A no-show isn't just a missed appointment, it's a slot you could've filled with someone else. Most businesses send zero reminders, or one, manually, if someone remembers.
Built a free fix:
→ Checks the calendar every 30 minutes for what's coming up
→ Sends a reminder 24 hours out, and another 2 hours out
→ Each one includes a one-click reschedule link instead of silence
→ Google Sheets logs every reminder sent, automatic audit trail
Result: two reminders per booking, zero manual effort, and a reschedule link instead of a dead slot. No-show rates run anywhere from 10-30%+ depending on the industry — this is the cheapest lever to pull on that number.
If you're a Consultant here with a client bleeding slots to no-shows, dm me and I'll build it for them. Free, they just cover their own subs/usage.
