I'm surprised that someone would pay money for an app to fill out IRS Form W-9. It's a very simple form available via PDF and you only have to fill it out once.

There is no need to re-create the form with a new date if nothing has changed. I routinely give out the W-9 I created 15 years ago, with that date. The form does not get filed with the IRS, it's just for the payer's files.
