Not here to defend Intuit. Looking at this objectively, a lot of these offers are only available to new customers in the hope of getting them sign up. For e-signature offerings, it's also not uncommon to impose various restrictions, that would make the product less commercially viable. It would be rare to find a company that offers existing customers unrestricted use of their paid commercial services without charge.
It doesn't seem like any of PandaDoc's plans offer KBA. If that is correct, it would mean PandaDoc can't be used for F.8879 whether or not it is free.
Still an AllStar
