It's somewhat costly, but it works. I have no idea whether it's worth it. I needed to get something done, and it was easy to find, so it was worth it to me. I certainly was glad there was a half price sale.

this is a app that i will definitely continue to use. i was able to use without having to try to figure out how to use. would highly recommend for everyone.
leanna m
The log in process is a little clunky. I have not been able to copy paste a field in the template creator. I have 30 fields or so that will each have the same sized field, I should be able to duplicate the specific field a number of times and paste. No?
Jeff
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.
