How do I create an invoice in Wave from a workflow?

Short answer: You can create invoice in Wave by hand from its own interface, but it won’t repeat itself. On TinyCommand, add the Wave Create Invoice action to a workflow, map its 2 inputs from any upstream app, and it runs automatically every time the trigger fires. No code, and a free tier to start.
