Where the agency is providing workflows/service that call external providers (e.g. e-signature, nifty images) that incur a cost.

Instead of having to get the client to set up their own accounts and share credentials; or having to calculate and rebill manually;

Could there be an action to debit the client's wallet balance? (e.g. $0.50 per document sent for e-signature)

Thinking this would be a separate action that the agency would build into a workflow, or call from Zapier - NOT thinking that HL would have to do any calculations or pull cost data from any third parties.
