A: Great question!

Right now, Midly supports up to 2 signers per document (1 internal signer and 1 external signer). However, the multi-signer feature is already in development and scheduled for our next sprint—so expanded signer support is coming soon.

As for how signed documents are counted:
Even when we roll out multi-signer support, a document with multiple signers will still count as one signed document, not multiple. That won’t change in the near future (within the next month or so).

We’ll be sure to share an update as soon as the multi-signer feature goes live!
