I build automations for small businesses. One client spent 4 hours every Monday pulling numbers from 3 dashboards into one report. We moved it to one n8n flow. It runs every Monday at 7am, pulls the same 3 sources, writes the report to a sheet, and emails it. First version took me a weekend. The trick that made it stable: make it fail loud. If a source is down, the flow sends an email that says 'this step broke' instead of sending a half-empty report. Silence was the old problem, not speed. Now it's 12 minutes of checking instead of 4 hours of copy-paste. One weekend to build, about an hour a month to maintain.
