DocuGen subscription plans depend on the number of generated documents. A document is counted whenever DocuGen successfully creates a new file. If a document is generated in multiple formats, such as Google Doc and PDF, each file counts as one document.
The number of documents is not related to the number of users sharing the document. For example, if you have a board automation that creates a Google Doc and shares it with the board subscribers, this counts as one document, regardless of the number of subscribers.
