Make invoice follow-ups easier to remember
When a team member flags a specific payment follow-up in Slack, send the intended contact a concise, respectful text.
Trigger

Why this helps
Payment follow-ups can sit in internal conversations without making it into the next day's task list.
- Turn an explicit follow-up into an immediate next step.
- Keep the message connected to the invoice context in Slack.
- Reduce the mental load of tracking who still needs a reminder.
Setup
Build it in a few focused steps.
- 1Connect Slack and ClickSend to Notis once in the portal.
- 2Create an automation or ask Notis to send a payment follow-up text for an invoice explicitly flagged in Slack.
- 3Describe the qualifying flag, approved recipient, and respectful message in one plain-language instruction.
- 4Choose Channel Message Received, select a run-report channel, and test with a real appropriate example.
Questions about this workflow
Does this send to every customer mentioned in Slack?
It should only act when the post clearly requests a follow-up and identifies an intended recipient.
Can the text include an amount or invoice reference?
Ask Notis to include only the relevant details stated in the Slack message.
