good solid editor-- would like to see other payment choices, like a quarterly option, and even instead of relying on automatic renewal, send a reminder email prior to the renewal to ensure the user is still consistently using product
I have tested it and every elements concerning my line of work are deeply thought out and very crisp.
I had a problem of sending a folder but the solution is in merging the files to create one new file to send.
The software is brilliant and less costly than all the competition I have tested.
Only day 1, but so far so good. Love that all my files are stored in one place to access from any computer! Easy to use and email files. Great investment so far!
We love the power PDFfiller gives us to export data filled in to be exported to Excel and manipulated. For the most part, it is a very intuitive program. There are some aspects of set up that are confusing, but customer support is GREAT, QUICK, and seemingly PATIENT. We are very happy so far with its performance.
