and with in minutes I had a reply and my money was refunded to me. I am retired and do not use my computer to its full extent. If this experience is anything to go by then I am sure everyone will be satisfied with the company. Thanks to everyone for their help.

Not instinctive but... Not instinctive but the simple instructions helped me figure out what I needed to do to get the results I needed. Once I got that, it was easy as pie!

What do you like best? pdfFiller is an excellent product at a great price. The 5-user shareable version is only $15 a month. That is the total for all 5-=users. They also have exceptional support, though you rarely need it. It also gets new features often, such as an inexpensive library of 80,000+ legal and tax forms. Michael Block CPA mblock@blocktax.com What do you dislike? The fax option is $10 a month. It should be $5. However, a $3 third-party fax add-on works with it What problems are you solving with the product? What benefits have you realized? We fill out many forms quickly, which would be very time-consuming.

pdfFiller Has Never Disappointed Me - They are My Trusted Admin Source pdfFiller has never disappointed me with the choice of fillable forms and the ease of completing and saving the documents. For Form document completion, they are my Trusted Administrative Assistant, and I would not recommend any other company for the service they provide.

I really like the service a lot. It is user friendly and intuitive. I like that this also comes with Sign Now so that I can have all the forms I need for my business easy and accessible for me to get electronically signed. I would give it 5 starts except in the Sign Now program the program should default to the text box for people to sign and then have the live signature be on a separate tab, so basically reverse what it is now. It is hard for some people to get to the text box for them to type their signature. I use this all the time in my business and I would recommend it.

Excellent customer service and support Excellent customer service and supportI recently needed to contact them for an issue I had and was helped by Shannen. I used their Live Support Chat, waited less than 1 minute and my problem was dealt with with in less than 5 minutes. Shannen was helpful, polite and made it easy. The fact that this took such little time, without hassle was fantastic. Excellent company to deal with!
