The ranking rule
Frequency times cost of delay times ease of build. A task that happens 50 times a week, costs money when it's late, and connects to tools you already have goes first. A task that happens monthly and nobody minds doing goes last.
1. Lead response
Every new lead gets a reply in under 60 seconds. This is almost always the highest-return automation in any business.
2. Missed-call text-back
Instant text to any missed call. Trivial to build, immediate results.
3. Appointment reminders
Cuts no-shows, which directly protects revenue you've already earned.
4. Invoice reminders
Polite, scheduled, with a payment link. Gets you paid faster without awkward calls.
5. Review requests
Sent at the moment of completion. Reviews drive the next lead.
What to leave for later
Internal reporting, complex multi-system syncs, and anything where the process itself isn't settled yet. Automating a messy process gives you a fast messy process.
