PDFfiller seems to do everything I need, thanks. The only negative, and it's hard to pin down, is that the UI (user interface) seems to be overly busy and cluttered. But it works.

Not sure yet why the W2 would not send to IRS. the button was not lit up after I completed all of my information into the W2 forms. I doubt that I will be able to afford your product due to it billing annually. Also, the price is too high for my budget. -EPOC Bookings

What do you like best?
It is very easy to use and user friendly. It is also easy to add fields and fill them in. When I am creating a document, I can also easily share them with each of our employee accounts. I also like how I am able to remove an employees account from having access to the documents with a click of a button.
What do you dislike?
I wish our technicians were able to use the app without internet service. In some cases, we do not have access to service, and we are unable to fill out our paperwork. It would also be nice to be able to add more than 4 other people to the account without having to get a corporate account.
Recommendations to others considering the product:
It has all you could ever need all in one place. We have used the SignNow and faxing features, in addition to the typical use for pdfFiller.
What problems are you solving with the product? What benefits have you realized?
We are able to keep all of our paperwork in one place, and the technicians are able to access it on their phones. This has made it easier to make sure all technicians are getting the correct paperwork for every job, and with the different accounts, we are able to hold the technicians accountable.

What do you like best?
It is very nice this system can send documents both invoices or signatures in this way everything can be done digitally and pdf preventing others from editing such an important document PDFfiller I love because it allows you to organize each document and send the information in addition to analyzing each file to avoid typing error, be it names, date, price is very complete and I like it.
What do you dislike?
In circumstances the sending of the invoices does not reach the clients correctly and this damages our punctuality, I do not know if it is a failure of my characteristics or it is a system failure, it is a point that hurts, and support is in solutions to that only I must mention this problem, although it is not usual, compared to the rest, the software offers pleasant objectives.
Recommendations to others considering the product:
I have no point or drawback regarding the system, it is for this reason that the characteristics that they already offer us are sufficient for the objective that I need, which is to send invoices to our clients and in this way receive a response through those same emails, whether positive, Negative regarding the comments of the users, however they have been very positive in the response of I see that it is pleasant and saves us a lot of time editing and sending in other software with PDFfiller is done in a single system.
What problems are you solving with the product? What benefits have you realized?
The work is much simpler because now we only have to send the invoices to the clients and PdfFiller does it automatically, in addition to checking them through any emails, all the design and editing of each one of the invoice remains and does not It varies so it is observed from other PDF tools, in this system the design and shipping is done directly in the software so it makes it easier not to have to wait for anything additional to send to the clients, I am happy because it worked wonderfully and time saving is superior and adding some simple features.
