PandaDoc is good at what it does. The thing is, most agencies do not actually need a contract tool. They need a place to do all the things their work is, which is rarely one thing. Here is the honest version of where the seams start showing.
What PandaDoc is built for
PandaDoc is at its best when the work fits a clean, repeatable shape: standardized contracts, sales orders, NDAs, recurring pricing pages, and e-sign on top of all of it. For sales teams shipping the same document a hundred times a month, that is exactly what you want.
Agencies do not have that shape. The proposal is a custom argument. The contract is sometimes the same shape and sometimes not. The report changes every month. The deck is its own animal. The client portal is its own job. A tool built for one shape covers a slice of that and leaves the rest as someone else's problem.
Where agency work asks for more
Three places, every time.
First, the variety of document types. A proposal that needs a real editor for scope and pricing is not the same as a contract that needs careful clauses, which is not the same as a quarterly report that needs charts. Trying to live inside one editor that was built for the contract shape makes the other documents feel awkward, and clients clock that awkwardness even when they do not name it.
