Agent mail Invoice Reminder for Slack
Give every invoice a clear next date before it disappears into the inbox.
Trigger
New Email Received
Trigger for new emails in an AgentMail inbox
Action
Create a reminder
Creates a slack reminder with specified text and time; time accepts unix timestamps, seconds from now, or natural language (e.g., 'in 15 minutes', 'every thursday at 2pm').
Why this helps
An invoice can arrive during a busy day, then the due date is rediscovered only after cash planning becomes urgent.
- Capture the payment decision when the invoice arrives
- Surface missing due-date information instead of silently guessing
- Keep the reminder beside the work where payment follow-up happens
Setup
Build it in a few focused steps.
- 1Connect Agent mail and Slack to Notis once.
- 2Describe how to create a Slack reminder from a new invoice and what default to use when no due date is supplied.
- 3Choose New Email Received and a Slack channel for run reports.
- 4Test with an invoice containing a due date and inspect the reminder.
Questions about this workflow
What happens when the invoice has no due date?
Notis uses the explicit fallback in your prompt or flags the missing input; it does not invent payment terms.
Can the reminder include the invoice context?
Yes, when that context is present in the received Agent mail message.
