Taking a while to learn how to do this, but it is great. Questions: (1) Tell me how to transmit this electronically to you. (2) May I use the same form to register different Scripture we publish? Most elements in this first registration will apply to all that we register. (3) How do we handle the fee for registrations, and what do you need in addition to this and a fee? (4) I have a hearing problem, and need to be in e-mail contact with you (life3@gmx.com). Leon Taylor, Chairman of Vietnamese Bible, Inc.

What do you like best?
It gave us the opportunity to place our registration in a fillable format.
What do you dislike?
A user cannot save their progress and must complete the entire form in one sitting.
What problems are you solving with the product? What benefits have you realized?
Easy for parents to use. Parents no longer need to print out the document and send it in with a hard copy. It also gives us the ability to file a digital and hard copy if we so choose.

Accounting Assistant This software made it easy for me to complete a single 1099-MISC that i needed and that i wasn't able to use my current software for. I was able to quickly create the document and send it out to the necessary party on a time crunch. This would not be good to use for a large amount of 1099's but, it did meet my needs.

Very helpful to be able to type into… Very helpful to be able to type into pdf docs. I did originally find it difficult to work out how to save and print the documents. Eventually I saw the little down arrow which had the options there. Thanks.

What do you like best? This platform is an online pdf editor, electronic signature manager and creator of PDF forms, you can send them by fax, obtain complete copies of the PDF forms sent and signed, you can also automatically extract data from Excel, CRM or database data. Share the documents by email, social networks and you can also place them on your company website. What do you dislike? We have not had any problems with this platform, the performance has been satisfactory, the pdf files are relatively basic and do not present any type of error, it seemed a good option after using other platforms with negative results, but this has been totally different. Recommendations to others considering the product: It is fully recommended, the results obtained have been very gratifying and satisfactory. You simplify a large part of the work that allows you to save time even you maintain a constant work flow. Share documents through email, social networks among others. In general it is very complete and a good option for all companies. What problems are you solving with the product? What benefits have you realized? We use PDFfiller, to obtain and receive forms from our clients, sending e-mail is excellent to communicate, this drastically reduces follow-up time and interaction failures with our work team. We also obtained a significant increase in work flow since I simplified the handling of many documents such as W-4 in addition to insurance renewals and bank authorizations. We perform a conversion of file formats such as Word to Pdf daily and with ease, we are happy with the results.
