Put invoice files in the processing queue
When an invoice arrives in a channel, stage it with Convertapi so the next document step does not depend on remembering to upload it.
Trigger
Channel Message Received

Why this helps
Routine invoice handling involves tiny handoffs that are easy to miss during a busy day.
- Start invoice file intake when the document is shared.
- Make the uploaded file available for subsequent conversions.
- Reduce repeated manual handling of routine documents.

- 5Test with a channel message containing an accessible invoice file.
