Purchase order above X euros needs manager OK first

Approval flows are just 'wait for yes or no before continuing'. The trick: good notification, clear button, a timeout, an audit trail.

Try this first

1. 1Trigger on new purchase request (form, mail, ERP event). Read requester, amount, supplier, description.
2. 2Determine approver via a table: amount x department x stand-in on absence. Hardcoding works once, a table works for years.
3. 3Send approver a Teams or Slack message with Approve/Reject buttons, or a mail with approval link and a context snippet. Wait step blocks until response.
4. 4Timeout of say 48h: on no response, escalate to their manager or mark 'pending' and send a reminder.
5. 5Write every decision (timestamp, decider, outcome, motivation) to an audit table. Later disputes get a paper trail.
