Please rethink your Zapier pricing model. I've been using PandaDoc for years (from back when it was called QuoteRoller) and for a small business this is getting too expensive, and Google docs basically can handle all this for me.
Please rethink your strategy for charging these Zapier-generated documents. It won't take Zapier users long to work out that they can do the same service automated in Google Docs, which doesn't charge a premium for documents generated from Zapier.
