Action

Why this helps
Invoices can sit unsent after approval because sending requires a separate follow-up step in another tool.
- Turn a clear ready-to-send signal into follow-through.
- Keep the invoice reference and discussion together.
- Reduce the mental overhead of remembering a separate send step.
Setup
Build it in a few focused steps.
- 1Connect Slack and Elorus to Notis once in the portal.
- 2Create the automation in the portal or ask Notis conversationally to email existing invoices from Slack reaction signals.
- 3Write one plain-language instruction that names the designated reaction and requires an unambiguous existing invoice and recipient before emailing.
- 4Choose the Slack reaction added trigger and select a channel for run reports.
- 5Test with one existing invoice and a confirmed recipient, then verify the send result.
Questions about this workflow
Does this workflow create an invoice first?
No. It emails an existing Elorus invoice, so the message must identify the invoice and recipient clearly.
What if the recipient is missing?
The instruction should have Notis request clarification and not send until the recipient is clear.
